Outdoor AC Unit Not Turning On in NJ? What to Check First

If the indoor fan is running but the outdoor unit is quiet, the system cannot cool. In North NJ, this is often a breaker, capacitor, or contactor issue.

Safe checks you can do

• Confirm the thermostat is set to Cool and the temperature is lower than room temp
• Check the breaker for the outdoor unit
• Look for a shutoff switch near the outdoor unit and make sure it is on
• Clear debris so the unit can breathe

Common causes

• Failed capacitor
• Bad contactor
• Tripped breaker or blown fuse
• Loose electrical connection

Do not open the electrical panel on the outdoor unit. High voltage is dangerous.

• The breaker trips again after reset
• The unit hums but the fan does not spin
