Why the other answers are wrong
- Checking the nameplate — The nameplate identifies the refrigerant but cannot verify a repair.
- Measuring compressor amperage — Amperage does not check whether a leak was repaired.
- Weighing the recovery cylinder after the repair — Cylinder weight does not test the repaired joint.
