Central Air Conditioning Troubleshooting
1. First make sure that the thermostat is set lower than the actual room temperature. The selector switch must be on "cool." If the thermostat is programmable, be certain it has fresh batteries. 2. Check for power by moving the fan switch from "auto" to "on." If the blower runs, there is power. If nothing happens, a control is burned out or power is disconnected. If the system uses a furnace for heat, check that the emergency switch is on. If you are familiar with the fuse or circuit breaker panel, check for blown fuses or tripped breakers. Correct the problem one time only. If it repeats, call for service. Get up to 4 Free Quotes!
