Refrigerator habits that make it work harder, like setting it colder than it needs to be, boxing it in without air space, placing it next to the oven or keeping it in a hot garage, keep the compressor running longer than it should. A setting in the recommended range and room to shed heat take much of that load off.
Mistakes at a glance
| Habit | What it leads to | Do this instead |
|---|---|---|
| Turning the control to its coldest setting | Longer run times and food that can freeze on the shelves | Aim for 35°F to 38°F in the fridge and 0°F in the freezer |
| Sliding it tight against the wall and cabinets | Heat from the condenser has nowhere to go | Leave the air space the installation guide calls for |
| Stacking boxes and trays on top of the fridge | Crowded top clearance on models that need it | Keep the space above the case clear |
| Placing it next to the range, dishwasher or a sunny window | Extra heat it has to fight all day | Keep it away from heat sources and direct sun |
| Keeping a standard fridge in an uninsulated garage | Running outside its rated room-temperature range | Keep standard models indoors, or check the manual's range |
| Never cleaning the condenser coils on an older model | Less heat removed, so the system runs longer | Clean the coils as the manual directs |
| Ignoring a door seal that leaks | Warm, humid air leaking in all day | Fix door habits and replace a damaged gasket |
The ones that matter most
Setting it colder than it needs to be
Colder isn't better past a point. The U.S. Department of Energy's Guide to Kitchen Appliances recommends keeping the refrigerator between 35°F and 38°F and the freezer at 0°F. Setting the control to its coldest position makes the system run longer to hold a temperature lower than food needs, and it can freeze lettuce and milk near the vents. Use an appliance thermometer to check, since the numbers on the dial aren't degrees.
Boxing it in
The condenser has to release the heat it pulls out of the cabinet. GE Appliances lists typical minimum air clearances of 1/8 inch to 1 inch on each side, 1 inch on top and 1 to 2 inches at the back, and says proper airflow is critical. Other brands publish different numbers, so the installation guide for your model is the one to follow. Pushing a fridge flush into a tight cabinet, or filling the space above it with cereal boxes and serving trays, takes away that air space.
Heat sources and hot garages
Every degree around the fridge is one more degree it has to fight. The DOE guide says to keep refrigerators and freezers away from heat sources such as ovens, dishwashers and direct sunlight. Maytag's location guidance gives a room-temperature range of 55°F to 110°F for its refrigerators and says garages are not recommended for standard refrigerators unless the space is insulated and climate-controlled. San Antonio summers make that matter. If a second fridge or freezer lives in the garage, read the manual's range first; the same limits apply to freezers kept in San Antonio garages.
Skipping coil cleaning
The DOE guide recommends keeping condenser coils clean on older models. Dust on the coils works like a blanket over the part that is supposed to release heat. Some newer designs don't need routine coil cleaning, so follow your manual.
A leaking door seal adds load as well. See refrigerator door habits that hurt the seal and hinges.
Signs it's already caused a problem
- The fridge runs almost nonstop, especially on hot afternoons
- The sides or the front grille feel much warmer than usual
- Food freezes near the vents while the door shelves feel warm
- The thermometer creeps above 40°F during summer even with the setting unchanged
- The compressor clicks on and off very often, or you hear a new loud hum
If it keeps struggling after you correct the setting and placement, book a refrigerator repair visit to check the fans, coils and sealed system.

Habit to keep: Set it to 35°F to 38°F, and give it air space away from heat.
