Replace furnace

Damper motor for that zone could be bad or thermostat for that zone could be bad

Rescue motors don't come with capacitors. You have to buy it seperatley it should say on the motor box what size cap the motor will need two brown wires

Replacing the flame sensor won't fix your problem. Does your furnace have a circuit board? Does the gas valve have 24 volts across it as it drops out if so replace valve. If 24 volts drops out as flame drops out replace control board. Make sure rollout switches aren't opening.

Make sure flame sensor is also clean/polished with some sand paper until shiny chrome

It doesn't matter if its just two wires either way will work the same

Sounds like a relay in the circuit board is going out might need to replace board

Do you only have one thermostat either upstairs or down. If so you might want to look into a zoning system where a thermostat would be added so you would have both floors controlled by dampers in the ducts. Can be kinda expensive but it would solve your problem
