SG9900 Maytag Washer Dryer Combo - Instructions

I tested the dryer coils and found that they were getting a voltage but would not open the gas valve. Coils were not bad but weak. After they warmed up they would not open the gas valve. It took 10 min to repace both coils and the heat sensor.

Remove top two front cover screws. Disconnect wiring. Set aside front cover - door assembly.

Remove two screws at top of the vertical riser cover to expose entire dryer interior. Remove filter. Remove screws to blower cover plate. Remove 4 screws that fasten front drum guide assembly. Remove drum. remove and replace 2 drum support rollers . Replace one rusted drum roller shaft. Replace both drum rollers and non-metalic washers.

Drill out 4 rivets holding two front drum glides. Replace and rerivet new drum glides.

Pry back slighty the many retention points around the front drum assembly which hold the front drum felt seal. Refit the new front drum felt, pressing the retaining clips back in place with a screwdriver.

Replace tumbler motor belt.

Install Drum. Install front drum retention assembly. Install new blower seal with reassembly of blower cover.

Total time - about 1 hour

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

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!

Unplug the dryer and remove the front panel (two screws at bottom of the panel), being careful of the door switch wires attached to the front panel. Using an ohm meter, I checked the ignitor for continuity and found it was open (should be 50-100 ohms). Make sure to check the solenoids on the gas valve. When the igniter goes bad, it will usually burn out the valve 1 solenoid boost coil (the one with 3 terminals), which was the case with my dryer. The solenoid coils are held in by a bracket with two screws (series 01 dryer) and are easy to remove and replace. Be careful replacing the igniter as the heating element is VERY fragile. Take the time to vacuum out all of the accumulated lint and dust inside the dryer while the front panel is removed, including the lint trap and duct. New igniter and boost/hold solenoid fixed the problem.

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.

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.
