8-3. Checking flow chart
8-3-1. Compressor doesn’t start
Compressor no working
Check if the home power
connected well?
Connect the power
NO
YES
Check if input and output
voltage of control board is
normal?
No
Test the input and output voltage using a multimeter .if input
voltage is normal but there is no output voltage, it means the
control board is failure.
Check if the starter is normal?
Test resistance of PTC starter, if it is ZERO or INFINITE, means the starter is out of work.
For PTC starter, when shake it, it should not have noise, if it has, means the starter Magnetic
Disk burned.
YES
Check if the overload
protector is normal?
1. Measure whether two ends of overload protector is through using

2. Measure starting current and running current of compressor using
clamp-type tester. If overload protector act when current is normal,
means protector failure and should be replaced.
YES
Check if the run capacitor is
normal?
Before measurement, remove the capacitor from circuit firstly, and
then connect two terminals for discharge.
1. If the finger of multimeter swings to 0 quickly and then swings
back slowly when measuring two poles of capacitor, it means the run
capacitor is normal.
2. If the finger of multimeter does not swing, it means the run
capacitor is open circuit. If the finger of mulimeter swings to 0 and
stops means it is short circuit, if it stops on any other position, it
means the capacitor leaka
