Troubleshooting

 

 

  1. Is the thermostat switch set to proper positioning-cooling? Is the set-point below the room temperature?

  2. Is your furnace plugged in or is the power switch turned on? The air-conditioner needs the furnace to circulate the air.

  3. Is the air-conditioning disconnect or breaker turned on? If you know how to check the fuses, see if there are any blown. If you do not know how to check the fuses, call a technician.

  4. Is the furnace filter clean?

  5. Are the air registers open?

  6. Is the condensing unit running? (The condensing unit is the outside portion of the air-conditioner.)

  7. Is there ice on the pipes at the evaporator coil (the indoor portion of the air-conditioner)? If there is, turn off the unit and call a technician. WARNING: DO NOT SET THE THERMOSTAT BELOW 68 DEGREES. THIS CAN CAUSE A MULTITUDE OF PROBLEMS WITH YOUR AIR-CONDITIONER, INCLUDING FREEZING UP.
