I am a homeowner who tries to DIY as much as possible. Today I noticed that my Carrier AC unit was not cooling and the blower was continuously running. After checking the evaporator coils and drip pan for water buildup, I checked the outside unit for frost buildup. Nothing found. I then turned the unit on and heard the humming of the fan motor for the outside condenser coils. The fan was not rotating and the motor felt hot. I shut it off to let it cool down, then turned it back on and assisted the motor to turn by pushing the blades with a long stick. The motor started to turn slowly, then picked up speed. Although it continued to turn, it did so at a slower speed, never building up to capacity.
So, my question is - could the issue be with the start capacitor or both the capacitor and the motor? I don't know if this unit has a start/run capacitor, or just a start capacitor. Should I bite the bullet and just call in an HVAC pro? I just looked on line and priced the replacement motor for about $175 US plus shipping. I don't know what a capacitor would cost, maybe $10 to 20 US. Any recommendations or suggestions?
