Troubleshooting tips and home maintenance

Won’t cool

If the unit operates, but won’t cool, determine if the controls are properly set. Wait three minutes before setting the thermostat 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 14 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.

Frosting of the indoor coil

Certain operating conditions may produce indoor coil frost. During the cooling operation, a dirty filter or restricted air distribution in combination with cool, damp weather could cause such an occurrence. Should the indoor coil frost over while cooling, set the control to FAN and keep it running until the frost on the coil is gone. Setting the thermostat to a slightly warmer position will probably keep the coil from frosting over again.

Cleaning the decorative front

The decorative front of your Friedrich room air conditioner, as well as the complete cabinet, may be cleaned with warm water and mild detergent. Under adverse operating conditions, the indoor and outdoor coils and base pan may require periodic cleaning to maintain efficient operation. Your Friedrich dealer should be called when this service is required.

Won’t run

If the unit fails to operate, check to see if the power cord is firmly 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 pages 4 and 7 in these instructions. After restoring the current supply to the unit, wait three minutes before restarting.

Things to know about a WallMaster heat pump

During the heat pump operation, you may notice some functions that did not occur when the unit was used for cooling:

1.It is common for ice to form on the outdoor coil of your WallMaster Heat Pump. The ice forms due to moisture in the outdoor air passing over cold (below freezing) coil surfaces.

2.When the outdoor coil forms ice, your heat pump will automatically initiate a defrost. The compressor will stop and the fan will continue to run. The electric heat will be turned on to continue warming the room while the outdoor air defrosts the outdoor coil. After the defrost is completed, the unit will automatically return to the heat pump mode.

3.It is normal for vapor (steam) to rise from the outdoor coil during the defrost. This is similar to expelling warm breath on a cold morning.

4.If the outdoor temperature drops below 43°F during heat pump operation, your WallMaster Heat Pump will automatically switch to electric resistance heat and will continue to operate in this mode as long as the outdoor temperature remains at 43°F or below.
