Hi all:

This is in regards to my Whirlpool SF368LEPB0 oven. Every so often the oven fails to keep the temp at the proper level. I'll turn on the oven, let it preheat, toss in what I'm cooking then let it cook my dinner. Once in a while after about 20 mins or so, the oven will not maintain the temp I've set. Basically shuts off.

I've checked the sensor and I'm getting 1099 ohms. The gas valve reads 216 on the broiler side, 217 on the oven.

What next? Is it possible that the valve is acting intermittent? Or could it be on of the electronic controls?

Thanks in advance.

Gunnar

Intermittent problems are the most difficult to diagnose because you need to catch it when it's not working. Here's the pin-outs for the DSI board when in bake mode. Make sure you read the same voltage at the DSI valve that you have on the DSI board:

In some situations the oven sensor can test good but open or short at higher temperatures.
