Winter in Norman, Oklahoma is rough on appliances. One week you’re tailgating at Gaylord Family-Oklahoma Memorial Stadium in sunshine, and the next a cold front rolls in with ice, sleet, and wind chills dropping into single digits. The shift hits fast. Lake Thunderbird freezes, power flickers across Cleveland County, and suddenly every furnace, heat pump, and water heater is working overtime to keep your home safe and warm.
Those temperature swings, along with frozen condensate lines, OG&E brownouts, and the ever-present Oklahoma red clay dust, are the main reasons we see the same appliance problems every winter. These issues show up in almost every neighborhood, from Brookhaven to Hall Park, east Norman, downtown, and rural county homes.

Clothes Dryer: No Heat or Long Dry Times
Frozen exterior vents are extremely common during ice storms.
Common Causes & Parts
- Blown thermal fuse
- Burned-out heating element

Garage Refrigerator Not Cooling
Most standard refrigerators are not designed for unheated garages. When the ambient temperature drops below 38°F, the internal thermostat shuts down cooling and the freezer warms up.
Fixes That Work in Norman
- Install a garage heater kit (Whirlpool W10225581 works on most models)
- Add a 60–100W bulb inside on a timer
- Move fridge indoors for winter
- Upgrade to a true garage-ready model (GE GTE18GTNRWW is a strong option)
Typical installation (heater kit): $149 labor + part
