Every appliance has a number. Knowing it changes how you read a breakdown: a failure at year 6 is a repair, the same failure at year 14 is usually a goodbye. Here is what each major unit actually lasts, the signs that mean replace, and the maintenance that buys you extra time.
Average Lifespan by Appliance
These are real-world averages from the field, not factory brochures. Water hardness, run frequency, and how the unit is loaded all move the number.
- Refrigerator: 13 to 17 years. Built-in luxury (Sub-Zero) can pass 20 with a sealed-system rebuild.
- Dishwasher: 9 to 12 years. Premium units reach 12 to 15; mainstream brands run shorter.
- Clothes washer: 10 to 13 years. Front-load bearings are the usual end-of-life failure.
- Clothes dryer: 11 to 14 years. The drum outlasts the rest; heating elements and rollers wear first.
- Electric range / oven: 13 to 15 years.
- Gas range / oven: 15 to 17 years. Burners and igniters are cheap repairs along the way.
- Microwave (over-range): 8 to 10 years.
- Garbage disposal: 8 to 12 years.
The Three Replace Signals
A part failing doesn’t mean the appliance is done. Use these three rules together:
- Cost. The repair quote is more than 50 percent of a comparable new unit. A $400 control board on a $700 dishwasher is a replace.
- Age. The unit is past its average lifespan: roughly 10 years on a mainstream brand, 15 on a luxury brand.
- Failure count. It’s the second major component failure inside 12 months. Compressors, control boards, and motors count; gaskets and filters don’t.
If two of the three line up, replacement is the smarter spend. If only one does, repair almost always wins. We walk this same math with you on every diagnostic, and we put the verdict in writing. For the deeper version, see our repair or replace guide.
Dishwasher: The Most Misread Unit
The dishwasher gets replaced too early more than any other appliance, usually because of three fixable problems mistaken for death.
- Not draining or standing water. Almost always a clogged filter, drain hose kink, or failed drain pump. Cheap fixes, not replace signals.
- Dishes coming out gritty. Scaled spray arms or a tired wash pump. In hard Tri-Valley water this is a maintenance issue, not a worn-out machine.
- Won’t start or stops mid-cycle. Door latch switch or control board. The latch is a low-cost part; the board is where the cost rule kicks in.
A genuine replace signal on a dishwasher is a cracked tub or a leaking sump that’s soaked the floor more than once, on a unit already past 10 years. Walk through the rest in our dishwasher repair guide.
Refrigerator, Washer, Dryer
Refrigerator: the icemaker and water dispenser fail first, often around year 8. Those are repairs. The real end comes from a sealed-system leak on an older mainstream unit, where the cost rule usually says replace. On a built-in luxury fridge, the same rebuild is worth doing.
Washer: a front-loader that howls during spin has a worn drum bearing. On a unit past 10 years, the bearing job often crosses the 50 percent line. Replace. Under 10 years, repair it.
Dryer: no heat is usually a thermal fuse, heating element, or gas igniter, all reasonable repairs at any age. The dryer earns a replace verdict only when the drum or cabinet itself fails, which is rare.
Get Extra Years Out of Each One
Maintenance moves every number on this page upward:
- Clean the dishwasher filter monthly and run a descale cycle in hard water.
- Vacuum refrigerator condenser coils twice a year.
- Empty the dryer lint trap every load; clean the full vent line yearly.
- Don’t overload the washer, and leave the door cracked open between loads.
When to Call a Pro
Call when you hit a major component (compressor, control board, motor, sealed system), when an appliance is leaking onto the floor, or when you simply want the repair-or-replace math run before you spend money on a unit that’s near the end. We charge a flat $75 diagnostic, credited to the repair, and you get a written estimate and a clear verdict before any wrench work.
