8640 - Instructions

first I went online and took a look at the schematic and realized that two items can shut the complete unit down and would be easy to check. First I checked the door switch with a multimeter then the high limit non-resettable thermostat. The contacts on the thermostat were open which told me it was bad. Went online to www.partselect.co ... Read more m and found the part really easily. came in when they said it would and it was a perfect match to the original (part numbers on the side and eveything). Make sure you correct the problem that caused the unit to overheat in the first place. IN my case the dryer air passages were full of lint. After a good cleaning put it all back together and it worked better than it has in years.

Replaced the thermal shut off and the thermistor located on the heating element bracket.
Easy to diagnose and to replace- not totally accessable but not that bad either. Cleaned out lint obstruction causing the problem.

After reading everyone else's comments I started by pulling out the dryer, unplugging the power and exhaust. Next moved the dryer to an area where I had room to lay it on the back. Then using a flat blade screw driver, I popped the top attached tape to the top so I could lean back the top without having to hold it. Removed the two sc ... Read more rews from the front panel and removed the door safety shut off before removed the front panel. Then I layed the dryer on its back. Then reached under the drum, pushed the belt tensioner toward the motor puller to release the tension on the belt. Then slid the belt to the base. Pulled the drum up and out of the cabinet. Next I cleaned all the lint and crud out of the dryer components. To remove the clips that hold the rollers in place, I use 2 small flat blade screw drivers. These are inserted at the back side of the horse show shaped clip between the shaft and the clip. When the two screw drivers are rotated like turning a screw they slide the clip out. Next I used a socket wrench with a #8 metric socket(I didn't have the sae size) and removed the screws holding the drum roller brackets. I simply reversed the procedure to install the new rollers. Since the dryer was on its back, when I put the drum back in, its own weight slipped it in place. Then pulled the belt around the drum and between the motor pulley and the belt tensioner. Holding the belt with one hand, I used the other hand to pushed the belt tensioner in and positioned the belt. Then I stood the unit back upright and put the front cover on, replaced the door safety switch, removing the tape holding the lid and then cloed the lid. Of course I put the dryer back in place, leveled it, and it now runs like brand new. My thanks to every one else who gave me hints that saved be about $450!

1- cleared all the ducts. (They were clogged and this is what caused the fuse to open)
2- Replaced the fuse from the kit
3- The dryer stopped working again after 1/2 hour -the fuse blew-up again
4- Altough the stat (the other part included in the kit) checked OK with the multimeter, it was actually defective and did not re ... Read more gulate the temp.
5- changed both parts included in the kit, the dryer worked normally again.

Thanks to reports from others, I concluded that most likely the gas ignition coils (one or both) were no longer functioning properly. I replaced both with the 'M' Series New Style Coil Kit which is about 1/2 the price of either coil individually -- yes,true,go figure! The actual replacement took only about 10 minutes. What was most diff ... Read more icult and took the most time was the removal of the front panel of the cabinet -- this was difficult only because there were no instructions in my owner's manual (or any other source I could find) and it took me awhile to figure it out. Now I could do the whole job in about 20 minutes! The detailed instructions from others as to the process of replacing the coils was invaluable -- I don't know if I would have been able to figure that out on my own. But most important was the information that enabled me to diagnose the problem in the first place. Thank you, all you previous comment contributors.

I first made sure there was power to dryer. It was ok so I unpluged the dryer from the socket and afer researching on line I was sure it was the thermal fuse. I check continuity on the fuse and it did not have continuity. So I installed a new fuse and high temp thermostat (they come together)
Just lift top of dryer up and back. I ... Read more n the left rear corner is the heating element. On top of the element is the thermostat. On the right side is the fuse it is a round disc with two white wires attached. The thermostat and heating element need to be removed to install fuse (one screw each and lift out of the way ) . Need to check for blocked lint or like I had the white plastic hose had a kink and need replaced with metal lint hose.

I watched the video tape

Pulled the old seal off then pushed the new one in place.

i followed part select instructions that probable cause was either thermal fuse or high limit thermostat.put ohm meter across both & saw thermal fuse(has pink dot on it) part 53-1182 was open.ordered thermal fuse replacement kit. part#LA-1053. the problem i had was after reaching down the side of heating housing removing the bracket with ... Read more the thermal fuse,replacing & reconnecting it i had a hard time reinstalling the bracket,very tight space & i don't have very big hands.finally got the fuse in it's hole in the bracket & slid & jammed the bracket into the side of the mounting housing & it stayed secure.dryer started

Vacuum out the dryer vent & trap of all the tenant's sleeping bag stuffing, intall the new lint trap and Voila! It works again.

I took apart the dryer by unscrewing the top and the front, front comes off by just undoing the two top screws on the inside. I figured it was something to do with the rollers since the noise was ciclycal. The hardest part was to put the drive belt back on. It helps to have a second person for about 5 minutes.

I just removed 1 screw that held the safety thermostat in and replaced it. Then I removed the long screw that holds the heating element and the high limit fuse in place. Replaced the fuse, cleaned out the lint duct area. Closed the dryer lid and pluged it in, it worked fine.

Lifted top from dryer and fuses were in the back of drum just below heating coil. Used nut driver to remove heating coil to gain access to fuses and replaced them. Process was quick and easy. Diagram from this site made locating fuses elementary!

P.S. I have no certified experience in appliance repair.This was my first time ... Read more ever and dryer works perfect.

After watching the great install video, I followed his lead and within 20 min had my dryer door fixed. This dryer was bought in 1986 and I really thought I was looking at buying a new dryer. How wonderful that I could fix it for less than $11. Easy to find web site, easy to find part, great instructions and fast delivery!

Lint filter replacement is routine maintenance. operating without a filter causes problems, a dryer sheet was sucked thru the opening and into the blower wheel, causing a lot of noise, and shaking because of the unbalance.

Removed the offending sheet, straighted the bent fin, and put everything back together again. Installeed the new filter, now it runs smooth, and quiet. mission accomplished.
