Every refrigerator requires breathing space to function properly. If it does not get enough room for air circulation, the system will heat up and work twice as hard to remain cool. This will also increase your electricity bills and shorten the lifespan of your refrigerator.
Rear Clearance – Allow between one to two inches of space at the rear of the refrigerator for proper airflow. Top Clearance – Ensure there is a minimum of one-half inch to one inch of clearance on top of the unit.
This heat is released outside of the fridge, so you need to make sure you allow space for proper ventilation. Leave at least 7 or 8cm of space between the back of the fridge and the wall to allow for the fridge's plug, and for ventilation. You should also aim for a few cm around the top and sides of the fridge.
A minimum of 200 cm2 of ventilation must be provided at both the top and the bottom of the cabinetry to allow correct airflow.
The following are general minimum clearances for refrigerators: 1/8" up to 1" inch of clearance on each side. 1" on the top (this is above the case, not the hinge). 1" to 2" in the back.
Having too little space can greatly impact on the performance and life of your fridge, such as minimising over-heating.
Airflow is the most important driving force in the efficiency of refrigeration. Always remember hot air rises and cold air falls. In the Kenmore 253 upright, air flows from the top, down the back side, and up the front side. If for any reason airflow is disturbed, uneven refrigeration occurs.
No not normally, a compressor fridge runs rather like a domestic fridge as it compresses a contained gas and needs only a modest amount of airflow that can be internal depending on design.
With a tape measure, find the width, depth and height of the space where the fridge will be placed. Remember to leave 25 mm of free space around the top, back and sides to allow for the heat produced during refrigeration to escape.
When contemplating enclosing a standard appliance into furniture it is vitally important that the furniture is designed correctly to allow proper ventilation for the fridge. More specifically, you cannot put a fridge into a normal, unmodified cupboard – it will not work!
Do not install the refrigerator near an oven, radiator or other heat source because that may cause it to work harder to stay cool. The fridge must be near an electrical outlet. If your fridge has ice and water dispensers, it must also be near a water line.
Refrigerator Function in Cold Temperatures
When the ambient temperature is below 60ºF, it takes more energy to make the refrigerant boil and change into a vapor. And the energy consumption increases with the decreasing temperature until at 32ºF, there's no cooling capacity at all.
Surround the refrigerator with cabinets and/or matching panels to cover the top and sides. Choose a finish or a trim kit that matches the cabinetry. Pro: Building cabinetry around the refrigerator requires no demolition, making it a relatively easy and inexpensive option.
Blocked Vents
Overfilling your fridge and freezer with food can block critical vents and prevent your refrigerator from cooling properly, so to fix this, you'll want to organize your food in the fridge in a way that does not obstruct proper air circulation. Less commonly, your vents may have frozen over.
For full height appliances there should be a 200cm² slot in the plinth and the top of the built-in housing, along with a hole beneath the appliance. This will provide adequate ventilation for any built-in refrigeration appliance.
When a fridge is placed on a carpeted floor, it proves to be an obstruction for proper airflow. The refrigerator requires adequate space and airflow to function properly. Without proper air circulation, the fan, the cooling system and the compression of the fridge won't be able to work properly.
There should also be a space of 1-2 inches on the back of the fridge to allow proper air circulation. Newer refrigerator models have their coils at the back so leaving space is imperative to have proper ventilation. On each of the sides, there should be a space of 1/2-1 inch.
Without proper ventilation, you can damage the fridge and cause it to consume more energy. You'll need at least a quarter-inch gap for ventilation on the sides of the refrigerator as well as one inch on the back and top.
A minimum of 200cm2 ventilation opening must be provided at both the top and the bottom of the cabinetry to allow for appropriate air flow.
Although power outages happen in the blink of an eye, refrigerated food will not instantly go to room temperature. In fact, depending on the refrigerator model and a few other factors, your refrigerator can keep its cool for about four hours, while a freezer could stay cold for up to 48 hours.
Proper ventilation of the compressor room is essential for heat dissipation. The amount of ventilation air required depends on the compressor's size and whether it is air-cooled or water-cooled.
Leave the door open and allow to air out for several days. Stuff both the refrigerator and freezer with rolled newspapers. Close the door and leave for several days. Remove paper and clean with vinegar and water.
Fridges need some breathing space around them to let heat dissipate.

Locate the vents in the freezer and refrigerator compartments and ensure nothing is blocking the airflow. If vents are blocked, airflow will decrease. Temperature and moisture issues may arise due to blocked vents.
