Oven ignites with good flame for a few seconds then goes out and comes back on with small flame.
Answer Hello Joe. That sounds like a pressure regulator or gas valve issue, if the flame is to small to heat properly.
Oven Op Panel shows correct temp, but actual temp is much lower. Checked resistance on temp sensor, it was 1107 ohms at ~70 degrees. It appears correct. What else could be wrong?
The oven sensor should be at 1090 ohms plus or minus 10 percent at 77 degrees. If the sensor is checking ok then you would want to check the wiring from the sensor to the control. If wiring checks ok then you will want to check the elements to ensure that they are getting proper power and check to make sure that neither of the elements are bad.
