TROUBLESHOOTING
SOLID STATE HEAT PUMP CONTROL
TROUBLESHOOTING PROCEDURE
1. Turn on AC power supply to indoor and outdoor
units.
2. Turn thermostat blower switch to “Fan On” – the
indoor blower should start. (If it doesn't, troubleshoot
indoor unit and correct problem).
3. Turn thermostat blower switch to “Auto” position.
Indoor blower should stop.
4. Set system switch to heat or cool. Adjust thermostat
to call for “Heat” or “Cool” – the indoor blower,
compressor and outdoor fan should start.
NOTE: If there was no power to 24 volt transformer, the
compressor and outdoor fan motor will not start
for 5 minutes. This is because of the compressor
short cycle protection.
