In Topic: Jenn Air (Maytag) W181 Electric Wall Oven- temp varies

Apparently, she was occasionally (over-)compensating on the temp setting due to its being too hot.

Hi Sensei,

Yes, I have those instructions and I don't know if the tech set them or not (thanks for the pdf). I will have to yank the oven out of the wall to see the thermostat on the back for the setting code. Though, I assume from my reading that this may improve the accuracy but not the range. The rocker (DIP?) switches can account for up a +/-30degF calibration adjustment.

And yes, 10% (35degF) would cover my appx range of +/-8% (27degF). That is kind of why I wondered if it is normal or not. Maybe my expectations are too high regarding thermal consistency in a (at the time) higher end residential wall oven. Thanks!

I was wondering.

1. Is there a generally accepted temperature range for residential and commercial ovens? Like +/-10%? I had been looking at new ovens, too, and one of the reviews complained about this very issue. Granted, my situation appears to be both range and median temperature issues.

2. Is there ever an adjustment for this range or is it a non-adjustable built-in function of the oven? Or, put another way, Is turning the oven's elements on and off controlled by the thermostat or by the control board?

Thanks.

1) multimeter with temperature reading abilities
2) just let the oven "warm up" for 20 or 30 minutes should do it ... to stabilize


I'll look for one of those multimeters (with high temp probes, I assume!) but my meter is just a std electrican's type meter. I may have to call in a service tech to do that. Arigatou.

Turns out that the original +/- 30 estimates were based more upon my daughters baking experience and not the dial thermometer. I noted during my cycle tests that the dial went up to 360 down to 350. There seemed to be a 5 or 6 minute lag compared to the digital thermometer. Since the two tests were pretty close, I imagine that a 3rd would not have been much different.

Regarding the service manual... I am not clear what it means. I don't have a high temp mercury thermometer and what is meant by a thermocouple? I get making sure that the ambient temps are zero'd out but on what? Also, I don't think the display shows when the elements are being powered or not ("unit cycles on and off"). Sorry.
