Hvac Heat Will Not Turn Off at Jerry Bergman blog

Hvac Heat Will Not Turn Off. There are a couple potential reasons why your heating system won’t turn off: If your furnace fan won’t turn off, your thermostat may need to be switched to auto, the limit switch may be in manual mode, and there may be faulty wiring or switches. The short answer is your furnace won’t turn off due to some kind of error or malfunction within your furnace, thermostat, or hvac system. A faulty thermostat can normally be repaired. If your furnace won’t turn off, you should look at the thermostat, the air filters, stuck buttons/switches, leaking air ducts, a faulty blower motor, or issues with the electrical sensors. A clogged furnace filter can cause a furnace to shut off. Dust and dirt restrict airflow—and if the filter gets too clogged, the heat exchanger will overheat and shut off too quickly, and your house won’t warm up. Dirty filters are the most common cause of furnace problems. You should make sure a manual override has not been programmed, and take a look at the limit switch that controls the fan. One of the leading reasons your thermostat can't shut your hvac unit off is that it cannot read the right temperature.
