J2-MI lid release
I’ve got a J2-MI that won’t release the lid, except manually through the emergency access hole. The solenoid that releases the latch handle doesn’t operate, though it does move freely by hand. I also noticed the motor won’t start. Everything functions on the operator panel, but when I press start nothing happens with the drive. The timer begins counting down, but then gives a “Speed” error after about 15 seconds. The drive belt is ok, the safety connector is joined, and the motor turns freely by hand. The lid switch is secure and ohms out good, and I can hear it click over when the lid eyebolt contacts it. The compressor runs with the lid open. Does the high voltage board discussion on the recent J2-21 thread apply here as well?
