Kenmore Wall Oven Fan 911.30465894

[srburk]

Hello all! I have a Kenmore gas wall oven, model 911.30465894. This morning while preheating, the oven became very silent. When I started to preheat the oven, the fan came on and then it stopped after a few minutes. The oven continued to increase the heat to the desired temperature. I proceeded with cooking and after a few minutes, the fan came on again. 

Oven heats and cooks fine. 
Fan sounds normal when it runs.
Fan stops running during cook time. Doesn't seem consistent with what it did prior to today. Prior to today, the fan would stay on until the oven cooled down after cooking.

Any recommendations would be greatly appreciated.

Check for a loose/chewed wire or burnt/fractured solder joint ... there should be a bi-metal thermostat in series with that fan motor also., but those are generally reliable.

Any mice running around at all?

No mice. Should I look for any loose/chewed wires or burnt/fractured solder joints in the within the control panel housing?

You need to look anywhere there is wiring. To do this you need to remove back cover panels. It can be dangerous make sure power is out and gas off.

It just sounds like a loose or bad connection... you have to pick a certain point to start from and follow the 120VAC that powers the fan... You can start from the wall outlet and make your way toward the control panel or vice/versa, but a intermittent operation like you are describing is always a Sherlock Holmes situation. If the tech sheet is still with the machine, a bit of research could be helpful in picking your "jumping-off" point... I wouldn't suspect say, the power cord lugs in this case because that would very likely be affecting more components than just the fan.

Your meter and  a voltage detector (hall effect indicator) are the tools for this job, especially if you can locate the fan circuit and get it to act up so you can see if the fan voltage is steady or if it is dropping out, and more importantly, where in the circuit is the interruption-
