7MWG77900SW0 Whirlpool Dryer - Instructions

Removed the two screws that attatch the lent channel to the top of the dryer, then lifted the top of the dryer by pushing in on the two locking tabs located at the front , left and right , corners of the dryer top with a small flat head screw driver. The top of the dryer will fold back out of the way. At this point I removed the two 1/4 inch screws that are located on the inside of the dryer front left and right corners that hold the front panel/door to the two side panels. Now I was able to lift the front panel up and set it to the side. The bottom of the front panel that contains the dryer door that I just removed was held on the bottom by two clips that slide into slots on the front panel and did not require any removal to disconnect the bottom of the front panel, just pull up on the front panel. Since the tub was held in place by floating on a seal at the back of the dryer and a seal on the front panel , which I just removed the tub is now free floating except for the two alignment roller wheels at the bottom of the tub. It is easier if you lay the dryer on its back at this point with front of the tub pointing up. I pulled the tub out and cleaned the years of built up lent and removed all the pieces of the old , destroyed, belt. Note, the belt tentioner is located at the front of the motor which on the bottom right hand side. If your belt is broke like mine the tensioner may/will fall to the back of the dryer when you tilt it back, but do not worry. Once the dryer was cleaned up I put the tub back in place , still on its back and made sure the two alignment rollers were in place and rolled freely when the tub was turned by hand. Another note, my original belt tensioner did not have a rolling wheel that the belt rode on , but was a semi-circle smooth surface that the belt remained in constant friction with when the dyer was running, so I made sure the replacement tensioner I ordered with my new belt did have a rolling wheel that the belt would ride on, which I believe will reduce wear and extend the belt life. The new belt came with a diagram of the belt and tensioner routing which was helpful. Note: do not take the tensioner wheel off/apart when trying to route the belt. Follow the instructions routing diagram. The tensioner is held in palce by inserting the bottom back half into the slot in the bottom floor of the dryer making sure it is aligned with the belt pully on the shaft of the dryer motor. The dryer is still on its back side. Now, it was easier for me to route the belt around the center of the tub, following the marks from the original belt, and hold in in place in a few spots with masking tape and then route it thru the tensioner and onto the front pully of the motor. Make sure you have the grooves of the belt against the tub and the grooves are aligned with the pully on the motor. Now you can remove the masking tape that was holding the belt around the tub and spin the tub by hand watching the belt making sure it is not in a bind and is traveling around the motor pully , tensioner and tub freely. Make sure the tub is still sealed on the back side wall. As you turn the tub by hand you can adjust the belt by hand so that is following the original marks around the tub left by the orignal belt. Also double check the two alingment rollers and make sure they are spinning and on track. Now put the front panel with the door on by sliding it onto the two clips that are one the bottom at each side and put the two screws in that hold the front panel to the two side panels. Now stand the dryer back up and spin the tub by hand again making sure it has a good seal on the back side and on the front panel. Pull the top back down and put the two screws in that hold the lent channle to the top. I am not sure when the belt started failing on my dryer, but was amazed at how quiet it runs now. Guess I was use to the extra noise made by a dryer that was about to die. This was a cheap and easy repair and glad I did it myself.

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

Received your parts, Popped them both right into place, Even though only one side needed to be replaced, I wanted them to match up. It was amazing how easy this was. My husband was quite impressed I had ordered these rather then look for either a new or used dryer from some other source.

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.

Removed some screws and partially dismantled the door so I could get the old catch out. Inserted the new catch, and put the screws back in. Saved me an $80+ service call.
On the filter, I had to use pliers to remove the old one because the handle had broken off. Did that, and inserted the new one. Done. Sears had been unable to supply me with a new filter.

The best part of my repair was I had everything back in service in 3 days. And one of these days was to consider just buying a new dryer. Had parts overnited and all parts fit and easy to replace.

1) Removed back - 6 screws
2) Removed dryer vent - 2 screws on top, 3 on bottom
3) Popped the top open
4) Removed Front of dryer cabinet - 2 screws
5) Removed Belt
6) Removed Drum
7) Cleaned up all lint
8) Pop off motor retainers front and back
Here is the tricky part for me.
9) Removed vent fan on back of motor.
I did not know that the back of the fan was square, and you could put an open ended wrench on it to hold it while you also have a vice grip on the front motor shaft. Then its a simple left to loosey operation. I first tryed to turn the fan blade to take it off, but proved to be to tight.
10) Repeat backwards to reassemble

While I had it apart I also replaced the Drum support rollers & Installed a new belt. Not that diffucult of a repair Good Luck, was certainly better than buying a new one at + $300.00 at Black Friday rates.

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.

I can't believe I waited so long to find this part and do this. I got the package very fast, opened it, took the piece to my dryer and popped it into place with my fingers. It worked perfectly! this took all of two minutes and saved me from having to hold the dryer door closed with a stick. Thank you, thank you!!!

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.

1. Removed the screws from the lint catcher
2. Removed the bolts from upper rear of dryer
3. Pried off the dryer top from the front (it rests on rear hinges)
4. Disconnected dryer door wiring
5. Removed bolt from inside upper front corners; removed front panel (be careful: the edges are sharp and the tumbler will fall when it loses support)
6. Removed broken belt and lint from interior parts; removed tensioner (which had fallen out of place). Note: The newer models have a tensioner pulley; my older model had a smooth semicircle that was confusing at first glance
7. Flipped dryer onto its back (for easier reinsertion of new belt and tumbler)
8. Placed new belt on tumbler; reinserted tumbler
9. Inserted new belt through tensioner, inserted tensioner "legs" into grooves on floor. Note: The belt will pull the tensioner upright when it's inserted properly (which isn't obvious at first)
10. Made sure belt and tumbler seal were properly installed
11. Replaced parts in reverse order
The process took over an hour because I couldn't figure out how to insert the belt through the tensioner. The trick is to insert the folded belt through the tensioner and onto the motor pulley. If I had to do it again, it would take about 30 minutes (including cleaning lint)

I Looked on internet sites for this type of problem.
Most sites said the support rollers could cause this.
I found your site PartSelect and with help of your diagrams of the machine ordered the parts I thought were needed plus other parts that might cause the problem.
With machine torn down I replaced the rollers.
I had also ordered the main drive belt and idler assembly with the rollers and these also needed replacement. It is a good idea to order other suspect parts when doing this type of repair since you can return the parts not needed.
Your return policy is great.
