Observe the inner side of port periodically for frost and ice build-up.
Remove any frost with a soft dry cloth. If the tube should become clogged
with ice, it must be cleaned. Clear the vacuum relief tube completely free
of ice to prevent rapid ice formation.
Factors that can affect the performance of the vacuum relief port include
high ambient temperature, high humidity conditions and frequent door
openings. Perform maintenance weekly, or as needed.
Note Failure to maintain the vacuum relief port may result in excessive ice
build-up inside the tube, clogging the port, and inability to open the door.
The vacuum relief port may need to be cleaned more often with frequent
door openings and high humidity environments.
