The dryer runs and drys fine but after it has gone trough a cycle and turned off , the timer keeps running through the next cycle option and sometimes turns back on. Is the the timer or another heat or mositure sensor?
Answer Hello Tom,
This issue would be caused by a bad timer 8566184. When the unit is in the off position. If you would want to check power to the timer. If you are getting 120vac between BU and WB then you have a bad timer. If you leave door open and still have power going betwen these connections then you would be looking for a short to ground. 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
The timer serves to convey current via the gas valve?
Answer Hi. Yes but..Use a volt/ohm meter part # TJMA-DM1 to assist you in your diagnostics. You need to measure the 120 vac to the ignitor part # 5303937186 first to see if the timer and the wires to the are ok. Then ohm the cold to see if it has between 50-400 ohms cold and it does not have a crack in the middle (opened). Dryer Gas Coils: Check the coils 5303931775 and see if they test good. You can test the coils using a multi-meter TJMA-DM1. The two prong coil will read 1,000-1,300 ohms, and the three prong coil will read 1,300-1,400 ohms across prongs 1&2, and 500-600 ohms across prongs 1&3. Beside the ignitor is a Flame sensor part # 5303281135 that has to be closed(0-ohms cold). It acts as a cycling thermostat to regulate the temperature. Make sure the door switch is shut, part # 5303281044. Does the unit run? The timer is no longer available. Thank You
