Does fan motor run. Can you turn thermostat to on position and get fan to run. Russ

Customer: replied 1 year ago.
motor runs, furnace works ok and maintains temperature it is set for. but fan keeps going on and off until temp is reached
sometimes running for a few seconds then off then back on and so on. probably not thermostat because a/c works ok on same
thermostat.
