7MMGE7973TW1 Dryer - Instructions

Our dryer would not heat and it seemed that no gas was coming from the regulator. The igniter was working fine but the burner never turned on. To check the problem, i followed the instructions to remove all body panels until I had access to the burner assembly. I dismantled both gas valve coils and tested each one for open or closed circuit using my multi-tester. I found that the three terminal gas valve coil was an open circuit and was not functioning so I ordered a new one from PartSelect and within just a couple days, had the drier back up and functioning. I also replaced the igniter due to a malfunctioning igniter that has been changed by the manufacture. I must say that PartSelect has the fastest shipping I have ever seen. One part I ordered was at my door in less than 24 hours and I only paid standard shipping...un real! OUTSTANDING....5 STAR SERVICE

I tried to follow directions followed by others on this site after diagnosing the problem via suggestions provided by users. I have a Whirlpool Duet dryer from 2002. We've had problems since moving about 3 years ago. I removed the front panel (lower) by unscrewing the two bottom screws (1/4" sheet metal screws). Then I took out the lint screen and the metal tube/contraption immediately beneath to get access to the area where thermistor is located. See the drawing/chart to help you locate this. It's really easier than it seems. Make sure you have the chart/drawing for your model - it makes difference! The thermistor came out pretty easily with a nutdriver that has a swivel offset shaft. Ask your hardware store tool dept. about that one. Put everything back in reverse order of course and test either with/without the front panel re-attached. In my case it fixed at least part of the problem. I was able to get clothes almost dry with most settings but I have yet to install the moisture sensor to see if that helps in addition to the internal-bias thermistor. I am the kind of person that does one thing at a time so at least I now know the thermistor was bad. Good luck and hang in there with your own repair. It's a lot cheaper even if it takes you longer to do than a pro.

If you were to do the Belt Replacement only, here is the quick synopsis:
1. Unplug dryer;
2a. Open lint door on top of dryer and remove the two phillips head screws that hold the lint bay to the metal dryer top;
2b. Next remove the two brakets holding the metal top to the dryer back (one screw on each bracket);
3. Use a flat-blade screw driver to pry off the top of the dryer (leaving the timer and start button area attached);
4. Lift off top and push back to expose just enough area so you can get to the two screws holding the dryer sides to the dryer front;
5. Unplug door switch;
6. Unscrew screws from #4;
7. With door open, lift dryer front (only about an inch) and then pry bottom of dryer front from dryer sides. The bottom of the dryer front is not screwed, just siting on Front Panel Clips;
8. Once the front is off the dryer, simply remove the belt and install the new one. Please note that while you are in here, you may want to inspect the rear drum seal and replace if it is worn to the point where metal is rubbing on metal. This is also a good time to clean out dust from inside this cavity to help extend the life of the bearings on the rollers and prevent dust from accumulating and gunking up the motor, etc.
9. Re-assemble tin the opposite order.
If you have any mechanical sense at all and you don't know anything about dryers, you will be surprised at the simplicity of the dryer.

The dryer motor quit working. Learned, if you are changing one that is old, get the blower wheel fan too! I could not break mine loose from the motor shaft, and had to bust it off.

To un-screw the blower wheel fan from the motor shaft: from the front of the dryer, grab the plastic fan on the back of the motor with an adjustable wrench, and the motor shaft on the front of the motor with vice grips. Turn the motor shaft CLOCKWISE holding the fan still to un-screw the fan. If you have to remove the pulley, grab the shaft and turn the pulley COUNTERCLOCKWISE with a wrench.

Just make sure to pay attention to the orientation of the new motor in the instructions. If you match the old motor, it will not fit. It is all spelled out in the directions.

I removed the front panel of the dryer by removing the 2 screw that secure it at the bottom and pulling upward to disconnect the cover at the top. I then removed the two screws that hold the metal cover that secures the 2 elements in place. I disconnected the wire plugs from the 2 elements, removed the 2 elements and replaced them with the new parts making sure to place them in the same positions as before. I then replaced the housing cover and tightened the screws. Then I replaced the front cover of the dryer.

Initially we thought the problem was the igniter, so we ordered an igniter kit. Installed it but was unsuccessful. We then went on the websight and read further, about 50% of dryers with no heat but working had a problem with the thermal fuse.So we ordered the thermal fuse installed it, which was very easy, and success. Once the problem was diagnosed properly it was fast and easy. Recommend looking at the statistics for specific problem.

After replacing all the other fuses and sensors I finally replaced the Radiant Flame Sensor and it is working perfectly.

After replacing the other parts and the heat still not coming on I read somewhere that the Radiant Flame Sensor is a normal closed circuit and when I checked with a meter it was open. I would have saved a lot of time and money if I had read that earlier.

After unplugging and removing the back cover from the dryer, locate the push button switch. Slide putty knife around outer cover to unhook catch. Replace with new push button switch. My dryer is still not working, but this was a simple replacement.

Removed back cover, removed broken switch, replaced with new switch, replaced back cover, told wife her dryer was fixed.

First, I watched a utube video of replacing the dryer belt. Then I went to Sears Hardware and couldn't find a part. Then I ordered the parts for my favorite online repair parts source - partselect.com. I had the part in one day! We did exactly what the video showed and also replaced the two wheels that looked like roller blade wheels. Piece of cake. Saved a $75 repair call plus whatever the parts would have been and spent about 20 minutes doing it. Back in business. Great for a 12 year old dryer! Buy the dryer kit!

I looked for squeaky dryer within parts select and went with the 80%. I received the Maintenance Kit, replaced two rollers and it works like new. Amazing since this is the first time I have ever opened a dryer. The instruction sheet and parts were all I needed.

installed the new dryer lint screen, it fit perfectly
and is now in operation.

With the dryer taken apart to replace the broken belt it was obvious that the lint seals had not been working properly due to the excessive amount of lint covering all of the inside surfaces of the dryer. The belt idler pully had also moved from its normal mounting position and was laying at the bottom of the dryer. Because the lint had covered the bottom before the belt broke it was obvious to determine where the idler pully attached to the bottom.

Before cleaning I marked the exact location where the idler pully mounted to the bottom of the dryer.

While waiting for the replacement parts to be delivered a vacuum cleaner was used to remove lint from the inside surfaces of the dryer as well as the old fragments of the lint trap housing seals were removed and surfaces where the new seals would attach were cleaned.

Assembling the dryer with the new belt was a challenge due to the lack of support for the drum while getting the new belt in place, lined up properly, threaded through the idler pully and attached to the motor drive shaft. This is how I installed the new belt:

I used a piece of wood wider than the sides of the dryer, drilled holes that allowed for a piece of cloths line rope to be looped through and used to support the door opening end of the drum.

The drum was set on the seal and rollers at the back of the dryer.

The temporary wood /rope hanger was placed at the front end of the dryer resting on the sides with the top of the dryer raised.

The rope was adjusted until the drum rested on the back rollers and the rope like it would be positioned normally.

The new belt was then gently installed under the temporary support rope and around the drum.

The new belt had many kinks from shipping and was difficult to align with the location on the drum where it needs to ride so small strips of tape were temporarily used to hold the new belt in position until it could be fed through the idler pully and on to the drive shaft.

Several small pieces of a cardboard box were used to shim under the idler pully to hold it in its proper location as well as to make the belt attachment to the drive shaft easier.

With the belt attached, the temporary cardboard shims were removed from under the idler pully.

The front of the dryer was attached .

The temporary board and rope hanger was removed.

The tape that had been placed over the new belt to hold it in proper alignment was removed as the drum was rotated slowly by hand to ensure that all tape was removed prior to closing the top of the dryer.

The seals as well as the remainder of the dryer assembly was completed without any problems.

The dryer ran well for its initial trial spin and has dried several loads of laundry since.

Great parts and support Thankyou

I just inserted the door catch, which by the way fit in perfectly. Thanks. Took 5 seconds to repair.

Removed the back of the dryer panel and replaced the relay that was not working. The dryer then worked for the next weekend of laundry then the dryer did the same thing at the end of our chores. I then pulled the panel back off and found the control pane (eend heat control) was burned up. I ended up buying a new dryer , a different brand of course, the next weekend. I want to thank your site for all the help. I otherwise would have spent much more on a repairman on items I did/could do myself.
