Part Description: The thermal cut-off kit prevents the dryer from overheating if the high limit thermostat fails.
Failure Symptoms: Dryer will not heat at all, or takes an increasing amount of time to dry your clothes.
Testing: Use a multimeter to test it for continuity in the fuse and thermostat. If there is no continuity in either piece, it should be replaced.
Bonus Tip: A blown thermal fuse indicates a restriction in the exhaust vent that runs from the dryer to the outside. Be sure to check the dryer venting whenever you need to replace the thermal fuse.

Great Price!
Local parts store didn't have this as a set or didn't know enough to sell it to me. I got 3x different fuses atvthe lical store all of which were on my dryer. The problem was that my dryer has a 4th one, which is the high limit fuse that goes at the top of the heat vent. I replaced the two with this set and will return the 3x parts to the local store. I really would like to support my local store, but at those prices, they better get me squared away the first time, which they didn't. Glad I found this kit frim Thrifty.

Excellent Service/Delivery!
This was exactly the part we needed without having to get a whole kit and saved us a considerable amount of money and waste. It was delivered much more swiftly than we anticipated getting it. Consequently we got our dryer up and running much sooner and didn't have to make a trip back to the laundry mat again so THANK YOU!

Parts on time
I purchased a Whirlpool dryer limit thermostat and fuse kit. All I needed was the fuse, but the kit was so inexpensive, I just replaced both parts. This kit was 1/4 the cost at Thrifty, compared to other sites. The best part was that the kit showed up 2 days ahead of their predicted arrival time.
