How to troubleshoot Nortron Furnace that will not turn on?
If your Nortron Furnace won't turn on, check the thermostat, circuit breaker, or fuse. Also, inspect the CONTINUOUS VENTILATION switch, bottom sequencer, and transformer.
Why is my Nortron 21B10M not producing enough heat?
If your Nortron Furnace isn't producing enough heat, potential causes include defective elements or sequencers, the SEASON SELECT switch being set to the MILD position, safety limits opening due to duct obstruction or dirty filters restricting airflow, a defective or incorrectly wired two-stage or outdoor thermostat, or a lack of enough cold air returns in the house.
Why does the motor in my Nortron 21B10M run continuously?
If the motor in your Nortron Furnace runs continuously, check if the CONTINUOUS VENTILATION switch is not on the OFF position, if the thermostat wires are incorrectly attached, the bottom sequencer, or the 24 V Relay.
Why does the breaker on the front panel of Nortron 21B10M Furnace trip?
The breaker on the front panel of your Nortron Furnace trips due to overcurrent on the heating element. Reset the breaker. If the problem continues, it's recommended to call an electrician.
Why is the motor in Nortron Furnace going on and off in short cycles?
If the motor in your Nortron Furnace is cycling on and off too frequently or infrequently, the heat anticipator in the thermostat may be incorrectly set or defective.
Why the thermostat must be set much higher than desired temperature in Nortron Furnace?
