Fridge runs nonstop: Jammed tight at the back or the top? Pull it out a bit. If it's still going all day, the coils probably need cleaning, or the condenser fan's on its way out. See
refrigerator repair.
Old range burner won't light: Give the igniter a scrub and drop the cap back on straight. Really old range with a standing pilot? Maybe the pilot's just out, or plugged up. See
range repair.
Oven heats slowly: Gas with a glow bar? Weak igniter, that's the classic. Electric? Look at the bake element, you can often see where it burned through. See
oven repair.
Shared washer leaking: Front-loader door boot torn, a pump going bad, or a hose that worked loose. Out in a garage a slow leak can go on for weeks before anybody notices. Peek under it now and then. See
washer repair.
Garage dryer takes forever: That squashed foil hose again. Replace it with rigid or semi-rigid duct. Hose is fine? Then it's the element or the gas valve coils. See
dryer repair.
Dishwasher won't drain: Filter first. Then the hose under the sink, which loves to get kinked by stuff stored down there. Then the pump. See
dishwasher repair.
