The thermostate on my JennAir W188W oven appears to need replacement, as the oven temperature is no longer reliable. All parts still work to heat, operate convection fan, set electronic controls, but the thermostat appears to be unreliable in reading the actual oven temperature, and will fluctuate, meaning the degree by which the "read" temperature varies from actual temperature (measured by independent tool) is not consistent.

It's a pretty old wall oven, but has operated fine until within the past year, and I'd prefer to replace the thermostat rather than the entire oven, but the specific part needed appears to have been discontinued by Maytag, part AP364375.

Are there alternative replacement parts, or means to correct the issue with the current bad thermostat?

Thank you!
