I replaced the heating element a year ago and now the replacement is broken. Both elements had an open and did not short. Could the element get overheated? Would replacing the thermostat fix this? Thanks
Answer Hello John,
This can be due to a sticking thermostat but is more commonly caused by a ducting issue that is holding the high temperatures in the unit too long. If the ducting is clear, (no clogs or crimps), and is as short and straight as possible, you should still replace any of the ducting that is flexible since all of the major manufacturers have determined that this is a major cause of issues. Normally replacing the thermostats will not help when the issue is a heating element failing unless taking the units' average operating temperature shows the thermostats not opening.
