I have a 13 year old furnace. The blower is not kicking on, however the electric ignition is working and lighting. I am wondering if this could be the thermocouple, or the blower motor?

Yesterday morning I noticed that the thermostat was blank. I assured it had gone bad. I replaced it but the AC still would not come on. I went downstairs and the furnace was making a buzzing noice. I took the cover off and replaced a small fuse but still nothing. Help please

My furnace is running and putting out heat. However, my thermostat temperature is not rising, so my furnace runs continuously. Does anyone know why this would be? Is my honeywell wall unit going bad on me? The thermostat is only about 2 years old and my quietside furnace is only about 2 years old....

I have a burnham gas furnace (baseboard hot water heat) . Three zones each with Taco zone valves/heads. Three sepearate Honeywell thermostats. Problem occurred with only one zone. The upstairs was heating way past what thermostat was set at. Even after turning thermostat down all the way,...

I noticed that my thermostat works fine and opens the zone valve for the basement. The problem is that it won't send a signal to the furnace to turn on and heat the water. I have no problem with the upstairs zone valve. It opens and turns on the furnace. Is this a wiring issue? Thanks...
