Faults: a quiet fridge that won't cool, a dispenser stuck on the door, or frost building in the freezer. Do: check the start relay hum and vacuum the rear coils clean. Don't: keep slamming a jammed dispenser flap — you'll crack the door auger housing.

Faults: a lid-lock error that won't start, no spin, or it stops mid-cycle and won't drain. Do: check the lid-lock latch clicks shut and clear the drain-pump filter. Don't: override or tape down the lid switch — it's the safety that stops the drum during a spin.

Faults: runs but no heat, a loud thumping drum, or it stops after a few minutes. Do: empty the lint screen and clear the vent run all the way to the wall. Don't: keep running it with a thumping drum — worn glides and rollers can score and crack the bulkhead.

Faults: a blinking "Clean" light fault code, won't drain, or dishes left cloudy. Do: count the blink pattern, clean the filter, and run a hot rinse with fresh rinse aid. Don't: ignore standing water at the bottom — a stalled drain pump can leak past the seal.

Faults: a burner that won't heat, a gas igniter that clicks but won't light, or a burner stuck on high. Do: keep the igniter ports dry and reseat any plug-in coil element firmly. Don't: leave a burner stuck on full power — a welded infinite switch is a burn risk, so cut the breaker.

Faults: an F7 stuck-keypad code, won't reach temperature, or a glow-bar that won't ignite the gas. Do: note the F-code and cut power for a minute to clear a stuck touchpad. Don't: use self-clean to mask a heating fault — the heat spike often finishes off the igniter or control board.
