i have a whirlpool le2500xtw1 dryer, i bought used.it worked fine for about a month, then one day it would run but not heat. first thing i did was get a new element. but the problem was the thermal fuse was blown. the replacement package had a new thermostat as well as the fuse. after a few days of drying the thermal fuse has blown again. could this just be a short in the wiring somewhere.

Anything that results in the heat staying in the heater box will cause this. Many possibilities, including loads too large, lint screen not cleaned after each load, shorted heater, restricted or kinked exhaust vent system, inoperative exhaust hood, etc. I'm curious why you replaced the dryer you used to have? Also, did you install both parts from the cutoff kit?

i didn't have a washer/dryer in my apt., moved into a house and needed one. i bought one from a used appliance store that was recommended to me by a few people. the dryer came with a 30 day warranty. it worked fine until a week after the warranty expired, then it quit drying, but still would turn. i replaced the element, thermostat, and the thermal fuse. and after a few days it quit heating again. i taped the wires together from the thermal fuse and the element would get hot. i have some knowledge of electrical workings, and i am pretty mechanically inclined, i would like to try to fix the machine instead of replacing it. this is the first time i have done any work on a dryer, other than replacing a drum belt. any helpful tips will be appreciated and used.

If the heater box thermal cutoff is open, that means that the heat that the heater creates is staying in the heater box instead of being moved through the dryer and out the exhaust. That means you have an airflow issue or a shorted heating element. Since you have replaced the heating element, that leaves an airflow issue. Unless you have been stuffing the drum, the load sizes are ok. Make sure you're cleaning the lint screen after or before every load, make sure the vent between the dryer and the wall is not kinked and is as short and direct as possible. Then make sure the vent from the wall to the outside is clear and unobstructed and that the flap(s) outside are free to move with the airflow coming out. These issues by far the most common culprits to this problem. Check them all and you will most likely find the problem. If you can't find anything wrong with those things, make sure the felt seal at the rear of the drum is sealing to the bulkhead all the way around the drum's edge.
