Safety first

Unplug before removing panels.
Refrigerant/sealed-system work: EPA 608 certified technician only.
Close the water supply before valve work.

How it works

Evaporator behind the freezer drawer back wall; the fan feeds the freezer and pushes air up a duct to the fresh food. Sealed-system work is referral only (EPA 608).

Adaptive Defrost runs only when needed (Abt, Greentoe).

Automatic ice maker in the freezer; no water filter is listed by Abt, and there is no dispenser.

Digital controls in the fresh-food section; demo mode can disable cooling while lights work (Whirlpool product help).

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.
