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

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
