Cold garages and appliances
Reno's winters are cold; Washoe County's residential design criteria use a 17°F winter design temperature, and NOAA's engineering weather data for the Reno airport records about 123 freeze-thaw cycles a year. Refrigerators and freezers in unheated garages can behave strangely in cold weather. Many refrigerators rely on a thermostat in the fresh-food compartment, and when the garage is cold, the compressor may barely run, letting the freezer section warm up. Some models are designed for garage use and handle cold better. If you keep a refrigerator or freezer in the garage, check the manufacturer's recommended operating temperature range, and use a thermometer to make sure the freezer is staying at 0°F.
Frozen water lines
Washing machines and refrigerator ice makers in garages, on exterior walls or in unheated laundry rooms can have water lines freeze. A frozen inlet valve or supply hose can crack and leak when it thaws. In cold weather, keep laundry areas above freezing, insulate supply lines, and check under the washer and behind the fridge for leaks after a cold snap. If a washer's water supply freezes, don't run it until the line has thawed, and check for leaks.
Dryer vents in winter
In winter, warm, moist dryer exhaust meeting a cold vent can create condensation and lint buildup in the vent. Long vent runs through unheated spaces are most affected. Make sure the vent is insulated where it passes through cold areas, slopes toward the outside so water drains out, and has a flap that opens and closes freely. Snow can block outdoor vents; clear them after storms.
Dry air and electronics
The National Weather Service notes Reno's high-desert setting, and dry air is part of it. Static discharge is common in winter. Modern appliances with electronic controls benefit from surge protection, and control boards can be sensitive to power surges during storms. A whole-home surge protector installed by an electrician adds a layer of protection.
Hard-working ranges and ovens
Holiday cooking and cold weather put ranges and ovens to work. If a gas oven takes a long time to heat, the igniter may be weak. If you smell gas, leave the house and call your gas utility from outside.
Before you hire
Ask Reno appliance technicians what they found and how they confirmed it, whether they carry parts for your brand, what the repair will cost, and how long they warranty their work. For gas appliances, ask whether they'll test for leaks after the repair. Look up the business with the Nevada State Contractors Board if the work involves installation.
Repair or replace
Component repairs such as fans, defrost parts, igniters, pumps and belts are usually worth doing on an appliance in good condition. Sealed-system refrigerator repairs and major control boards on older units often tip the balance toward replacement. Ask for a written price so you can compare.
