Failed Dacor Touchpad Causing F1 or F7? CPD,CPS Built-In Ovens

Are you having trouble finding a keypad for your Dacor built in oven? Don’t worry, there are options!  For a fraction of an oven replacement you can have the functionality restored to your oven and avoid multiple thousands of dollars to replace a built-in oven. A simple keypad problem can turn into a headache due to a ‘no longer available’ (NLA) or obsolete touchpad. Most parts for Dacor ovens are available for a very long time but the touch pad seems to be an exception to this. This control panel is made of a sealed membrane switch that wears out over time. Once this part fails, the oven can become unresponsive, beep randomly or throw error codes like F1 and F7 codes.

Cross-Referencing Oven Control Vocabulary: Control Boards, Clocks, Timers, ERCs, EOCs, Display Boards, Relay Boards, and Touchpads.

 

A valuable vocabulary lesson from a PCB repair company

The point of this blog is to dispel the confusion surrounding the nomenclature of oven control systems.

 

We are talking about the electronic circuit module that is generally mounted behind the control panel, containing the display which shows time and often the status of the oven. More importantly, however, control boards do exactly what their name says – they control all the functions of an oven.  They are also referred to as ERC (Electronic Range Control), EOC (Electronic Oven Control), Controller, Control Module or AssemblyPC(Printed Circuit Board), or PC Card.

Technicians will often refer to these as clocks or timers, since the clock is a prominent feature of oven control boards. And, before electronics were introduced to home appliances, the time was kept by a mechanical clock and the oven was controlled by a separate mechanical system. The clock often failed and needed to be repaired.

Today, oven control boards fail frequently and this company offers better repair service than anybody else! 

There are also many instances of one oven employing two or more control boards that govern different aspects of the oven. For example, there may be one board that contains the display and connects to the keypad, and there will be another board which manages the power of the oven elements and other hardware. In this case, the first board is called the Display Board, Display Head, or Control Head, and the second board is called the Power Relay Board or Appliance Manager.

We always recommend that all boards be sent in for inspection/repair if your oven is having control problems and it contains more than one board.

“How do I know if my oven has more than one board?”

Hopefully you have access to the tech sheet for your unit – sometimes they are taped to the back of the appliance. A tech sheet will contain a wiring diagram which shows all the connections between oven hardware and electronics. It will separate a display board from a power relay board should the appliance have multiple boards.

If you don’t have access to a tech sheet, don’t worry. Another easy way to tell is by identifying whether or not your control board has any relays on it. Relays are electronically controlled switches, and oven control boards generally use them to put high voltage on a heating element, among other things. These components are usually the bulkiest on a control board (aside from a transformer if your board has one). They are often black or white, and their shape is usually rectangular or boxy. They are almost always located right next to the wiring tabs where the colored wires that go to the heating elements, door latch, etc. attach.

If you don’t see anything like this on your control board, then there is an external relay board you haven’t found yet. However, the main control board (which almost always has the display) does control the relay board, and it has to connect to the relay baord to do so. There will be a wiring harness attached to the main control board which has several wires leading to the relay board. Following these wires is the easiest way to locate an external relay board. If you have a double oven with external relay boards, there is likely a relay board for each oven.

Remember, these relay board control high voltage, so if you’re digging around in your oven to find a board, MAKE SURE THE POWER IS OFF.

Lastly, there is the means by which you control your control board – the touchpad (if your control doesn’t have buttons built into the board).  This can also be referred to as the Keypad, Control Panel, Button Panel, or some other similar term.  Often, the touchpad is built into the front panel behind which the control board is mounted.  Sometimes, the touchpad is part of the control assembly.  Regardless, the touchpad and the control board are separate entities.   I’ve never seen a touchpad failure be the result of a control board problem.

What is a touchpad failure? Sometimes the control board will throw an error code: F0, F1, F7, F9, E0F2, E1F1, and  E1F2 are all common touchpad failure codes.  If the board is powered up but pressing buttons yields limited or no response, it’s likely the touchpad has failed.

Seldom can a touchpad be repaired.  The normal solution is to replace the touchpad, which generally means replacing the whole front panel.  There are two types of touchpads: Membrane Switches and Capacitive Glass.

If your panel is glass, you have the latter kind.  This sophisticated design is actually sensitive to the conductance of human skin, which manipulates an electrical field when you hold your finger to the button.  And, there’s actually no button – you just touch the labelled area of the glass to input a command.  Capacitive touchpads contain their own electronic circuit boards which create signals and send them to the main control board for interpretation. These touchpads are really nice, but also quite delicate and expensive to replaced.

Membrane Switches are an older design consisting of a number of contacts arranged in a switching matrix, such that pressing any one button creates a unique short circuit between two of many contacts on a ribbon cable that connects to the control board.  The main control microprocessor interprets each short as a specific function.  Rarely, these can be repaired, but often replacement is the only option.

This company does carry its own line of replacement touchpads for select Whirlpool/KitchenAid Ovens, and is continuously expanding that inventory to more ovens as time goes on.  Yet, we also have the capability to modify your panel with a new touchpad that is functionally equivalent to your original in the event that your membrane switch fails and no replacements are available.

Bottom Line:

You now know the proper name for each aspect of an oven control system, and this company will help you regardless of which part has failed.

Obsolete Keypad/Touchpanel Unresponsive or Causing E1F2? Don’t Scrap Your Whirlpool/KitchenAid Oven

Are you having trouble finding a keypad for your Whirlpool/KitchenAid  oven?  Don’t worry, we have a new keypad solution.  This page discusses an option that will keep you from having to replacing an oven which can cost thousands of dollars.

For $300 or less, you can have functionality restored to your oven with a custom built keypad.  Most parts for Whirlpool/KitchenAid ovens are available for a very long time but the touch pad seems to be an exception to this.  The control panel is made of a sealed membrane switch that wears out over time.  Once this part fails, the oven can become unresponsive, beep randomly or throw error codes like E1F2. Applianceboards can custom build new, more robust, membrane switches that stick right onto your original panel.

This article refers to a specific problem we’ve been encountering with two different types of oven control boards – the relevant model and part numbers can be found at the end of the article.

These control boards can throw F1 error codes in response to a variety of failures.  Often, these error codes are the result of bad power supply or logic control circuits that can be repaired at FixYourBoard.com.  However, we have been finding that even after a control board is rebuilt and passes a full function test, it still throws F1 when reinstalled in the original oven.  How can this be?

Electronic Control Board Rebuilds

Electronic Control Board Rebuilds

It turns out that these control boards connect to the platinum temperature sensing rods through wire nuts.  The connection in the wire nut is going high resistance, which causes the control board to think the oven cavity is over temperature…resulting in an F1 overheat error code.  This connection seems especially susceptible to temperature change as well, so this problem is especially apparent as you start heating the oven.

So, if you’ve had your board rebuilt by FixYourBoard.com or recently got the board replaced, and you’ve replaced the temperature sensor, but you’re still getting an F1, inspect these wire nuts!  The easiest way to find the wire nuts will be to follow the wiring with your hand (make sure the breaker is off) from the temperature sensor (or from the board if you know which wires go to the sensor).

You will likely find that the wiring inside the nut has rusted/corroded.  We recommend you cut off the already exposed portions of the wire and strip some insulation off, allowing “fresh” wire to be reconnected in a new wire nut.

Remember to have all your control board needs handled at FixYourBoard.com!

Thermador Built-In Oven – Takes Too Long to Heat, Can’t Control Temperature, No Heat

Does your Thermador oven have temperature control problems caused by the control board?  The following post describes the behavior of a properly working control board in pre-heat.  This applies to the following model series: SCD27,  SCD30,  SCE30,  SCE70,  SC272,  SC301,  SC302,  SMWS7,  SMW27,  SM272,  SVD48,  S272T,  S301T and  S302T.  At www.FixYourBoard.com, we hear about problems such as the oven taking too long to heat, temperature fluctuations in the oven, oven is burning food or there is no heat at all.

First, the picture below shows the relevant connections  that should be measured to ensure that the elements are correctly turned on by the relays.  This picture is an example of part 492067 which is the power / relay board.  Its purpose is to provide power to the oven, turn on heating elements and fans, and communicate with the display board.

Relay Board and Noted Measurement Points

These ovens can be tricky to troubleshoot, but start with the following table which shows how the timer is controlling the heating elements and cooling fans.  Note that an AC voltmeter must be used to perform the following checks

Thermador Oven Control Board 486752 / 14-33-347 – Door Lock Sequence and Errors

Are you having door lock problems with your Thermador control board 486752 or 14-33-347,  487604 or 316080103.   At www.FixYourBoard.com, we get questions about the door lock operation for this controller.  This post addresses this by describing the sequence of events when the controller is programmed for a clean cycle.    We hope this information will help you  troubleshoot door lock issues with the following model numbers: RDDS30, RDDS30QW, RDDS30V, RDDS30VQB, RDDS30VQB, RDDS30VRS, RDDS30VRS, RDFS30, RDF30, RDF30QB, RDF30QW, RDF30RS, RDF30RS, RDSS30, RED30V, RED30VQB, RED30VQRS, RED30VQW, REF30, REF30QB, REF30QW, REF30RS, RES30, RES30QB, RES30RS, RES30W, RDDS30, RDDS30QW, RDDS30, RDDS30V, RDDS30VQB, RDDS30VRS, RDFS30, RDF30, RDF30QB, RDF30QW, RDF30RS, RDSS30, RED30V, RED30VQB, RED30VQRS, RED30VQW, REF30, REF30QB, REF30QW, REF30RS,  RES30,  RES30QB,  RES30RS,  RES30W.

State 1 -Clean Button Pressed and Time Set  (Door still unlocked)

Note that the blue display show that clean mode has been selected and the total time for the clean mode.  The state of the switches is shown in the diagram.  Pins 7 and 8 are shorted together with switch #1.  This is the un-locked state.

Thermador_486752_clean_start1

State 1 -Display As Soon as Clean Time is Programmed

State 2 – Automatic Door Locks are Running (One Second after State 1)

After a second in state 1, the following happens:

  1. The clean light comes on.
  2. Controller turns on the door lock motor.
  3. This state only last until motor releases switch 1 and pins 7 and 8 are no longer connected.

 

Thermador_486752_clean_start2

 

State 3 – Lock Motor Still Spinning and Switch #1 is Not Pressed anymore.

Pins 7, 8 and 9 are not connected and the motor is still spinning.

Note that the display shows the “locked” even though switch #2 is not pressed yet and door is not locked.  

 

Thermador_486752_clean_door_all_pins_open

 

State 4 – Lock Motor has Stopped Spinning Because Switch #2 shorted pin 7 to 9.  Oven has turned on the heating elements.

Note that the display now says “ON”.  This means that switch #2 was pressed by the lock motor which shorted pin 7 to 9.  The oven will now reach cleaning temperature.

 

Thermador_486752_clean_on

 

State 5 – Fault State.  If the controller does not sense the door lock on pins 7 and 9.

In this fault mode, the controller will beep and show door on the screen.

Thermador_486752_clean_door_error

Error State – Control did not receive the locked signal on pins 7 and 9.

Meaning of F1,F2,F3,F4,F5,F6,F7 codes for Garland/Manitowoc Ovens

Garland oven controllers are programmed to give meaningful information if they enter into a fault condition.  This applies to most Garland ovens such as models: UCO-G-5, ECO-G-10, ECO-G-20, ICO-G-10, ICO-G-20, IC0-E-10 , ICO-E-20, ECO-E-10, ECO-E-20,MP-ES, MP-ED, MP-GS, MP-GD, PaceSetter EC-I-36, EC-II-36, EC-I-42, EC-II-42, GC-I-36,GC-II-36,GC-I-42,GC-II-42, Trendsetter ovens TE3, TE4, TTE3, TTE4, TE3/4-x, TTE3/4-X, TE3/4ECH, TTE3/4ECH, TG2A, TG3,TG4,TTG3,TTG4, Sunfire SDG-1 and SGD-2, TE2A, KFC MCO-G-5K and others.

Many times the result of the F code troubleshooting points to the control board /Timer/ERC.  Don’t worry, they can be rebuilt even if the part is no longer available (NLA) or obsolete.  With www.garland.fixyourboard.com , you will never have to scrap a commercial oven due to failed electronics.

Some part numbers that throw F-codes are: 1517700, 1517701, 1517702, 1517703,1544800, 1517704,1517705, 1517706, 1517710 ,1544801, 1933801, 1933701,4521705,4521282, 4515873, 1025299, 1025204,1034199, 1244705, 1285601, 1025204, 1244704, 1285700, 1905701, 1025204,1244705, 1905601 among others.

Here is a summary of the fault codes and their meaning:

F1Relay Output is Enabled When Not Cooking. The cook relay is closed with no call for heat.
-Control should be rebuilt.

F2 Over Temperature Alarm. The control is sensing an oven temperature 50 degrees or more above the
maximum temperature of 500F
.
-Check the probe wiring and the probes resistance  and replace if faulty
-If probe is functional, rebuild control.

F3Open Probe Circuit. The control is sensing an open circuit at the probe input.

-Check the probe wiring and the probes resistance and replace if faulty.

-If probe is functional, rebuild control.

F4Shorted Probe Circuit. The control is sensing a short circuit at the probe.
-Check the probe wiring and the probes resistance and replace if faulty
-If probe is functional, rebuild control.

F5Relay outputs not enabled when cooking. The control is in cook mode and the heat relay is not closing.
-The control should be rebuilt

F6No 60Hz input. The control does not sense the input power.
-Check the power supply for noise
-If the supply is correct, rebuild control.

F7 EEPROM. The control has detected that the calculated EEPROM check sum is incorrect.

-Reset power to control and if problem persists, rebuild control.
