5-4. Inspection of Parts (Outdoor Unit)

(1) Electronic control valve (MOV1)

MOV1: Measure the voltage between plug pin 5 and pins 1 through 4 at the CN-MOV1 connector (5P, white)
on the outdoor unit control PCB. (Because of the pulse output, a simplified measurement method is used.
Set the tester to the 12 V range; if the value displayed is approximately 4 V, then the voltage is normal.)
If the voltage is normal, measure the resistance between connector pin 5 and pins 1 through 4.
Resistance between pin 5 and pins 1 through 4 should be approximately 46
for all. (If the result is 0
or,
then replace the coil.)
