- if unit did not restart, call for technical support at 1-(888) 552-6467.
Turn inverter ON/OFF switch to ON position.
(Switch is located on right end of inverter module.)
Check inverter control RJ12/RJ50 cable to make sure cable it is
properly connected.
Check if yellow wire is connected. If not, connect. Refer to figure 4.
Reset system (see page 7). If result is the same, replace inverter
module.
- Verify LED Over Temp/Fault is ON on the inverter.
- Verify fan is blocked or not working.
- Call technical support at 1-(888) 552-6467.
