Question about Ruud UBHC Air Conditioner
The thermostat LED shows the heat is suppose to be running (little fan rotating in the lower left hand corner). However it is not. I have to keep turning the thermostat off and back to heat in order for the heat to come on. When it comes on, runs for a few minutes and shuts down before reaching the set temp. I have changed the batteries and still the same problem. Anyone help with this problem?
Problem is not the thermostat, thermostat is an on-off switch that happens to work on temperature. Your furnace is locking out. cycling the heat off switch resets the micro-processor in the furnace. You need to diagnose the problem in the furnace, to go further we will need the model and approximate age of the unit
