I have a SR379 whirlpool gas range. The burners and broiler work fine. During the preheat cycle, the gas clicks on and off never reaching the desired temp. This problem occurred after cleaning the oven then turning the gas off for a few months. After running the burners on top for a few minutes (in case there was air in the line) the preheat cycle worked, but the problem reoccurred again later that day. The sensor on top is clean without residue. I just can't pinpoint the issue. Any suggestions?

Re: unable to preheat
You need to replace the temp. sensor. It's not reading correctly. These occasionally go when you use the self clean as the range gets up as high as 900 degrees. Replace it and it will solve the problem

sounds like an issue with the spark module, altough that module tends to be really relliable.i would try removing pawer to te unit. checking the outlet for proper grounding,and replugging unit see if that works for you
Very well could be. I'm assuming the bake burner is the problem, right? Does the igniter glow at all? If it is glowing, but the burner does not light, is it usually a symptom of an igniter that has become weak. If it does not draw enough current the gas valve will not open and the burner will not light. This is a safety feature to prevent free flowing gas without ignition. If the broil burner is functioning properly, then more than likely the gas valve and regulator are working fine. In most ranges both burners are fed from the same source. You could try swapping igniters between the broil and bake burners to prove the theory. Or, you could just replace the igniter all together. Current readings are as follows:
Round shaped glow igniter: 2.7 to 3.2 amps
Square shaped glow igniter: 3.2 to 3.7 amps
If you can give me the exact model number off your range (usually located around the oven door or on the back of the range) I can give you the correct part number you will need. Most appliance repair stores carry the igniter. I hope this helps you.
