Home Diagnostics for Your RDD, RDS, RDF, RED, REF, RES Thermador Oven Range Cooktop Stove

Is your Thermador oven throwing error codes, not heating to set temp., or malfunctioning in other ways?

You may need to have your control board repaired, but the problem could also be failing hardware in your oven.

Luckily, these boards have a built-in diagnostic feature that can tell you where the problem is.  To enter the diagnostic mode, you need to have the breaker to your oven shut off.  Hold down the “Stop Time” button (center button) and have a friend turn the breaker back on.  Until the button is depressed, the control will beep and show the microprocessor ID in blue digits and dashes in red digits.  Once “Stop Time” is depressed, the control will stop beeping and show dashes in both the blue and red digits.

14-33-347,486752

Display shows Microprocessor ID and dashes when you enter Diagnostics Mode.

From here, you can test all the various functions of the oven control.

Holding any of the cooking buttons (Convection, Bake, or Broil) will energize that element relay while the button is held in, and the display will show “ON”.  You should hear a *click* whenever the relay turns on or off.  Depressing the button turns the relay off.

Holding the Clock button will energize the door latch relay and illuminate all display segments.

Holding the Stop Time button will cause the board to beep and show the same screen as when you entered Diagnostics: 4 digit Microprocessor ID and dashes.

Holding the Cook Time Button will show the  EEPROM checksum in blue digits and the current oven sensor temperature in red.

Holding the Timer button will cause the control board to beep.

Holding the Clean button will reveal the current state of the door latch.  Depending on which revision of the control board you have, there are 4 possible conditions, represented by either numbers 0-3 or 4-7…

  • 0 or 4: Latch in transition between states. Unlock Switch 1 and Lock Switch 2 are both open.
  • 1 or 5: Fully Latched (door closed). Unlock Switch 1 is open and Lock Switch 2 is closed.
  • 2 or 6: Fully Unlatched. Unlock Switch 1 is closed and Lock Switch 2 is open.
  • 3 or 7: Invalid Latch State. Unlock Switch 1 and Lock Switch 2 are both closed.

Pressing Cancel/Clear/Off will exit the Diagnostic Mode.

 

 

So, this is a powerful troubleshooting tool.  For example, if your oven isn’t heating properly, use diagnostic mode to figure out which element isn’t heating.  Hold Bake, you should hear the Bake relay click, and the Bake element (bottom) should heat as long as the button is held in.  If you hear the click, but there’s no heat, check the wiring to the element and the element itself (hardware specs below).  If the hardware is good, then the control board needs to be sent in for repair.  Even if the relay clicks, it can still have bad contacts.

Or, perhaps the oven isn’t heating properly because there is a failure in the temperature sensing circuit.  Hold the Cook Time button to reveal the oven sensor temperature.  If the oven has been idling at room temperature, then the red digits should display something around “070” (70 degrees).  Anything drastically different than this means there is a definite problem.  Check the wiring to the oven sensor and the sensor itself.  If the hardware is good, then the control board needs to be sent in for repair.

There are is a variety of possible failures for these ovens.  Using the diagnostics mode can help you find which circuit is faulty, and then you can use the table below to determine whether it’s a hardware problem or control board problem.

 

DANGER HIGH VOLTAGE!  You do not need power to the oven to make these measurements. Please cut the breaker.

HARDWARE TERMINALS RESULT
Bake Element E6** 18-26 Ω
Broil Element E7** 12-20 Ω
Convection Motor E2 to E8 55-80 Ω
Latch Motor E2 to E5 835-870 Ω
Temperature Sensor J1: pins 3 to 5 ~1080 Ω at Room Temp

**NOTE: The motors and sensor checks test the hardware and relevant wiring simultaneously.  There’s no good way to test the heating elements and their wiring at the same time.  Check the resistance of the elements at the ends of the element, and then individually inspect the wires from the ends of the elements.

 

This troubleshooting guide applies to the following Part and Model numbers…

P/N: 14-33-347, 35-00-571, 35-00-751, 486752, 487604

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.
