Refrigerator in a cold garage: freezer section thaws in winter while the fridge side seems fine (low-ambient pattern, garage-ready models)

Standard refrigerators are built for indoor rooms. Whirlpool gives about 55-110 F as the recommended range; GE does not recommend installing a refrigerator where it drops below 60 F unless its manual says otherwise. When the room is cold, the control (usually sensing the fresh-food side) thinks no cooling is needed, the compressor runs little or not at all, and the freezer warms. Near 32 F there may be no cooling at all, and GE warns that very cold or very hot rooms can harm the compressor. The fix is a unit rated for the space (garage-ready, often 38-110 F) or a different location, not a new part.

No hazardous work in this diagnosis. Do not install aftermarket heater or garage kits that GE says not to use; follow the manufacturer for each model.
Food safety: a freezer that has been above 0 F for days may have thawed and refrozen food; customer decides with USDA guidance.

Samsung refrigerators: reading display codes, Cooling Off (demo) mode, and forced defrost (Fd) / test mode concepts

Samsung asks owners not to unplug or press buttons to make a code go away, because that erases what the technician needs; only a few power-related codes are cleared by a 60-second power cut. An OF OF or similar display is Cooling Off (demo) mode, not a fault. The test mode is entered by holding a model-specific pair of buttons until the display blanks, then pressing a button to step through modes, one of which is forced defrost (Fd).

LG appliances: Smart Diagnosis (audible and Wi-Fi), display/demo mode and test-mode concepts

LG's Smart Diagnosis sends the appliance's status to the ThinQ app over Wi-Fi or, on older models, as an audible tone the phone picks up near the appliance speaker; the app then shows the result. A fridge that looks normal but does not cool may simply be in display (demo) mode. LG also has service test modes that run fans, compressor and defrost on command; entry varies by model and should come from the service sheet.

Refrigerator preventive service: condenser coil cleaning, condenser fan and door gasket check

Whirlpool says routine condenser cleaning is often not needed in a normal home but recommends inspecting and cleaning every few months where there is dust, grease or pets; older GE manuals say at least yearly. Many current GE models have a sealed 'NeverClean' condenser that needs no cleaning, and some Whirlpool models can only be cleaned by a technician. Know which design you have before you pull the fridge out. Finish with a gasket and door-seal check.
