7MMGDC300DW4 Maytag Washer - Instructions

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.

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.

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.

My son got it in the mail for me and snapped it right back on.

Just popped it into place needing no tools at all. Took less than a minute.

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.

First watched a youtube video on the process. Took off front cover. I'd already replaced a belt so I knew what to expect. Two screws holding the retaining plate on top of Coil Valves (both). One screw was a bit seized, so a bit of persuasion w/ the pliers was in order. There was no info on which way up, but luckily I noticed a bump on each valve, and two matching holes on the retaining plate. (Note to others trying this) Of course while re-assembling a dropped and temporarily lost a screw, then one of the machine screws that hold the front cover on, but other than my stupidity, and frustration that job was easy. The cycling thermostat I just got "just in case". I knew the main thermostat was working, but couldn't accurately check this one, so I got a spare and replaced it. I'm sure it was one of the valve coils as I'd read another user had an issue where the coil would work fine at first, but after it got hot would not work. After a cool down, it'd work fine again. So all in all, easy job.

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).

I disassembled the dryer once to clean the motor and compartment. After reasembly, the problem persistes. I ordered the motor and the second diasasssembly was accomplished in 10 minutes and the entire job took 45 minutes and the dryer was running like new. Tip- Leave the motor secured while removing the blower fan.

Half of my pulley was broken off so there were no wrench flats to take it off. I was able to remove it using Channel Locks and the 7/16 wrench shown in the video.

Hint: Use a one gallon ice cream bucket to hold up the drum while connecting the belt. It makes it much easier and gives you more clearance.

PULLED THE DRYER APART TO GET TO THE MOTOR , REMOVED MOTOR , LOOKED FOR MODEL NUMBER OF DRYER AND DID RESEARCH ON WHERE TO BUY THE MOTOR AND BOUGHT FROM PARTS SELECT BECAUSE BOUGHT FROM THEM BEFORE

I suspected a faulty igniter and disconnected the cable to the igniter and measured the resistance of the igniter and found it to be 70 ohms then I checked the voltage at the same cable towards the power source and found it to be 25 volts ac which should be 120 volts ac. Next I checked the radiant flame sensor and found it to be open (it should be a closed circuit when cold). I removed the flame sensor (with the power off) using a small box wrench and found a broken lead. Replacing the flame sensor solved the problem.

I was reluctant to call a repair service. Typically when an appliance is as old as my dryer (14 years old), service people encourage you to replace, not repair. I had replaced the dryer's motor within the last 5 years and believed my dryer still had life to it. At first, I tried cleaning the lint build up from the dryer cavity and hoses. This worked but only for a couple of days. After reading other successful repair stories on the website, I decided to try replacing the thermal fuse. It was so easy. The part was easily identifiable. It was just a little hard to yank off the connecting wires. Good as new and no service call.

removed front of dryer located igniter removed two screws disconnected wires then put new one in also replace thermal fuse and thermostat on back of dryer works great.
