For at least the past year we have had an issue with our Admiral oven heating properly. Prior to that, the stove was giving us an error code. But I don't remember what it was because it went away. It could have been related to the clock, I am not sure. Anyways, I performed OHMs tests on the temperature sensor and heating element and both checked out fine as far as specs. THat left the electronic control unit or some part of it as the likely suspect. I wanted to try to remove the unit to visually inspect it but am unable to remove the knobs on the front panel for timer, cook time etc. Is there any trick to doing that? I have pulled on them but I do not want to bust them off. However if I was to have to replace the ECU or any part of it I could not do so unless I am able to disconnect it from the front panel. THus the problem with the knobs. Any ideas?
