# Measure the resistance windings of the compressor.
The resistance value will range between 0.45 to 0.88 ohms at an ambient temperature range of 20 to
25ºC.
Note:
the resistance value should be the same value
across any terminal combination.

Check the LED light code configuration.
During normal operating conditions the LED’s work in this sequence:
LED 1 (Yellow) is
ON
LED 5 (Red) is
ON
LED 6 (Green) is
OFF
During “P4” fault the LED’s work in this sequence:
LED 1 (Yellow) is
FLASHING
at 5 Hz
LED 5 (Red) is
ON
LED 6 (Green) is
FLASHING
at 5 Hz
Note:
If the LED’s are “NOT” On or Flashing, check the supply voltage to the board. If supply voltage
is okay, this would indicate the main outdoor PCB has failed.
