Heating, Air Conditioning, Fridge, HVAC/outside blower motor not coming on automatically

Question
My outside blower motor will not come on unless I hold the contactor switch in manually.  The switch does not stay engaged or on and of course blower motor does not stay on.  Does that indicate the contactor is bad? AC blows cold and heat works as well. Please advise. Thanks John

Answer
J P ,

Outside blower motor would indicate you have a packaged one piece unit . What contactor are you talking about ,the blower relay or the compressor contractor ? . If you put the fan switch at the thermostat to on the indoor blower should run 24/7 . Again I do not know exactly what your asking. Is this a Heat Pump ? You would need to have a meter to check to see if you have low voltage at the contactor coil to determine if it's bad or just lack of voltage at the coil
