Monsoon Season: Protecting Your Appliances from Power Surges

Storm Season Protection

Arizona's monsoon season, typically July through September, brings dramatic thunderstorms and lightning. While spectacular to watch, these storms pose significant risks to your home appliances through power surges.

Understanding Power Surges

What Causes Surges:

• Lightning strikes (direct or nearby)
• Utility grid switching
• Power restoration after outages
• Large motor startups in your home

How Surges Damage Appliances:

• Overwhelm electronic components
• Degrade circuits over time
• Burn out control boards
• Damage compressors and motors

Most Vulnerable Appliances

High Risk:

• Refrigerators with electronic controls
• Modern ranges with digital displays
• Dishwashers with electronic panels
• Wine coolers with precise controls

Why Luxury Appliances Are More Vulnerable:

• More electronic components
• Sophisticated control systems
• Sensitive temperature sensors
• Connected/smart features

Protection Strategies

Whole-House Surge Protection

Best overall protection:

• Installed at electrical panel
• Protects entire home
• Handles large surges
• Cost: $300-600 installed

Point-of-Use Surge Protectors

Additional protection layer:

• Plug-in units at each appliance
• Choose units rated for appliances
• Look for joule rating over 1000
• Replace after major surges

Uninterruptible Power Supply (UPS)

For critical electronics:

• Provides battery backup
• Conditions power
• Best for sensitive equipment
• Consider for wine storage

Appliance-Specific Recommendations

Refrigerators

• Use dedicated circuit
• Install surge protector
• Consider UPS for high-end units
• Unplug during severe storms (if safe)

Ranges and Ovens

• Surge protect if electronic controls
• Hard-wired units need panel protection
• Check manufacturer recommendations

Dishwashers

• Often overlooked for protection
• Electronic models need surge protection
• Can share protected circuit with disposal

During a Storm

If a Storm is Approaching:

• Save any programmed settings if possible
• Consider unplugging sensitive electronics
• Close refrigerator doors and minimize openings
• Avoid using major appliances

After a Power Surge:

• Don't immediately turn everything on
• Wait for power to stabilize
• Check appliances one at a time
• Look for error codes or unusual behavior

Signs of Surge Damage

Watch for after storms:

• Error codes on displays
• Appliance won't turn on
• Erratic behavior
• Burning smell
• Tripped breakers

Insurance Considerations

Document your appliances:

• Keep purchase receipts
• Photograph serial numbers
• Note installation dates
• Review homeowner's policy

Professional Assessment

After significant storms:

• Have surge-sensitive appliances checked
• Look for hidden damage
• Verify proper operation
• Test temperature accuracy
