• Be sure the thermostat is set to “cool” and that the set temperature is well below the your existing room temperature.
• Make sure there aren't any blown fuses or tripped breakers. A central air conditioner should be on a dedicated 240-volt circuit. If this is the problem, simply reset the breaker or replace the fuse. If it continues to be a problem, you should consider modifying your electrical.
• Make sure the power switch is turned on and that the outdoor condenser’s power switch (mounted on the outdoor unit) hasn’t been turned off. Also be sure the 240-volt disconnect next to the compressor (usually in a metal box mounted on the house wall) hasn’t been shut off.
• Turn off the power to the air conditioner and check the thermostat. Remove the thermostat’s cover and unscrew the wire from the Y terminal. Turn the power back on. Holding the wire by its insulation only, touch the bare end to the R terminal and hold it there for about two minutes. If the compressor kicks on, the thermostat is faulty; replace it or call Blue Dot Services. If the compressor doesn’t go on when you hold the two wires together, turn the power back off and call (410) 879-9696.
