Troubleshooting  

Problem: Ice maker is not making any ice.

Cause:

1. Ice maker wire signal arm is in the “up” or OFF position.
2. Household water line valve is not open.
3. Freezer is not cold enough.
4. Saddle valve on cold water pipe is clogged or restricted by foreign material.

Correction:

1. Move wire signal arm to the “down” or ON position (side mounted).
2. Turn on household water line valve.
3. See PROBLEM column TEMPERATURES ARE TOO WARM.
4. Turn off household water line valve. Remove valve. Ensure that valve is not a self-piercing saddle valve. Clean valve. Replace valve if necessary.

Problem: Ice maker is not making enough ice.

Cause:

1. Ice maker is producing less ice than you expect.
2. Freezer is not cold enough.
3. Household water line valve is not completely open.

Correction:

1. The ice maker will produce 2 to 3 pounds of ice every 24 hours depending on usage conditions. Ice is produced at a rate of 8 cubes every 75 to 160 minutes.
2. See PROBLEM column TEMPERATURES ARE TOO WARM.
3. Turn on household water line valve.

Problem: Ice maker will not stop making ice.

Cause: Ice maker wire signal arm is being held down by some item in the freezer

Correction: Move item and release wire signal arm. Remove any ice cubes that are frozen together over the wire signal arm

Problem: Ice cubes are freezing together.

Cause:

1. Ice cubes are not being used frequently enough.
2. Freezer control is set too warm.
3. Very little food in freezer.

Correction:

1. Remove ice container and discard ice from container. Ice maker will produce fresh supply.
2. Set freezer control to colder setting. Allow 24 hours for temperature to stabilize.
3. Add more food to freezer.

Problem: Ice has bad odor and taste.

Cause:

1. Ice has picked up odor or flavor from strong food stored in refrigerator or freezer.
2. Water running to ice maker has poor taste or odor.
3. Ice not used frequently enough.

Correction:

1. Cover foods tightly. Discard stale ice. Ice maker will produce fresh supply. Replace air filter (available in select models).
2. Add filter to water supply line. Consult a water purifying company.
3. Discard stale ice.

Problem: Light bulb is not on.

Cause:

1. Light bulb is burned out.
2. No electric current is reaching refrigerator.

Correction:

1. See Replacing Light Bulbs in NORMAL OPERATING SOUNDS section.
2. See PROBLEM column RUNNING OF REFRIGERATOR.

Problem: Interior is dirty.

Cause:

1. Interior needs to be cleaned.
2. Food with strong odors is in refrigerator

Correction:

1. See table of Care and Cleaning Tips in CARE & CLEANING section.
2. Cover food tightly.

Problem: Door(s) will not close.

Cause:

1. Door was closed too hard, causing other door to open slightly.
2. Refrigerator is not level. It rocks on the floor when moved slightly.

Correction:

1. Close both doors gently.
2. Ensure floor is level and solid, and can adequately support the refrigerator. Contact a carpenter to correct a sagging or sloping floor.

Problem: Drawers are difficult to move

Cause:

1. Food is touching shelf on top of drawer.
2. Track that drawers slide on is dirty.

Correction:

1. Remove top layer of items in drawer.
2. Ensure drawer is properly installed on track.
3. Clean drawer, rollers, and track. See table of Care and Cleaning Tips in CARE & CLEANING section.

Problem: Compressor does not run

Cause:

1. Refrigerator is in defrost cycle.
2. Plug at electrical outlet is disconnected.
3. House fuse blown or tripped circuit breaker.
4. Power outage.

Correction:

1. This is normal for a fully automatic defrost refrigerator. The defrost cycle occurs periodically, lasting about 30 minutes.
2. Ensure plug is tightly pushed into outlet.
3. Check/replace fuse with a 15 amp time-delay fuse. Reset circuit breaker.
4. Check house lights. Call local electric company.

Problem: Refrigerator runs too much or too long.

Cause:

1. Room or outside weather is hot.
2. Refrigerator has recently been disconnected for a period of time.
3. Automatic ice maker is operating.
4. Doors are opened too frequently or too long.
5. Fresh Food/freezer door may be slightly open.
6. Fresh Food/freezer gasket is dirty, worn, cracked, or poorly fitted.

Correction:

1. It is normal for the refrigerator to work longer under these conditions.
2. It takes 8-12 hours for the refrigerator to cool down completely.
3. Ice maker operation causes refrigerator to run slightly more.
4. Warm air entering the refrigerator causes it to run more. Open doors less often.
5. Ensure refrigerator is level. Keep food and containers from blocking door. See PROBLEM column OPENING/ CLOSING OF DOORS/DRAWERS.
6. Clean or change gasket. Leaks in door seal will cause refrigerator to run longer in order to maintain desired temperatures.

Problem: Compressor goes off and on frequently.

Cause: Thermostat keeps the refrigerator at a constant temperature.

Correction: This is normal. Refrigerator goes on and off to keep temperature constant.

Problem: Freezer temperature too cold. Fresh Food temperature is satisfactory

Cause: Freezer control is set too cold.

Correction: Set freezer control to a warmer setting. Allow 24 hours for temperature to stabilize

Problem: Fresh Food temperature too cold. Freezer temperature is satisfactory.

Cause: Fresh Food control is set too cold.

Correction: Set fresh food control to a warmer setting. Allow 24 hours for temperature to stabilize.

Problem: Food stored in drawers freezes.

Cause: Fresh Food control is set too cold.

Correction: See solution above.

Problem: Freezer/Fresh Food temperature is too warm.

Cause:

1. Doors are opened too frequently or too long.
2. Door is slightly open.

Correction:

1. Warm air enters the refrigerator whenever the door is opened. Open the door less often.
2. See PROBLEM column OPENING/ CLOSING OF DOORS/DRAWERS.

Problem: Freezer temperature is too warm. Fresh Food temperature is satisfactory.

Cause: Freezer control is set too warm.

Correction: Set freezer control to a colder setting. Allow 24 hours for temperature to stabilize.

Problem: Fresh Food temperature is too warm. Freezer temperature is satisfactory.

Cause: Fresh Food control is set too warm.

Correction: Set Fresh Food control to a colder setting. Allow 24 hours for temperature to stabilize.

Problem: Moisture collects on inside of refrigerator walls.

Cause:

1. Weather is hot and humid.
2. Door is slightly open.
3. Door is opened too often or too long.
4. Open containers.

Correction:

1. The rate of frost buildup and internal sweating increases.
2. See PROBLEM column OPENING/ CLOSING OF DOORS/DRAWERS.
3. Open door less often.
4. Keep containers covered.

Problem: Water collects on bottom side of drawer cover.

Cause: Vegetables contain and give off moisture

Correction:

1. It is not unusual to have moisture on the bottom side of the cover.
2. Move humidity control (some mod- els) to lower setting.

Problem: Water collects in bottom of drawer.

Cause: Washed vegetables and fruit drain while in the drawer.

Correction: Dry items before putting them in the drawer. Water collecting in bottom of drawer is normal.

Problem: Moisture collects on outside of refrigerator or between doors

Cause:

1. Weather is humid.
2. Door is slightly open, causing cold air from inside refrigerator to meet warm air from outside.

Correction:

1. This is normal in humid weather. When humidity is lower, the moisture should disappear.
2. See PROBLEM column OPENING/ CLOSING OF DOORS/DRAWERS.
