Troubleshooting tips and home maintenance

Won’t cool

If the unit operates, but won’t cool, determine if the controls are properly set. Set the thermost to a cooler position in order to check control settings. Check the filter and clean it thoroughly, if needed. Check to see if the vent door is closed.

Check to see if the chassis seal gasket is properly installed (refer to page 11 for seal gasket installation).

Won’t heat (for heat/cool models only)

If the unit operates, but won’t heat, determine if the control settings are correct. Adjust the thermostat to a warmer position to determine if it operates. Also, check the filter and clean it thoroughly, if needed.

Odors in heating (for heat/cool models only)

You may notice a smoke odor the first time the heater element comes on. This is common in any type of heat system when first turned on for the winter. The odor comes from dust and other particles that accumulate during the warm months. The odor will dissipate quickly.

Won’t run

If the unit fails to operate, check to see if the power cord is fi rmly plugged in. Check for blown fuses, tripped circuit breakers or a tripped LCDI Device (Refer to LCDI reset instructions in the Power cord information section). Restore the circuit breaker or replace the blown fuse with a proper size "TIME-DELAY" fuse. The proper fuse size is shown on page 3 in these instructions. After restoring the cu- rrent supply to the unit, wait three minutes before unit will restart.
