Question about Carrier 36KCARMS Air Conditioner

1 Answer

I have a new Carrier HVAC system with a fancy EDGE thermostat. When I turn the system OFF at the thermostat, and set the fan to AUTO, hours later I will find that the fan is running and it's setting on the thermostat is now ON. How can I permanently turn off the fan when the system is off?

    Thanks. I understand and this indeed will turn the fan OFF.
    However, it's too bad this has to be done. I like the fact that I can program the fan to run when the thermostat is not calling for heat or cooling when in those modes. But the thermostat should turn off the fan altogether when one turns the system to off; without having to go through this programming exercise each time.
    Someone at Carrier wasn't thinking when they designed this thermostat. During the summer, I routinely turn the HVAC system off when it's not needed. This should shut everything off and not require a programming change.

1. Open the door. 2. Press and hold the buttons underneath the heat and cool setpoints simultaneously (the two bottom buttons on the right) until the screen displays the reset reminders and 01 in the lower right corner. 3. Press the up arrow button until 01 changes to 07 with OF (fan mode) next to it. 4. To turn the fan on, press the rightmost lower button then press the up arrow button until the screen displays ON. To turn the fan off, press the rightmost lower button then press the down arrow button until the screen displays OF (off). 5. Press the done button. 6. Close the door.

    Using the hold feature should work for this.

I have Carrier thermostat that we lost manual for. Model is 960-060170-30-R. We are trying to get the fan from permantly running to auto position. Any help would be great or a link to the manual


I believe that is the edge tstat and what Im finding is you can only control the fan when your not running a program. if you have occupied and unoccupied settings it may be under a business program rather than residential. Google the edge manual and follow steps to remove the programming. Good Luck!!

Need a quick fix for a Carrier that won't heat. Ac works, fan works, auto for heat doesn't.


Could be the capacitor or the heating element (or igniter if it's a gas unit). Unless you're a qualified HVAC repairman, call your local HVAC company to come take a look at it.

I have a Carrier Weathermaker SX HVAC unit with a Honeywell thermostat. Even if the thermostat is turned "off", my fan keeps blowing!


Hello, usually this is a sign of a bad blower relay on the intergrated control board. The only option is to replace the control board.

Have installed a new Honeywell thermostat. The fan does not turn off even when the room has reached the desired temperature. I originally replaced th ethermostat because the old one the fan ran forever and...


Most T-Stats have a On / Auto on a forced air system. On means the fan will run all the time even if it is not calling for heat. Auto only runs when calling for heat. Does the fan turn off in the auto mode at all? To test it...BE SURE THE FAN IS IN THE AUTO MODE ON THE T-STAT... Turn the thermostat all the way down and keep it there for appox 15 mins. If it is wired properly and the fan limit is set properly the fan should turn off. If it doesn't it is not the thermostat were the problem lies.

Most forced air units have a fan / high limit switch. There is a setting on the switch for the fan to turn on and a setting for the fan to turn off or it has a setting and a differental switch for it to turn off/on. Example - the fan comes on when the temp in the heat exchanger reaches 110 degrees F and will shut down at 95 degrees F after the thermostat is satified...this would hav a differental of 15 degrees F. It may be set to low and the fan continues to run long after all of the heat has been removed from the heat exchanger. This in turn will cause cool air to be coming out of the registers.

Outside unit runs continuously, even when system is off.


On A/C units, there is a low voltage line that leads to a contactor, which engages to close the high voltage circuit to the condensor unit. Over time, the accual contacts in the contactor can weld themselves together. Try shutting off your furnace breaker but leaving on the one for the outside condensor unit. If it still runs, your contactor probably needs replaced. Contact a licensed electrician or HVAC contractor and tell them you think your contactor is in need of replacement. Is a fairly simple and quick replace, but the contactor itself is not cheap.

Are you a qualified refridgerator mechanic with an eletrical liscence? If not get someone who is because doing it yourself will not only void the warranty of the unit but will also void your house and contense insurance in the event of a fire.
