Check Point 1
Disconnect the connection wires between the Transistor
PCB - Capacitor PCB and Transistor PCB - Inverter
Compressor.
Set the tester to the "Resistance" mode, and measure
the resistance between the following terminals.
TM301 (P) - TM305(U) / TM304(V) / TM303(W)
TM302 (N) - TM305(U) / TM304(V) / TM303(W)
