Schedule
Appliance maintenance schedule
42 tasks across 12 appliances, sorted by how often to do them rather than by machine. Each one names the specific service call it prevents, because a maintenance list without that is just chores.

That 25 hours covers all 12 appliance types on this page and assumes weekly use. Almost nobody owns all of them — the per-appliance table further down gives your real number, and a standard kitchen and laundry is a fraction of it.
The 8 that are about safety, not performance
Everything else on this page saves you money. These prevent a fire, a flood, or an injury. If you only ever do part of this schedule, do this part.
Clear the lint screen
Restricted airflow, two-cycle drying, and the heat build-up that sits behind most dryer failures and every dryer fire.
Degrease the mesh or baffle filters
Weak extraction that gets misdiagnosed as a failed motor, and a grease-saturated panel sitting directly above a gas flame.
Disconnect and clean the entire vent run and exterior hood
Blown thermal fuses, drying that takes two cycles, and dryer fires. The US Fire Administration counts roughly 2,900 clothes dryer fires a year in residential buildings, with failure to clean the single leading cause.
Inspect the fill hoses and replace them at five years
A burst fill hose, which is the most expensive single water-damage event in a typical home and happens with nobody there.
Have the gas connection leak-checked
The one item on this entire page with immediate life-safety consequences.
Manually defrost once frost passes a quarter inch
Lost capacity and a compressor working against an insulating layer of ice. Puncturing an evaporator tube while chipping destroys the sealed system outright.
Replace flexible foil duct with rigid or semi-rigid metal
The restriction that makes every other dryer failure more likely, and the accumulation that turns a vent into a fire load.
Fit the anti-tip bracket on a freestanding range
A range tipping forward under weight on an open oven door. The bracket normally ships in the box, but fitting it is an install step that is easy to skip — check rather than assume.
The dryer vent is the one people underestimate. Lint is highly combustible, and it accumulates in the duct rather than on the screen — which is why a dryer that suddenly needs two cycles to dry a load is telling you about a fire risk, not about its heating element. Clean the full run annually, and replace ribbed foil ducting with rigid metal the first chance you get.

Every load, every use
Habits rather than tasks. None of these takes more than thirty seconds, and between them they prevent more service calls than everything below.

The filters and seals that silt up on a scale of weeks. Roughly twenty minutes for the whole kitchen if you do them together.

Every three months
Jets, screens and traps — the things you cannot see failing until performance drops.

Twice a year
Coils, drains and door seals. This is the tier that decides whether a refrigerator reaches the top or the bottom of its expected lifespan.

| Refrigerator | Dollar-bill test every door seal | Constant running, frost build-up, and a compressor working against a permanent leak of warm room air.Refrigerator Door Seal Failing→ | 5 min |
| Refrigerator | Change the water filter | Small hollow ice cubes, slow dispensing, and an inlet valve strained against a restriction it was not designed for.Ice Maker Slow or Making Small Cubes→ | 5 min |

Your actual time budget
The same tasks counted per machine, heaviest first. Add up only the appliances you own — that is the real number, and for most homes it is under six hours a year.

| Range Hood | 4 | 3 hr 42 min | Degrease the blower wheel itself |
| Washer | 5 | 3 hr 2 min | Inspect the fill hoses and replace them at five years |
| Dishwasher | 4 | 2 hr 32 min | Clear every spray-arm jet with a toothpick |
| Freezer | 4 | 2 hr 30 min | Manually defrost once frost passes a quarter inch |
| Garbage Disposal | 3 | 2 hr 4 min | Grind a tray of ice cubes with coarse salt, then citrus peel |
| Dryer | 4 | 2 hr 2 min | Disconnect and clean the entire vent run and exterior hood |
| Microwave | 3 | 1 hr 58 min | Wash the grease filters on an over-the-range unit |
| Oven & Range | 5 | 1 hr 55 min | Verify oven temperature with a thermometer and recalibrate |
| Ice Maker | 2 | 1 hr 36 min | Descale and sanitise an undercounter machine |
| Refrigerator | 5 | 1 hr 30 min | Flush the defrost drain |
| Trash Compactor | 2 | 1 hr 20 min | Wipe the drawer track and rollers clean |
| Wine Cooler | 1 | 20 min | Vacuum the condenser or heat-sink fins |
Times are realistic working estimates including getting the tools out, and the yearly figure assumes weekly use for anything on the every-use list. One-off installation tasks count as zero per year because they never come round again — which is exactly why they are worth doing properly the first time.
Why this works on some failures and not others
What maintenance genuinely prevents
Three failure families, and they are the common ones. Airflow: blanketed condenser coils, a lint-packed dryer vent, a grease-loaded hood filter, a refrigerator with no clearance behind it. Drainage: a blocked defrost drain, a dishwasher filter nobody knew existed, a washer pump filter holding a coin. Seals: a door gasket that stopped sealing two years ago and has had the compressor running ever since.
Refrigerators that die before year eight almost always failed for an airflow reason. Dryer failures cluster around restricted vents, and a blown thermal fuse is a symptom of one rather than a fault in itself. Washer bearing failures follow worn dampers and an out-of-level installation. Every one of those is on the schedule above.
What it does not prevent
A control board failing at year twelve. A magnetron reaching the end of its life. A compressor that was marginal from the factory. Electronics fail on their own schedule, and no amount of cleaning changes that — anyone promising otherwise is selling something.
The honest claim is narrower and more useful: maintenance moves an appliance from the bottom of its expected lifespan to the top of it, and it removes most of the inconvenient mid-life service calls along the way. When the electronics do eventually go, check the appliance’s current value in the Blue Book before authorising the repair.

Maintenance is for the next fault. These are for the current one.
