Many thanks WolfPack
for your kind post reply.
After carefullexamination of the thermal switch circuit on the inside cover of the compressor motor case, I thought I would try to test andreplace the malfunctioning parts of the circuit. I think with proper electronic tools and a tester, the thermal switch circuit would be fixed.
However, as you suggested, connecting the orange wire to the black wire with a jumperis the simplest solution for the compressor motor to work without the thermal switch interruption.
Many thanks again.
