Refrigerator back to proper temp — same day or next day in most cases
Food spoiling because your fridge won't cool or the freezer ices over
When your refrigerator compartment climbs to 50°F but the freezer stays cold, most people assume the worst. In most cases it's a failed evaporator fan motor blocking cold air from reaching the fresh-food section — a same day or next day fix that costs a fraction of a replacement. San Jose homeowners in Saratoga and Cupertino call us constantly for this exact problem. We stock the common motors and carry the repair out in a single visit.
A jammed water inlet valve or a cracked fill tube is behind most ice maker failures in Samsung, LG, and Whirlpool units. Replacing the ice maker assembly is an expensive shortcut that often doesn't fix the root cause. Delta diagnoses the water supply path first — in Palo Alto and Menlo Park kitchens we've saved homeowners hundreds by fixing the valve instead of the module.
Thick frost on the back wall of your freezer means the automatic defrost heater, thermostat, or control board has stopped cycling. Left unchecked it insulates the evaporator coil and the entire unit stops cooling within days. We see this frequently in older GE and Frigidaire side-by-sides across San Jose. A defrost system repair is almost always cheaper than a new refrigerator.
A refrigerator that hums, clicks, then goes quiet usually has a failed start relay — a $15–40 part that's often mistaken for a dead compressor. We test the relay and the compressor independently before quoting anything. In Atherton and Menlo Park, where Sub-Zero and high-end French door units are common, this diagnosis saves homeowners from unnecessary service calls or premature replacements.
