Carrier thermostat Hello, My Carrier electronic thermostat is connected to a heat pump.  It was set to the COOL position during a summer thunderstorm when the AC suddenly began running no matter what the SET temperature was.  It works normally when I change it to the AUTO position.  The HEAT and EHEAT positions work normally. I tried cutting power to the unit for 2 days, after which it worked normally even on COOL, but after a short power failure it resumed the problem of running the AC continuo


I hate to say it but Ive had trouble with Carrier's Tstats doing similar improper things. Unfortunatly the only repair is going to be replacement of the whole tstat. I recommend Honeywell's FocusPRO or VisionPRO tstat. Ive yet to have one fail and th ... Air Conditioners

I have a duo-therm thermostat that I think is the problem. My a/c only works when the fan is swithced to the on position but does not work in the auto position, also the heater does not come on and work unless i tie a jumper line to the ground wire. I have been told that the problem could be the thermostat or the circuit board in the a/c. If I can I would replace the thermostat with a digital.

I have a problem with my central heat / air unit. As it is getting cold now, I am using the heat. My problem is that I must turn the thermostat to the on position to get the unit to come on. In the auto mode, nothing happens. I can get very cold but not ever kick on until I move the switch to the on position. In the on position it works fine. Thinking that my problem was with the wall thermostat, I replaced that. I do not remember having this problem with the A/C. What should I look for to fix t

Goodman GSH130301AB heat pump with Braeburn 1200 multi-stage thermostat - both less than 1 year old and installed in new construction. Heat can be set at 60, fan on AUTO, with room temp at 70 and heat will kick on and stay on. When this happens, turning thermostat to OFF does nothing - system continues to blow heat - and I can only shut it off by flipping the breaker. This only happens now and then - typically works fine.

There is a switch on my 1 1/2 ton Ruud furnace/Air handler that is not working properly. The unit would not turn on, even though the thermostat was working. I took the panel off of the air handler and found that a switch had been duct taped into the on position on the unit. Apparently, the tape had shifted and the switch was no longer in proper position. when i moved the switch, two green indicator lights lit up. When i turned the unit back on, the A/C worked. Clearly, there is a problem w

This is a heating and cooling through the wall heat pump. It works normally when heating is selected - the heat pump runs and both speeds of the fan blow warm air. But nothing runs when cooling is selected. In other words the unit works normally when "High Heat" or "Low Heat" is selected but nothing runs when "High Cool", "Low Cool" or "Fan Only" is selected. The position of the Fan Cycle Switch has no effect - behavior of the unit is the same in both positions of the Fan Cycle Switch.
