Follow the wires back from the motor to either the relay or the circuit board. normally a furnace has a board. check to see if there is any power leaving relay/board to the mtr. if it is a furnace you may need to push in the door saftey switch to get power to system. heat pump mtrs need 230 vlts furnaces 115vlts. If the power is going through to mtr properly than problem is either capacitor or mtr. capacitor can be checked for you by a local hvac supplier or buy a meter that can check it.
PLEASE rate or solution thanks. Brian S.
if you do as i suggested it will let you know the problem it takes my about 30 seconds to trouble shoot this problem when i show up.
you can bypass the relay for now. if you take the wire sending high voltage to the relay and the one to the moter cut off the spade connectors(buy some to replace these and wire nut them together the blower should run constantly which will let your heater cycle on and off till you get the relay. make sure to turn the power off! first please!
