Why heater fan will not come on?


Wish I knew how old your furnace is. Let me answer your question directly. In the heat mode the fan runs independently from the air conditioning fan relay. Its either brought on by time or temperature. An old furnace will use a fan and limit control that uses a coil to sense the heat exchanger temperature and turn the fan on or off. Newer furnaces use a timer on a circuit board. 20 years or newer Ill bet its a timer board. Follow the blower motor wires back to the component and ill bet that's the culprit. Hope it helps. Good luck.

Sounds to me like it is going off on a weak high limit switch. With the fan on it will prolong the event but will not stop it. I would check all of the high limit switches. It would most likely be one close to the heat exchanger.

Fan will come on for heat(auto), but not for AC or set to ON


You have a blower relay in the furnace that's probably bad. In the heat mode the blower is on a temperature relay, in cooling mode the blower has to come on immediately so there is another relay for cooling. The green wire on the thermostat feeds that relay, so if you go to the furnace and shut the power off and find the green wire from the thermostat that feeds that relay and replace it, being careful to mark all the wires before removing them, also the relay terminals have numbers for identification.

Blower fan will not come on when set on Auto in heat mode.


the fan is controlled by a fan center or a stack switch. as burners light and heat up the spring sensor on the bulkhead above burners heats up and turns and a a point energizes the indoor fan if it gets to hot the burners go out on safty. sounds like a fan control is bad tap on them gently and they sometimes break loose but if not then have a pro replace fan control and test heat exchanger.

I had the same set and problem. I had a RC wire which is the power to the AC. But didn't have an RH wire which is the power for the heat. To fix this just use the jumper wire and insert it in with the RC wire and hook it up to the RH. Fixed my problem.
