Freezer or refrigerator coils are located in one of two places, depending on whether you are referring to the internal evaporator coils or the external condenser coils:
Cleaning your freezer's condenser coils improves energy efficiency and prevents compressor burnout. Turn off or unplug the unit, and locate the coils (usually on the back, or along the bottom behind the front toe grill). Gently vacuum away dust, then use a coil brush to remove stubborn buildup.
Types of Common Freezer Problems
Whether located at the University or in your home, the refrigeration coils on all refrigerators and freezers must be regularly cleaned in accordance with manufacturer's instructions to ensure safe and efficient operation.
Locate the coils, which live either at the bottom of the appliance or in back of it. Older models have exposed coils mounted on the back of the refrigerator. Newer models place the coils at the bottom behind a toe space panel (like the model below) or at the back behind a rear access panel.
The coils are usually found at the back of the appliance or near the bottom. They are easily identified as they can sometimes look like wire racking covering the rear of the fridge.
The compressor, coils and control board are the most expensive repairs. Your fridge's brand, model and size, plus your location, will impact repair costs. If your refrigerator is more than 6 years old and it will cost you more than half its original price to repair it, consider replacing it instead.
If refrigerator coils are not cleaned, dust and debris build up, preventing heat from escaping and causing the unit to work significantly harder to maintain temperatures. This leads to increased energy consumption (up to 35% more), higher electricity bills, warmer temperatures, and potential premature failure of the compressor.
Upright freezers typically last between 10 to 15 years. With excellent care and regular maintenance, some models can stretch up to 20 years. The compressor and the door seals are the most common parts to wear out first.
Yes, you can clean evaporator coils yourself. It is a manageable DIY task involving turning off the power, accessing the coil, cleaning with a brush/no-rinse spray, and cleaning the drain pan. This improves AC efficiency and saves money, but requires care to avoid damaging delicate aluminum fins.
A standard fridge freezer lasts an average of 10 to 15 years. However, longevity varies by style: standalone units typically hit 10–12 years, while built-in or high-end models can stretch to 15–20 years. Complex smart features often reduce overall lifespan due to wear.
Putting a penny (or any coin) in the freezer is an easy trick used to check if your freezer lost power while you were away, and whether your frozen food is still safe to eat.
It is generally worth repairing a freezer if it is less than 5–7 years old, the repair cost is under 50% of a new unit, or the issue is minor (e.g., faulty seals or thermostat). For older units, particularly budget models over 10 years old or those with broken compressors, replacement is usually more cost-effective.
Watch for these signs of dirty condenser coils:
🧹 By vacuuming the coils once or twice a year, you can help reduce energy usage and prevent costly repairs.
Replacing an AC condenser coil typically costs between $1,500 and $4,200, including the part, labor, and refrigerant handling. Prices vary significantly depending on your system's tonnage, coil material, and refrigerant type.
Frequent breakdowns - In case of frequent breakdowns, it is often better to replace the device. 3. The age of your appliance – Since freezers have a lifespan of 10 to 15 years, it is best to replace your appliance if it's more than 10 years old.
GE and Frigidaire are widely considered the best brands for upright freezers. They are praised for their durability, energy efficiency, and "garage-ready" designs that withstand extreme temperature changes.
To quickly check if your freezer is broken, use the water bottle test: freeze a half-filled bottle of water, then store it upright. If the ice melts and refreezes at the bottom, your freezer is losing power intermittently.
Yes, you should always unplug your refrigerator or turn off its circuit breaker before cleaning the coils. This is primarily a safety precaution to protect against electrical shock and to prevent the condenser fan from blowing dust in your face while you work.
Compressor Replacement
As you might expect, the compressor is one of the most important parts of the refrigerator so it is one of the most expensive. While you can purchase the part yourself, it's not recommended that you try to replace it on your own.
No matter how tidy your fridge is, there's probably something in there that should be thrown out. Examples include condiments that have been opened for over 12 months, leftovers older than 4 days, and fresh meat and seafood past their prime.
The Amish keep food cold using a variety of off-grid methods, tailored to the strictness of their local church district. Common practices include:
Which refrigerator brand is most reliable? All three of the appliance experts we spoke to for this roundup said Whirlpool and LG were the most reliable refrigerator brands due to their durability, reliability and ease of repairs. Samsung and GE were also mentioned by our experts as high-quality fridges.
Bottom-freezer refrigerators should be repaired within seven years and considered for replacement after that. Top-freezer refrigerators should be repaired within three years, considered for repair within three to six years, and replaced if older than seven years.
