Should the fan be set to on or auto?
Keeping your fan on AUTO is the most energy-efficient option. The fan only runs when the system is on and not continuously. There is better dehumidification in your home during the summer months. When your fan is set to AUTO, moisture from cold cooling coils can drip and be drained outside.
What is your preferred minimum fan runtime?
The minimum fan runtime is a setting available on your Ecobee Thermostat that allows you to choose how long you want your HVAC fan to run between heating or cooling cycles. This can be set from 0 to 55 minutes every hour, with 0 meaning that your fan will remain off until the next heating or cooling cycle begins.

Is the blower motor the same as the fan control AMP?
Our version (at least for the auto control AC) is the Y33. The metal housing looks different, but the circuit board is the same with the same value components. In short, the blower motor is mounted in series with the fan control amp. The auto AC regulates the fan control amp, which regulates the voltage to the blower motor.
How do you set the fan speed on an air handler?
Inside the air handler, usually on a control board (a printed circuit board) there will be one or more switches or little jumpers that the service technician can set to control the fan speed or speeds on the particular air handler. It’s usually a switch or jumper change, or occasionally on older air handlers, moving a wire from one pin to another.
What is the fan setting on a HVAC system?

How do you set the fan limit on a furnace?

Why does my blower fan not come on in auto mode?
Everything goes as it should except when time for blower fan to come on. It doesn’t come on if in “auto” mode but if I put it in the “on” mode, the blower comes on and I have heat. I replaced the limit switch L170-40 and still have the same problem. There is another limit switch in the blower area L140-40.

When does the HVAC blower fan come on?
Interestingly, we discovered fan comes on when system is on “Heat” and fan is on “auto”. Things I’ve checked and tried: Tested motor by testing common wire to each of the speed wires (High, Med, Low), all showed about 7-10 ohms
