I have a Hunter Thermostat model 44260. When heat turns off, fan keeps on running. I have flipped the HG-HE switch on the back and that temporarily works. However, once the heat kicks back on again and then off the fan fails to stop. How do I fix this problem? Thanks.

Re: Hunter Thermostat fan won't turn off
Hi and welcome to FixYa,
Initially, I am inclined to suspect 3 possibilities:
sticking relay contacts (if used) (a possibility, least likely);
dusty thermal sensor/switch for the fan (likely);
time delay. design feature, will power down the fan only after a certain period that the heater has turned off. This is to dissipate residual heat not only on the heater but on the immediate surroundings of the heater element (most likely).

Here is some basic info to help you. On the thermostat the letters mean... G is for your blower fan, and is usually green, Rc and Rh are power for the heating and cooling circuit (24v) and are usually red; Y (or in this case Y/O) is power to the cooling contactor (outside the house) and is usually yellow, and W (or in this case W/B) is the common wire, and is usually white. It kind of sounds like the people who installed the old thermostat followed these guidelines, so your best chance is to go to the heating unit and seeing where the wires connect to. Hope this helps
you have to replace the thermostat . problems like this are common with latest electronic thermostats from china . most are going bad in less than 4 years . it so bad ,i am telling anyone who asks , to please keep there old regular thermostat , or if you have one of the old electronic ones (made over 10 years ago) hold on to it , it will last forever.... somehow when we moved the factory to china they forgot how to make thermostats that last ........ if you plan to rate this answer , please rate it 3 or 4 stars . this will help me stay in the paid answer department
On my Hunter model, there is a "Span" setting that allows you to change how long the AC/Heat will run before it turns off. Basically, it sets the acceptable range (above and below) your temperature setting. To access this press both the up and down arrows and hold them. "Span" should show up with a number (1,2, or 3). For your problem, change the setting to 1 so the AC will run shorter, and more frequently to keep the temperature more constant.
I have a manual thermostat with the following wire connections (Y, G, R, O, C, & E) with the respective wires attached (yellow, green, red, orange, blue, white). My 44260 has available G, Rc, Rh, Y/O, W/B, Y1. Which wires should I connect to which terminals on the 44160. Thanks.
Here is a link that will have wiring diagram it is for a similar model hunter. Also check your dip switch on the back of the stat to ensure it is set for gas (HG) or electric heat (HE) depending on your type of unit. Good Luck. Rule of thumb for most four wire systems is RED (power to stat) Yellow (Cooling) Green (Fan) White (heat)
Do you have gas or electric. Remove the stat from it base and look on the back you should see a switch marked HE and HG. HE is electric and HG is gas if you do not have it set correctly the heat will not function.
