Most freezer breakdowns trace back to a short list of parts: the defrost system, the evaporator or condenser fan, the thermostat or temperature control, the door gasket and, less often, the sealed system. We pull these listings from public business data, remove closed businesses, parts stores and unrelated trades, and put companies that mention freezers and refrigeration at the top.

Food Safety When a Freezer Warms Up
Keep the door closed. Every opening lets cold air out. Put an appliance thermometer inside so you know the real temperature, and move food to another freezer or a cooler with ice if the repair will take longer than the freezer can hold.
During a power outage, an unopened refrigerator keeps food cold for about 4 hours; a full freezer holds its temperature for about 48 hours and a half-full freezer for about 24 hours if the door stays shut. Source: USDA FSIS - A Consumer's Guide to Food Safety: Severe Storms and Hurricanes
An appliance thermometer is the most reliable way to know the temperature; keep one at the front of both the refrigerator and the freezer and check them at least weekly. Source: FDA - Are You Storing Food Safely?
