5. Electric components malfunction inspection
No
Component name
Inspection methods
1
Compressor
Using multi-meter ohm phase, there is correct resistance value among windings (single
phase compressor refers to specification, three phase compressor resistance
approximately equal), resistance of winding should be infinite.
2
Control board
Check whether any connection part of PCB loosen or drop off, printed tinsel
andcomponents have any burn, fade, breaking off or aging phenomenon, all joints exist
short circuit phenomenon etc.
Test the circuit board system in the term of voltage, pulse on, resistance variation, by using
testing meter.
Judge the output and input is normal or not according to electric principle diagram
3
Contactor
Press the contactor by hand, the contactor reacts immediately
The contacting point of contactor has no burn and melt phenomenon
The winding has resistance value below 1000
Ω
, but cannot be nil or infinite
4
4-ways valve
winding
The winding has resistance value below 1000
Ω
, but cannot be nil or infinite
5
Capacitor
No expansion phenomenon apparently
Measure capacitor by using capacitor phase of multi-meter
6
Sensor
Using multi-meter to measure resistance, find out temperature according to resistance
table, the temperature should accord with sensor temperature.
Resistance cannot be nil or infinite
7
Motor
No burning trace apparently
Using multi-meter ohm phase, there is correct resistance value among windings (single
phase compressor refers to specification, three phase compressor resistance
approximately equal), resistance of winding should be infinite.
