* Use the Multimeter to check the
continuity
* Take out the capillary from Freezer
* Use the Multimeter to check the
continuity
* All components & wires are properly "Earthed"
* Green LED is "ON" when Compressor is "ON" & it's "OFF" when
Compressor is "OFF"
* Red LED is "ON" when Power is "ON" & it's "OFF" when
Power is "OFF"
* Both LEDs are straight & not bend
* Any component on PCB is burnt
* Black wire is connected to Common, Red wire is connected to Power &
Blue wire is connected to Compressor, as written on PCB
