Simple solutions to attempt before calling your Carrier dealer
If you experience any trouble with your Carrier Products or system, you may always call your Carrier dealer for help and service. But here are a few simple solutions you can attempt before calling your expert Carrier dealer to your home for a service visit.

Air Conditioning Equipment Checklist

1- Check to make sure that your thermostat is set in the "cool"
position. And the ON-OFF switch is on the “ON” position.

2- Check the circuit breakers in the circuit breaker box
(or electrical panel). Are they in the "On" position?

3- Check the outdoor unit "disconnect switch" to make sure it is
in the "ON" position. The disconnect switch is located near
the outdoor unit. (Typically a small electrical box mounted to
the wall within reach of the unit).

4- Ensure that the blower motor in your indoor unit is running.

5- Make sure your filters are clean.
