7MMGDC400DW1 Maytag Dryer - Instructions

i was able to go on line with your company , find my dryer, order the part and had it the next day. fast , great , service

Pryed dryer top open and opened front door. . Unscrewed the 2 retaining screws. Pulled old switch from the wiring harness. Put new switch in place and replaced the retaining screws. Put new switch wire plug into the wiring harness. Before closing top, checked door switch function with dryer on. Dryer cut off when door open and when closed dryer started normally. . . Maint. Note instruction book should warn that letting door slam, which I did on occaision, broke the switch arm. Might save future problems.

PartSelect showed seven different possibilities why the dryer wouldn't heat. I removed the two screws to remove the bottom panel and turned the dryer on and noticed that the heating element that ignites the gas was working fine. This meant that it was not getting gas so it could be the gas valve or one of the two gas valve coils which are located on top of the gas valve. I borrowed my neighbor"s ohm meter and touched the two probes on the coils terminals to check for continuity and found that one of the coils read zero. I then took both of the coils out by removing two screws and tested each coil again. One coil read 500-850 and the other read zero. This meant that it was no good so I called for the part and received it in three days. I reassembled the parts and turned the dryer on and it fired up after a few seconds. It works as good as new. The part plus shipping was less than $30. My repairman would have charged me $150-$200. While the dryer was apart I gave it a good cleaning with a vacuum and a toothbrush in delicate areas. I also removed and cleaned the lint trap housing by removing two nuts. I didn't know much about gas dryers, but thanks to PartSelect I easily fixed it myself.

It was simple once I figured out what to do:). I removed the 2 screws on the top of the dryer... they were a bit hard to find. Even with the other descriptions on this site. I was removing things I didn't need to. The 2 screws you need to remove are under the LINT COLLECTOR LID. Remove those 2 screws & lift the lid... it will be tight at first. the front of the lid has 2 "catches" in the corners.

The hardest part was getting the door switch assembly to "unplug". We pried it off -- eventually -- & then simply plugged in the new one.

Saved me LOTS of money & was worth the 30 minutes - 1 hour of work.

As I said previously, once you realize how to get the lid up & manage to pry off the plug, that's all there is to it -- easy!

Save yourself time & money & do it yourself!

There was no problem with lint build-up within the dryer & the exhaust vent. I removed the gas cycling thermostat & thermal fuse from system & dryer still was not operating correctly. The radiant sensor & hi-limit thermostat both seemed to be operating correctly. That left either of the two coils as the culprits. I replaced both coils & the problem was corrected.

Timer wasn't working on the regular cycle so I replace it with a new one from partselect. It still wasn't working so I ordered and replace the cycling thermostat, the thermal fuse I also cleaned the vent and dryer it still didn't work so I read the diagram for the electrical and found that a coil for the gas valve is line with timer. I ordered the coils for the valves, replaced both valves and tested the dryer and it work just like when I first bought the appliance.

First unplug your dryer. Then, I removed the two screws on the lint trap leaving the lint trap in place--do not pull out the lint trap--only remove the two screws. Next, slide the top of the dryer slightly forward in order to release the top of the dryer. I did this with my hands. Once the top of the dryer is released, raise the top of the dryer and unplug the door switch assembly. Then, remove the two screws that hold the switch. These two screws were located on the front panel of my dryer and are visible when you open the dryer door. Remove the old switch and install the new switch by putting the two screws you previously took out from the old switch back in place and plug in the new switch. Lower the dryer top. Push the top back to lock in place. Line up the lint trap holes for the two screws that hold it in place and replace those screws. Plug your dryer back in and it should work properly. Very easy repair. We ordered our part one morning before noon, and it was here the next afternoon with regular shipping. GREAT SERVICE.

Determining the problem was the hardest part. With multiple parts (coils,thermostats...)possibly causing similar symptoms, I narrowed it down to the two coil valves.
Un plug the dryer. Remove two screws at the base of the front panel. Turn the front panel 180 degrees to avoid disconnecting the door switch. Gas valve with coils on top are on the right in front. Remove two screws in bracket holding coils, disconnect the wires, replace with new coils and reconnect wires. One coil has 2 terminals the other has 3 no chance of crossing the wires. I used an offset/right angle screw driver for one of the bracket screws due to close proximity to the drum. A stubby phillips head will work. You can check the burner operation with the front panel off as long as the door switch is still attached. Swing the front panel around and lift back into place securing with the two screws. Dryer works fine now.

After looking on the website for advice I walked throught the simple steps of disassembling the front, removing the drum, removed the back, disconnected the wire harness. Then removed the blower housing in the back. The blower, mounted on the back side of the motor was very tight. I used a pipe wrench wedged in place and help by my 10 year old Grand-daughter while I used an adjustable wrench to turn the shaft on the front of the motor. Spun the blower off, removed the two clips holding the motor. Then reversed the process when I received the new motor. Care should be taken to avoid damaging the blower fan if a lot of pressure is required.

couldn't get blower wheel off of the motor. really tight. rounded off the wheel's square hub while trying to hold it still as I turned the motor shaft out. No, I wasn't turning it the wrong way :) I ended up going to the back of the dryer and using the multimax to quickly cut the wheel away from the hub. I love that oscillating saw! Just for fun, I put the motor in a bench vise and got the wheel hub off (in pieces). VERY tight! Ordered new wheel, and the job was smooth sailing from there on. I am guessing that experienced repair people automatically order the motor and blower wheel at the same time(?) BTW both parts were perfect matches for the originals. Not surprised; this has always been my experience with partselect.com!

I removed the two screws holding the front panel to expose the lower works and verified the heating cycle failure. After a check of the vent system, checking the sensors for continuity and coils for resistance, I retired to the 'net for support. Accepting the general consensus that the most frequent, common and likely failure to be the coils, I rechecked them with the meter and found the two pronged coil to have significantly more resistance than the three prong coil. That was enough evidence to point to the coils. While I waited for the part to arrive, I replace the vent ducting. When the parts arrived I removed the two Phillips screws holding the coils, removed the old ones, installed the new ones, replaced the bracket, put the front cover back on and in less then ten minutes clothes where drying.

I read a fix-it article from another contributor and followed those instructions to the T. Pull out lint trap, remove the two screws. Slide the top cover towards the front and prop it up with a mop handle.
Unscrew two screws in the door switch (with the door open) - Oh, to keep from killing yourself unplug the dryer just in case. Take pliers and pull the plug apart. It will be right in front of you in the right corner at the top. Plug new switch into that plug, reinstall the switch by reinstalling the two screws you removed. Snap top back into place and reinstall the two screws at the lint trap. Oh, don't forget to clean the trap and slide it back into the unit. Now you have earned that beer.
Put tools away and proudly show your job off to the wife telling her how difficult it was.

1 Unplug power.
2. Remove the front of the unit by removing the two screws at the bottom of the front panel. Front dryer panel will swing out from the bottom and then the clips will release the top of the panel, careful not to disconnect the dryer door switch. ( can be unplugged to remove the front panel out of the way.)
3. Looking inside the unit on the right side you will see the gas value. On top of the gas unit you will see two small coils the coil closest to the burner has two leads on it. Remove the two screws to get to the coils, remove the medal plate, remove the connector then lift off the secondary coil. Replace and test. You can test unit with the front panel off. (be careful). If no heat, check that the Flat Style igniter is glowing. (ohm out both coils) before ordering parts. Intermittent heat problems. I replaced the secondary coil, it did ohm out o:k but it had swollen and was very tight on the shaft.

This was my first dryer repair, and it was so easy. Simply pull out the lint trap and unscrew the two screws that are exposed. They attach the top deck of the dryer to the drum.

Once it's unscrewed, pull forward while lifting the top of the dryer. The top is attached to the control assembly. They should both lift up, but you'll need something to prop it up like you would the hood of your car.

Next, use the pliers to pinch the connector so that you can separate the two parts of the connector.

Open the dryer door to gain access to the screws that hold the switch in place. Use your screwdriver to unscrew the switch.

Plug the new switch connector in, and close up the dryer.

Word of caution; there are sharp edges inside the dryer so be careful.

First I took the front of the dryer off then located the igniter. It only required removing two screws, removing old igniter, replacing with new igniter, and replacing the two screws.. While I was replacing the igniter I took the drum out and throughly cleaned the inside. Lucky me, I found 85 cents on the floor of the dryer. I am 65yrs old, married and mother of two.
This was easy to do and sure saved money. I reccommend others try to do repairs for themselves and using PartSelect was less expensive too.
