If you turn thermostat to fan On instead of auto will fan come on? Also do you have a multi meter for troubleshooting?

no the fan does not come on and I do not have a multi meter
HVAC Technician: airheatman, HVAC Technician replied 2 months ago

We would need a meter to troubleshoot. If you have a meter let me know .If not you can get an inexpensive one at Walmart for about 15 bucks if you would like to troubleshoot and I would be happy to guide you.

I will not get a multi meter if I am only going to use it once will you please try to direct me on this matter?
HVAC Technician: airheatman, HVAC Technician replied 2 months ago

Without a meter about all you can do is look at the capacitor and see if it looks puffy or is leaking and that fan wires are all connected.

If those are ok, the issue is either a bad control board (Not sending power to motor) or a bad fan motor.

Since we can not "see" electricity, you can invest 15 bucks in a meter to troubleshoot, invest 100 bucks in calling a technician with a meter or start replacing parts. The motor is a couple of hundred as is control board.

Which would you like to do?
