Built-in Oven not heating up?

[shaitan00]

A few weeks ago my Built-in Oven stopped working, I would set the temperature (so you see the target temp in red and bake <on>) and it would sit there for 10-30 seconds then go back to the idle (clock) state. I tried the various modes but the best example is convection where I set it and the fan starts and 10-30 seconds later it just turns off and the screen returns to the clock. As far as I can tell the elements are not working (don't feel hot to the touch) but it doesn't stay on long, there are no errors messages or any other indication, it acts as-if I pressed the CLEAR button essentially.

 

I tried the breakers (both at the power box and the ones near the unit) and it didn't work, so I left it there for a week. After I tried it (by simply flipping the breakers) again and miraculously it worked ... for 3 days ... since then I have been unable to get it to work again ... same as the original problem.

 

The unit is a built-in over/convection, on the unit it says (GE profile) and the user manual has the following on the footer of the cover page:

  300A500P34

  WB60M778

The unit came with my home and I would assume it is at least 5-10 years old.

 

I would like to try and exhaust my options (DIY) before calling a repair guy (going to cost more than the worth of the oven) or buying a new one (this one is too small so I was hoping to buy a bigger one when I renovate my kitchen - in like 100 years :)).

 

Any ideas, tests, recommendations would be greatly appreciated.

Thanks,

The numbers you posted are not model numbers. Open the oven door and there should be a metal tag with a model number(usually on the top part of the frame) or, if there is a bottom drawer, there should be a tag(either on the left or right side) that has a model number. And......knowing if it's gas or electric would also help a great deal.....anyway, that's why giving a proper model number is important......it gives us techs a better opportunity to give you an accurate diagnosis.......or at least give it our best guess as to solving your problem.

Hey, one quick question.......what part of Canada?? Ontario or a little west of there? Just curious......and a gut feeling.....

Anyway.......post a correct model number and we'll do our best to help you out bro......

Typical symptoms of a bad main control board - not at all an uncommon problem in older GE ovens/ranges.

Good chance control board may be no longer available - there are re-builders that can repair them.

@BrewHobbyTech

I can't find any additional information on the unit, the user manual says the MODEL should be written inside as well but there is nothing there - looks like it was removed (or something) - the oven is ELECTRIC and I am in Quebec

I was hoping for anything BUT that ....
