My father asked me to post this. He has read through and tried the fixes mentioned in other posts, but the dryer still gets hot and blows the thermal fuse.

Here's what he's done:
  • Cleaned out the entire system, including all vents and hoses
  • Replaced the temperature control
  • Replaced the heating element
  • Replaced all the thermostats
What can he try next to get this fixed?

Hi,

I got 110.66712694 to work for me.

Here's what he's done:

Cleaned out the entire system, including all vents and hoses - Dryer ducts also?
Replaced the temperature control - On the consol?...why?
Replaced the heating element - Was it bad/grounded?
Replaced all the thermostats - Usually only concerned with the operating thermostat which is on the fan blower housing.

but the dryer still gets hot and blows the thermal fuse.
Right away, after 1 load, after 6 loads, after a week?

Drum seals been checked, fan blower been checked, ducts inside the dryer been checked, lint filter been checked? ( air flow issues )

Dryer ducts also? Yes.

One the consol? Yes. why? It was the next thing to do since the other fixes didn't work. Plus, the ohm reading was outside of specs.

Was it bad/grounded? Did not appear to be.

Usually only concerned with the operating thermostat which is on the fan blower housing. Replaced the one in the fan blower housing, too.

Right away, after 1 load, after 6 loads, after a week? It happens during the first load. The heating element never shuts off (doesn't cycle).

Drum seals been checked, fan blower been checked, ducts inside the dryer been checked, lint filter been checked? Drum seals seem good (no excess air), blower checked fine, ducts taken apart and cleaned, lint filter cleaned with soap and water.

A copy:

I was on a service call and found this problem...even after I suggested the customer check the venting/dryer air ducts/lint filter before we look at the dryer. "Everything is good" is what they told me..... guess again.....this is what I found.....

It happens during the first load. The heating element never shuts off (doesn't cycle).
That concerns me....not shutting off could be a bad new part ( that operating thermostat ), a wiring issue ( shorted or melted wire ), poor air flow and we are simply not drawing the heat from the element area into the dryer.

Have you tried a load with the vent pipe disconnected from the dryer as a test?

Some no name fuses are crap also...
