The compressor in a small appliance will not turn at all, and the technician pulls the unit down to four inches of mercury vacuum using a 2018 recovery machine. How does that result stand against the requirement?
Correct Answer
B) It satisfies the requirement, because the vacuum route stands on its own whatever the compressor is doing
The vacuum alternative is a separate way of meeting the small appliance requirement, not a bonus attached to one of the percentage branches. It is stated as a pressure to be reached at the appliance, and nothing in it turns on whether the appliance compressor operates. A seized compressor makes the job slower, because the technician loses the pumping help the appliance would otherwise give, and it means access has to be gained where the refrigerant actually is. It does not change what counts as done. Reaching and holding four inches of mercury vacuum is enough.
Why This Is the Correct Answer
Reaching four inches of mercury vacuum at the appliance is a complete way of satisfying the small appliance recovery requirement on its own. The compressor condition test belongs to the percentage branches, where it decides between ninety and eighty percent. Once a technician takes the vacuum route, that test no longer has anything to act on, so a seized compressor changes the difficulty of the job but not the standard.
Why the Other Options Are Wrong
Option A: It fails, because a seized compressor forces the eighty percent route to be used instead
A seized compressor does point a technician toward eighty percent if the percentage route is chosen, but it does not close off the vacuum route, which remains available on any small appliance.
Option C: It fails, because the vacuum route opens up only when the appliance compressor is running
This reverses the rule. The vacuum reading is a property of the appliance under the machine's pull, and a dead compressor is precisely the situation in which technicians reach for it most often.
Option D: It counts, but only once the same unit is also weighed against its listed factory charge
The two routes are alternatives, not a pair that must both be shown. Weighing the recovery on top of a satisfied vacuum reading is extra work that proves nothing further.
Memory Technique
Percentages ask how the compressor is doing. The vacuum does not care.
Reference Hint
Small appliance recovery is met by the percentage route or by four inches of mercury vacuum. The vacuum route carries no compressor condition.
