I bought this range used/liquidated, so no warranty that I'm aware of... I think I will call GE and inquire anyway. The worst they can tell me is no!
When I had the range out last weekend, I did not see any wiring diagram, but it may have been removed since the unit didn't have any original packaging when I bought it. When this problem started, I arrived at our cabin to find the clocks flashing and the oven display dead. My guess is that there was a power loss along with the the brownout and surge that inevitably accompanies it and wreaks havoc on electronics. I have since started to shut off breakers to everything that doesn't need power while we're not there because I really don't want to keep having similar issues.
Wouldn't the safety thermostat kill power to the cooktop as well?
I counted what I think are 4 low voltage transformers on the front of the board and 2 on the back. They're rectangular, labelled 22/25V, and all next to or feeding capacitors. I'll check them, but have no idea where I could find replacements... the board is made in China by Sanyo.
If I order a board and don't need it because I'm able to fix the current one, can I return the new board?
