This Grade 1 assessment template evaluates essential refrigeration engineering competencies. It covers testing compressor windings and pump-down, checking pressure differential across liquid drier cores and replacing them, setting compressor pressure switches using nitrogen, verifying oil differential operation and reporting oil pressure, diagnosing floodback causes, adding oil and explaining the oil system including reservoir differential valves and oil separators, performing electronic leak testing, measuring voltage and amps on live compressors and fan motors, and explaining off-cycle, electric, and hot gas defrost methods. Use it to standardize technician evaluations and document competency sign-offs.
