Sounds like the batteries are in backwards. Or they are no good.

    Possibly a bad tstat. Turn power off to unit. Remove red and green wires from inside tstat and twist or wire nut together. Turn power on. If fan inside comes on and runs, tstat is bad.

I have a honeywell focus pro 6000 temp in house doesnt change unit runs constatly. thermostat says 78 thermomiter on other end of house says 72. changed batteries


It's possible you have a lot of dust build up inside the stat. If it has batteries remove face from wall and blow out. Take outside to see if temp will change. Plug the hole in the wall where the wire comes through. If all fails, replace. Turn power off, take wiring picture, replace, turn power on. Good Luck!!

If this is a system with the thermostat separate from the unit itself, check the batteries. NO batteries, then check the jumped red wire on the thermostat sub-base, which is under the face plate. Gently pry it apart.

The buttons on my air conditioner quit working. It will still turn on and off. It is now set to fan. Will a universal remote work with it? I don't want to spend $75 on a remote(replacement remote) that...


I'm not sure there is a universal remote available for AC units. There may be, I just have not seen one. However, you can still operate the unit without the remote, if you do the following. I'm assuming you have changed the batteries in the remote and they were installed properly (i.e. Facing the right direction) and it still doesn't work or you lost the remote.

Turn the unit OFF and unplug it for 15 minutes. Once the time has elapsed, plug the unit back in and turn the ON/OFF switch to ON. The unit should have reverted back to the original factory setup settings. Which should now allow you to operate the unit without the remote, because the controls on the unit should now be activated.

I hope this helped you and thanks for choosing FixYa.

Thermostat is on but fan will not turn on and no heat pump or back up propane heater either.


Is the thermostat battery powered? If it is it sounds like the transformer may be out on your unit. If you have a volt meter, remove the face of the thermostat and check for 24vac between R and C or R and Y or R and G terminals. If you don't have it, check the circuit breaker for the air handler or for any blown fuses. If you can't find anything there check for power with the voltmeter on the primary side of the transformer and on the secondary side. If you have power on the primary and no secondary you need a transformer.

Take a multimeter and check your rh and w terminals. With the face off, you should get 24 volts. If you do not get 24 volts, turn the power off, and check the continuity, you should get ol (open load). Now if you do not have 24 volts, and the meter reads ol, there is a problem in the wiring to the thermostat. My only concern is the green light blinking slowly, but if that is normal on your unit, I will let it be. Hope this helps

Problem with my Airtron Thermostat


Two things, first go up to the heater and check the fuse inside the heater, looks like a car fuse. If that is not popped, then go outside to your AC unit and pull out the emergency disconnect. Check those fuses with a multimeter. IF you do not get anything replace those fuses, It has nothing at all to do with your thermostat.
