Understanding the Basics
Before we dive into specific causes, it’s important to grasp the basic mechanics of how refrigerators function and their electrical requirements. Refrigerators typically operate on a standard household voltage of 120 volts. When you plug in your fridge, it draws a significant amount of electrical current, especially when the compressor kicks on. This surge in power can sometimes exceed the limits of your circuit breaker, resulting in a trip.
Common Causes for Circuit Breaker Trips
Several factors can contribute to your refrigerator tripping the breaker. Understanding these potential issues can help you diagnose and fix the problem effectively.
1. Overloaded Circuit
One of the most common reasons for a refrigerator tripping a breaker is an overloaded circuit. If your fridge shares the same circuit with other appliances, the combined electrical demand can exceed the circuit’s capacity.
Signs of Overloaded Circuits
- Flickering lights when the refrigerator kicks on.
- Other appliances in the same circuit frequently shutting off.
To resolve this, consider the following steps:

The start relay is a component that helps the compressor start. If it becomes faulty, it can create an electrical short, causing your breaker to trip.
Indicators of a Faulty Start Relay
- The refrigerator makes a clicking sound when attempting to start.
- The compressor runs inconsistently or not at all.
To check this component:
– Locate the start relay on the compressor (often at the back of the unit).
– Test it with a multimeter for continuity. If it shows no continuity, it’s time to replace it.
3. Damaged Compressor
The compressor is the heart of your refrigerator. If it has a short circuit or internal failure, it can lead to excess current draw, causing the breaker to trip.
Symptoms of a Failing Compressor
- The refrigerator runs excessively but struggles to maintain temperature.
- You hear unusual sounds, such as grinding or rattling.
If you suspect a bad compressor:
– Inspect the compressor for physical damage or oil leaks.
– A faulty compressor often requires professional diagnosis and repair.
4. Faulty Power Cord
The power cord is another potential culprit. Wear and tear, heat, and moisture can damage the insulation, exposing the wires and leading to short-circuits.
Identifying Power Cord Issues
- Look for fraying, burns, or visible damage on the cord.
- Check for improper connections at the plug.
If you find damage, replace the power cord immediately to prevent further issues.
5. Dirty Condenser Coils
Although this issue may seem unrelated, dirty condenser coils can actually cause your refrigerator to overheat, which can lead to increased electrical draw.
Effects of Dirty Coils
- Increased energy consumption leading to expensive bills.
- Overheating components, including the compressor.
To clean the coils:
– Unplug the refrigerator.
– Use a vacuum or coil brush to remove dust and debris from the coils.
Diagnosing the Problem
Identifying the exact reason for your refrigerator tripping the circuit breaker can often be a process of elimination. Here’s a simplified approach to diagnose the issue effectively.
1. Observe the Symptoms
Take note of what occurs before the breaker trips. Is the breaker tripping after extended use, or does it happen randomly?
2. Inspect the Electrical Setup
Check the circuit’s amperage rating. Most refrigerators require a minimum of 15 to 20 amperes; a lower rating could result in tripping.
3. Check for External Factors
Evaluate if any other devices have been plugged into the same circuit. A sudden power surge in another appliance may be causing the disruption.
Professional Help vs. DIY Solutions
When troubleshooting refrigerator issues, determining when to enlist professional help is critical.
When to Call a Professional
You may want to call a technician if:
