Can't turn HVAC fan off
 

My house, like most in the Villages, comes with the Ecobee thermostat. I turned off my system, and it's confirmed with the message "no equipment running'. But the fan is still running. When i went to the fan setting, it only has an 'on' and 'auto' setting, no 'off'. In the 'auto' setting, you can set minimum run time. I set mine to '0 minutes/hour' which is the lowest setting possible. But my fan keeps running. What do i need to do to turn the fan off?

I followed the instructions here but it did not help:

I suggest that you verify that the smart recovery setting is disabled for both heating and cooling. Also, turn off the circuit breaker and then turn it back on.

On the thermostat:
Select Main Menu > Settings > Preferences
Select Heating Smart Recovery or Cooling Smart Recovery.
Touch Enable or Disable.

Yes, Turn the Circuit Breaker off ! If the fan is still running after the breaker is on , it may be your Thermostat…

Has happen to us plus 3 others we know. In one case the fan wouldn’t come on, rest of us fan would run constant. We all have Carrier units.
The components that control the fan are located in the fan motor end cap. The individual parts cannot be replaced. The entire fan end cap must be replaced. Probably still under mfg warranty? Labor is your cost unless you have a service contract. Your cost about $150 range for labor. We used Munns.

How often does the fan come on and for how long? I had the same issue with my new carrier equipment and ecobee thermostat. I also set the fan's minimum run time to zero and it STILL came on. However, it's only for about 5 minutes twice an hour, so I am just living with it, as it's only the fan, not the condensor that's running and the fan is at least ciruculating the air inside the house.

New Ecobee was replaced after six months. Terrible product. No need for complicated product for simple task

Just had my fan controller replaced by Munns. It was also running continuously. It was under warranty.

I found the Ecobee much better than those Carrier thermostats that they put in North of 44.

I’ve had one for four years. Not one issue or problem

Yet?

My new carrier comfort unit has dumb Honeywell thermostat. I don’t like my stuff to be smarter than me.:)

Nope. Four years is a good run for not one single issue. But like anything else, something can always go wrong.

I agree with that! It's got to be the most complicated household appliance I've ever seen!

I disabled the smart recovery. Fan kept running.
I then turned off the circuit breakers. There are 2: one is labeled A/C, the other A/H. When I turned off the A/C breaker, fan kept running. When I turned off the A/H breaker, the fan went off. Fan came back on when I turned on the A/H breaker again.

The only other thing I can suggest is to do a factoy reset on your thermostat. If that doesn't work, then I don't think the problem is with the thermostat. Here are the instructions. Good luck.
