GE dbl, oven ZET2S0L1SS runaway temps both ovens

4 posts in this topic

Both ovens seem to be heating all the time going way over set temps while display reads 100º.

Put into diagnostic mode and got error F cd 95 which is not listed in manual or mini-manual. Ran manual test mode on all functions--everything worked properly although I couldn't distinguish hi from lo fan speeds in lower oven. Although, I don't see how that is pertinent to this issue.

Also checked both oven sensors even though it is highly unlikely they both went out simultaneously. They checked out at 1090 ohms at room temp--okay. My guess is the ERC is the cause. What do you guys think?

check connector cn7. It connects to both upper and lower temp encoder boards as well as relays for both upper ovens. That's the only thing I see other than the ERC that can affect both ovens equally without there being a double failur. ie both encoder or both relays failing.

I agree.  Both ovens have their own relay board and, while it's possible both boards are bad, it's very unlikely.  The specific components that would have to go bad on each relay board to create the conditions you're seeing are both the bake and broil relays on BOTH boards.  The chances of that happening are about the same as winning the lottery.  

 

The logic board is common to both ovens and it's possible it got its little silicon brains scrambled by a power surge.  Part number: AP3949476
