Testing the Voltage
Use a multimeter and switch to DC voltage to test the 2 port
and 3 port of the outdoor unit. The red pin of multimeter
connects with 2 port while the black pin is for the 3 port.
•
When the unit is running normal, the voltage will
move alternately between -25V to 25V.
•
If the outdoor unit is faulty, the voltage will move
alternately with positive value.
•
If the indoor unit is faulty, the voltage will be a
specific value.
Testing the Reactor
Use a multimeter to test the resistance of the reactor.
NOTE: The reactors are not attached to the capacitors.
•
The
normal value should be around zero ohms (0 Ω).
If otherwise, the reactor is faulty and must be
replaced.
