7MMGDC400DW1 Maytag Dryer - Instructions

Replacing the part was easy: unscrew the old one from the front of the dryer after opening door, disconnect and replace with new one. Getting to it was a bit more difficult: Remove 6 screws from the back, 4 that hold the back of the top down and 2 that hold the control panel in place. You had to remove the control panel to free up the wiring bundle (held in place by a tie wrap inside the control panel housing) so you could move the top forwards enough. Then remove the top of the dryer by lifting the back up slightly and moving it forward to disconnect from attachments in the front and move aside to gain access to the switch.

Remove back panel n u can see the sensor and easy to replace thanks to the print out i was provided love this website

First, removed the bottom cover below the dryer door. This is just held on with two clips that can be pushed in with a flat screw driver. Then remove the springs that go from the bottom of the dryer to the inside of the dryer door. We had to remove the entire front of the dryer, so the easiest way we found was to loosen the two screws on the bottom of the front panel, but not remove them. Then pop up the top of the dryer. To lift the top, first remove the two screws under the little door where the lint trap goes. The top is hinged in the back, and it snaps down onto two clips that can easily be popped up with a flat screw driver) With the top opened, there are two screws accessible. When the front of the dryer is removed, there will be nothing to support the drum, so what we found was that if you rotate the drum, you'll find a point where there's a hole in the top of the drum. If you take the springs that you removed from the bottom of the door you can hook them into this hole, and hook the other end into a hole in the back wall of the dryer just behind the drum. The springs are the perfect size for this, and it keeps the drum from falling when you remove the front panel. then just disconnect the three wires going to the switch inside the front panel, and remove the two screws from the top of the front panel. It should then lift right off. The bearing can just be pulled away and the new one installed. Put everything together again in reverse order.

The repair was fairly straight-forward. I removed the front of the dryer, lifted the top off, and then released the tension off the belt dy depressing the pulley arm. Once the belt was off, the drum came right out and then it was on to unhooking the wiring from the old motor. Very simple up till this point. The snag came when I went to unthread the impeller fan off of the old motor shaft. It was permanently sealed onto the shaft so I had to cut the old shaft into using a reciprocating saw was a metal-cutting blade. Once this was done the new motor installed easily exactly like the old one was mounted. I had to also purchase a new fan due to the fact that I was unable to remove the cut shaft from the old fan. All parts worked great and the dryer assembled back together easily. Works like a new dryer now.

Sensor is in the front lower left. Gas off, electicity off. Removed two screws for the filter, pry/lifted the top up and taped it too the overhead cabinet, removed two screws inside top of front panel, lifted pandel with door closed staight off. Two screws to remove the flame sensor braket. unplug the old sensor install the new one and reverse everything. With others suggestions I purchased temperature switches etc. but the radiant flame sensor was the problem. I now have some spare switches for future. Excellent company and very quick service. Oh, Sears wanted 200.00 just for the service call, I live rural.

For the Ignitor - As involved as taking the dryer completely apart sounded, it was super easy. 1-take out the lint trap and remove the two screws there. 2-Pop open the top with a screw driver and swing the top completely over/back. 3- remove the two screws holding in the front panel and remove the panel. 4- loosen the belt by pushing on the tension roller under the drum on the right and remove the drum (its super light) use the belt as a handle. 5- remove the screw holding in the ignitor and replace it with the new one. Be careful to not touch the new ignitor. Then go backwards putting it back together.

Really simple, the dryer repair guy I had out did not have the part and wanted $100 to fix. Did it myself quickly and easily and the dryer is working like a charm.

Nothing to it. Just remember to put the insert in the knob, NOT on the selector stem. Line up the flat part of the insert with the flat part of the stem and push the knob in place.

Don NOT ram it on the selector stem. When it's seated, don't push any more. That's all there is to it. It works. If the pointer on the knob indicates the selector is lined up correctly, but it isn't, the problem is the selector, not the knob.

loosened two screws on back of top,lifted top away from front panel.it just lifts off front corners,removed two screws at top corners.lift front panel up and out,this panel supports dryer tub,remove slowly,unplug door switch parts are located left side bottom two screws holding in had to have wife hold drum up to put front panel on

Ohmed coils and both had continuity so I changed radiant heat sensor. No bench test for Radiant Heat sensor. Same problem. Changed both coils and dryer works fine. Weak coils were my problem. I read thru the same issues in Parts Select forum and it said Radiant Heat sensor was problem 25% of the time. With coils having continuity and no ohm value specified for coils I made wrong choice but, I have spare parts and look for another 10 years of life in the dryer. Nice to have this forum to research appliance repair. Very helpful for parts location and installation. Dishwasher is next!

Thermal fuse was blown so I replaced it. Still no heat. Hi-Limit thermostat and Cycling Thermo. had continuity as did flame sensor. Igniter tested 66ohms. I placed a wire jumper across the Hi-Limit and the igniter glowed, solenoids opened and gas came on. I orderd the Hi-Limit and since both "overheating" limiters were defective I decided to order the cycling thermo just in case. The Hi-Limit was received in 2 days but the Cycling Thermo was backordered. In the meantime my wife got antsy so I went ahead and installed the Hi-Limit and put her back in service... ...for one load. I wasn't certain if I had fried the "limiters" again but since they had continuity and I could measure continuity all the way to the Igniter I decided that it HAD to be the cause. I ignored the flame sensor since it never came into play without the igniter glowing... The igniter arrived and measured 56ohms. Hmmm... After installing the problem was solved. Word of advice: If the thermal fuse is blown and even if all else in the circuit SEEMS ok, go ahead and order the Fuse, Hi-Limit and Cycling Thermos, and the Igniter. It will take you about 30 minutes to install and you'll reduce your out-of-service time! Good luck!

Unplug dryer. Remove the front bottom panel of dryer 2 screws, then unplug wire connector to the old igniter then unscrew one screw holding ignitor then wiggle out. Open new igniter wiggle back in place insert screw tighten, (getting this screw back in is a little hard) replug wire connector to new igniter replace front panel with two screws. Plug in dryer and there you go drying clothes again. Wife all happy again.

Be very careful of burrs on the edges of the steel inside the dryer. I cut myself badly when reaching into unplug the switch.
Procedure: Lifted the dryer top by pulling forward and rotating front up. Removed 2 philips screws holding the switch at the door. Reached into dryer and unplugged bad switch. Inserting small blade screw driver at the edge helped release the plugs detent. Installed new switch using reverse of above.

1 screw to replace.

this was very was very easy. But I deviated from the You Tube instructions. One to release the motor pulley. I needed to use 2 adjustable wrenches for a longer lever. I needed to use a hammer to help release pulley. Second to remove the dryer cable I needed to use a small screw driver to aid in the release. ---- the part from the company was a perfect fit.
