Question about Carrier Heating & Cooling
If you have access to a multi meter tester you need to check the voltage at the top of the contactor you hear and at the bottom with the contactor closed should have 240 volts ac (+ or-) top and bottom (Line and Load)
if you have voltage at the top and not at the bottom replace contactor or check for debris in the contacts and remove --also check for blackened or burnt contacts also(shut off electric first)
check your circuit breaker for your outdoor unit from the house panel for on position and it may be labeled a/c unit or outdoor unit
check the box near your outdoor unit for a breaker off or tripped or if you have fuses check to see if they are good with a contiuity tester, Again with the power to be off in doing so.
if fuses are good you will have continuity across them( a reading) if not no continuity(no reading fuse bad)
