Try turning your thermostat from fan auto to fan manual, if the blower starts then you have a burned out speed on the heat leg.

If this is true, shut power off to furnace and try and trace out the blower motor wires. Usually they will
gto to a terminal block that is marked heat/cool.
Just reverse the connections

Heil heat pump heat won't work changed defrost board ac works


Reversing valve may be bad or stuck. U can pull the fan, then turn the unit on. The reversing valve is just a small unit with a 110 V. cable going to it. Sometimes taping the valve will make it change to heat.if so it will need to be replaced.

Heil epm36f19a1 runs but no heat


Fan relay is stuck among other things. The thermostat turns on the combustion air fan and puts power to the spark unit. If the burner comes on after the temperature in the heat exchanger rises the indoor fan will then come on. After the thermostat comes to temperature the power to the gas valve which shuts off the burner. Then after the heat exchanger cools a bit the indoor fan will stop. That's the sequence of events. look at the switches that control the fans. There is a wiring diagram somewhere on one of the panels that access the unit for service.

HEIL HVAC, fan blows but no heat or AC


Your airconditioning system may be out of cooling gas, and if it has sufficient gas, the compressor might not pick when you put on the AC, and if the compressor did not pick ie start, you cant experience cooling effect, the fan will only be blowing.

The outside unit is not working on my Heil Air conditioner


The attic fan is not a part of your a/c system, and you should not run it while you are running the a/c. If you are currently using the attic fan, it is possible that someone wired it so that the a/c won't turn on while the attic fan is on. Otherwise if the thermostat is set below room temp, and says it is calling for cool, then the problem is most likely coming from an issue at the outside unit itself. Make sure to check your fuses, at the fuse panel and outside breaker. Hope this helps

FYI.. the only part of the system that might use batteries is the thermostat.

Heil Max Performance 10 Heat Pump not working


First check to see if you have afloat switch inside the air handler ar underneath the air handler. Its purpose is to shut the outside ac off if the drain stops up. Very common. If this is OK take cover off unit and with screw driver push in the contactor. It is located about the middle of the panel. It has main power at the bottom. If unit comes on you cave a control voltage problem. Meaning something is not allowing 24 volts to the contactor. If your out of Refrigerant the low pressure swich will have it off. Call a service tech. Rusty
