The Most Commonly Replaced Parts
Several refrigerator parts can be changed without too much difficulty by an individual. Here is a non-exhaustive list, along with explanations of their function and how to replace them.
1. The Door Seal (or Gasket)
The door seal is essential for keeping the cold air generated by the cooling system inside the refrigerator. A worn or damaged seal directly impacts energy consumption and the appliance's performance. Condensation can also form inside. Signs of a defective seal include excessive frost formation, difficulty maintaining a constant temperature, and a feeling of cold air escaping when the door is closed.
- Replacement: Start by gently removing the worn seal. Carefully clean the groove and check for any screws that need to be removed. Then, install the new seal by sliding it into the same groove. Ensure it is well-positioned to guarantee optimal sealing. Check for the absence of folds or poorly adjusted areas that could impair the airtight closure of the door.
2. The Thermostat
The thermostat controls the internal temperature of the refrigerator. If it malfunctions, your food may no longer be stored under optimal conditions. A defective thermostat can lead to overheating or, conversely, excessive cooling.
- Replacement: To access the thermostat, you usually need to open the temperature control box inside the refrigerator. Then disconnect the electrical connectors from the thermostat and remove it. Install the new thermostat and reconnect the cables in the original order. Before plugging the refrigerator back in, ensure the box is securely fastened and that the cables are correctly connected.
3. The Interior Light Bulb
The refrigerator bulb is probably the easiest part to change. When it stops working, it usually just needs to be replaced with a new identical model, ensuring you respect the power and type of bulb recommended by the manufacturer.
- Replacement: Open the door, locate the bulb cover, and remove it. Unscrew the defective bulb by turning it counterclockwise. Gently screw in the new bulb, replace the cover, and close the door. Plug the refrigerator back in to check if the bulb correctly lights the interior.
4. Shelves and Vegetable Drawers
Over time, it's not uncommon to see cracks or chips appear on glass or plastic shelves, as well as on vegetable drawers. Although there is no direct impact on the refrigerator's performance, deformed or broken shelves can pose storage problems and be dangerous.
- Replacement: Most manufacturers offer specific spare parts for each refrigerator model, including shelves and vegetable drawers. Remove the damaged shelf or drawer by simply pulling it out. Then slide the new part into the rails or fittings provided for this purpose. Ensure it is stable before repositioning your food.
5. The Water Filter
Many modern refrigerators have a water or ice dispenser. They are usually equipped with a water filter designed to remove certain impurities and improve water quality. Over time, this filter loses its effectiveness. To ensure proper filtration and avoid bacterial buildup, it is advisable to replace the water filter every six months or according to the manufacturer's recommendations.
- Replacement: Depending on your refrigerator model, the filter is located either inside or at the back. Turn off the water supply and remove the old filter by turning it or pressing a release button. Then install the new filter following the manual's instructions and reconnect the water circuit. Let the water or ice run a few times to purge the air and remove any possible residue.
6. The Freezer or Evaporator Fan
The internal fan plays a crucial role in circulating cold air and maintaining a consistent temperature in the refrigerator. If it breaks down or malfunctions, some compartments may no longer be properly cooled.
- Replacement: Locate the fan, usually accessible by removing the panel at the back of the freezer or evaporator compartment. Carefully disconnect the electrical wires and remove the fan mounting screws. Once the defective fan is removed, install the new fan and reconnect the cables. Ensure the blades are free to turn without obstruction and close the panel.
7. The Defrost System (Heater, Thermostat, or Timer)
Most modern refrigerators use an automatic defrost cycle to prevent excessive frost formation in the freezer compartment. This mechanism relies on several components: a defrost heater, a defrost thermostat, and sometimes a timer.
- Replacement: Detecting the defective part requires a more in-depth diagnosis and a multimeter to test resistances and electrical continuity. If you clearly identify a faulty component, you can order and replace it. Once the freezer door is removed or opened long enough to access the evaporator, the heater is often clipped or screwed nearby. The thermostat is generally found against the evaporator. Proceed carefully with disassembly and ensure each wire is reconnected in the correct place.
8. The Start Relay and Capacitor
The compressor is the heart of the cooling system. It can sometimes stop working due to a defective start relay or capacitor. When these components fail, the compressor no longer starts, leading to a cooling circuit power failure.
- Replacement: Locate the compressor connection box, situated at the back of the refrigerator. The start relay and capacitor are usually attached there. After unplugging the refrigerator, remove the box and replace the defective components. Then carefully reconnect the terminals and ensure the compressor starts working correctly.
Necessary Tools for Replacement
For most common part replacements, a minimum of tools is sufficient:
- Screwdrivers (flat and Phillips).
- Adjustable or socket wrenches for certain bolts.
- Multimeter to test electrical components (useful for checking continuity and voltage of parts).
- Pliers and spare terminals for electrical connections.
- Protective gloves.
In some specific cases, more specialized tools may be needed, such as a crimping tool or soldering iron if soldering is required. Be sure to inquire in advance about the necessary tools for your intervention.
Tips for Extending the Life of Your Refrigerator
While it's reassuring to be able to replace some parts yourself, nothing beats good prevention and regular maintenance to keep your refrigerator in good condition. Here are some practical tips:
