I searched before making the thread…
Anyways, is it possible to fix our heater resistor or replace those crappy coils with better resistors? Wouldn’t it just be a matter of measuring the resistance of the coils on a good heater resistor, and replacing with better resistors of the same ohm-rating? Has this been done and did it work?
Just speculating, but it seems like it should be possible to put together some resistors to do the job of the blower motor resistor coils. The question is: would it be reliable and would it last? The engineers who designed that part designed it that way for a reason. Notice the placement of resistor coils; they’re placed in the blower motor housing so they will have airflow going over them. Those coils must generate a fair amount of heat that must be dissipated. Would regular resistors be able to shed heat sufficiently to be able to avoid burning out? I have no idea. If you have a bunch of resistors, give it a try. Really, though, I’m not sure it’s worth the trouble. What does the coil pack cost? $35? They do eventually burn out, but not very often. Just my $0.02.
Isn’t there high-heat resistors out there? Made of and/or coated in ceramic or hardening-tar or something?
