8 Alarm and Troubleshooting
The alarm messages detected by the dehumidifier are displayed as below:
ALARM MESSAGE CAUSE SOLUTION DEHUMIDIFIER
1# Tube temperature
sensor failure
Sensor problem Change a new one Only the faulty
system stops
Sensor wire is loose Fasten the sensor wire
1# Compressor low
pressure protection
Fan motor problem Check fan motor Only the faulty
system stops
Obstruction is return duct system Remove duct obstruction
Expansion valve problem Replace expansion valve
1# Compressor high
pressure protection
A/C condenser power off Restore power to A/C Only the faulty
system stops
A/C condenser fan gets blocked Remove blockage
Excessive refrigerant charge Remove charge to proper amount
A/C 4-way valve is not opening Repair A/C 4-way valve
1# Compressor Overload
