Error code Error description Possible cause/remedy
32# Liquid line probe defective
Liquid line excessive temperature
- If the error appears <1 minute after turning
on the unit, the THOP probe (PCB 3) is
defective.
Replace it.
- If the error only appears after operating for
some time, a lack of refrigerant can be the
cause or the fan motor of the outdoor unit is
not working properly
. If the temperature on
the THOP probe rises above 58 °C, the unit
switches off and error code "32" appears on
the display.
33# Compressor probe defective - THCT temperature sensor (PCB 3) defec-
tive. Replace the probe.
- Is there an excessive temperature on the
compressor or is the outside temperature
too high? Is the outdoor unit fan motor
working properly?
35# Speed control of the compressor faulty - Compressor possibly defective
- Replace the IPM circuit board (PCB 4).
36# Heat gas temperature on the compressor
too high
Compressor defective?
- Is there an excessive temperature on the
compressor or is the outside temperature
too high? Is the outdoor unit fan motor
working properly?
37# Liquid line temperature too high - see error code 32
38# AC voltage on motherboard (PCB 3) too low.
T
ransformer on circuit board not OK.
- Replace motherboard (PCB 3)
39# AC voltage on motherboard (PCB 3) too
high. T
ransformer on circuit board not OK.
- Replace motherboard (PCB 3)
40# Motherboard current consumption faulty - Replace motherboard (PCB 3)
41# IPM circuit board communication error Check the 5-wire connecting line and con-
tacts CN1 (PCB 4) - CN1
11 (PCB 3) and
CN2 (PCB 4) - CN110 (PCB 3).
42# IPM circuit board defective - Replace IPM circuit board
43# Overvoltage (DC) on IPM circuit board - Replace IPM circuit board
44# IPM module current consumption faulty - Replace IPM circuit board
45# Power supply too high or low - Check the electrical power supply
46# General IPM error - Replace IPM circuit board
47# PFC module on IPM circuit board defective - Replace IPM circuit board
