Thermador C302U error code

We recently came home from vacation and found our oven displaying the code "CAL". The command keys are not functioning, the clock works fine. I reset the breaker at the electrical box, the error code vanished but control pad is still not responsive. I was told by customer service at Thermador that "CAL" referred to a bad connection to the display board. Does this sound right? Also wondering if and/or where I can possibly get a schematic of our oven.

Thanks,

From my experience when there is a power outage, This is likely to have wiped out the control board on your oven. I see it all the time after storms. If a storm comes through, I get a ton of phone calls about control boards not working anymore or doing crazy stuff. If resetting the breaker has shed no light on your situation. I would recommend replacing the main control.

Also when you get this fixed, plug the stove into a surge protector of some sort. This will decrease the chances of a power outage doing damage to the oven control.

Hope that helps........

I have a Thermador Model C302U wall oven the fan on the uppper oven starts and then stops and I get the F34 code I am thinking to replace the motor but I want to know if there are other things I should...


When that fan starts up the air pushes against an air switch and that tells the board the fan is blowing. The stove uses a DAC system that relies on switchs to confirm the operations of the fan. the DAC control uses signal voltage to detect switch function. The air switches must physically close by air movement from the cooling blowers before the oven proceeds into a bake or broil mode. Reason being f the cooling motor does not function and the oven goes into a bake or broil mode, the oven will overheat and could damage the fancy smancy over engineered piece of garbage electronic components. My opinion. This is not for the DIY unless you are a TV repairman.

CODE F64 WHEN TRYING TO USE THE BOTTOM OVEN.


Hi, i found out from Thermador customer service that error code F64 means that the lower fan switch (located inside the bottom trim on the right side) is not being detected as closed. In my case, this was because the header (P4) on the Display panel had broken loose from the PC board and was no longer making contact. P4 is where the lower fan switch wires connect to the control boards (actually the display panel).

Oven door wont open code f53 thermador how can i get it open food is in it


Hello,.

Welcome to FixYa.

The "F53" error code on your Thermador "C" series ovens indicates a upper door lock fault, makes sense since that is the issue you described.

Whether there is actually a fault with the lock remains to be seen. Here is what I`d suggest you try...

Locate the service panel for your oven ( should be an isolated 40amp breaker ) and turn it off for a few moments and turn it back on.

This will initiate the start-up sequence which activates and checks the controls and lock assembly, hopefully resetting it to the "open" position and subsequently eliminating the error code.

Let me know how that works or if you require further assistance.

Thanks for choosing FixYa and good luck.

Regards,

Macmarkus :)

We had a power outage and when the electricity was restored the oven is displaying an F1 and F7 code and is beeping the alarm, how do i stop this?


Hello, the F1 error code means internal logic failure (monitoring function) it sounds alarm and inhibit cook mode You can fix it by replacing the electronic range control (ERC)

F7 error code means the function key shorted for over 16 seconds, check for something pressing a key or preventing normal release of the key. You can fix it by replacing the electronic range control (ERC) if other component check normal.

Thanks

Thermador over/microwave/heating drawer model SMW272YP Bake bottom element will not heat up. I have replaced the element. The display pannel has been replaced in the past, but still keep having the same...


I just found out my baking oven doesn't work and I hear the fan for the convection roast, but no heat. I had the appliance man out and he said that I need a relay board! Big bucks and they don't make this model anymore. Moreover, the microwave and warming drawer work fine. This is ridiculous!
