7MMGDC400DW0 Maytag Dryer - Instructions

1. Shut off gas and disconnected dryer.
2. Opened cabinet. Easy sheet metal screws and fairly obvious how everything goes together. NB: You'll need a block (or a helper to hold things while you run to look for one) to hold the drum while removing the front.
3. The motor is connected with a single harness, so wiring is a snap.
4. Removing the blower wheel from the back was hard. I braced the motor shaft and turned with all the leverage I could muster, but it was stuck. Plan B: Recip saw to cut the shaft. Motor comes out one side and the fan comes out the other.
5. The fan, of course, was unusable because there was still a piece of motor shaft stuck in the thread. This is why I had to spring for a new wheel.
6. Put everything back together and receive wife's adoring praise...

Opened front panel .Tested both coils on gas valve.
Found no continuity on one of the coils. Replaced coil,
dryer works like new.

Took out two front Panel screws and removed the panel. Removed Gas solenoid coil holding bracket by removing two phillips head screws. Disconnected the coil leads. and removed the coils. Connected the new coils to the leads and set in place. Replaced the holding bracket and the two screws. Replaced the front cover and the two front cover screws. Piece of Cake!

Opened the lid and removed screws hollding switch to cabinet. Had to use magnifying glass to find locking mechanism on the electrical harness. Used small bladed screwdiver from my computer maintenaqnce kit to disengae lock. Hooked up harness. Replaced screws and shut lid. Main difficulty is my near vision. Requires use of a magnifier I am 80 years old). Your video is great. Gives step by step instructions.

Unscrewed 4 screws,pulled off front of machine.Unscrewed 2 screws holding coils on,unplugged coils,installed new coils,plugged in coils,reinstalled 2 screws for hold down brace.Reinstalled front cover,plugged dryer into outlet(remember to unplugged dryer before working on it).started up,instant heat,works great.thanks Partselect for helping me out!!!

After replaceing several parts including the thermostats the last part I replaced the coils were the defective part. I originally metered out the themostats and they appeared to be okay but since this was my first time I thought I might have been mistaken. It turns out the last part I thought it could be was the part that was defective. I will say that it is very simple to replace any of the parts involved. The hardest part was trying to open the dryer itself. But after having to do it 3 times, I'm now a pro. I also replaced the drum belt and since I had it open I also replaced the belf idler with a newer modified idler rolller.

Putting the belt back on is easy, but it helps to view the video or a picture to understand how the belt goes around it.

I removed the two screws holding the access panel, and removed the access panel. Then removed the lower air duct. I then checked the burner, The solenoid was not opeing the valve for the gas. I order the coils, in two day I had the coils and installed them. The dryer is working great.

When the problem first came up, I took the dryer apart without first looking up any instructions. This wasn't difficult, but didn't realize when removing the fan from the motor, there is a square lug as part of the fan hidden by the rear clamp securing the motor. I was able to remove the fan by holding the motor shaft with a crescent wrench and removing the fan by hand, but was difficult and gloves were necessary in case the fan loosened quickly and my hand came in contact with the sheet metal (very sharp).

I took the motor out and attempted to clean it as it was loaded with dust as was the dryer internals. I tried to lube the motor bearings and appeared to free up, but the sight of metal shavings on the rear bearing seal had me concerned. This ultimely did not work and was trying to buy some time until the new motor arrived.

This is when I looked up the motor part number and found that Parts Select had the part number in stock. I ordered the motor on a Saturday afternoon and got a quick response acknowledging my order. The motor shipped that following Monday from Fresno and arrived on my Southern California doorstep Tuesday. These guys have their act together and are helpful in making the repairs. In my case I did not have to make any adjustments to the wiring or the pulley for my model and replaced the motor the following weekend in about 45 minutes. Since I had the unit apart several times before replacing the motor, the installation went quickly.

The dryer is again working fine for a unit 12 years old and my wife is once again happy that we didn't have to purchase a new dryer.

Removed top and front of dryer then drum and followed the instructions in the package. It was a real simple procedure. I did additional cleaning while the dryer was disassembled.

it took loess than 10 minutes to change the door switch after watching the repair video

Partselect order confirmation email included video instructions of how to change the door switch on my model dryer. Like others I had a pause with the switch connector. I viewed the video again and the instrucions showed to use the putty knife tip to push down on the connector tabs and it came right off. Replacing the switch was easy as the video instructions. Fast shipping of the right part at a good price. The video was pricless. Thank you partselect.

Found a U tube video to be useful. Remover 2 screws under the filter lid. Used a putty knife blabe wrapped in masking tape to unclip the lid. 2 screws to remove the switch. Biggest difficulty is seperating the electric connector. installed replacement switch and closed lid.....reality is this is a 15 minute repair. The extra time was to take the time to remove dust and lint from behind the dryer. Easy repair.

I typed in on my brouser Repair Kitchen Aid Dryer door switch.
And on You Tube up came several videos showing me how to ewmove the switch and install the new one.

The hardest part of the job was not instaling the switch but the dryer Vent hose from the back of the dryer after I puled it away from the wall, it disconnected and the I had to Pull the Washer out which was right next to it so I could put the vent hose back to the dyer. I has to disconnect the Hot/cold water line pull the washer out connect the dyer hose reconnect the cold /hot water lines and yada yada yada

Checked four thermocouples all showed continuity with my multimeter so they were all good. I'd read that the coils commonly went out and that these were the symptoms. Hey, it's very simple in there. Not much else could be wrong. I had a Maytag repairman come out. At first he said the problem was a blocked vent. I knew he was wrong. Then he said one of the thermocouples went out. It was $80 for him to come out. It turned out that his second diagnosis was wrong too. To repair the dryer by Maytag would have cost me $240. I gave him $80 and bought the coils for $37. They are EXTREMELY easy to replace: two screws held a bracket that held two coils. With the bracket off, I took off the old coils and slid on the new ones.

Getting to any of the parts in the Maytag dryer is easy. Tip the dryer back and slide a 4 x 4 block under the front edge. You remove the whole front panel after you remove two screws at the bottom corners of the front panel. You need to tip the dryer back to get a screwdriver on the screws. Swing the front panel up to release the top of the door panel from the top. Watch the short wires to the door switch. Unhook the door switch wires and move the front panel out of the way. The timer on the top is accessed by re-moving two screws along the top edge. There are four screws. Remove them all and tip the top of the front panel forward. You then see that two screws hold the panel and the other two screws just hold the trim.

The dryer started normal. The drum motor run when the start button was operated. The fluff cycle operated normal to indicate the timer motor was OK. On the dry cycles, the igniter heated up. The gas came on. The dryer run for some period of time and then the flame went off. The thought was that the low temp cycle thermostat sensed the dryer was hot and thus switched over to time the cycle to its end. However, the low temp cycle thermostat tested good with a meter when the sensor was removed from the dryer and heated with a light bulb. Burnt contacts in the sensor were a possible problem. I also though the radiant sensor may be bad and not recycling after it got hot. After time, the igniter would cycle on but the gas flame would not come on. I thought the radiant heater might not be tripping the secondary coil on the gas valve. The gas valve coils tested good. I was checking them cold after the dryer had cooled down. I ordered a number of parts.

I got lucky and did a test on the coils while the dryer was still hot. One of the coils in the dual booster holding coil was going open when hot. When cold it had enough continuity to let the gas valve cycle on once. After the coil got warm it went open and shut the gas valve off. When the coil did cool off, it again had continuity. I was about ready to trash the dryer when I finely found the problem. I am happy I persisted and worked the problem through to a solution. I purchased several extra sensors but saved money in the long-run. I rate this problem at the high end of complexity for the do-it your self home owner to solve. The problem was an easy fix once the real problem was found. Only 4 screws and 3 push on wire connectors (two were on the front panel for the door switch).
