Type I — Small AppliancesQuestion 109 of 240
A technician finds a household refrigerator whose sealed system was already opened and is now at 0 psig (atmospheric). During service the technician plans to recover any refrigerant present. What is the best action?
a.Recognize that most refrigerant likely already escaped, still connect recovery equipment, and recover whatever remains before repair or disposal
b.Skip recovery because the gauge reads zero
c.Add nitrogen and vent it to confirm the system is empty
d.Assume the appliance is exempt and crush it
Explanation
Even when a gauge reads zero, a technician should connect recovery equipment and remove any remaining refrigerant, since some charge may still be present in the oil or cool spots. Skipping recovery risks venting. The proper practice is to always recover before repair or disposal rather than assume the system is empty.
