CHECK A FOLLOWING STEPS
Both power module
and PCB (TAG main)
are normal
Measure both voltages as follows
without taking off the connectors.
between 7 in the 15 and 1
in the 16 approx. DC 12V
± 2V
between 6 in the 16 and 7
approx. DC 22V

3V
METHOD OF CHECK
DC current detection and in case of irregular work of compressor
check the damage of piping, excess gas
check the resistance of power module
