there should be a diagnostic code that will tell you what 3 blinks mean for that model. look on door inside cover. tell me EXACTLY what it does at start up. small draft motor comes on? you see a glow from hot surface ignighter? gas comes on? flame on? it should run in this order.

the motor may have too much play as indication of worn bearings,
and besides, the capacitor may be bad, the cause for not startng up, oil.

If you are hearing humming from the motor itself, replace the capacitor. Should only cost you $10-20.

To rule out a faulty thermostat perform a jump test on the control board. There's a lot of videos and tutorials online for performing a jump test. I attached one of them for your reference, however with the humming, I am inclined to believe it is a faulty capacitor.

Try changing out the start up and run capacitors for the compressor.

If it's tripping, you've got a short, probably water where it doesn't belong. Unplug and inspect the unit. Hopefully you'll find a bad or missing seal.

i don't know. it may be your blower or your motor that needs to be inspecvted. be very careful. shut off power to furnace. turn thermostat to lowest setting. shut off circuit breaker for furnace or remove fuse for furnace. open blower panel; and pull drive belt [ i f furnace has one ]
that turns the blower. if it turns, the blower is OK i suspect the motor needs repair. https://www.repairclinic.com/RepairHelp/Furnace-Repair/36-383--/Coleman-Furnace-Troubleshooting
