Microwave Tripping Breaker in San Fernando? Just Electric Services Has You Covered!

Posted on March 29, 2026 by Just Electric Services

Why Your Microwave Trips the Breaker

Living in San Fernando, California, means dealing with everything from hot summer days to cooler evenings – and sometimes, frustrating electrical issues. A common problem homeowners and businesses experience is their microwave oven repeatedly tripping the breaker. It's more than just a minor inconvenience; it can disrupt your day and potentially lead to further damage if ignored.

Understanding the Cause

Microwaves generate a massive amount of power during operation, far more than most standard household appliances. This surge in electricity isn’t always accommodated by your home's electrical system, particularly older wiring common in San Fernando Valley homes built throughout the 50s and 60s – think charming bungalows in neighborhoods like Burbank or historic residences in Pacoima.

  • Overload: The primary reason is an overloaded circuit. Your breaker is designed to protect your wiring from overheating, and a microwave significantly increases the load.
  • Loose Connections: Older wiring can have loose connections, creating resistance and causing power surges that trip the breaker. This is particularly prevalent in areas with significant rainfall like San Fernando Valley.
  • Faulty Microwave Components: Occasionally, the issue stems from a problem within the microwave itself – a failing magnetron or other component generating excessive voltage.

What You Should Do – And When to Call an Electrician

Before calling a professional, try these steps:

  • Check Your Microwave: Ensure your microwave is operating correctly and not overheating.
  • Don't Overload the Circuit: Avoid using other high-wattage appliances (like space heaters or hair dryers) on the same circuit as your microwave.
  • Reset the Breaker: Flip the breaker fully off and then back on.

However, if you're uncomfortable working with electrical systems, or if the problem persists, it’s crucial to act quickly. Don't risk further damage! That's where Just Electric Services comes in.
