7MWGD7800XW0 Whirlpool Dryer - Instructions

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.

ordered new lint screen, removed old screen, inserted new screen.

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.

After a few years of slamming the dryer door (at least that is what my husband says), the catch on the dryer door broke. Using pliers (I used needle nose) squeeze the outer edges of the catch together (vertically). With it compressed, it should slide out easily. My husband had jacked with ours prior to the repair, so the broken piece in the door was actually sideways and would not fit through the hole. Using a screwdriver, I pushed that piece into the door (it lives in the door somewhere now). I was then able to slide out the rest of the old catch. Compress the new catch and insert it into the hole in the door. Push it in until it clicks into place. DONE! Happy Drying!

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.

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.

I removed the two screws holding the front panel to expose the lower works and verified the heating cycle failure. After a check of the vent system, checking the sensors for continuity and coils for resistance, I retired to the 'net for support. Accepting the general consensus that the most frequent, common and likely failure to be the coils, I rechecked them with the meter and found the two pronged coil to have significantly more resistance than the three prong coil. That was enough evidence to point to the coils. While I waited for the part to arrive, I replace the vent ducting. When the parts arrived I removed the two Phillips screws holding the coils, removed the old ones, installed the new ones, replaced the bracket, put the front cover back on and in less then ten minutes clothes where drying.

The issue was the idler pulley. First I began opening up the front panel based on a youtube video but soon realized the model was slightly different and required a lot more items to remove. I saw the pulley in the back with nothing in the way so I put the front panel crap back on and removed the rear panel. There it was, very simple to remove and replace. I'm not looking forward to drum rollers though. Hopefully they're aren't as difficult as they appear.

1 Unplug power.
2. Remove the front of the unit by removing the two screws at the bottom of the front panel. Front dryer panel will swing out from the bottom and then the clips will release the top of the panel, careful not to disconnect the dryer door switch. ( can be unplugged to remove the front panel out of the way.)
3. Looking inside the unit on the right side you will see the gas value. On top of the gas unit you will see two small coils the coil closest to the burner has two leads on it. Remove the two screws to get to the coils, remove the medal plate, remove the connector then lift off the secondary coil. Replace and test. You can test unit with the front panel off. (be careful). If no heat, check that the Flat Style igniter is glowing. (ohm out both coils) before ordering parts. Intermittent heat problems. I replaced the secondary coil, it did ohm out o:k but it had swollen and was very tight on the shaft.

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.

Found this site by googling, and it works! I searched lint filters and just ordered based on how it looked...LOL! Husband wasn't home, it looked pretty much like the one I had in my hand, so.... I ordered it. It is the perfect fit and seems to have a tighter gasket glued in all around the screen. Let's hope this one lasts longer than 6 months! Thank you Parts Select for being so fast!! Filter got here in less than 48 hrs.!

I changed out the cycling thermostat and the high limit thermostat. Mainly because that was what my research indicated was the problem. I then found some more information online that indicated the gas solenoid valves were bad. I ordered them from you and replaced them. The problem was fixed.

In order to replace the valves you need to remove the top panel. Two screws at the top of the front door assembly hold it on. Remove the screws, lift up on the front panel door assembly and move it to the side. The drum will rest in place. In the lower left corner, under the drum, you will see the solenoids. Two screws attach a plate that holds down the solenoids. Take the hold down plate off, disconnect the control wires attached to the solenoids and lift out the solenoid/control valves. To assemble everything, work backwards to the start. Good Luck

I purchased the dryer repair kit with the drum belt, wheels and idler pulley. I watched the instructional videos online and it seemed fairly straight forward. Breaking down the dryer and replacing the pulleys was easy enough. My problem began when I tried to feed the drum belt around the idler pulley. After finishing the job, the dryer would not turn and the sensor light stayed on. I thought something else was broken with the dryer and spent hours trouble shooting other problems that I was having. Finally I figured out that the drum belt was not installed correctly around the idler pulley. However, I could not get it properly installed from the front of the machine so I tried from the rear still with no avail. I finally had to fish the old belt out of the garbage can that I had thrown away earlier. I lined up the old belt with the new one in the kit and discovered that the new belt was much smaller, so I put the old one back on the drum. Here's the lesson I learned...make sure the belts are the same size before attempting to install. The old idler was responsible for the squeaking and that stopped but I am still using the same old drum belt. Hope it lasts.

After reading about other people with this same problem I took a chance that this would be what was wrong with my dryer.I took off the front cover of the dryer by removing two screws. I located the faulty coils and simply plugged in the 2 new coils Tah-dah Probably coud have been done without even removing the front panel, but since it was off I vacuumed out the lint ( actually my husband did all of the above, but I tell a better tale than he does and I diagnosed the problem and ordered theparts)

I found that the dryer would not start turning by itself. Could manually help it start and it would run fine. Anyway, after a new set of rollers, belt, etc. found that the motor still would not start by itself. Ordered new motor and it was taken care of. You have to take the back off, remove the belt and remove the tumbler. After that, it is fairly easy. Two screws hold the motor down and then you can take the whole motor assembly out. Be careful removing the fan as it takes a 3/8 socket drive and it is plastic. Two clips hold the motor to the assembly. Needle nose pliers takes care of it. Replace and all should be good.
