Refrigerator: coils, seals, and temperatures
Unplug, brush and vacuum the coils, wipe the door seals with warm soapy water, and verify 37°F and 0°F with a thermometer. Change the water filter if it is six months old.
Dryer and vent: the safety item
Pull the lint screen and wash it (fabric softener film clogs the mesh invisibly), then check the outside vent hood for lint and free flap movement. The full vent run itself is a yearly pro cleaning.
Washer: hoses, filter, and a hot empty cycle
Inspect supply hoses for bulges and rust, clean the pump filter on front-loaders, wipe the door boot, and run a hot empty cycle with a washer cleaner or a cup of vinegar.
Dishwasher: filter, spray arms, and screens
Remove and rinse the filter, spin the spray arms to check they move freely, and look for mineral crust on the arm holes, the Cheatham County hard-water signature.
Kitchen small checks
Clear the microwave vent filter, check range burner caps sit flat, run the disposal with cold water and ice cubes, and test every appliance's clock and display for storm-season surge damage.
