Oven wouldn't stay heated, now won't heat up at all
Model Number: RST387UWW Brand:
More than 10 years
Propane Gas Oven would not heat up consistently. It would heat up to desired temp, then start losing heat (although display still read desired temp). Replaced the gas valve, part # AP4279176. Worked fine for a few days, then started losing heat again. Then oven stopped heating up altogether. Burners still work just fine. Any suggestions before I call a repairman to find out whether it should be fixed or replaced?
