Set 55 to 60 degrees Farhenheit
Check for voltage
Check thermistor by placing it in ice
water and measuring resistance
Check compressor windings, start relay
and overload protector.
Check for condenser fan
Clean condenser
Call service to remove refrigerant
Call service for OEM information
Check for airflow through evaporator
