Why does my Kelvinator Refrigerator run constantly?
- B
  Brian HughesAug 22, 2025
  If your Kelvinator Refrigerator runs all the time, it could be due to several reasons. Not enough air circulation around the cabinet, or restricted air circulation, could be the issue, so relocate the cabinet or provide proper clearances and make necessary adjustments. A poor lid seal can also cause this, so relocate the cabinet or provide proper clearances and make necessary adjustments. The refrigerant charge might be off, either undercharged or overcharged, so check, evacuate, and recharge with the proper amount. A room that's too warm can also make the unit run constantly, so ventilate the room. Finally, the cold control might be faulty; if it allows the unit to operate all the time, replace it.

How to reduce noise from a Kelvinator R-404A Refrigerator?
- J
  johnstonkatherineAug 28, 2025
  If your Kelvinator Refrigerator is operating noisily, several factors could be the cause. Loose flooring or a floor that isn't firm can create noise, so tighten the flooring or brace the floor. Tubing contacting the cabinet or other tubing can also cause noise, so move the tubing. If the cabinet isn't level, level it. A fan hitting the shroud can also generate noise, so move the fan blade. Lastly, a mechanically grounded compressor can cause noise, so replace the compressor mounts.

What to do if my Kelvinator Refrigerator cycles on overload?
- L
  Lisa LandryAug 31, 2025
  If your Kelvinator Refrigerator cycles on overload, it could be due to a few reasons. A broken relay can cause this, so replace the relay. A weak overload protector can also be the culprit, so replace the overload protector. Low voltage can also lead to cycling on overload, so check the outlet with a voltmeter to ensure it reads 115V (plus or minus 10%) under load. Also, check if too many appliances are on the same circuit or if an extremely long or undersized extension cord is being used.
