11. Troubleshooting
Problem Possible Cause Solution
Compressor will not run
while fan motor runs
(continued) Room Temp Sensor Check the temperature setting if not at the coolest (in cooling
mode) or warmest (in heating mode). Set it if not.
Compressor Check the compressor for open circuit or ground. If open or
grounded, replace the compressor.
Copper tubing Remove the cabinet and carefully rearrange tubing not to contact
cabinet, compressor, shroud and barrier.
Water tank full Check and pour if the water tank is full.
Water level sensor Check operation. Drain water if full. Replace if tank is empty and
code is set.
Water depth is overloaded in
chassis Check and drain the water in the chassis by opening the drainage
hose on the chassis.
Water depth sensing structure Check and replace, or realign if the structure failed.
Air filter
Clean or replace if restricted.
Air discharge pipe Realign and assemble if the installation of the air discharging pipe
failed. Replace if damaged.
Unit undersized Determine if the unit is properly sized for the area to be cooled or
heated.
Condenser and Evaporator Clean or replace if restricted.
Circulation in condensing
water Check whether water damaged the motor or if the water hose is
blocked.
Fan motor Check the fan capacitor and replace if not /-10% of
manufacturer’s rating.
Air flow Clean or remove if any barrier is found to block the inlet/outlet
airflow of the unit.
Less refrigerant Check the tubes for leakage points. Recycle the refrigerant,
correct the leakage points and recharge.
Capillary tube Regulate the capillary tube flow and make the evaporating
temperature appropriate if the evaporator is frosted over. Replace
if blocked. Repair joint if leaking.
Compressor The inlet and outlet valve of the compressor is damaged,
making the low pressure connected with the high pressure.
The refrigerating system cannot produce high pressure and low
pressure. Replace the compressor after checking for this.
No power Check the voltage. Call an electrician if not within the limit.
Wiring Check the terminals. Repair and correct if loose.
Temperature setting Check and adjust the temperature setting.
Compressor Check and replace if the compressor, the overload protector or
wiring is broken.
Overheat fuse failure Check and replace if the fuse is damaged.
Main PCB Check the voltage of the main PCB. Replace the main PCB when
the unit fails in heating mode.
Power supply The input power supply voltage is too low. Call an electrician if not
within limits.
Main PCB Check and replace the main PCB if the compressor relay on the
PCB is shorted or damaged.
Room temperature When the room temperature is too high, the compressor will
protect.
