Thank you for your response, Glen!

And they say this based on what? Did they do a voltage check at the dryer?
Yes, they had a friend with a multimeter check the voltage at the outlet. Of course, when I make it out there, I will check as well, but for now I’ll trust their findings.

So would a service tech.
But you need keep in mind that even a service man
would not necessarily have every part on hand that could cause
the trouble this person is having. Most only keep some of the
faster moving parts on hand. There are a whole slew of things
that could keep the dryer from running at all, but you are certainly
not going to want to spend the money to have all of those items
with you. The answer to your earlier question is "yes" the thermofuse
could very well be bad. However if so, there is a reason it went out.
They don’t simply go out on their own. The reason could be anything
from excess lint to restrictive venting or a bad thermostat.
Given the distance I would check to see if there is a place in that
area who sells appliance parts. If not I would recommend referring them to
a service man who would carry many of the fast moving parts with
him in stock.
An area service man is entirely out of the question. Times are just too hard, and they cannot afford that on their fixed income. In fact, I only found out about the dryer failing because I called one day and heard all this noise in the telephone. When I asked what it was, I was devastated to find that she was hanging their clothes up on a clothes line outside and had given up on the dryer altogether.
Since I do all the work on my own appliances and vehicles, and service home/auto HVAC systems in my free time (certified), I figured I’d get it running for them and would also clean their lint exhaust lines of any obstructions. Plus, it’s been raining all week, so the clothes line idea just is too sad. At any rate, I just wanted insight from you awesome professionals because I have no wiring diagrams or service manuals to reference.
So given the information I provided, could the thermal fuse blow on the Whirlpool LER5644EQ1 dryer and still allow power to reach the timer BUT somehow cause the buzzer not to sound when the timer’s placed at the end of a cycle and the start button pressed? I was under the impression that the thermal fuse only cuts off power to the heating element since most motors have their own circuit breaker that would prevent overheating. I further am guessing that the "Push-to-start" relay is the only thing that would prevent starting -and- keep the buzzer from buzzing when the "Push-to-start" button is pressed with timer at end of cycle.
Again, these are all just educated guesses, so if anyone has a wiring diagram for this model, I’d really appreciate it. Or even if you could just look at it and tell me what all is protected by the thermal fuse circuit, particularly the push-to-start switch/relay and buzzer. Also, does anyone have a PDF of the service manual?
TIA again!
