Living in Las Vegas means dealing with triple-digit temperatures, dry air, and nonstop sunlight for months at a time. While you're busy trying to stay cool, your household appliances are also working overtime — and in many cases, failing under the heat.
In this guide, we’ll break down how extreme desert temperatures affect your appliances, what signs of trouble to watch for, and how to protect your equipment before serious damage occurs.
Las Vegas summers aren’t just hot. They’re relentless. And appliances that already generate heat like dryers, ovens, and refrigerators often can’t handle the added stress.
High ambient temperatures affect:
Garages and poorly ventilated laundry areas are the most common danger zones. These spaces easily climb above 110°F, which quickly accelerates internal wear.

Fridges and freezers rely on stable temperatures to maintain cooling cycles. In extreme heat, the compressor runs longer and harder, especially if the unit is located in a garage or next to an oven.
Common issues:
Samsung Support recommends keeping fridges out of direct sunlight and ensuring at least 2 inches of space behind the unit for airflow. GE Appliances also warns that lack of ventilation and ambient heat can confuse the sensor system.

Your air conditioner already works hard in summer. But when the outside temperature reaches 110°F or more, it can run non-stop, stressing the capacitor, blower motor, and control board.
At the same time, many homeowners forget that clothes dryers also need ventilation. If your dryer is installed in a hot garage or closet, the lack of cool air can lead to:
According to Whirlpool, lint buildup combined with poor airflow is one of the top causes of dryer failure in summer.

While washers and dishwashers don’t generate as much heat, they do have motors, pumps, and water inlet valves that can wear faster in high temperatures. In Las Vegas, laundry rooms often have poor airflow, which allows humidity to build up and affect sensor performance.
Signs of summer-related washer issues:
Dishwashers installed next to warm appliances or under sunlit countertops can also overheat, causing misreads in the thermostat or drying cycle failure.

Heat waves can lead to voltage drops or surges from the electrical grid, especially when everyone runs their AC at the same time. Microwaves are sensitive to even small changes in power — and in extreme heat, they often shut down or blow internal fuses.
Ovens may seem immune, but they still rely on sensors, fans, and insulation that degrade faster in summer. Built-in units that don’t vent properly may trip breakers or overheat surrounding cabinets.

Good news: With a few simple strategies, you can reduce the impact of Las Vegas heat and extend the life of your appliances.
Energy.gov recommends checking appliance filters, coils, and drains before each summer. Consumer Reports adds that preventing overheating is cheaper than replacing a burned-out unit.

High outside temperatures make the compressor run longer and harder. Poor ventilation and sunlight exposure can worsen the problem. Clean coils and move the unit if needed.
It’s possible, but only if the garage is well-ventilated and the dryer vent is kept clean. Otherwise, the heat can cause overheating and fire hazards.
If you’re not using them, yes — especially microwaves, toasters, and coffee makers. This reduces load on the circuit and prevents surge damage.
Ideally once before and once after summer. Filters, coils, and thermostats should be checked seasonally in desert climates like Las Vegas.
