The question
Under 40 CFR 82.152, which of these is not considered "opening an appliance"?
- Removing a compressor for replacement
- Connecting hoses and gauges to measure pressureCorrect answer
- Cutting a refrigerant line to replace a drier
- Unbrazing a condenser coil
Why “Connecting hoses and gauges to measure pressure” is correct
The definition of opening an appliance covers service that would release refrigerant to the atmosphere. Connecting and disconnecting hoses and gauges to measure pressures, add refrigerant or recover refrigerant is specifically not "opening," though it still requires certification.

- Unbrazing a condenser coil — Unbrazing a coil opens the refrigerant circuit.
