![]() ![]() Residential code allows 20 amps per circuit (source). Overloaded Circuit: An overloaded circuit occurs when too many amps are running through the same wiring.Figuring out where the problem lies can save property and life. Circuit breakers trip to stop the flow of electricity and indicate that something is going wrong. It is important to have an understanding of what is happening in the circuitry. What Is Happening in My Circuitry to Cause Tripping? It is the powerhouse of the appliance and the most expensive component to replace. Refrigerator Compressor: The compressor works as both a motor and a pump, moving refrigerant throughout the system coils to cool the temperature in the fridge. It is attached to a timer and thermostat that work to regulate the temperature and cycling of the defrost heater and compressor ( source). Refrigerator Defrost Heater: The defrost heater is a resistance element located in the evaporator compartment to melt ice built up on the coils of the refrigerator. They protect someone from electric shock should a short circuit or ground fault occur. These outlets are used in bathrooms and other areas where water is present for protection against electrocution. The appliance is plugged into the outlet, and when even a few amps of surge are detected, the circuit within the outlet will trip. GFCI Outlet: A Ground Fault Circuit Interrupter works like an ultra-sensitive circuit breaker. The ground wire is incredibly important because, without it, the entire appliance can become one big shock hazard ( source). This ground wire will take the 120 volts if the hot wire shorts, causing an extremely high current that trips the breaker. The third prong connects the ground wire, which is simply attached to the metal casing of the appliance. These run through the 2 thinner prongs on power cords. The hot wire carries the 120 volt current to your appliance and the neutral wire serves as the return path in the circuit. ![]() Wiring Basics: Three electrical connections make up the standard appliance wiring that connects to your home’s electrical system. Whether from constant, slow heating, or from a sudden power surge, the circuit is designed to break the current when it is overloaded. I will start at the breaker box.Ĭircuit Breaker: Circuit breakers are attached to all of the wiring in a building or home and act as safeguards against power surges and other electrical issues. Let’s start our discussion with the mechanical and electrical components involved in circuit breakers, outlets, and basic refrigerator mechanisms that can be involved in circuit breaker tripping. And finally, we will walk you through a step-by-step troubleshooting guide and give solutions to the most common reasons your refrigerator is losing power. Next, we will discuss just what the main circuitry problems are telling you. This article will first outline the mechanics of circuit breakers, outlets, and refrigerator components. Why a refrigerator keeps tripping a breaker? The primary causes of a refrigerator repeatedly tripping a breaker are:Īll of these problems can cause fires and/or electrocution if not properly addressed. Obviously, a reoccurring problem like this needs attention. A refrigerator will lose power from a tripped breaker, sometimes for hours before you realize it. ![]()
