Storm Power Outages And How They Can Affect (or damage) Your Appliances

After the recent ice storm that moved through Middle Tennessee, we’ve seen a noticeable up-tick in service calls involving electronic failures and control board problems in household appliances. Many homeowners across the Nashville area experienced power outages during the storm, and shortly afterward we began seeing refrigerators, dishwashers, washers, and ovens developing new, and sometimes wild, issues.

Since we are approaching severe weather season we thought it would be helpful to take a moment to explain how power outages can affect your appliances, the types of damage they can cause, and a few ways homeowners can help reduce some of the risk.

Why Appliances Sometimes Fail After a Power Outage

Most people assume the problem is the outage itself, but in many cases the real issue happens when the electricity comes back on.

When power is restored, electrical systems can experience sudden voltage spikes known as power surges. These surges can damage the sensitive electronics that modern appliances rely on. Many newer refrigerators, dishwashers, washers, dryers, and ovens contain multiple control boards and sensors that manage everything from temperatures to motor operation.

A power surge can sometimes damage these components instantly, or cause them to fail shortly after the outage.

For homeowners searching for appliance repair after a power outage in Nashville, this is one of the most common causes we encounter.

Common Appliance Problems After Storms or Power Outages

Following storms or electrical disruptions, homeowners may notice appliances that were previously working normally begin to show signs of trouble.

Some of the most common problems we see include:

• Refrigerators not cooling properly after a power outage

• Ice makers suddenly stopping production

• Dishwashers that won’t start or respond to controls

• Washing machines displaying error codes

• Ovens or ranges with blank or unresponsive displays

  
  

In many of these situations, the underlying cause turns out to be a damaged control board or electrical component.

Refrigerators Are Especially Vulnerable

Refrigerators are one of the most common appliances affected by power outages. Because they run continuously and rely on multiple electronic components, even small electrical fluctuations can cause big problems.

Homeowners sometimes call us after a storm saying:

• “My refrigerator is running but not cooling.”

• “The freezer works but the fridge section is warm.”

• “The ice maker stopped working after the power outage.”

  
  

These types of issues often require professional refrigerator repair and diagnostics to determine whether a control board, sensor, or start component has been affected.

Power Fluctuations Can Stress Motors and Compressors

In addition to electronics, sudden power interruptions can also affect mechanical components.

If power cycles on and off quickly, compressors and motors may attempt to restart before pressure has equalized. Over time, this can place stress on start components or cause certain parts to wear prematurely.

While this doesn’t happen every time, it’s another reason appliance issues sometimes appear shortly after storms or electrical outages.

How Homeowners Can Reduce the Risk

While it’s impossible to prevent every outage, there are a few ways homeowners can help protect their appliances from electrical damage.

Install whole-home surge protection.An electrician can install a surge protector at your electrical panel, which helps reduce the impact of power spikes on appliances.

Unplug sensitive appliances during severe storms if possible.If a major storm is approaching and outages are likely, unplugging electronics can help protect them from surges.

Give appliances a few minutes before restarting.After power returns, allowing voltage to stabilize before immediately using appliances can help reduce stress on compressors and motors.
