Glasstop stove F1 & F3, beeping, beeping.........
I have an older Maytag glasstop stove (MES5770AAB).
The stove top burners work fine. And the oven works some of the time. But if the top burners are used, and then the stove, sometimes it gets up to temperature, then flashes F1 or F3, and beeps until it cools off.
I've changed out the oven temperature sensor with a new one, and its still happening.
At first I thought it was the connection wires- there are two, and because the plastic connectors didn't fit (I stupidly missed the adapter piece in the bottom of the box), I had used wire caps and screwed on the two contact points.
AI (Google Gemini) went on about the wire caps not being true heat compatible wirecaps. So I went back and stripped the wires clean, and connected them with ceramic oven wirecaps, rated for 600'F. Then for good measure, I wrapped the caps in high temperature silicone tape. I then made sure none of the wires behind the oven were touching the back metal panel.
Tried the stove with the back off. IT WORKED.
Tried the top burners, then the stove. IT WORKED.
Put the back panel back on, pushed it back in the corner, and ran the stove one more time
F1, F3, beeping still.
Unplugged, plugged it back in. Ran the stove.
F1, F3, beeping again after it gets up to temperature.
I'm defeated. What in the world could this be? It seems a simple thing but I can't figure it out for anything. Has anyone seen this happen before.
