Why does air conditioning start to smell when the compressor turns off but the fan keeps running?
The coil gets wet from condensation but when the compressor is running the air is cold so it’s ability to absorb water is very low. When the compressor turns off the air heats back up, absorbs the water from the coil and blows the humid air out of the vents.
Why is my AC fan not turning off?

Can a fan be turned on and off at the same time?
The fan in your AC system can run separately from the cooling component of your AC. These two parts work together to cool your home, but don’t always turn on and off at the same time.
Why does my air conditioner keep running when the thermostat is off?
Usually when the relay switch is broken, the fan will continue to run by itself. This happens because there’s no communication between the thermostat and the blower fan. Now, if it’s a short circuit, both the ‘ on ’ and ‘ off ’ commands you enter typically won’t get sent to the blower fan. As a result, the blower fan will continue to run.
When do you turn on your HVAC fan?
Your HVAC fan should turn on and off with the rest of your heating and cooling system. It’s normal for the fan to kick on a couple of minutes before heating starts or to stay on for a couple of minutes after cooling stops, but your fan shouldn’t run for hours on its own.

When does the air circulation fan shut off?
From the beginning, the outside unit (compressor) would shutdown after about 45 minutes of running, but the air circulation fan would continue to run. We have the original thermostat also which blinks a code and according to the manuals we got withthe system, there must be either a timer or temperature shutoff on the compressor to protect it.
