I'm trying to help a friend repair his oven he didn't mention any big blow ups or the oven lighting up but he does have the EOC not powering on problem like I've read on many posts on this forum which point to replacing the EOC but since neither is loose on change I was wondering how deep we can go in troubleshooting. I can't find the post but someone mentioned that where they bought their new EOC they gave him/her back $25 for the old EOC. I assume they must not give out $25 just for kicks and fix them somehow, faulty condensator, resistor, etc.. which they replace on the circuit board? But which one is the problem child if it is the EOC.

I checked the sensor resistance out and it seemed ok at 1090.

The relay, well I think it's the relay, ( black box not on the control panel itself but right beside it on the EOC steel bracket ) clicks when buttons on the EOC like bake are pressed and then a few seconds later you hear it click again like it's not staying closed. If you press bake it clicks and if you press cancel right after that first click it clicks right away. Would that mean that the EOC ( control panel ) has power to it? I haven't figured out what wires / contacts to test out to make sure power is actually going to the EOC.

Could anyone point me in the right direction to make sure and test that the EOC does indeed have power coming to it on the right wires / contacts with the above links I've supplied. Visual look on the EOC does not point to any burnt out parts. Would there be a fuse anywhere?

I appreciate any help and thank you for this forum, especially the humor factor you've put into this dear Sensei and Mrs. Sensei, was just listening to a few podcasts, lol.

I'm wondering if I should create a new topic for this since the friend didn't get the " close encounters of the third kind " light syndrome.

Arigato.

Well now I really shot the EOC while testing for power ( shorted, transistor blew, visible black smoke on the circuit board ).

Now I'm wondering if anyone here has ever bypassed the EOC ( basically eliminated it ) and installed a simple oven dial to save money by taking it from an old oven? I understand the convection function and self clean wouldn't work but all he really needs is to oven to do basic cooking. Esthetics is not important.

Thank you.

Even if you did try to make it into a manual, non-digital, oven, you would still have to buy a thermostat. I don't think the board, EOC, would be that much more expensive than the stuff you would have to buy to get rid of the EOC.

Wasn't thinking of buying but taking it off an old one as mentionned on the last post. You're right the new ones are as expensive as a new EOC but this would elimate any future EOC issues even if the friend would have to buy one.

So basically you're not saying this is impossible if we find an old working thermostat and probe. We just have to figure out the wiring on what to plug from the EOC to where on the thermostat for it not to blow up.

I don't see why this wouldn't work and am surprised I haven't found any subjects on this with all the multiple EOCs out of commission on the same units from posts I've read. I'm sure merc thermostats don't go out as much as EOCs.

Thanks for your help.
