GDE7800 Maytag Dryer - Instructions

Removed the frong cover and and internal sheild, removed and replaced thermostatic, wiring as original.
I had searched several other sites first for thee part, but none of them seemed accurate. Your photo matched the old exactly, giving me the confidence I wanted before ordering.

I opened the back acess panel and started the dryer. Looking at the motor and idler pulleys it was obvious by the frequency of the squealing noise that it was coming from the idler pulley.
I pulled the retainer clip and tension spring from the idler pulley and removed it. I applied some grease to the shaft and reinstalled the idler pulley.
The squeal was gone confirming that the pulley bushing was dry. I ordered the new idler pulley and when it arrived the next day I cleaned the grease off of the shaft and installed the new idler pulley. Problem solved.

1. Removed two screws from front panel.
2. Removed panel.
3. Removed four bolts off tumbler face.
4. Removed face.
5. Removed drum and belt.
6. Vacuumed.
7. Replaced idler spring assembly.
8. Replaced drum.
9. Replaced belt.
10. Rotated drum to make sure belt was properly seated.
11. Replaced tumbler face.
12. Replaced front panel.

Insure the double pole breaker in the breaker box is functioning properly.

used a utility knife to open the box in which the part was shipped, discarded the old filter and inserted the new one

All you need for a Maytag is a snub nose Philips screw driver. The screws on the front panel are at the bottom angled down, so a regular length Phillip's won't work. Just unscrew the 2 screws, then lift the panel up and out. Careful not to pull out too far, there are 2 wires attached to the switch. The replacement switch is NOT an exact copy of the old one. My Maytag is over 30 years old and it only had 2 prongs on the switch. The new one has 3. Don't let that throw you. It is the same size. Just attach, 1 wire to the bronze connector & the other to the silver. Push the switch into the door opening, re-attach the door. Total time 20 minutes. Saved well over $100 in a service call. Anyone with an IQ above freezing can do it.

Door switch was very easy to replace as it simply snaps in for the outside and you just clip on the two control wires that already have clips on them.

first i removed the screws holding back cover. Then I remeved nut from tumbler roller shaft. Then I slid shaft from roller .I removed roller then replaced with new one. Installed new shaft then replaced back cover. recieved parts from parts direct very promptly & they were the right parts the first time thanks very much

My first attemp was to replace the drum roller and idler roller, drive belt, and the felt seal for the back, since I had experience replacing these on an older machine many years ago. The dryer was very easy to work on....After installing the new parts, I reassembled and discovered it still made the same loud noise. I then, disassembled for the second time to discover the blower wheel was worn out; so i ordered another blower wheel and a drum support roller (i only ordered one the first time.). After reassembling it made an annoying high pitch sound. I attributed that to the new parts...probably the new belt and new felt seal. Gave it some time to run-in and it seems to have quieted down. Overall, i found the dryer very easy to work on. I actually found the felt seal the most onerous to install....needed to have about three hands to get the drum back in place! I just wish that the stamped metal dryer housing didn't have such sharp edges. I had to be very careful to avoid sharp burrs but still got nicked a couple of times.

The repair video is terrific and many others here have thoroughly described the steps involved to replace the drive motor.

The biggest hurdle for me was that the motor came with a new switch that required a different wiring configuration. No wiring diagram was included. Several others had posted questions about wiring in the Q&A and unfortunately PartSelect kept copy/pasting the same confusing and incomplete answer over and over:

"The Yellow goes to T6, Red to T5 Black to T2, blue to T1 and the white you will remove the blue jumper lead between the switch terminal 4 and 1/4" protector tab, connect the grey harness lead to the 1/4" protector tab."

Reading that doesn't tell me what to do with the white wire, doesn't address that my blue and white wires were crimped into the same connector from the factory, doesn't address that I had 2 black wires crimped into the same connector from the factory, and doesn't address a factory ground wire that connected the frame of the OEM motor to the bracket that the motor sits in.

With all the other excellent info supplied by PartSelect, this was surprising and frustrating. The sales dept ignored an emailed question from me, and the Q&A section didn't allow me to post a question.

Searching the internet, I found a wiring diagram on aceappliancesd dot com that addressed my dryer's OEM wiring configuration. Here's what I ended up with:

TI - Blue and white, crimped together into a single connector
T2 - Black & black, crimped together into a single connector (the wiring diagram I found said this should be black & brown, but they both look black to me)
T5 - Red
T6 - Yellow
1/4" Thermal protector tab - Grey (from the harness)

The new motor switch had a grounding tab with nothing connected to it. I removed the screw holding that tab into the switch and connected the (also grey) OEM short ground wire from the motor frame to the mounting bracket.

I had to cut 2 of the pieces of tape holding the OEM wiring harness together in order to get enough slack for all the connections to reach. If you do this too, make sure all the wires are still clear of the moving parts and the hot bits. You may need to retape the wires together at a different location to keep things tidy.

I also laid the belt over the drum and put 2 pieces of tape over it to hold it in place while I got the drum positioned, then I reached through the back access panel to loop the belt around the motor pulley and idler. Once that's done, just reach over the top of the drum and peel the tape off. I found that much easier than trying to loop the belt by reaching through and past the drum.

I looked for dryer repair videos on my computer. I found several and they all showed me that what was most likely broken was the tumbler belt. I didn't even know dryers had a belt. My dryer still turned on,and still produced heat. It just wouldn't rotate. One of the videos even used the exact Maytag dryer in their video that I had. After watching it a few times, I knew I could make this repair. I am pretty good at fixing things if I can first see it done. I had never taken a dryer apart before though. I pulled the dryer away from the wall and unplugged it. I unscrewed the small access panel on the back of the dryer. This let me see the two belt pulleys back there. Then I went to the front and removed the two screws(my particular model) that held the front panel on and removed it. I then unscrewed the four screws holding on the front face plate in front of the tumbler. Next, I pulled the tumbler out, it is not screwed in. There was the broken belt. It took two days with regular shipping for the belt to come in. I put the tumbler back in, resting it on its two supports, placed the belt on, flat side down, and routed the belt through the pulleys in the back of the dryer exactly as it had been shown in the videos. I turned the tumbler clockwise two full rotations by hand to make sure the belt was seated correctly on the pulleys, and it was. I then screwed the face plate back on in front of the tumbler, put the front panel back on and screwed it in. I then reattached the back access panel. I plugged the dryer back in and turned it on. It worked. Though it may take a bit longer, this type of repair is about as easy as replacing a broken belt on a vacuum cleaner even for someone who has never done a dryer repair before. Watch a Repair Clinic video and if you enjoy fixing things, replacing a belt on a clothes dryer will be your next successful repair. It really is pretty easy.

This should have been a simple repair, but turned out to be time consuming and moderately difficult. I hope these instructions will help anyone who encounters the problems described here.

After a period of the dryer not being used, the idler pulley wheel froze on the shaft of the idler pulley arm, so I needed to replace both parts. After mounting the new wheel and two washers on the new arm and securing with a retaining ring, I went to install this assembly by going in through the small access panel at the rear of the dryer. I slid the belt off the old idler pulley wheel and unhooked the spring from the idler pulley arm; the arm was mounted on a sleeve fastened to the motor bracket by one screw. All that should have been necessary was to back out that screw and replace the old idler pulley assembly with the new one.

That is where the trouble started. Backing out the screw with a socket driver, I found it would go a few turns, then start to bind. I tried turning it in and out to get the threads to engage, but it kept binding. Eventually I gave the screw a hard turn, and then it would turn freely but not move in or out.

Looking on the internet for advice, I found a video that asserts for another model Maytag dryer using the same type of mounting for the idler arm, that there is a design flaw. You can find the video by searching for “Maytag dryer idler pulley defect”. According to the video, the sheet metal screw used to mount the idler pulley arm can gradually loosen due to the pressure and vibration, and begins to “waggle” which eventually damages the threads. I believe this is what happened to my dryer. The video suggests replacing the sheet metal screw with a machine screw and nut for a more durable union.

So now I understood how the screw could be stripped just sitting in the dryer, but that didn’t help me get the screw out. Working through the rear access panel, I tried pulling on the screw head with several types of pliers, pushing the point from behind with a piece of wood while turning the head with a socket driver; eventually I was able to use a pry bar under the screw head and sleeve to apply pressure while turning the head, and with that method the screw backed out. With the screw removed, it could be seen that the threads in the middle part of the thread length were almost completely worn away.

The screw sleeve got somewhat deformed in this process so I ordered a new one, along with an exact replacement sheet metal screw, hoping the threads in the hole were still intact. With the old idler pulley arm now removed, I could transfer the old idler bracket spacer to the new idler pulley arm. When the ordered parts arrived and I tried to mount the idler pulley arm, the new screw would go in only a couple of turns before binding. Rather than risk winding up in the same situation by forcing the screw, I decided to use a machine screw and nut instead.

The original sheet metal screw was a #10. A machine screw the same size would not fit through the hole, and I could not fit my drill into the dryer cabinet in a position to enlarge the hole, so I used a #8 machine screw with a nut and lock washer. First I put some grease on the contact areas of the screw sleeve and idler bracket spacer, then inserted the machine screw through the hole and put the lock washer and nut on the other side of the mounting. The space around the nut is very limited, and most of my tools were too large to hold the nut while the screw was tightened. It was too small for a socket or adjustable wrench, and the clearance from the exhaust duct was too small for the handles of most tools. Eventually, I found a needle nose pliers with short handles that did the job. A thin open end wrench might also work. Then I reconnected the spring and belt to the idler pulley assembly, and closed the access panel. So far the dryer works, but if the #8 screw turns out to be not strong enough, I could get an extension for my drill and enlarge the hole to fit a #10 machine screw and nut.

Looking back on the job, the most difficult part of this repair was removing the damaged screw. This and several other steps might have been a lot easier if I had removed the motor bracket (where the idler pulley arm is mounted) from the dryer and worked outside the cabinet. Part Select has an excellent video “Replacing the Drive Motor” that shows how to do this. It would be a lot of disassembly work, but for someone with good assembly skills could be easier in the long run.

Hopefully most folks out there who replace the idler pulley arm on a dryer will find an easier situation than I did. But for any who have to deal with a stripped mounting screw, I hope this summary will help you resolve it.

This website is awesome. After imputing my dryer model I was able to select from the list if symptoms my issue...Dryer will not start. From there was percentage of issues that would cause my issue. After determining it was the motor (after 25 years who would have thought that!!!). In this process I discovered other non related issues that i should attend to. So I basically rebuilt the dryer and it worked right away. I am retired military and in the tax preparation/representation business now, so a lot of this was new to me. The detailed instruction and especially the videos provided foolproof methods to complete each of the repairs. It was a little time consuming but very easy to complete. I did gain some new tools and diagnostic equipment that will come in handy in the future. Now I am going to tackle my daughters dishwasher. Thank you Parts Select and Steve (on the videos).

Disassembled per instructions. Additional time used to clean inside unit.. Its much easier to install belt on motor pulley and tension pulley ( Roller) from rear access panel. Also ensures proper belt alignment on all items.
