SG7800 Maytag Washer Dryer Combo - Instructions

I unplugged the dryer,removed the two small screws on the front of the dryer and pulled the bottom forward. The two wires connected to the door do not have to be removed. With an electrical tester using the Ohm setting I tested the Radiant sensor and the Gas Valve coils. The two terminal coil was DOA. The dryer can be operated with the front open as long as the door wires are connected. Symptons: The igniter would heat up and not release gas. My repair was successfull due to this awesome website and the super fast shipping service. AAAA++++

Replaced the 2 belts according to instructions received with the belts. Very easy repair

Found a very stretched, loose pump belt. Was able to pull it off pump pulley and motor pulley easily. Pushed motor assembly toward transmission pulley and removed wider drive belt. Wiped all pulleys clean. There's a double on the motor- one for drive belt, one for pump belt. Removed two hoses from pump using nutdriver. Removed pump. New pump installed. Installed two hoses on new pump. Installed drive new drive belt. Installed pump belt last. Slid pump to near farthest spot in slots. Tested for correct tension by pinching pump belt. Should be able to pinch center so two pump belt sides come within 1/4" of each other just as the spring tensioned motor mount starts to move. Pused washer back into place after external hoses connected. All new hose washers and filters on both hot and cold. Ran, checked for leaks - none! Absolutely perfect. Put front panel back on. No weird noises and drum empties perfectly every time. My wife is so pleased she's doing more loads.

Used toothpick for a year to push switch acctuator far enough to engage switch. Broke my foot and found time to order part thru PartSelect. Went from cast to boot and received part 2 days after ordered. Had difficulty with foot and getting to switch. Went back into PartSelect and figured out how to dis-assemmble panels thru the diagrams. Time on my job doesn't, just that their service and expertise that is available to everyone is there to use. Broken bones or not, I will always get my parts and advice from PartSelect. Thanks to PartSelect.

I opened the panel, undid the plugs, detached the radiant sensor by undoing one screw and removed and replaced the part. Fairly simply.

I was told that it might be a clog in the tube.. we check the tubes that wasn't it Then I Google it and was told it might be the drain pump. I was just glad that Part Select had what I need because my machine is over 20 years old. We change the pump and now I hope I get at least another 20 years out of my machine. I will always use part select to get my parts. Thanks

The dryer was not getting hot the clothes we're damp and had to put on hangers to finish drying. I pulled the cover plate saw the element was glowing the gas cable would kick on had a flame for about a four to six second count. I did some checking on the web. I read about others who were having same type of problem. Order the limit part and now.the flame stays on for about twenty second or less the dryer gets hot and it drys fast. Thanks for the web site. It took about thirty minutes . Now it works great.

Turned off circuit breaker. Removed two screws at base of front panel with stubby Phillips-head screwdriver. Swung panel up about 30-degrees, and removed panel, disconnecting red and yellow wire to door switch. Removed four sheet metal screws and took off large drum support bracket. Checked drum support rollers and shafts. They were fine. Reset circuit breaker and turned on dryer. Rattling noise still present.
Removed six small screws holding blower fan assembly. Shaft receiver on squirrel cage fan was worn completely round (it should fit onto a half-round shaft). Ordered new blower fan from PartSelect.com. Replaced tonight, and it works beautifully. This dryer is 29-years old. All it's ever needed in the 10-years I've owned it is a belt replacement and this repair. Long live the 1970s Maytags, and good parts suppliers like this one.

Pulled the big front panel by removing two screws near bottom of front and pulling out at bottom until the top pops loose. Vacuumed out all of the dust and checked for loose connections. Ran dryer - igniter would light, but no gas. Checked the two solenoids with a VOM. the one with the two leads would intermittently read Infinity (open). Super simple repair. Remove two screws on solenoid bracket on top of the gas valve, Replace solenoid and plug it back in with the easy push-on connector. NO PROBLEM - all fixed.

Removed the screws and took the door off then took the front panel off and popped up the top. Then pulled the drum out. Took snap ring pliers and removed rollers and replaced with new rollers then vacuumed all lint from machine and reversed operation to put everything back together. Operation was a total success!

Unplugged power cord then disconnected the water supply and drain hose. Removed 2 screws and took the front panel off. Laid washer on it's side and posistioned the transmission with the cover facing upward. Removed the hex head screws then used a razor knife and a putty knife to remove the silicone sealant. Found that the agitator shaft spring had broken and fallen into the housing jamming the gears that's used in agitation. Removed the oil and all broken pieces of the spring. Installed new shaft spring, replaced the oil then applied sealant to the cover and screwed the cover back down. Let the washer stay in the same posistion for about 18 hours to let sealant dry completely. Then I sat the washer back on it's feet and removed 2 screws that holds the top lid in place. This allowed me access to the tub cover where the injector t is located. Installed the injector t along with the injector tube seal. Connected the hose and hose clamp. Then I put the lid back down and secured with the screws. Connected the water supply and drain hose then the power and selected a wash time and observed the operation. Everything worked ok so I put the front cover back on. Note: I had used the injector t from this washer to fix another washer that an appliance dealer had given me to use for parts to repair the one just described above. That was the only thing that was wrong with it. It was used for about a year and a half and it developed a problem in the spin cycle. Appears to be a brake problem. I intend to repair it as well.

I deduced the lid switch was the problem.

I removed the two screws holding the control panel on. Pulled the control panel back.
Disconnected the ground wire of the lid switch.
removed the two top clamps that hold the panel to the top of the machine.
Pulled back the casing (outside of the washer) and placed it on it's side on the floor. Here I could reach the switch. Removed old, installed new and reversed the process.

The part that gave me the biggest problem was setting the casing back on to the frame. You have to slide the front part in at the bottome, then lean back the rest of it.

Determined the tub seal was bad and ordered the seal and tub bearing. Removed the front cover with two phillips screws and unbolted the top to lift back. Removed the agitator with 1/4" setscrew on side and lifted out. Using punch and hammer, broke the inner tub nut loose (clockwise is off). Lifted out the inner tub, unscrewed springs from the bottom and removed; then removed the bearing with a little prying (had to raise the tub slightly and tap the center splined shaft to push out) and lifted out the outer tub. Outer tub had few rust spots about to penetrate, so sanded off rust, primed with etching auto primer and sprayed enamel topcoat to prevent further corrosion. Reassembled in the same order.

When done, there was still a loud noise on the spin cycle, so obtained a spin bearing and brake assembly (need to replace both most always). Tilted the machine on its back and removed the pulley, then put a special wrench on the brake assembly and broke loose (counterclockwise) with a 3 foot extension after placing a 2x4 section in the tub between wall and one of the bases for the spring arms (to keep the tub from turning). When the brake came off it was full of water and corroded from the leaking tub bearing previously replaced. Reassembled in reverse order and replaced two belts on the bottom for good measure. Works perfectly now and is very quiet.

In my estimation, the repair should have included both the tub bearing/seal and the spin bearing/brake assy from the outset. Could have used a chain visegrip wrench instead of special tool to remove the brake assy - whatever is available. The tool costs a lot and will never be used again.

Put blocks under the washer where the leveling leg was needed and screwed the part into the washer. Then it was just a matter of moving the washer into place and leveling. Pretty easy.

** Your best bet is to use a digital camera to take pictures of the various stages as you take apart the dryer - especially the wiring. And, use masking tape to label all the wires.
** I removed the Blower Housing which made the process much easier.
** Find a friend with or buy the snap ring pliers
** Big Secret not mentioned anywhere - the Motor Support (diag. #20) can be removed ! Hence - the entire Motor assembly can be taken out to remove those irascible Motor Clips.
** For the Green ground wire going from the dryer frame to the motor, you need to take the screw from the old motor and use it to screw into a hole marked with a black "slash" on the new motor.
** After 3 days of WD 40 and an allen wrench, I could not remove the Motor Pully from the old motor, so I would buy one if I were you.
** Hardest Parts - Removing the Motor Clips, reattaching the idler spring!, having another person hold the drum while I installed the Belt and reattached the front drum frame thingy, and deciphering my wiring schematic and reassembly diagrams ! That is why a digital camera is so helpful.
** The process is really very easy if you use the suggestions above and read the others.
** Find the "Model Diagram" on the PartSelect website - an excellent resource !!
** A twenty+ year old Maytag - up and running again !! Many thanks to others who shared their story.
