Trouble Shooting

Before you call for service, read the following information. Failure to do so may result in a service charge, even if the equipment is under warranty.

1. Check the indoor and outdoor disconnect switches. Verify that circuit breakers are
   ON or that fuses have not been blown.
2. Check for sufficient airflow. Check the air filter(s) for any accumulations of dirt. Check for blocked return-air or supply-air registers. Be sure registers are open and unobstructed.
3. Check the settings on your indoor thermostat. If you desire cooling, make sure that the temperature control selector is set below room temperature and the SYSTEM or MODE control is set to COOL or AUTO. If you require warmth, make sure that the temperature control selector is set above room temperature and the SYSTEM or MODE control is set to HEAT or AUTO.
4. Do not operate your unit in cooling mode when outdoor temperatures are below 55 degrees F, unless your unit was modified for low-ambient operation.
5. Check gas/oil supply.
   

FOR HEAT PUMPS ONLY:

7. Ice or frost will tend to form on the outdoor coil during the winter heating operation. Your heat pump is designed to automatically melt the ice. When in this defrost cycle, it is normal for steam or fog to rise from the outdoor unit. Do not be alarmed!
8. If the Condenser unit fails to operate during the winter season, switch the T-Stat to emergency heat mode. This will provide back-up heat. Call for service during normal working hours if possible. “AFTER HOUR SERVICE” rates ARE higher.
