Questions & Answers

For Speedqueen Thermostat And Mounting Plate Kit (Part Number: OEM7216074)

1 Answer

Hello Trevor. It could be the coils. Check the coils 279834 and see if they test good. You can test the coils using a multi-meter MA-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. Test the coils after running the dryer for about 10 minutes. 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

Jeff for Model Number SDG2606AWW Maytag Gas Dryer

Our dryer no longer cycles when on the Auto Dry/ Regular setting, you start it at More dry and it will run and run and the dial never moves. The dryer will still work on the Timed dry setting, setting it at 60 minutes, it will cycle through and buzz when the time is up, but it is taking sometimes longer than 2 hours to dry a load of clothes. I cleaned out the entire vent system for the dryer, and tested the cycling thermostat, and it has continuity.

Hello Jeff, This sounds like you still have a ducting issue. You see, when the dryer is on automatic, it is using the moisture sensors. As long as the sensors pick up moisture, the timer will not get voltage to advance. If the duct is restricted, the sensors continue to sense moisture and the voltage is never sent to the timer motor. The reason for this is that the dryer drum is riding on felt seals. If there is too much back pressure from the exhaust duct, the heat, lint, and moisture will blow past the felt seals right back into the cabinet. When the unit is on timed dry, these sensors are not used, so it gets voltage and times out. The exhaust duct is the most important part of the dryer, even though it isn't part of the dryer. Most people think the heat dries the clothes. If this were true, you could dry the clothes in the microwave. Of course this would just result in hot wet clothes. The heat is an assistance to the air flow, to help to evaporate the moisture. The air flow then carries the moisture away. So, to get to the point, the shorter and straighter the exhaust duct is, the faster the clothes will dry. When you "check" the exhaust duct you're looking for clogged ducting, crimped ducting, and make sure it is as short and straight as possible. The only thing that will cause the timer not to advance in the automatic cycle when it will advance in the timed dry cycle is the duct. If you want to prove it to yourself the test the manufacturer tells technicians to do is to run the unit for five minutes with the duct pulled off in the automatic cycle. You will see the timer advance and this proves the problem to be after the dryer.

Hello Rad! It sounds as if the secondary coil has gone out on your dryer. The manufacture suggests to replace both coils at the same time. The coil kit is part number 279834. Thanks.

Hello Yun. The first thing you will need to check is the vent. Make sure it is not clogged or kinked. If it is clear, and the problem continues, you may need to replace the motor WP2200376. It sounds like it may be over heating. Hope this helps.

Hello Mike. Based on the information you provided, it sounds like the motor WP2200376 is bad and needs to be replaced. It is over heating and shuts down until it cools down. Hope this helps.

Danine, There are several posibilities, open thermostat, open valve coil, cracked igniter or inoperative flame sensor switch. All machinery can be fixxed, for less than a new unit in most cases. You will need to remove the front of the dryer, and observe the ignition process so we can have a direction to take. We'll be more than happy to walk you through the process. Thanks

Jeanne, I don't think a high limit thermostat will solve your issue. It sounds like you have a gas valve coil issue 279834 or regulating thermostat problem WPY61372 , but most likely the coils. Thanks and Good Luck

Billy, the limit thermostat 489P3 would be the issue if you can jump start it and the fire will stay on. You will also need to make sure you do not have a clogged blower or lint filter. Hope this helps!
