If the outdoor
unit is in good
radiation?
If the air outlet and return
air inlet of the outdoor unit
is short circuited, it will
cause the radiating effect to
become poor.
If the radiator
is dirty or
blocked?
If the radiator is dirty or
blocked, it will cause the
radiating effect to become
poor.
If IPM module is
well tightened?
If IPM module is not
tightened, it will cause the
module temperature to
become too high, or even
burn the module.
If the silicate gel
on IPM module is
uniformly coated?
If the coating of silicate gel is not
uniform, it will cause poor radiation to
the module, or uneven distribution of
the temperature, or even burn the
module as the sensor cannot detect
the temperature in some area is too
high.
If the silicate gel
coated on IPM
module can meet
the requirements?
If the coating of silicate
gel is too thick, it will also
affect the radiating effect
or even burn the module.
Please check if the
sensor is failed, or
reinstall the module and
tighten it.
