The F155 error means CORRUPTED EEPROM

1. If the fault message is displayed at power-up, ignore it. Sometimes at power down, the control saves the current time but fails to calculate and write the checksum in its memory. At the following power-up, a fault occurs due to this failure.

2. If F155 appears when starting a cooking mode, it means that the cooking parameters in the control memory are corrupted. The display board will have to be replaced.

If the oven is on 350 degrees, in middle of cooking the oven suddenly goes to 418 degrees, the control panel was burning hot, the cooling down fan motor was still functioning and the oven door locked and opened locked and open. So now what is my problem?
Customer reply replied 2 years ago
If what your saying is correct, then why would my control panel overheat?
Appliance Technician: Joel Swenson,
 replied 2 years ago

beacause the cooking parameters in the control memory are corrupted and it is not regulating the proper temps, the information I provided came directly from the manufacturers service manual so it is correct information. I will be glad to upload the manual if you wish to look for yourself, thanks.

I saw the manual online also. Im looking for a professional who can help me diagnose the problem with this oven, not based solely on a manual.

sir I will opt out because I have told you what the issue is but you will not accept it. Maybe another tech can help you, thanks.
