I am having problems with my Nortron Electric Furnace. Sometimes when the thermostat tell it to come on in the heating cycle, it does and other times it doesn't. When the furnace doesn't come on, if I run the fan on continuous from the thermostat it seems to heat the house ok. When the furnace is in AC mode, it works fine cooling the house. I am lost as to which relay is bad. Any help would be appreciated.
