Hunter 44860 says heat is running

Does the indoor blower come on when you switch the unit to "Fan/ Run"? If the indoor fan comes on, this verifies that you have both low voltage and high voltage to the unit. If not, you may have one or both voltages giving you a problem. Try this and let's see if we can get it going. This is step one in checking it out.

Good luck and hope this helps

I set temp to 74 and stop at 70 and decresing.

The only thing I can think of other than being just old and worn out is that by design it may not be set to run but so much at a time. Has this always done this since you have had it? It may be needing calibration. One thing you can try is to set it at 2 degrees higher than you want it and then it would shut off at the temp you actually want.

Air and heat have both been running on Hunter 44155C

There should be a switch on the thermostat.
And another switch
Normally, you just set it for heat or AC and set the fan for auto. If it isn't wired correctly, the switches won't make any difference. It will either run all of the time or not at all.

blue to y assuming

  • R: It is the main transformer low voltage wire. It comes off of the transformer and feeds to the thermostat.

  • Y: It is the compressor wire and is connected to the other side of the compressor.

  • G: It is for fan. It is connected to one side of the fan relay and there is a common wire on the other side.

  • W: It is for strip heat. The strip heat has a relay and common side. The wire is connected to the other side.

    44860 thermostat won't activate in heat mode

    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.
