Napoleon -- How much for that oven?

If it is that old, the best option for sure is to send the control board in to be repaired.

Make a note of your connections prior to pulling the board (black-L1, red - L2, Blue-Broil, Yellow-bake, orange-convec, etc)

Then contact core centric. Core centric PCB control board repair

They warranty the repair, and many times they fix issues that are known to fail in boards even if they haven't failed. The repair is a flat rate per board too.

I use them a lot for old boards. Likely you get the repair and the problem never returns.

That said. A great thing to do is to get a multimeter or a continuity tester and test every wire that isn't green or white and make sure nothing is in continuity with the oven chassis (ground) (other than white or green wires or a mostly white wire)

A short in the oven would fry a new board, but 99.9% of the time trips the breakers or produces heat, so this isn't common if there is no tripped breaker or heat when off.



Wall ovens, anything but GE.

I actually like Whirlpool wall ovens, frigidaire seem to be flakey after a while. High end, Dacor or Viking, lower end LG or Whirlpool.

I have a used double Viking set I'm about to sell
