How do you test the thermostat that is by the motor? It has four wires that go to it.
Answer Hello Andy. The two large terminals on the thermostat control 31001088 should read closed and the two small terminals should have an ohms value around 4K. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
What are the other 2 parts to check for? I have new coils, checked thermo's, sensor,didn't check ignitor, it fires up. I hate to buy expensive gas valve because I don't know for sure if its the valve. Thank-you.
Answer Hi Marty. All thermal fuses should read closed, (0)-ohms. There is a sub la-1053 thermal fuse on the heater plenum, check this part # 53-1096. The flame sensor also reads closed. The igniter reads 50 -800 ohms closed , also if you see a hairline crack in the middle it may open under heat conditions. The cycling thermostat reads closed part # 31001088. Finally there is a coil kit you can use if you suspect they are open or open under fire, Part # 279834. Check and make sure you have 240 volts coming to the dryer. Check and make sure the unit is not set to Air Fluff. Also check the heater and thermal fuses and see if they are good. You can test these with a multi-meter parts you will need TJMA-DM1. They should read closed for continuity. Here is a link on how to use a multi-meter.

When testing flame sensor the ohm should read 0 on your meter?
Answer Hi Marty. Yes, the radiant sensor should read closed (0-ohms) when cold with at least 1 wire disconnected. It basically acts as the cycling thermostat for a gas dryer. If the gas starts then quickly goes out , this will be the one of three parts to look at as defective. Part # 338906. Thank You.
