Question:

How do I remove the old hi-limit thermostat and replace it with this one?

Answer:

Hello Gillis, one side of the hi-limit goes onto the heater terminal and the other connects to the wire. Replace the old one on the heater leg with the new one. Best of luck with this repair.

Question:

Can I test this with a multi-meter? If so how will I know if it is still in good condition?

Ed
Answer:

Hi Ed, yes, this high-limit thermostat can be tested with a multi-meter tool, and should read closed for continuity. Please let us know if you have any further questions.

Question:

My dryer is not working properly when I have it on “auto dry” but every other setting seems to work. You recommended first to check the vents and the blower but those are all in good condition and no clogging, where should I go to next? Would it be the hi-limit thermo?

Aaron
Answer:

Hello Aaron, the most likely reason for the dryer to not have heat, would be a damaged contact in the timer. I hope this helps!

Machine was in need of new thermostats

I did my repair alone by myself after viewing a short video online at partselect.com The man in the video showed every step slowly and professionally. I took some extra time to clean the dust off behind the back of Dryer while I had it open for fixing.....thanks for your help and it saved me over $190 plus which I was quoted by technician for estimate and parts. I paid $43.00 for my parts...both High limit and Cycling thermostats were replaced. My wife told me good job honey ! You can do it too.

Clothes coming out damp, after a 60 min cycle

1. Unplug unit, next disconnect vent then remove back cover. 2. replaced element (very easy) then 2 thermostats, then put cover back on. 3. Removed frt. cover by following directions that came with maint. kit this too was easy. The hardest part is getting belt on as your putting drum back in, and even that was only so hard. Just TAKE YOUR TIME, and you will get it.

No heat in dryer and lint filter torn

Dryer didn't heat. I got the heating element thru sears and when I ordered it I thought I should also order the thermostats but I didn't. Element arrived two days after ordered right on time. Slipped right in in a few minutes. Turned dryer on. No heat. Went back to drawing board. Watched videos on part select site and realized I needed thermostats. Ordered them and lint filter. Arrived right on schedule and also slipped in in no time flat. Turned dryer on and yes it heated perfectly. Wife was pretty impressed with new lint filter as other one was torn with jagged edges. MY SUGGESTION: if your dryer doesn't heat and you can't test each individual item thermostats and heating element order the three of them ( high limit and cycling thermostats and heating element) cause they'll probably will all go at the same time anyway. Then won't have to wait on the second shipment if things don't work with partial replacement. Parts select was great and videos are well understood and easy to follow. Would certainly use again.

Dryer was cutting off before time

I watched the installation video and learned that the installation was a very easy job to do. I followed the instructions and indeed the job was really easy. Requiring only a 1/4" socket and a Phillips tip screwdriver.

Dryer would not heat.

Used the trouble shooting tips provided as a guide and a multimeter to test and find the defective part. Testing indicated no continuity thru the high limit thermostat. I ordered the part and received it in 3 days. Had the repair done a full week before the repairman could even come to the house and saved well over $100 in repair costs and 2 weeks or longer of down time. Great website and service.

Dryer loads took repeated cycles to dry a normal sized load of laundry.

Researched causes of low heat and purchased thermostat and heating element. Delivery was less than one week. Installation was easy with the on-line video.

Dryer too hot in all heat settings.

My dryer was running way too hot and the temperature settings didn't make any difference. Clothes were shrinking and coming out almost scalding hot. I followed simple directions posted on you tube for troubleshooting this problem. I checked that there were no lint blockages, visually inspected all connections and hardware. All seemed good. Metered out all thermostats and fuses. Everything checked good for continuity. For the reset-able thermostats, I heated them on a hot plate to verify that the normally closed switches opened near their specified temperatures. Dont do this for the non-resetable fuses and thermostats. If you're
not sure, avoid this step. Only the hi-limit thermostat seemed to open a little higher than expected but I couldn't with 100% accuracy determine the exact temp it opened. Made sure the heating element wasn't shorted in its housing or that too might give the dryer the same symptoms. That checked good too. Only thing left I could think of was to change that hi-limit thermostat. Ordered part, removed and replaced. Perfect fit. Op-checked good. All heat settings now operate normally. No more shrunken clothes that are too hot to touch even on the lowest setting lol. Hope this helps, happy hunting.

Low heat, too long to dry, seal loose and deformed

Thermostats go right in after removing the back. Drum felt seal manufacturer's written instructions and diagram were not clear. The projecting part in the middle of the felt needs to cover the rear drum edge to prevent metal-to-metal contact of the spinning drum with the rear inside bulkhead. The PartSelect video that shows this cannot be viewed in my web browser, Chrome. User the Explorer browser to be able to see the videos to see how to do it. The front panel screw boltclips were loose. Tape them in place before repositioning the front panel. The time to repair included letting the seal adhesive/glue dry. Let it dry completely outdoors since it is stinky.

Dryer would not heat on any heat settings.

First I watched the repair video on-line at this site After pulling the dryer away from the wall and unplugging the 220 volt power cord I removed the back panel with the 9 screws. I then unplugged the wires to the thermostat/heating element. With an ohm meter I discovered that the heating element was good and the high limit thermostat was bad. I ordered the high limit thermostat from this site on a 2 day shipment. When the part arrived I installed the part and the wires. Plugged in the dryer for a quick check for heating. Replaced the back panel and moved the dryer back into position. Dryer works fine now.

The dryer would not heat up

I unplugged the machine and removed the back panel with a 1/4" socket. I unplugged each thermostat in turn and pulled them out. The internal bias was a bit tricky to remove without breaking the tabs or wires. I then placed each thermostat back in and replaced all the wires. Not bad at all. Weird thing is the dryer heats just fine now, until I put the back panel on; once I replace the back panel, it will not heat.
