How to fix a dryer problem on a Haier wd combo

Dear Bob,
The answer may be easy, but the implementation?
Daunting!
About 20 years ago, two things happened to dryers.
One, "robots" began making them, and
Two, they became much more subject to overheating, as the automation caused more problems with lint build-up and subsequent overheating.
To combat the overheating danger of fire, more thermostats and even a fuse or two were then added.
I suggest you completely dis-assemble the dryer and you should find lint build-up inside the ductwork that is inside the machine that is blowing out the thermostat or a fuse.
A good cleaning should fix it for a year or two, depending on how often you use the machine.
God bless your efforts.
