Question about Coleman Heating & Cooling
Hi, if you have no power to the stat, go to the furnace if this is a split system. Depending on the year you have, this unit may have the main circuit board with a 3 to 5 amp control fuse plugged into it. If this is what you have, check this fuse, it is the same as the fuses in your car. If you don't have this circuit board, locate the transformer where your thermostat wires come in and check for power at both the 120 volt primary side ( power in ) and see if you have 24 volts coming out of the secondary side of it. If no power in, check the circuit breaker to the furnace. If there is power in and nothing out, the transformer is gone. Check close for any breaks in the stat wires at the furnace also. I may need to have the model and serial numbers, and if its a split gas fired or a heat-pump unit if this information does not apply to your unit. Let me know.
