Haier HSU-09H03/R(DB) [86/131] Exhaust temperature sensor is broken and needs be replaced
Yes
Electrify the machine again and turn it on
with the remote controller, then measure the
temperature at the exhaust temperature
sensor of the compressor on the outdoor unit
and check whether the temperature exceeds
117 shortly after the machine starts ć up
Measure the temperature at the
exhaust temperature sensor of the
compressor on the outdoor unit and
Malfunctions occur after running for
some time even though the measured
tem
perature is below 110ć.
Pull out the exhaust sensor and measure
its resistance at standard temperatures.
Check whether the results deviate much
from those in the resistance-temperature
table
1) The cryogen may have
been leaked during
installation, or there may
be leakage in the piping
system.
2) There may be other
causes to make the
exhaust temperature too
high.
