A verification test performed after a leak repair shows that the repaired joint is still losing refrigerant. What is the correct response to that result?
Correct Answer
B) Treat the repair as incomplete, repair the leak again, and run the verification test over from the start
A verification test exists to answer one question: did the repair hold. A failed test means the answer is no, so the job is not finished. The technician goes back to the joint, makes a proper repair, and tests again, because a leak that is documented but not fixed is still a leak releasing refrigerant. Charging a system that is known to be leaking and planning to look at it next season is a deliberate release. Sealant is not a repair and can cause its own trouble in the metering device and the recovery equipment.
Why This Is the Correct Answer
The repair and the verification form a loop that only closes when the test passes. Failing the test returns the technician to the repair step. Anything else leaves refrigerant escaping from a leak the technician already knows about, which is the situation the rules are written to prevent.
Why the Other Options Are Wrong
Option A: Charge the system back up and put a follow-up leak test on the schedule for the beginning of next cooling season
Charging a system that has just failed its verification test puts refrigerant into a known leak, and waiting a season lets it all go back out. A failed test means the repair is not finished.
Option C: Record the failed result on the service ticket and treat the repair attempt as closed out
Writing down a failure is not the same as correcting it. The record shows the work is unfinished, which is evidence against closing the ticket rather than permission to close it.
Option D: Add a sealant product to the charge so the remaining leak seals itself once the system runs
Sealants are not an accepted repair. They plug metering devices and driers, contaminate recovery equipment, and make the eventual real repair harder than it would have been.
Memory Technique
Test, fail, fix, test again. The loop does not open until the joint holds.
Reference Hint
40 CFR Part 82, Subpart F requires an initial verification test and a follow-up verification test, and a repair that fails verification has not been completed.
