LSG7800AAW Maytag Washer Dryer Combo - Instructions

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.

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.

** 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.

I want to mention only the difficult parts.
The removal of the retaining ring/nut (which is under the agitator) . After 10 + years, it was very hard to move this part and it was eventually broke it to remove it. WD40 was used but not effective (to much calicum build up). You must turn the cone shaped piece (located under the inner tub) clock wise to get it to remove. A spanner wrench was not used to remove this. I used a punch and a tack hammer. We could not remove the old tub bearing (closest to the shaft), so we just cleaned it up with emory cloth and used the new tub seal/outer bearing. Spins great but have not been able to check the water leakage problem yet.
Caution: there are two dark colored ring (very thin) that go back on top of the rubber collar. These must be reused. These are hard to see. I pushed the old tub seal/bearing out with the end of a 2x4 (very slowly and carefully). I put the tub up on two of the 2x4's, for clearance off of the floor and used the third to knock the old bearing out. Old machine are very messy.

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.

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.

removed old pully, put new one on with hex driver, removed belts, put new belts on and finished.

After replacing all the other fuses and sensors I finally replaced the Radiant Flame Sensor and it is working perfectly.

After replacing the other parts and the heat still not coming on I read somewhere that the Radiant Flame Sensor is a normal closed circuit and when I checked with a meter it was open. I would have saved a lot of time and money if I had read that earlier.

I removed the front panel of the dryer by removing the 2 screw that secure it at the bottom and pulling upward to disconnect the cover at the top. I then removed the two screws that hold the metal cover that secures the 2 elements in place. I disconnected the wire plugs from the 2 elements, removed the 2 elements and replaced them with the new parts making sure to place them in the same positions as before. I then replaced the housing cover and tightened the screws. Then I replaced the front cover of the dryer.

My washer filled up and wouldn't drain at all.

I tried checking the fuses, then read that the belt could be broken or worn. I checked under the hood and the belt was broken right in two. I drained the washer manually then ordered the new belt.

I was able to replace the belt in no time with no effort at all.

I followed the supplied directions to remove covers, unbolt tub springs, and expose the area needed to replace the damper pads. I cleaned the area with acetone and applied a rubber adhesive (not supplied). I used tire patch compound because that is what I had on-hand. I positioned the pads and after they had dried 1/2 hour, lubricated them with the supplied grease. I reassembled the washer and it is now smooth and well behaved.

First I unplugged the machine. I removed the two screws in the front panel and tilted the bottom of the panel out unclipping it at the top. I removed the lint duct whichis held in place with several 1/4" hex head screws. Then I removed the blower cover, also held on wth 1/4" hex head screws, exposing the blower wheel. Using snap ring pliers I removed the snap ring at the end of the motor shaft. Using needle nose liers I removed the spring clamp around the center hub of the old blower wheel and pull the blower wheel off the motor shaft. After cleaning as much lint out as I could I put the new blower wheel on the motor, secured with spring clamp and snap ring. Then I put the blower cover and lint duct back on and put front panel back on.

Went on the PartSelect website, input the problem, and got the Water Inlet Valve as the diagnosis. When the part arrived, I viewed the short video on replacing the Water Inlet Valve and just followed the instructions. It could not have been easier. After turning off both the hot and cold water and pulling the plug from the wall socket, I removed the screw holding the bracket and valve to the machine; removed the 2 screws holding the valve to the bracket; removed the wire harness ends from each solenoid on the valve; replaced the valve with the new one and reattached the wire harness, followed by reattaching the bracket to the valve, and assembling to the machine.

replace lint filter under agitator, remove 1 screw, lift out agitator and replace filter screen.

My 20 year old reliable Maytag 512 lgp dryer was not heating anymore. At first the heating element would glow red but not hot enough to ignite the gas. I replaced the element and it worked for a few loads but then stopped reigniting after the first cycle.

After some research and diagnosis (checking connections, amperage flow on each electriical part, etc.) I determined that the two coils were faulty. I ordered parts and replaced them (easy to do) and it worked again, for another few loads. Then nothing worked. The coil did not get hot and I did not hear the clicking sound that initiates current flow to the ignitor through the coils.

I checked the coils and ignitor again, they were fine. Frustrated, I called in a repairman to diagnose the problem. $55 and 15 min later he narrowed it down to the High Limit Thermostat. To demonstrate he bypassed the thermostat by directly connecting the two leads together and the ignitor fired right up.

His price to replace the thermostat? $45 part plus $130 labor. I bought the thermostat online for less than half his parts cost and the labor took me 5 minutes. Simply unscrew the small screws with a small socket set or nutdriver and replace the thermostat. Just two connectors, real simple.

All in all it was very easy to replace the parts, just tricky to diagnose unless you are good with electrical work.
