7MMGDC300DW0 Maytag Dryer - Instructions

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.

Took back cover off
Disconnected part
Put new one in
Reconnected wires
Put back cover on

To verify that this was the needed part, I used a digital multimeter to confirm there was no continuity.

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

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

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.

just slide the new filter in.

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.

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!

Followed simple instructions to replace two pulleys and belt. The Virtual Repairman helped me identify the cause in minutes. Took another 5 minutes to place the order and the part arrived two days later. Saved $125 at least. Thank you!

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!

1 screw to replace.

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!!!!

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!

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.

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.
