Originaly flame would not light at all. I found high limit sensor tripped, reset switch and flame would light and then go out in 15-20 seconds. Cleaned out vent system and replaced high limit sensor worked for three days and then found switch tripped again. Reset and tested several times but now flame is shutting down with out sensor reset button tripping. I just let it set for 5-10 min and flame lights again. I bypassed the thermostat switch and flame remains lit. The sensor has continuity but am wondering if the test indicates that sensor opens prematurely? Does this rule out a gas valve problem? Is it fairly common for sensor to test fine but open prematurely?
ANSWER Hello Jeff. Test the sensor and see if it opens early. If so, you will need to replace the sensor. If not, you may have and issue with the pressure regulator on the unit or the gas valve could have bad coils on it. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
