7MMGDC410BW0 Whirlpool Dryer - Instructions

First I unplugged the dryer, then removed the back panel, this exposed most all of the wiring and I could see the heater coils.
Not knowing what the problem was I started looking at the coils and could not see any broken parts.
So then checked the thermal fuse for continuity I removed the two wires from it with a small pair of needle nose pliers, it was held in place by two screws, once they were removed the fuse came out easily, I checked continuity with a volt meter placing the meter on X1 Ohms and could not get a reading.
I replaced with a new one and put it all back together the way I took it apart.
Then I plugged it in and it worked first time, I now have warm dry clothes.

i was able to go on line with your company , find my dryer, order the part and had it the next day. fast , great , service

Cleaning the lint out of the whole machine took quite a bit of time--it was everywhere. Underneath the lint trap was a collection that ultimately ruined the thermal fuse where it restricted the air flow considerably.

Ascertaining the problem was the most time consuming part.

The actual repair was quite simple and didn't take but 15-20 minutes.

Pryed dryer top open and opened front door. . Unscrewed the 2 retaining screws. Pulled old switch from the wiring harness. Put new switch in place and replaced the retaining screws. Put new switch wire plug into the wiring harness. Before closing top, checked door switch function with dryer on. Dryer cut off when door open and when closed dryer started normally. . . Maint. Note instruction book should warn that letting door slam, which I did on occaision, broke the switch arm. Might save future problems.

First removed front and drum to check gas valve and igniter. No gas, no ignition. Checked power to devices; none (check hot line to ground, not to neutral.). Removed back of control panel looking for a relay or something. Found none, but did find a wiring diagram. That is where the site really came in handy. Studied wiring diagram together with the exploded view and pictures of each part to come up with a troubleshooting plan. Took the back off as well as a cover inside. Tested each part with meter, again going to ground and not across the device. Of course, the final device before the gas valve, a one time thermal fuse, was the bad part. At first assumed just a bad part. Later wondered if fuse did it's job and another part was bad. Ordered and installed new thermostat just in case. Put everything together after a complete cleaning and everything is fine so far. Not a particularly hard job because I had the wiring diagram and access to parts select site. Would have been much harder without them. Took a long time because almost the entire dryer had to come apart. But it got a good cleaning because of it and found a couple of bucks in change to help offset the cost. Can't imagine what a service call would have cost.

Repair was very easy. We are in the internet age so I use it all the time to get info on how to repair any thing in the house including cars. This time it was my dryer. I typed up 'Kitchen Aid dryer has not heat'and pressed searched and PartSelect came up. Typed in the model number and looked up the comments on No Heat. They had pretty cool site that shows videos on how to repair this things too. Came to conlclusion that the THERMAL FUSE was the main problem. Ordered it and as well as the Igniter assy just to make sure and as well as save on the shipping just in case. Ordered on Sunday night and the shipped the next day. It arrived on Tuesday. Unfortunately had a little problem on the shipment. Called PartSelect and they are so awesome they shipped me new parts asap at no extra charge. Awesome Awesome! Parts came in Thursday and first installed the Thermal Fuse and BAAAM! problem solved. Did not need the igniter assembly. Now I have an extra part in storage.
To replace the Thermal fuse.
1. Disconnect Dryer from power outlet. Remove the bolts on the back panel with a 1/4" socket. I used power drill because it is much faster.
2. Locate the Thermal Fuse. Disconnect wires and remove the bolt. Slide it up and pull. Install the new one and reconnect the wires. Replace the panel and plug the dryer.

That solved my problem. It should solve yours too. The whole process was less than five minutes.

PartSelect showed seven different possibilities why the dryer wouldn't heat. I removed the two screws to remove the bottom panel and turned the dryer on and noticed that the heating element that ignites the gas was working fine. This meant that it was not getting gas so it could be the gas valve or one of the two gas valve coils which are located on top of the gas valve. I borrowed my neighbor"s ohm meter and touched the two probes on the coils terminals to check for continuity and found that one of the coils read zero. I then took both of the coils out by removing two screws and tested each coil again. One coil read 500-850 and the other read zero. This meant that it was no good so I called for the part and received it in three days. I reassembled the parts and turned the dryer on and it fired up after a few seconds. It works as good as new. The part plus shipping was less than $30. My repairman would have charged me $150-$200. While the dryer was apart I gave it a good cleaning with a vacuum and a toothbrush in delicate areas. I also removed and cleaned the lint trap housing by removing two nuts. I didn't know much about gas dryers, but thanks to PartSelect I easily fixed it myself.

It was simple once I figured out what to do:). I removed the 2 screws on the top of the dryer... they were a bit hard to find. Even with the other descriptions on this site. I was removing things I didn't need to. The 2 screws you need to remove are under the LINT COLLECTOR LID. Remove those 2 screws & lift the lid... it will be tight at first. the front of the lid has 2 "catches" in the corners.

The hardest part was getting the door switch assembly to "unplug". We pried it off -- eventually -- & then simply plugged in the new one.

Saved me LOTS of money & was worth the 30 minutes - 1 hour of work.

As I said previously, once you realize how to get the lid up & manage to pry off the plug, that's all there is to it -- easy!

Save yourself time & money & do it yourself!

Grow a second set of hands. Always unplug any appliance. Remove lint screen. remove two screws (philips Head). I took a wooden shim lightly tapped w/hammer to pop front of dryer top free. Mine worked on hinges and just flipped back til it rested against the wall. Removed two 5/16 screws inside holding face on carefully raise face section off the support clips at either side on the bottom. Pull drum out (I have the large style drum commercial size [approx.). Clean the inside free of all lint (known to be fire hazard). Sling new belt around drum. Get newly grown set of hands to hold drum in place. Pinch belt to fit between tensioner, lift tensioner and place belt around motor pulley. Spin drum couple times to make certain belt isn't twisted. Reverse dismantle proccess to put back together. Replace all parts that come with kit, you'll feel better knowing you got a new dryer, almost.

There was no problem with lint build-up within the dryer & the exhaust vent. I removed the gas cycling thermostat & thermal fuse from system & dryer still was not operating correctly. The radiant sensor & hi-limit thermostat both seemed to be operating correctly. That left either of the two coils as the culprits. I replaced both coils & the problem was corrected.

Timer wasn't working on the regular cycle so I replace it with a new one from partselect. It still wasn't working so I ordered and replace the cycling thermostat, the thermal fuse I also cleaned the vent and dryer it still didn't work so I read the diagram for the electrical and found that a coil for the gas valve is line with timer. I ordered the coils for the valves, replaced both valves and tested the dryer and it work just like when I first bought the appliance.

First unplug your dryer. Then, I removed the two screws on the lint trap leaving the lint trap in place--do not pull out the lint trap--only remove the two screws. Next, slide the top of the dryer slightly forward in order to release the top of the dryer. I did this with my hands. Once the top of the dryer is released, raise the top of the dryer and unplug the door switch assembly. Then, remove the two screws that hold the switch. These two screws were located on the front panel of my dryer and are visible when you open the dryer door. Remove the old switch and install the new switch by putting the two screws you previously took out from the old switch back in place and plug in the new switch. Lower the dryer top. Push the top back to lock in place. Line up the lint trap holes for the two screws that hold it in place and replace those screws. Plug your dryer back in and it should work properly. Very easy repair. We ordered our part one morning before noon, and it was here the next afternoon with regular shipping. GREAT SERVICE.

Determining the problem was the hardest part. With multiple parts (coils,thermostats...)possibly causing similar symptoms, I narrowed it down to the two coil valves.
Un plug the dryer. Remove two screws at the base of the front panel. Turn the front panel 180 degrees to avoid disconnecting the door switch. Gas valve with coils on top are on the right in front. Remove two screws in bracket holding coils, disconnect the wires, replace with new coils and reconnect wires. One coil has 2 terminals the other has 3 no chance of crossing the wires. I used an offset/right angle screw driver for one of the bracket screws due to close proximity to the drum. A stubby phillips head will work. You can check the burner operation with the front panel off as long as the door switch is still attached. Swing the front panel around and lift back into place securing with the two screws. Dryer works fine now.

After looking on the website for advice I walked throught the simple steps of disassembling the front, removing the drum, removed the back, disconnected the wire harness. Then removed the blower housing in the back. The blower, mounted on the back side of the motor was very tight. I used a pipe wrench wedged in place and help by my 10 year old Grand-daughter while I used an adjustable wrench to turn the shaft on the front of the motor. Spun the blower off, removed the two clips holding the motor. Then reversed the process when I received the new motor. Care should be taken to avoid damaging the blower fan if a lot of pressure is required.

couldn't get blower wheel off of the motor. really tight. rounded off the wheel's square hub while trying to hold it still as I turned the motor shaft out. No, I wasn't turning it the wrong way :) I ended up going to the back of the dryer and using the multimax to quickly cut the wheel away from the hub. I love that oscillating saw! Just for fun, I put the motor in a bench vise and got the wheel hub off (in pieces). VERY tight! Ordered new wheel, and the job was smooth sailing from there on. I am guessing that experienced repair people automatically order the motor and blower wheel at the same time(?) BTW both parts were perfect matches for the originals. Not surprised; this has always been my experience with partselect.com!
