One common issue that many Frigidaire refrigerator owners encounter is a faulty defrost heater. The defrost heater is a crucial component that helps prevent frost buildup in the freezer section of the refrigerator. When this heater malfunctions, it can lead to excessive ice accumulation, which can affect the refrigerator’s cooling performance. Fortunately, replacing a defrost heater in a Frigidaire refrigerator is a relatively simple task that you can do on your own. In this step-by-step guide, we will walk you through the process of replacing a defrost heater in your Frigidaire refrigerator.
