TROUBLESHOOTING
SOLUTIONS
· When outdoor temperature is approximately 55°F or below, frost may form on
the indoor coil when unit is in Cooling Mode. Switch unit to FAN operation until ice
or frost melts.
· Remove and clean filters
· Random Compressor restart - Whenever the unit is plugged in, or power has been
restarted, a random restart will occur. After a power outage, the compressor will
restart after approximately 3 minutes.
· Compressor Protection - To prevent short cycling of the compressor, there is a
random startup delay of 3 minutes and a minimum compressor run time of 3
minutes.
· Clean the evaporator once every three months by professional people.
NOTES:
1. If circuit breaker is tripped or fuse is blown more than once, contact a qualified electrician,
2. If unit is installed where condensation drainage could drip in an undesirable location, an accessory drain kit should be
installed and connected to drain system.
· Dirty filters
· Low outdoor temperature
ICE OR FROST FORMS ON INDOOR COIL
· Power may have cycled, so compressor is in a restart
protection.
