Before Calling for Service
Before calling for service, check the troubleshooting table on this page. This table lists possible problems that you can remedy without
difficulty to avoid an unnecessary service call.
OCCURRENCE POSSIBLE SOLUTIONS
Refrigerator does not run
1. Check to ensure that the refrigerator is not plugged into a circuit that has ground fault interrupt.
If you are unsure about the outlet, have it checked by a certified technician.
2. Temperature control is in the OFF position. See “Setting the Temperature Control” in the Installa-
tion section.
3. Refrigerator may not be plugged in or plug may be loose. Be sure plug is tightly pushed into elec-
trical outlet.
4. Circuit breaker has tripped. Check/reset circuit breaker.
5. Power outage. Call local electric company.
Refrigerator runs too much
or too long
1. Room or outside weather is too hot. It is normal for the refrigerator to work harder under these
conditions.
2. Refrigerator has recently been disconnected for a period of time. Refrigerator requires four (4)
hours to cool down completely.
3. Large amounts of warm commodities have been stored recently. Warm commodities will cause
the refrigerator to run more until the desired temperature is reached.
4. Door is kept open too long or too frequently. Warm air enters the refrigerator every time the
door is opened. Open the door less often.
5. Refrigerator door may be slightly open. See “Door will not close” under OCCURRENCE.
6. Temperature control is set too cold. Turn the control knob to a warmer setting. Allow several
hours for the temperature to stabilize.
7. Refrigerator gasket is dirty, worn, cracked, or poorly fitted. Clean or change gasket. Leaks in the
door seal will cause refrigerator to run longer in order to maintain desired temperature.
Temperature inside the
refrigerator is too cold
1. Temperature control is set too cold. Turn the control to a warmer setting. Allow several hours for
the temperature to stabilize.
Temperature inside the
refrigerator is too warm
1. Temperature control is set too warm. Turn the control to a colder setting. Allow several hours for
the temperature to stabilize.
2. Door is kept open too long or too frequently. Warm air enters the refrigerator every time the
door is opened. Open the door less often.
3. Refrigerator door may be slightly open. See “Door will not close” under OCCURRENCE.
4. Large amounts of warm commodities have been stored recently. Wait until the refrigerator has
had a chance to reach its selected temperature.
5. Refrigerator has recently been disconnected for a period of time. Refrigerator requires four (4)
hours to cool down completely.
Temperature of external
refrigerator surface is warm
1. The exterior refrigerator walls can be as much as 30 degrees F warmer than room temperature.
This is normal while the compressor works to transfer heat from inside the refrigerator cabinet.
Louder sound levels when-
ever refrigerator is ON
1. Modern refrigerators have increased storage capabilities 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.
