Clicking sound is the contactor engaging to start the outside unit. Check for a burnt off wire at the contactor. For some reason you are not getting power to the outside unit. If you find a burnt off wire shut off all power to it then remake the connection at the point of the circuit break.

SOURCE: central heat and air system won't shut off

sounds like tstat is wired wrong or possibly the contactor relay has fused shut outside. if you can stop the system from running at the tsat it is usually a problem with the t-stat
if you cannot shut off the outside unit without turning off the power at a breaker than usually the contact relay needs replacement

SOURCE: Ruud Achiever 10 heat pump - outside fan won't shut off

Definately get this checked out. Some thing has shorted just enough to let voltage "Feed back" and keep the fan running. Could be capacitor, wires rubbed through each other, etc. A reset is a safety that is used when there is an overcurrent or over pressure situation. No reset set for this situation.
There is always an outside chance that if you touch the unit while standing on wet ground, you may get shocked. I firmly believe that something is allowing power to the fan in a feedback condition so don't let this go as it may cause damage to other parts.

Good Luck and let me know how you make out on this.

SOURCE: Thermostat will not turn on AC unit or the fan in

Here is what I would try to see if the thermostat is bad. Take the facing off the thermostat. Once this is done you will see where the wiring is connected should be a red green yellow and white Turn off power to unit make a diagram as to where the wiring was connected red to r green to g and so on Remove these wires red green and yellow and twist them together Go to the power source and re energize the unit once this is done all components should come on if not the thermostat isn't your problem Red is your low voltage power supply (24 volts) Green is your fan motor in furnance, yellow is your outside cooling unit. 1 other thing you might check. In the furnance if the doors are not properly installed on the face of the furnance it may not allow the unit to come on. There is a safety switch on the furnance where the filter is that if the door is not put on properly the whole system loses power and will not work. Hope this helps. Good Luck

I have a duotherm AC unit. Which two wires do I jump to bypass the thermostat


Hey David if you are wanting to bypass the thermostat to make the air conditioner come on you would take r which should be red and y which should be yellow,. Tie them together. This gives the outside unit a constant 24volts( call for cool). If it is a heat pump you would also want to take o which mostly is orange and tie them with the red and yellow to energize reversing valve. If not it will be jumped out but be in heat mode. R to w(white) would turn your heat strips on. If your thermostat is bad and you plan on leaving it like this temporarily also take g (green) and tie it to red and yellow. G is your inside fan. Basically r is your 24volts so you tie it to what u want to jump out y= outside unit o/b=reveesingvalve if heat pump g= inside blower w{ inside heat strips. C is common never jump c to r or you will blow a fuse or transformer only reason you would have c at thermostat is so it can run without batteries. Hope this helps

Payne AC not working. 1. Thermostat set 68 to AC w/fan on. 2. Breakers and switch near heater are on. 3. Outside unit has 220v but is not running. 4. Fan in heater/Ac unit is not running 5. ...


Dan is this a new system, or has some work on the system (to include the thermostat) been done recently?

Sounds like the thermostat may be wired wrong. From what you describe, the igniter element is coming on, as though you are calling for heating. Do you allow the ignitor to keep going and see if the gas fires off, or are you seeing this and shutting down the system immediately?

If you had the t-stat changed recently, or this is a new system, contact the installing contractor. It may be under warranty.

I have a Trane heat pump, model #TWP060C300A and a Trane air handler, model #TWE065E130A. Heat pump is 5.0 ton, split system. Air handler has a variable speed motor and a 20Kw 3-phase auxiliary heat strip....


Honeywell Chronotherm thermostats have always had a great reputation for longevity and reliability. They are also much more user-friendly than the other types of programmable thermostats out there. Make sure you get one that states 2-stage heat, heat pump. T8611G will offer that for you. There are many out there that claim to be suitable for heat pumps; however, they do not have the ability to utilize your auxiliary heat strips (2nd stage of heat).
Before you attempt to replace, be sure to write the wire colors and their corresponding terminal marking on a sheet of paper........of your old thermostat. This is very important to make it easier to hook up the new thermostat. Also, before you disconnect the wires, be sure to shut off the circuit breaker to your air handling unit. You can ensure you have the right one by putting the fan switch in "ON". When you turn off the right breaker, the fan will stop running. :-)

I hope you find this information to be very helpful to you. Please don't forget to leave a rating.

Fan does not turn off even after disconnecting


Are you referring to the fan on the external mechanism, or the internal air handling fan?
The external fan is not controlled by the internal thermostat. it is controlled by the thermos-witch of the compressor. The external fan may or may not run when the motor is operating. it depend totally on the temperature of teh compressor, and not the internal thermostat.
It the internal air handling fan is running continuously,it may be a a problem with the fan setting. check if the fan is set to 'ON' instead of 'AUTO', and correct it.
Incidentally the fan operation I described, is for modern, energy efficient heat systems. This is a energy saving design incorporated in all heating systems including automobile radiator fans.

Carrier 38CKC042300. oUTSIDE UNIT FAN WAS TURNING REAL SLOW. ac UNIT IS OFF BUT FAN TO OUTSIDE UNIT IS STILL TURNING. sHOULD NOT BE TURNING AT ALL WITH AC UNIT OFF


The outside fan may run if the unit is in defrost mode this is normal for most heat pumps it is there way of trying to keep the outside unit from staying iced over so the next time the unit runs it will have air flow through the coil and the ice will not be there to prevent air flow.

My air handler comes on ,not the outside unit when my thermostat is in the off position even if i turn the thermostat down to 50 and have it turned off the air handler comes on for about 5 to 10 minutes...


If you have a standard thermostat the fan switch is for the air handler only. It completely over rides the thermostat for most settings. Now lets see this is what I'd expect:
fan switch on Indoor fan runs all time
Fan switch auto Indoor fan only runs when thermostat is set to cool or heat and the thermostat is turned up above room temp for heat or below room temp for cooling. In both of these modes the furnace blower comes on and stays on til the room temperature is satisfied. The outdoor unit only comes on for AC the out door unit will not come on for heat or the "on" setting on the thermostat. See exception 1 & 2 below...

Exception 1- (in a heat pump the out door unit runs in both heat and cool mode unless it has emergency heat turned on then it will not come on outside in the heat mode, and depending on the type of heat pump and furnace or air handler it is). A heat pump thermostat usually has "backup heat" and an "emergency heat" setting switch on the thermostat.
Exception 2 - On some thermostats they are made to cycle on the heat if the temperature reaches a preset temp (around 50'f usually but definitely by 40'f). This mode prevents freezing when if instance the homeowner is away or while the home is under construction. In this mode the fan inside can run but the heat usually comes on with it.
Exception3 - On some electric furnaces the heating strips may be individually controlled and thus not all come on at one time. This may give the feel of no heat especially if the room is cold.

Now there may be other exceptions but Ive tried to give you a heads up on some of the most common ones.
If you need more help please post more specifics about your unit/system as to for sure what switches are set to what setting and what is happening with each. My first though was that maybe your system is OK and you needed to know if the thermostat was working properly.

If this helpd you understand your problem would you please give me as hifgh a mark as you can. Thnaks for using fixya and good luck.

Intermittent heat


It sounds like the unit has lost its first stage of Heat (It uses the outside unit to bring heat in with freon) When the thermostat is put 3deg higher than room temp it uses Heat Pump and heat strips, this is probably the only time yours heats. Have it checked as you will pay a lot on next month's electric bill.
