The unit had tripped off and can not re-start despite contactor closing and power going to compressor.
Pulled out and open the unit and regret that one of the compressor piston has hole and stucked.
Please see attached photo.
Checked reefer container spares from previous owner, found one new unit, we intend to fit
as substitute so ECR A/C could be operational but it's operating on R134a refrigerant.
