Have gas dryer. No heat changed ignitor, coils have gas. How do I test thermostat?

Answer Hello Ed,
To test the thermostats you will need to do a continuity check. The thermostats and thermal fuses should have continuity and if they do not then they would need to be replaced. 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
Could this cause my dryer to not want to heat up? I change the gas coil valve and the ignitor already. I missed this thermostat and the top one when I did my multi meter. The top read fine but this one doesn't read anything at all.Thanks

Answer Hi Mike. Do you have access to a clamp on amp meter ? If so then clamp it on the red wire going to the igniter (or one of the 2 wires). Then tape the door sw. shut and see if the igniter glows as it pulls between 3.2-3.6 amps. It also should read cold at 50-800 ohms, not open this is part # 5303937186. The thermostats should all read closed part # 131539400 the inner 2 wires (or the 1-inner -to-outer terminal) should read a resistance reading for a heater resister is 50k ohms (the 2- blue wires connect). Thank You.

Answer Mike, Yes, an open thermostat circuit, would keep the dryer from heating. The thermostat should have a "closed" circuit at room temperature across the two "lower" terminals(pink and orange) and 7 K miliohms across the "upper" terminals (pink and blue) with the wires disconnected. Thanks and Good Luck
