Dacor CPO230WO and CP0130C Cooling Fan Problem and F1,F2,F3,F4 error codes

At www.FixYourBoard.com, we see controllers come in for Dacor model numbers CPO230W, CP0130C.  These models use the following control boards control that can be rebuild quickly and reliably – 82810, 82812, 82811, 82837, 82875, 82874.

The most common symptoms for these boards are F1,F2,F3,F4,F5,F6 error codes.  Sometimes they throw F6 codes.

For these models, when the cooling fan does not operate, it is not due to the control boards.   The following diagram illustrates this.  The red line annotates how the fan is turned on using the DLB relays to supply L1 to the fan through the thermal switch.  This means that if the oven is heating, the DLB is working and the problem must be with the thermal switch or cooling blower itself.  Note that when the cooling fan does not work, the oven can have a difficult time controlling temperature.  It is not uncommon for the oven to burn the top of the food while baking if the fan is not working properly.Dacor  Wiring Diagram for CP0230
