refrigerant during normal operation. A flooded evaporator
should maintain constant pressure and temperature across
the entire coil, from inlet to outlet. The mixture of gas and
liquid refrigerant enter the accumulator after leaving the
evaporator coil. The accumulator prevents any liquid
refrigerant from reaching the compressor. The compressor
evacuates the cool refrigerant gas from the accumulator
and compresses it to a high pressure and temperature gas
to repeat the process.
8.2 Troubleshooting
FOR THE HOMEOWNER:
n
If the unit does not work properly, please check the
following:
— Is the unit unplugged?
— Is power to outlet on? (check switch, if applicable)
— Is circuit breaker tripped?
— Is humidity control set? (turn to “ON”)
— Is air flow restricted? (check air filters and grill)
If none of the above, call dealer or 1-800-533-7533.
FOR THE HVAC PROFESSIONAL:
n
No dehumidification. Neither blower, nor compressor run
with fan switch AUTO.
1. Unit unplugged or no power to outlet, circuit breaker
tripped.
2. Humidity control set to “Humid” setting.
3. Loose connection in internal wiring.
4. Humidity control is defective.
n
No dehumidification. Compressor does not run but
blower runs with fan switch AUTO and humidity control
turned to ON.
1. Defrost thermostat open, ambient temperature too low.
2. Loose connection in compressor circuit.
3. Defective compressor overload.
4. Defective compressor or compressor run capacitor.
n
Blower runs with fan switch AUTO but compressor
cycles on & off.
1. Low ambient temperature and/or humidity causing unit
to cycle through defrost mode.
2. Defrost thermostat defective.
3. Defective compressor overload.
4. Defective compressor.
n
Blower does not run with fan switch in either position.
Compressor runs briefly but cycles on and off.
1. Loose connection in blower circuit.
2. Obstruction prevents impeller rotation.
3. Defective blower.
4. Defective blower switch.
n
Evaporator coil frosted continuously, low dehumidifying
capacity.
1. Dirty air filter or air flow restricted.
2. Defrost thermostat loose or defective.
3. Low refrigerant charge.
If none of the above has fixed the issue, call technical
support at 1-800-533-7533.
