Refrigerator water filter leaks at the housing, or the new filter will not lock in

Nearly all filter-area leaks after a change come from the cartridge itself: the shipping cap left on, a stretched or rolled O-ring, a cartridge that is not turned fully home, or a non-matching aftermarket filter. Only after those are ruled out is the housing (head) suspect, and a cracked housing is a parts repair. Always shut the water off before pulling a filter that is leaking.

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.
