Fist
disable humidity sensor
disable VPS sensor
superheat low and sub cooling high
no liquid in the receiver
perhaps incondensable gases in the system
Make a vacuum 500microns and charge Freon
Check transducer superheat
Check resistence ETS1 sensor
It is very simple check TXV economizer and reading on CD12 (EXPANSION VALVE STUCKED IN CLOSE POSITION) liquid coming from economizer system making ice on compressor
low gas try to charge freon
Humidity sensor defective
No
