The four-question framework
Skip the internet arguments. Four questions settle almost every repair-or-replace decision, and you need a real diagnosis before you can answer the first one honestly.
1. What actually failed — and what will that repair cost?
Not the symptom, the failure. "Not cooling" isn't a diagnosis. A firm quote for a confirmed failure is the only number worth putting into this equation. Our St. George appliance repair cost guide explains what drives that number.
2. How old is the appliance relative to its expected life?
An appliance in the first half of its expected lifespan is usually worth repairing. Past about 75% of expected life, the calculation tightens fast, because the components you aren't replacing today are aging too.
3. Does the repair cost more than roughly half of a comparable new unit?
This is the classic 50% rule, and it's a decent guardrail. Under half, repair usually wins. Well over half on an older appliance, replacement usually wins. In between, question four decides it.
4. What is the true replacement cost — all-in?
Not the sticker price. Delivery, installation, haul-away, possible cabinetry or panel work, electrical or plumbing changes, and the weeks you may wait for a built-in unit to arrive. People routinely underestimate this by thousands on integrated appliances.
The rule of thumb, stated plainly
Expected appliance lifespans
| Appliance | Typical lifespan | Usually repair if under |
|---|---|---|
| Refrigerator | 10–15 years | 10 years |
| Standalone freezer | 12–16 years | 11 years |
| Dishwasher | 9–12 years | 8 years |
| Washing machine | 10–13 years | 9 years |
| Dryer | 10–14 years | 10 years |
| Gas range / oven | 15–17 years | 13 years |
| Electric range / oven | 13–15 years | 11 years |
| Microwave | 7–10 years | 6 years |
| Ice maker | 8–12 years | 8 years |
| Wine & beverage cooler | 10–14 years | 10 years |
| Vent hood | 12–20 years | 15 years |
| Built-in luxury units | 20+ years | 18 years |
Treat these as averages, not promises. A well-maintained machine routinely outlives the range; a neglected one in a hot Southern Utah garage routinely falls short of it.
Signs the appliance is worth repairing
- It's in the first half to two-thirds of its expected lifespan
- This is the first significant failure it has had
- The failed part is a common, well-supported component
- The cabinet, tub, drum, and door seals are structurally sound
- It's a built-in, integrated, or luxury unit
- The repair is well under half the all-in cost of replacing
- You like how it performs and it fits your space and panels
- Parts are readily available for the model
Signs it's time to replace
- Repeated failures. Two or more unrelated repairs in the last 12 months is a pattern, not bad luck.
- Compressor or sealed-system failure on a mass-market refrigerator or freezer past about 10 years.
- Structural damage. Cracked tub or drum, rusted-through cabinet, warped door, damaged frame.
- Parts no longer made. When a control board is discontinued, the appliance's clock has run out.
- Safety issues. Gas smell, scorched wiring, burning odor from the control panel, or a unit that trips breakers repeatedly.
- Repair quote near or above half of new on an appliance already past three-quarters of its expected life.
- A very old, always-on unit. A 20-year-old garage refrigerator draws power around the clock; replacing it is often the right call on running costs alone.
A closer look, appliance by appliance
Refrigerators and freezers
Repair confidently for defrost systems, thermistors, fan motors, door gaskets, water valves, and control issues on units under about 10 years. Lean toward replacement when a compressor or sealed system fails on an older mass-market unit — that's the single most expensive repair on a refrigerator, and the rest of the machine is the same age.
Dishwashers
Pumps, valves, latches, spray arms, and racks are typically worth fixing. Persistent leaks from a cracked tub, or a control failure on a unit past about 10 years, usually point to replacement. In our hard water, a dishwasher that's never been descaled ages faster than the calendar suggests.
Washers and dryers
Dryers are the most repair-friendly appliance in the house — elements, thermal fuses, belts, rollers, and thermostats are straightforward, and many dryers reach 15 years. Front-load washer bearing failures are the main replace-leaning case, since the labor is significant. Before you blame the dryer at all, rule out a restricted vent with dryer vent cleaning — it causes more "broken dryer" calls than any actual part.
Ovens, ranges, and cooktops
Elements, igniters, sensors, thermostats, and knobs are usually simple, sensible repairs. Ranges last a long time, so the age threshold is more forgiving. Replacement is typically driven by control board failures on older units or by a remodel.
Microwaves
Countertop microwaves are usually not economical to repair. Over-the-range and built-in microwaves are a different story — the unit and the install both cost real money, so a repair is often worth it.
Built-in and luxury appliances are a different calculation
The 50% rule breaks down on high-end equipment. A Sub-Zero column, Wolf range, Viking built-in, or GE Monogram suite is designed for two decades or more of service and is meant to be maintained, not discarded. Replacement often means matching custom panels, modifying cabinetry, and waiting weeks or months for delivery.
For these appliances the right question usually isn't "repair or replace" — it's "who is authorized to do this repair correctly."
What Southern Utah changes about the math
- Hard water shortens the life of dishwashers, washers, and ice makers unless they're descaled and filtered on schedule.
- Extreme heat is brutal on refrigeration. A garage fridge in St. George lives a much harder life than the same model in a conditioned kitchen — see the desert heat guide.
- Rentals and second homes should lean toward replacing marginal appliances. A failure while guests are in the house costs far more than the appliance. The rental prep checklist covers the rest.
- Delivery and installation timelines for built-ins can run long here. Repairing to buy planning time is often the smart move.
The hidden costs of replacing
- Delivery, installation, and haul-away of the old unit
- Cabinetry, trim, or panel modification for a unit with different dimensions
- New water line, gas line, or electrical work to meet the new appliance's requirements
- Days or weeks without the appliance while you wait for delivery
- A new learning curve, and a new set of first-year quirks
- Losing a well-built older machine for a newer one with more electronics
Not sure which side of the line your appliance falls on? Get it diagnosed first — then compare a real number against a real all-in replacement cost. Keep the appliances you do have running longer with the Southern Utah appliance maintenance calendar.
Frequently asked questions
What is the 50% rule for appliance repair?
The common rule of thumb says that if a repair costs more than about half the price of a comparable new appliance, replacement is usually the better value. It's a starting point, not a law — an appliance's age, remaining lifespan, and how well it has been maintained matter just as much.
How long should appliances last?
Rough averages: refrigerators 10–15 years, freezers 12–16, dishwashers 9–12, washers 10–13, dryers 10–14, gas ranges 15–17, electric ranges 13–15, microwaves 7–10, and built-in luxury units often 20+ years with proper service. Southern Utah heat and hard water tend to pull the low end lower.
Is it worth repairing a 10-year-old refrigerator?
Often yes, if the failure is a common, well-understood component like a defrost system, thermistor, fan motor, or door gasket, and the rest of the unit is in good shape. It's usually not worth it if the compressor or sealed system has failed on a mass-market unit that age.
Should I repair a luxury built-in appliance or replace it?
Almost always repair. Sub-Zero, Wolf, Viking, Thermador, and GE Monogram units are engineered for two decades or more of service, replacement means matching cabinetry and panels, and installation costs alone can dwarf the repair. Even significant repairs typically make financial sense on these.
Does an appliance being out of warranty mean I should replace it?
No. Out-of-warranty simply means you pay for the repair. Plenty of appliances have most of their service life remaining the day the warranty ends. Judge by the failure, the age, and the condition — not the warranty date.
Will a new appliance really save me money on energy?
It can, especially replacing a refrigerator or freezer older than about 15 years, since those run continuously. For a dryer, dishwasher, or oven that only runs a few hours a week, energy savings rarely justify replacement on their own.
What are the clearest signs an appliance should be replaced?
Repeated failures within a year, a failed compressor or sealed system on an older unit, cracked tubs or drums, major rust or structural damage, unavailable parts, safety issues like gas leaks or scorched wiring, and repair quotes approaching half the cost of new.
Do appliances last as long in Southern Utah?
Often a bit less. Very hard water scales dishwashers, washers, ice makers, and water lines, and extreme summer heat is hard on refrigeration — especially in garages. Consistent maintenance closes most of that gap.
How do I get an honest answer about whether to repair?
Have a technician diagnose the actual failure first, then compare the firm repair quote against the replacement cost including delivery, installation, and haul-away. A trustworthy shop will tell you when replacing is the better call — we do.
