Safety information
- Plug the unit into a dedicated, grounded 115 V / 60 Hz outlet. Do not use an extension cord, adapter plug or a GFCI-protected kitchen circuit unless local code requires it.
- Use two or more people to move and install the appliance; a refrigerator is top-heavy when the doors are open.
- Never let children climb, sit or stand on shelves, drawers or doors.
- Before disposing of an old refrigerator, remove the doors and leave the shelves in place so children cannot become trapped inside.
- Unplug the unit (or switch off the breaker) before replacing a light bulb, cleaning the condenser or performing any repair.
Installation and first-time setup
Measure the installation space and every doorway on the delivery path before the unit arrives. This model is 23.8 in. wide and 34.1 in. tall; allow about 1 in. of extra width and height in the opening so air can circulate and the doors can swing past adjacent cabinets.
- Choose the location
Pick a level floor away from ovens, heating vents and direct sunlight. Room temperature between 55 °F and 110 °F (13–43 °C) keeps the compressor working in its design range — avoid unheated garages in winter unless the manufacturer rates the model for garage use.
- Unpack and inspect
Remove all tape, foam and shipping blocks, including any compressor shipping bolts noted on a tag at the rear. Check that the cabinet and doors are undamaged.
- Let it stand
If the refrigerator was transported on its side, stand it upright for at least four hours (overnight is better) before plugging it in so compressor oil can drain back.
- Level the cabinet
Adjust the front leveling legs or rollers so the cabinet is level side to side and tilted very slightly backward. This helps the doors close by themselves and seal properly.
- Power on and cool down
Plug in the unit and leave the controls at the factory setting. Allow 4–6 hours for the cabinet to reach temperature before loading fresh food.
Using your refrigerator
Recommended temperature settings
| Compartment | Target | Why |
|---|---|---|
| Fresh-food section | 37 °F (3 °C) | Keeps food below the 40 °F (4 °C) food-safety limit without freezing produce. |
| Beverage storage | 38–45 °F (3–7 °C) | Cold enough for drinks while avoiding frozen cans. |
Change the setting one step at a time and wait 24 hours before adjusting again. An inexpensive appliance thermometer placed in a glass of water on the middle shelf gives the most accurate reading.
Organizing food for even cooling
- Store milk, eggs and raw meat on interior shelves — the door bins are the warmest part of the cabinet.
- Keep raw meat, poultry and fish on the lowest shelf in a sealed container so juices cannot drip onto ready-to-eat food.
- Use the high-humidity crisper for leafy greens and the low-humidity drawer for fruit that releases ethylene, such as apples and pears.
- Do not block the air vents at the back of the compartment; leave a small gap between packages so cold air can circulate.
- Let hot food cool briefly, but refrigerate leftovers within two hours of cooking.
Care and maintenance
| When | What to do |
|---|---|
| Every week | Discard expired food and wipe up spills while they are fresh. |
| Every month | Wash shelves and bins with warm water and mild dish soap; dry thoroughly. Avoid abrasive cleaners on plastic liners. |
| Every 3 months | Check the door gaskets: close the door on a strip of paper — if it slides out easily, clean the gasket or have it replaced. |
| Every 6–12 months | Unplug the unit and vacuum the condenser coils (behind the toe-grille or at the rear) to keep the compressor running efficiently. |
| Before a long absence | Remove food, unplug, clean and dry the interior, and prop the doors open to prevent odor and mold. |
Troubleshooting
Most refrigerator problems can be solved without a service call. Work through the checks below before contacting an authorized technician.
| Problem | Possible cause | What to try |
|---|---|---|
| Fresh-food section is too warm | Control set too warm; vents blocked by food; door not sealing; dirty condenser coils. | Set to 37 °F and wait 24 h; rearrange items away from vents; clean gaskets and check leveling; vacuum the coils. |
| Runs all the time | New unit still pulling down; hot room; frequent door openings; dirty coils. | Allow 24 h after installation; improve ventilation around the cabinet; clean the coils. Modern high-efficiency compressors run longer at lower speed by design. |
| Frost or ice inside the freezer | Door left ajar; worn gasket; humid air entering. | Check that nothing prevents the door from closing; test the gasket with a paper strip; defrost and reseal. |
| Water on the floor | Clogged defrost drain; loose water-supply fitting; drain pan out of place. | Flush the drain with warm water; tighten fittings; reseat the drain pan. |
| Clicking, gurgling or humming sounds | Normal refrigerant flow, defrost heater, fan and valve operation. | These sounds are normal. Loud rattling usually means the cabinet is not level or something is touching the rear tubing. |
| Condensation on the outside of the cabinet | High room humidity; door not fully closed. | Wipe dry; verify the door seals. Some sweating in very humid weather is normal. |
