Compressor will not run
while fan motor runs.
Check voltage. Call Supply Authority if not within limits.
Check the wire connections, if loose, repair or replace the terminal.
If wires are off, refer to wiring diagram for identification, and
replace. Check wire locations. If not per wiring diagram, correct.
Check voltage of main PCB. Replace the main PCB if open.
Capacitor (Discharge
capacitor before testing)
Check the capacitor. Replace if not within +/-10% of
manufacturers rating. Replace if shorted, open, or damaged.
Check the temperature setting if not at the coolest (in cooling
mode) or the warmest (in heating mode). Set it if not.
Check the compressor for open circuit or ground. If open or
grounded, replace the compressor.
Remove the cabinet and carefully rearrange tubing not to contact
cabinet, compressor, shroud and barrier.
Check and pour if the water tank is full.
Water depth sensor if
failure
Check and replace if failure.
Water depth is over load
in chassis
Check and drainage the water in the chassis by open the drainage
hose on the chassis.
Water depth sensing
structure
Check and replace or realign if the structure is failure.
Dehumidifier does not
dry the air as it should
Clean or replace if restricted.
The humidity control may not be set low enough
Determine if the unit is properly sized for the area
Clean or replace if restricted.
Check the fan capacitor and replace if not within +/-10% of
manufactures rating.
Clean or remove if any barrier is found to block the wind flow of the
unit.
Check the tubes for reasons of leakage. Recycle the refrigerant,
correct the leakage points and recharge.
Regulate the flow if capillary tube and make the evaporating
temperature appropriate if the evaporator is frosted. Replace if
blocked. Repair joint if leaking.
The inlet and outlet valve of the compressor is damaged, making
the low pressure connected with the high pressure. The
refrigerating system can not produce high pressure and low
pressure. Replace the compressor after checking for the reason.
Check and adjust the mode setting.
Check and replace if the compressor, the over-load protector or
wiring is broken.
This is normal, the dehumidifier has Auto-defrost feature.
