too long Room or outside weather is hot. It is normal for the freezer to work harder under these conditions.
Freezer had recently been disconnected for a period of time. Freezer requires 4 hours to cool down completely.
Large amounts of warm or hot product have been stored recently. Warm product will cause the freezer to run more until the
desired temperature is reached.
Door is kept open too long or too frequently. Warm air enters the freezer every time the door is opened. Open the door less
often.
Freezer door may be slightly open.
Temperature control is set too cold. Turn the control knob to a warmer setting. Allow several hours for the temperature to

works to transfer heat from inside the freezer cabinet.
Sound and noise The fan motor in the compressor compartment is damaged or has a loose connection
Louder sound level
whenever freezer is on
Modern freezers have increased storage capacity and more even temperatures. They require a high efficiency compressor.
When the surrounding noise level is low, you might hear the compressor running while it cools the interior.
Louder sound levels when
compressor comes on 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
Metal parts undergo expansion and contraction, as in hot water pipes. This is normal. Sound will level or disappear as freezer
continues to run.
Bubbling or gurgling
sound, like water boiling
Refrigerant (used to cool freezers) is circulating throughout the system. This is normal.
Vibrating or ratting noise Freezer is not level. It rocks on the floor when it is moved slightly. Level the unit.
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 art of the freezer.
Moisture forms on inside
freezer walls Weather is hot and humid, which increases internal rate of frost build-up. This is normal.
Door is slightly open.
Door is kept open too long, or is opened too frequently.
Door is slightly open, causing the cold air from inside the freezer to meet warm moist air from outside.
