If you own an LG LMXS28626S fridge, you may have experienced issues with its defrost system. One common problem is the buildup of ice on the freezer coils, which can lead to reduced cooling efficiency and increased energy consumption. In such cases, installing a defrost heater can be an effective solution. In this article, we will guide you through the process of installing a defrost heater on your LG LMXS28626S fridge.

Why you may need to install a defrost heater on your LG LMXS28626S fridge

As mentioned earlier, the buildup of ice on the freezer coils can cause a variety of problems. If left unchecked, the ice can even lead to a complete breakdown of the cooling system. This can result in spoiled food, water leakage, and other inconveniences. Installing a defrost heater can prevent these issues and ensure that your fridge runs smoothly.

Another reason why you may need to install a defrost heater on your LG LMXS28626S fridge is if you notice that the freezer is not maintaining a consistent temperature. This could be a sign that the freezer coils are not defrosting properly, which can lead to the buildup of ice and other issues. By installing a defrost heater, you can ensure that the coils are properly defrosted and that the freezer maintains a consistent temperature.

Additionally, if you live in a humid climate or if your fridge is located in a humid area, you may need to install a defrost heater to prevent excess moisture from accumulating in the freezer. Excess moisture can lead to the buildup of ice and can also cause the freezer to work harder than it needs to, which can result in higher energy bills. By installing a defrost heater, you can prevent excess moisture from accumulating and ensure that your fridge runs efficiently.

Understanding the components involved in defrosting your fridge

Before we dive into the installation process, it’s important to understand how the defrost system in your LG LMXS28626S fridge works. The system comprises multiple components, including a defrost heater, a defrost thermostat, and a defrost control board. The defrost heater is responsible for melting the ice on the freezer coils, while the thermostat ensures that the heater doesn’t overheat. The control board regulates the timing of the defrost cycle.

It’s important to note that if any of these components fail, it can lead to issues with your fridge’s defrosting capabilities. For example, if the defrost heater stops working, ice will build up on the coils and prevent proper cooling. If the thermostat malfunctions, the heater may overheat and cause damage to the coils. And if the control board fails, the defrost cycle may not occur at the appropriate intervals, leading to ice buildup and potential damage to the fridge.

To ensure that your fridge’s defrost system is functioning properly, it’s recommended to have it inspected and serviced by a professional technician on a regular basis. They can check for any issues with the components and make any necessary repairs or replacements to keep your fridge running smoothly.

  • Replacement defrost heater

It’s important to note that before beginning the installation process, you should unplug the fridge and remove all food and shelves from the freezer compartment. Additionally, it’s recommended to have a hair dryer or heat gun on hand to help remove any ice buildup that may be present on the evaporator coils. Once the installation is complete, allow the fridge to run for at least 24 hours before restocking with food.
