7MMGDC300BW0 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.

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.

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.

Followed electrical drawing from switch to motor, Thermal fuse was in the line and no power coming through it, removed wire and put together and tested, dryer turned on. Read statements from others at parts select and also bought thermostat because time stopped working last year. Installed both parts and cleaned dryer, works perfect including timer.

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.

When my dryer suddenly stopped functioning, without any prior signs of pending failure, I guessed that it had to be something simple, like a fuse. I did a google search and stumbled across a forum post that described the symptoms (wouldn't turn on), and the poster said that Whirlpool recommends replacing the thermostat whenever the fuse is replaced. The reason for this is that the likely cause of the fuse burning is that the thermostat is no longer properly regulating the temperature range of the heating element.

I disconnected the power source, and then I removed the back cover, and both parts were in plain view, so I simply replaced the wires one by one.

I first unplugged the electrical plug, then opened up the dryer, front and back. Once I had diagnosed the problem I unscrewed the thermal fuses and thermostat. Marked which color wire went to which connector and continued to replace one wire at a time. Re-attached the mounting screws, verified all wires were connected, plugged in dryer to test heat cycle. Once the dryer worked correctly I vacuumed all lint and covered it up.

I spent nearly an hour trying to self-diagnose the problem before I wised up and found PartSelect.com. After reading just a couple of postings I went back and tested the thermal fuse. It was bad. Other posts suggested I replace the thermostat at the same time, so I ordered both. The parts arrived within three days and the actual repair took less than 10 minutes.

Turned off the power.Pulled the dryer out, removed the screws from the control cover panel, unplugged the switch, pressed the release clip the did the opposite to install new switch. Replaced the back panel, put the nob on and it looks as good as new.Turned on the power.

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!

JUst like a new dryer aain after all PM was complete.

After 30 miutes of research on this website I felt confident to investigate the problem. Removal of the back cover is straightforward. Initially I did not appreciate and obstruction of the ductwork exitting the dryer. I bypassed the thermal fuse by removing the wires and temporarily taping them together and heat was restored. Knowing flow was OK exitting the dryer I investigated flow from the lint trap to the blower motor which is where the problem was located. In our case the lint filter was torn allowing many small objects and lint to near completely clog the pathway between the lint trap and the blower motor. It was difficult to appreaciate how obstructed that pathway was without removing the entire channel from the machine which was simple and required removing two screws at the lint trap opening followed by 3-4 screws on the back of the channel. Once removed, it was easy to appreaciate the debris clogging the channel and was easy to clean with a hose and running water. Replacement was a snap. The parts were oredered and sent in a day. I prophylactically replaced thermastats based upon a recommendation from another website. Replacing previous parts with new parts was a snap. Out the door we were up and running for around $100 (including new thermostats). The dryer repair man may go the way of the dinosaur.

First I took the front of the dryer off then located the igniter. It only required removing two screws, removing old igniter, replacing with new igniter, and replacing the two screws.. While I was replacing the igniter I took the drum out and throughly cleaned the inside. Lucky me, I found 85 cents on the floor of the dryer. I am 65yrs old, married and mother of two.
This was easy to do and sure saved money. I reccommend others try to do repairs for themselves and using PartSelect was less expensive too.

Great! Spent about $36.00 and I ended up with a overhauled dryer. I ended up cleaning the whole thing out, it's amazing how much stuff accummulates in the frame of a dryer, I also found about $2.00 in change. It's a good idea to clean out a dryer every few years and the broken belt forced me to do it.
But anyway the parts cam very quick and had easy to follow directions.
I would reccomend part select. Matt
