Linde pack

[graydog]

I'm working on a linde pack with a compressor that's been alarming out for 59weeks! I just can't clear the alarm, I push the contactor in and everything works and the crankcase heater cuts out which leads me to believe it's a control fault? Iv changed the klixon but still alarming iv tried following the wires but with no diagram this is difficult, can anyone help?

the wiring on these packs are a nightmare, if its the type with switches on the panel door that turn compressors between off/on and auto, try there the switches alaways burn out, also common fault is bad neutrals, good luck!
