Need help with built-in oven on bake not maintaining temperature. No error codes, started last week maybe 2 weeks after she put it through self clean cycle. I didn't believe her but its true when I tested @ 275 heats up and says 275 after 15 minutes and is 275 when turn on & off right away.
Tested @ 350 heats up and says it is 350 after 15 minutes but when turn it off & on right away says it is really only 325.
Tested @ 400 heats up and says it is 400 after 15 minutes but when turn it off & on right away says it is really only 315
Broil seemed to bring temp up to 600 fine with red hot element.
In actual cooking when she new it was wrong it took turning the oven on & off several times to make it stay up at proper temp even though it says it maintains temp and you hear the ticking the temp would really seem to turn off so it took 1.5 hrs for 30 minute chicken casserole.
Visual on Bake element & Sensor ASM no burn damage. Haven't tested resistivity of either but need correct OHM reading for them if OK. By reading this forum it seems it may be one of the above cheaper parts or the more expensive Oven control erc111. Any suggestions on what/how I should try test further or if it likely which parts should I replace.
I checked twice and the above model # is correct on the plate but the website has no O between the B&A, weird?
Any assistance is greatly appreciated.
