1. Thermistors
CHECK 3
Refer to page 263.
CHECK 11
Refer to page 269.
NO
Is the
“temperature”
checked by the
Service Checker same as
the measurement of the
temperature?
NO
Replace the relevant thermistor.
Replace the outdoor unit main
PCB (A1P).
YES
YES
Service Checker
Connect the Service Checker, and then make a
comparison between “discharge pipe temperature” (or
“compressor surface temperature” and “low pressure”
checked by the Service Checker and the
measurements of discharge pipe surface temperature
(or “compressor surface temperature”).
Connect the Service Checker.
Reset the system operation,
and then restart it.
Are the characteristics
of the discharge pipe and
compressor body
thermistors normal?
(
∗
1)
CHECK 11
• All thermistors are normal, and temperature detection
with the outdoor unit main PCB is also normal.
• The discharge pipe temperature (or compressor surface
temperature) has really become high.
CHECK 3
Eliminate the causes of superheat operation.
Caution
Be sure to turn off the power switch before connecting or disconnecting
connectors, or parts may be damaged.
