7MMGDC300DW1 Maytag Dryer - Instructions

Took everything apart, replaced the igniter flint, and still didn't get heat. Then found out the thermal sensor wasn't running a electrical current through it with voltmeter and just replaced that, now it we have heat again!

Solution: electric motor replacement as the integral centrifugal switch lever (plastic cam) wears over time causing the start windings' switch poor contact. Took it all apart, (back panel, front and top) including lifting the drum out to completely expose the motor. Needed to wrench the plastic fan from the inside motor shaft. Tricky part was swapping the original pulley (6 rib belt, still good) for the one supplied for 4 rib belts. I needed to file another flat onto the other side of both motor shafts (old and new) to break them free, using a vice to secure the pulleys. The dryer works perfectly! It's a great dryer that can be repaired by a determined novice. The enclosed instructions were helpful, although if followed about cutting the original motor shaft to obtain its pulley might require drilling the shaft from the pulley = nonsense. Thanks again Parts Select.

I looked at the parts breakdown to see how it cam apart.

I tore the dryer down,
1. removed the door
2. openned the top
3. removed front panel
4. removed fron bulkhead
5. removed belt and drum
6. removed back cover
7. removed the ductwork
8. removed the fan (this is the hardest part, it is very tight on the motor with left hand threads, there are flats on the (inside of the dryer)fan where the motor shaft goes into the fan for a wrench and you can put a socket on the front pulley on the motor. I ended up just knocking the center out of the fan and replacing it.
9. removed the motor and cleaned the entire unit
10. reinstalled everything in reverse order. Note:I went ahead and replaced the idler pulley and the rear wheels that support the drum, and put a new belt in (just about
everything that could fail) I spent about $200 to keep a $1200 dryer in service at least another 7 years.

Replaced both Coils. Purchased M Series coils much less expensive buying coils together instead of seperately. Problem solved.

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

Shut off gas removed gas valve. Removed the coil retainer and installed the new coils. Reinstalled valve and checked. Found dryer worked fine.

I had an issue where I was not getting any power to my ignitor. After replacing the ignitor with a fresh one, the problem persisted. Next, I went hunting all the fuses and therrmostats for continuity. All seemed fine. So finally I decided to jump the flame sensor which is located on the outside of the flame tube. WHALLA! It ignited the glow plug. So with one 1/4"" nut driver I removed the single bolt from the unit, then I used a pliers to remove the two wires from the old unit. I replaced the sensor with Tue new unit and all was well. It took less than 5 min once I diagnosed the problem.

just slide the new filter in.

My Whirlpool dryer had no heat. I removed the back panel and within minutes diagnosed the problem to a blown thermal cut-off fuse. I ordered a thermal cut-off kit on a Sunday night and had the parts at 7:30am Wednesday morning. Total time for diagnosing and repair was no more than 15 minutes. PartSelect saved me a ton of money and aggravation!!! AWESOME!!!!

1 screw to replace.

At first I was advised to replace the temperature overload sensors, which I did but didn't fix the problem. After adding the additional information that the dryer would run to full cycle as long as the Start switch was held in I was advised to replace the Start switch.

It wasn't obvious from the wiring diagram, but if you remove the Start switch and look at the side it shows it contains a solenoid holding circuit that keeps the switch in the "on" mode as long as there is a feedback signal from the temperature overload switches. So if the dryer will run to completion if the switch is held in, replace the Start switch. If it still stops mid-cycle, replace the temperature overload switches.

The replacement videos were spot on as far as clear and easy to follow instructions for the repair, and all ordered parts were delivered very quickly.

Thanks for your help PartsSelect!

First I did a search on dryer repair. Found a website that described easy things to check with an ohm-meter. I then performed the continuity checks on the items and found the high-limit one was open, in other words, no good. It works similar to a fuse. All this was done after removing the back panel, just a few screws. The reason it exceeded the high limit, possibly because I never opened the back up and cleaned it. Found out it should be done every couple years. My vent line had a hole in it and was letting lint get drawn into the heating element, could have been a fire.

The cycling thermostat was found to be not working when I checked it with a ohm meter. I ordered the part waited and installed it and it work just fine.

Took of the back cover, and removed the vent connecting the blower motor to the drum. It was completly full of lint, so cleaned it out completly, and tried the dryer again. The heater element was still cutting off early, and the clothes were not getting very warm, but better than before. Decided to change the thermal cut-off switches. Ordered the parts on Sun, they came in on Tuesday. Dryer was up and running Tuesday night. Just 2 screws per switch, took less than 1/2 hour. The dryer now runs like brand new, and my wife was ready to fork over $800 for a new one!
