TROUBLESHOOTING
OCCURRENCE POSSIBLE SOLUTIONS
Louder sound levels when
compressor comes ON
1. Freezer operates at higher pressures during the start of the ON cycle. This is normal. Sound will
level off or disappear as freezer continues to run.
Popping or cracking sound
when compressor comes
ON
1. Metal parts undergo expansion and contraction, as in hot water pipes. This is normal. Sound will
level off or disappear as freezer continues to run.
Bubbling or gurgling sound,
like water boiling
1. Refrigerant (used to cool freezer) is circulating throughout the system. This is normal.
Vibrating or rattling noise
1. Freezer is not level. It rocks on the floor when it is moved slightly. Level the unit. Refer to “Level-
ing“ in the Installation section.
2. Floor is uneven or weak. Freezer rocks on the floor when it is moved slightly. Be sure floor can
adequately support freezer. Level the freezer by putting wood or metal shims under part of the
freezer.
3. Freezer is touching the wall. Level the freezer or move slightly. Refer to “Leveling “ in the Installa-
tion section.
Moisture forms on inside
freezer walls
1. Weather is hot and humid, which increases internal rate of frost build-up. This is normal.
2. Door is slightly open. See “Door will not close” under OCCURRENCE.
3. Door is kept open too long, or is opened too frequently. Open the door less often.
Moisture forms on outside
of freezer
1. Door is slightly open, causing the cold air from inside the freezer to meet warm moist air from the
outside. See “Door will not close” under OCCURRENCE.
Odor in freezer
1. Interior needs to be cleaned. Clean interior with sponge, warm water, and baking soda.
2. Commodities with strong odors are in the freezer. Store commodities in tightly sealed containers.
Door will not close
1. Freezer is not level. It rocks on the floor when it is moved slightly. This condition can force the
cabinet out of square and misalign the door. Refer to “Leveling“ in the Installation section.
2. Floor is uneven or weak. Freezer rocks on the floor when it is moved slightly. Be sure floor can
adequately support freezer. Level the freezer by putting wood or metal shims under the freezer or
brace the floor supporting the freezer.
Light bulb is not ON
1. Light bulb is burned out. Follow directions under “Interior Light“ in the Freezer Optional Features
section.
2. No electric current is reaching the freezer. See “Freezer does not run” under OCCURRENCE.
