Turn on the unit with the remote
control. Measure the temperature at
the exhaust temperature sensor of the
compressor on the outdoor unit.
Does the temperature exceed 230°F?
The refrigerant may have leaked during
installation or there may be leakage in
the piping system. There may be other
causes for the overly high exhaust
temperature.
Malfunctions occur after running
for some time even though the
temperature is running below 230°F.
Pull out the exhaust sensor and
measure its resistance at standard
temperatures according to the
resistance temperature table
The sensor is damaged and must be
replaced.
Is there a deviation in the results?
