Every appliance repair call ends with a version of the same question: “Is this worth fixing?” It’s a fair question, nobody wants to sink money into a 14-year-old dryer only to have the motor die six months later.

Here’s the honest math, broken down by appliance. This is the same math we run with customers before quoting a repair, if replacement wins, we’ll tell you.

The 50% rule (and where it fails)

The classic rule of thumb: if the repair costs more than 50% of a replacement, replace.

It’s a decent starting point. It fails for two reasons:

  1. It ignores remaining useful life. A repair on a 2-year-old fridge and the same-priced repair on a 12-year-old fridge are different economic decisions even if the replacement cost is identical.
  2. It ignores quality differences. A compressor swap on a high-end built-in like a Sub-Zero is almost always worth it relative to what the appliance is worth. The same repair on a basic-grade fridge usually isn’t, because the repair eats up a much bigger share of the unit’s value.

Better rule: repair if (repair cost + expected remaining life value) > replacement cost. Harder to calculate, but more honest.

Refrigerators

Typical lifespan: 10-15 years (20+ for Sub-Zero, Thermador, Viking, Miele)

Usually worth repairing:

  • Under 10 years old: most common repairs are worth it
  • Ice maker, water valve, door gasket: at any age
  • High-end built-in brands: almost any repair at any age
  • Compressor on a unit under 6 years old: yes, under warranty if applicable

Usually worth replacing:

  • Over 12 years old with a sealed-system failure (compressor, evaporator leak)
  • Any unit over 15 years old with a major repair
  • Basic-grade units where the repair cost runs high relative to a new unit

San Diego note: coastal homes see condenser corrosion in 8+ years, factor in a shorter expected remaining life on coastal fridges.

Washing machines

Typical lifespan: 10-13 years

Usually worth repairing:

  • Under 8 years old: most common repairs are worth it
  • Drain pump, door gasket, drive belt, shocks: at almost any age
  • Front-loader bearings on a unit under 6 years old: yes, it’s a real repair bill but still cheaper than replacement
  • High-end brands (Miele, Speed Queen): repair at any realistic cost

Usually worth replacing:

  • Over 10 years old with a bearing failure or control board failure
  • Any unit with multiple concurrent failures (“and also the seal is leaking and also the motor is making noise”)
  • Top-loaders from the low-efficiency era (pre-2012) are often ready to retire on their first major failure

Dryers

Typical lifespan: 13-18 years (simplest major appliance, fewest parts to fail)

Usually worth repairing:

  • At almost any age, almost any common repair
  • Heating element, thermal fuse, belt, idler pulley, thermostat: all inexpensive fixes
  • Motor replacement: yes on units under 12 years old

Usually worth replacing:

  • Drum bearings on a 15+ year-old dryer where labor is the majority of the cost
  • A unit where the control board has failed AND another major component is also borderline

Dryers are the best value in appliance repair, long life, cheap parts, simple mechanics. Usually worth repairing.

Dishwashers

Typical lifespan: 8-12 years (10-18 for Bosch, Miele, high-end)

Usually worth repairing:

  • Under 7 years old: most common repairs are worth it
  • Drain pump, door gasket, filter, circulation motor: at most ages
  • High-end brands (Bosch, Miele, KitchenAid): repair at most ages
  • Any dishwasher still in warranty

Usually worth replacing:

  • Over 10 years old with any major failure on a builder-grade unit
  • Any dishwasher where the tub has cracked (very rare but unrepairable)
  • Units where the repair requires the control board AND the circulation motor, total cost usually exceeds replacement

Ovens, ranges, and cooktops

Typical lifespan: 15-20 years (longer than any other kitchen appliance)

Usually worth repairing:

  • At almost any age for any common repair
  • Igniter, bake element, door hinge, burner switch: inexpensive in most cases
  • High-end brands (Wolf, Viking, Thermador, La Cornue, Miele): repair at any realistic cost
  • Induction cooktops: control board replacements usually pencil

Usually worth replacing:

  • Gas range with a cracked main gas valve AND an old cooktop (safety + age combined)
  • Built-in wall oven over 18 years old where the cavity has heat damage
  • Any range where the structural cabinet is rusted or warped

Range/oven is the longest-lasting major appliance. Almost always worth repairing.

Microwaves

Typical lifespan: 8-10 years (countertop); 10-14 years (built-in and OTR)

Usually worth repairing:

  • Built-in trim-kit units ($900+ retail): almost any repair is worth it
  • Over-the-range microwaves under 7 years old: door switches, magnetrons, turntable motors
  • High-end brands (Wolf, Miele): at most ages

Usually worth replacing:

  • Countertop units under $200 retail: always replace (labor alone exceeds replacement)
  • Over-the-range units over 10 years old with magnetron failure

Garbage disposals

Typical lifespan: 8-12 years (longer with heavier-duty Pro series)

Usually worth repairing:

  • Jams, tripped reset, switch issues: at any age
  • Under 6 years old: most component repairs

Usually worth replacing:

  • Housing leaks (the body is cracked, no repair possible)
  • Over 8 years old with any major failure
  • Any disposal where the motor has seized

Replacement cost varies with the unit’s horsepower and features, but on an older disposal it’s often less than the combined cost of a diagnostic plus repair, especially once the housing has cracked or the motor has seized.

The three questions to ask yourself

Before approving any repair, ask:

  1. How old is the appliance? Past the typical lifespan, expect more failures even after this repair.
  2. Is this a first failure or a pattern? Three small failures in 18 months means something systemic is wearing out.
  3. Does the repair cost exceed 50% of the replacement, and is the unit less than 75% through its expected life? If both are “yes,” replace.

When we tell customers to replace

The techs in our network are trained to be honest about this. If the math says replace, we tell you. We’d rather lose a repair today than have you feel ripped off when the next component fails six months later.

We also keep ourselves out of the selling-new-appliances business on purpose. That removes the incentive to push replacement when repair is right.

Get an honest diagnostic

Ask the technician about their diagnostic fee and whether it’s credited toward the repair. They’ll tell you what’s actually wrong, quote the fix, and give you an honest read on whether this is worth doing. Fridges are one of the most common appliances we’re asked about, so our refrigerator repair page has more detail on what typical repairs cost and what to expect.

Frequently asked questions

What is the 50% rule for appliance repair?

If the repair costs more than 50% of what a comparable new appliance costs, replacement is usually the smarter financial move. The rule has limits though: the same-priced repair on a 2-year-old fridge is a very different bet than on a 12-year-old fridge, even if the replacement price is identical.

Which appliance is almost always worth repairing?

Dryers and ranges have the longest useful lives and the cheapest parts. A dryer heating element, thermal fuse, belt, or thermostat is an inexpensive repair and the appliances routinely last 13 to 18 years. Ovens and ranges last 15 to 20 years, and common repairs like an igniter or bake element cost well under the 50% threshold at most ages.

When should I replace a washer instead of repairing it?

Replace if the unit is over 10 years old and needs a bearing replacement or a control board. Also replace if there are multiple concurrent failures, for example a worn seal plus a noisy motor on the same machine. Multiple small failures in 18 months usually signal something systemic wearing out, not just bad luck.

Does the diagnostic fee get credited toward the repair?

Ask the technician about their diagnostic fee and whether it’s credited toward the repair if you move forward. The technicians in our network quote the repair before starting, so you know the full cost before approving any work.
