  Your Insignia Refrigerator might not be cooling properly due to several reasons. The door may have been opened too frequently or not closed properly. You may have added a large amount of food recently, so allow time for the new food to cool. The thermostat might be set too warm, so adjust it to a colder setting. The door gasket might not seal properly, so try cleaning it. Finally, if the refrigerator was recently disconnected, allow four hours for it to cool completely.

Why does my Insignia Refrigerator compressor turn on and off frequently?

  Bryan MorrisonAug 28, 2025
  If the compressor in your Insignia Refrigerator is turning on and off frequently, it could be due to several reasons. Make sure the door is closed properly and clean the door seal if it's dirty. A room temperature that is hotter than normal, or recently adding a large amount of food to the refrigerator can also cause this issue, but this is normal. Ensure the thermostat is set correctly and that the refrigerator has at least five inches of clearance from adjacent walls. If the refrigerator was recently disconnected, allow four hours for it to cool down completely.

Cleaning: Clean the interior surface with lukewarm water and a soft cloth.
Initial Cooling: Wait approximately 24 hours after setting the thermostat before placing food inside.
Location: Place on a strong, level floor away from direct sunlight, heat sources (radiators, stoves, amplifiers), and moist areas. Ensure an ambient temperature between 41° F (5° C) and 109° F (42.8° C). Allow the door to swing fully open.

Operation:

Refrigerator Temperature Setting:
- Press the "SET" button to cycle through settings 1 (cold) to 5 (coldest).
- LED indicators show the current setting.
- The default setting is 3.
- Standby Mode: Press and hold the "SET" button for three seconds to enter standby mode (refrigerator and freezer off). The STANDBY LED will light up. Press "SET" again to exit standby.
- If unplugged or power is lost, wait 3-5 minutes before restarting.
- Adjust temperature settings one increment at a time and allow 24 hours for stabilization.
Freezer Temperature Setting:
- Adjust the freezer control knob from MIN to MAX. The "RECOMMENDED" setting is indicated.
- Allow 24 hours for the freezer temperature to adjust and stabilize after changes.
Freezer Compartment Use:
- Place frozen food quickly after purchase.
- Follow package instructions for storage times.
Door Reversal: The door's opening direction can be reversed. This process requires a standard (flat head) screwdriver and a Phillips screwdriver, and assistance is recommended. It involves removing and reattaching hinges, door blocks, hole caps, and plastic bushings to the opposite side.

Energy Saving Tips:

Locate the refrigerator in the coolest part of the room, away from heat sources and direct sunlight.
Allow hot foods to cool before placing them in the refrigerator.
Avoid overloading the refrigerator, which forces the compressor to run longer.
Wrap foods properly and wipe containers dry to reduce frost buildup.
Organize and label food to minimize door openings and search times.

Maintenance Features

Cleaning:
- Wipe the cabinet periodically with a mild detergent and warm water, then dry with a soft cloth.
- Clean the interior with a damp warm cloth soaked in a solution of one quart of lukewarm water to two tablespoons of baking soda solution.
- Keep the door gasket (seal) clean for efficient operation.
- Caution: Do not use gasoline, benzine, thinner, or other similar solvents, or abrasive cleaners, as these can damage the finish.
Defrosting: The refrigerator is frost-free, so manual defrosting of the freezer is not required. Periodic cleaning as described above is sufficient.
