SG7800 Maytag Washer Dryer Combo - Instructions

first, I unplug the power supply of the dryer then I removed the two screws at the bottom of the dryer then pulled out the front part of the dryer,unplugged the blue & yellow wire for the on/off switch for the door,at the back of the dryer I unscrew the pannel for the belt,disconect the belt,and I unscrew the four screws on both side of the front pannel to remove the front cover of the drum. Once I removed the front cover of the drum I can now remove the drum itself to access the drum support roller. I unscrew the rollers then replace it with the new once. It was an easy job.
Thank you.

I started by unplugging the appliance and then shut off the hot and cold water faucets then I disconnected and drained the hoses. Next, I removed the two screws that held the valve assembly in place. I then pulled the assembly out about 3 inches and disconnected the two wire plugs. The last step was to loosen the hose clamp on the outlet hose and pull off the outlet hose. I reversed the steps to install the new assembly and the total repair took about 10 minutes.

Removed the front cover (screws on bottom 0f face)...removed blower cover....spring pliers to remove and install blower fan. the rest of the time was spent cleaning the inside of the shell as well as the vent. Reassembled and dryer runs better than it has for many years.

I removed the 2 phillips screws on the bottom of the front panel. Then checked around to find the belts were actually below the floor panel.
I pulled the washing machine away from the wall and tilted it bacwards and found the pump belt was off the pully and the drive belt was badly damaged. I replaced the 2 belts which took no tools and about 3 minutes to accomplish then resecured the front panel, pushed back in place and leveled. Complete repair from diagnosis to back in operation took less than 15 minutes.

Unplugged dryer. Front came off easily. Removed front of blower. Wheel came off fairly easily - could then see that shaft of motor was circular with flattened side but inside of old wheel was rounded. New wheel popped right on. Took tumbler off so I could clean lint out more easily and get a good view of how the belt threaded through. Put the tumbler back on and reached back with both hands to thread it. Took a half dozen tries until I was sure it was seated correctly and not twisted. Put front... of dryer back on. So far (a week or so) the rumble is gone. Seems blower wheel was the cause of the rumble. Belt didn't seem worn but replaced anyhow.

My washer is 5 years old and water began to leak on the floor. I took off the front panel and filled the tub. Water did not leak immediately, but after the tub filled with about 3-4 inches of water, the water began to leak from a rubber washer between the fixed tub and the drive shaft. I looked online for exploded diagrams of Maytag washers, when I came across your site. By looking at your diagrams, I determined what parts I needed and ordered them. The parts arrived in 2 days, and I installed them. There were no leaks and it cost me under $70 (a repairman would have cost at least $250). The only thing I would recommend to those in similar situations, is to purchase a spanner wrench (your site does not sell, but others do). The stem seal and hub assembly is reverse threaded (clockwise to loosen) and is difficult to remove due to tight quarters in the tub.

1. Removed front of machine (2 screws at the bottom).
2. Removed 4 screws from inside the dryer, to take off the blower housing.
3. Removed 4 screws and took out the large metal piece which supports the drum at the front. Removed the drum.
4. Replaced the two rollers that support the drum in the rear. Cleaned the pins they run on, and oiled very lightly. Also replaced the idler roller. I was surpirsed to see that these rollers use plain bearings, not ball bearings.
5. On the front support piece, drilled out the rivets for the glides, and replaced the worn out glides with new parts. Applied a little glue (3M weatherstrip adhesive) to the cork pieces, to glue them to the metal. Attached the plastic pieces over the cork pieces, and riveted in place using rivets that came with the glide kits.
6. Replaced front and rear felt seals. This was not as tricky as I expected it to be. They were held in by metal tabs. Glued the ends where they came together.
7. Replaced the felt blower seal. Glued to the blower housing.
8. Reinstalled the drum, installed new belt, which came with good instructions (luckily).
9. Reassembled front support piece and the front of the cabinet.

I also cleaned the lint from the cabinet and from the vent hose.

In general, the job went without a hitch, and the machine probably has quite a few years left, despite the fact that it's 18 years old. This gives me a good feeling.

I'd say this would be challenging, though, for someone who is not pretty experienced with machinery repair. Also, the cost of the parts was significant enough that it would not have been unreasonable to have opted for a new machine.

The dryer was so old (33 years) that the customer service woman could not find the model number. However, she gave me the oldest Maytag model lint filter number she had and she had me compare online a parts drawing of it with mine. It looked so similar that I took a chance and ordered it. And it fits perfectly. She gave me excellent customer service. I regret that I did not record her name.

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.

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 searched the internet and found my symptoms really seemed to indicate a problem with the blower wheel, which was very noisy. Feeling confident that was what I needed, I ordered the blower wheel, and also the tumbler belt (the belt was 12 years old). Both parts were genuine Maytag and arrived quickly. Before the order arrived, I went ahead and UNPLUGGED THE DRYER and disassembled the dryer using the partselect.com helpful parts diagrams and the repair notes of others. This allowed me to confirm the blower wheel was in fact loose on the motor shaft. I removed the old blower wheel and belt. Shop vac'd out the entire dryer cabinet. This way I was able to take my time with preparation, and when the new parts arrived, I was ready to just pop them into place. If you disassemble before you order, you can also determine if the tumbler front guide set and /or rear tumbler roller wheels also need to be replaced (mine did not), but this would have been the perfect time to replace those too. I saved a bunch of money and have the satisfaction of having done this job myself. Dryer works great now.

1: Disconnected all water and electrical connections.
2: Removed front panel.
3: Disconnected all wires leading from the control panel and removed the top of the washer.
4: Removed the springs that holds the drum down on the damper pads.
5: Flipped washer upside-down so the drum would hang from the bottom of the wash. This made it easy to clean the area since it was full of dirt and ground metal dust.
6: Glued new pads (per the instructions) to the cone that protrudes up from the bottom of the washer and allowed to dry.
7: Lubricated the pads with the provided grease and added additional silicon grease to insure smooth operation.
8: Replaced drive belt.
9: Flipped the washer back up-right and installed the drum springs.
10: Reconnected all wires and attached the top of the washer.
11: Reconnected all electrical and water lines and tested operation.
12: Replaced the front panel.

Washer now runs as quite and smooth as it did when it was new.

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.

To see if the lid switch was the problem I first jumped it out and tried to start the washer. That was the problem. I removed the main controll so I could get to the lid switch. I made the mistake of removing the screws all the way out and the metal clip fell into the body of the washer, no problem since I was changing the drive beld anyway. I realized that you do not remove the screws all the way out, you just have to loosen them and then slide out the lid switch & then replace it.

First found out where the belts were by tipping the machine backwards and saw that the belts were intact but extremely loose. Ordered two belts (Drive and Pump) . Re-tipped the machine and in less than three minutes, had installed the new belts. I re-hooked the hoses to the back and the machine operated as if new.
