Michael Thompson Key Takeaways
- The published ten-to-thirteen-year average covers machines used and installed very differently, so it decides nothing about yours.
- LG dryers measure their own exhaust restriction: a d80 or d90 code names the duct, not a fault in the appliance.
- A dryer working against a restricted duct ages faster in every respect — element, fuse, motor, and blower all work harder.
- Belts, rollers, idlers, elements, thermostats, and sensors are all inexpensive; the motor and the drum bearing are not.
- A cracked drum or a rusted cabinet ends the decision at any age, because neither is an economic repair.
The Bottom Line
Clear the duct before drawing any conclusion about the appliance — on a dryer that single step removes the reason for a great many service calls. Past that, repair everything except a cracked drum, a rusted cabinet, or a motor on a machine already past twelve years.
People ask how long do LG dryers last while standing in front of one that has just done something worrying, and the number they find — usually ten to thirteen years — describes an average across machines that are used and installed very differently. What actually decides the life of yours is not the model. It is airflow, and specifically whether the duct behind it has ever been cleared. A dryer that has spent ten years venting into a partly blocked run has been working harder than the calendar suggests for most of that time.
| Stage | What typically fails | What it means |
|---|---|---|
| Years 1–4 | Door switch, thermistor, control quirks | Warranty-age faults, cheap |
| Years 4–8 | Drum rollers, idler pulley, belt | Wear items, inexpensive |
| Years 8–12 | Heating element, thermal fuse, blower | Ordinary repairs, often vent-related |
| Years 12+ | Motor, drum bearing, cabinet | The decision point |
| Any age | Cracked drum, rust through | Ends it regardless |
| Any age | Duct blockage codes | Not the dryer — the duct |
The Duct Is the Life Expectancy
LG dryers report on this directly, which is unusually helpful. A d80 code means the machine has measured its exhaust restriction at around eighty percent, and d90 at around ninety. Those are not faults in the dryer. They are the appliance telling you that the duct behind it is nearly closed and that everything it does from now on will take longer and run hotter.
A dryer working against that restriction ages faster in every respect: the element cycles more, the thermal fuse sits closer to its limit, the motor runs longer for each load, and the blower works against back-pressure. An owner who clears the duct on a schedule is not being fussy — they are buying years.
Three Things That Take Years Off
- A duct nobody clears. Covered above, and it is the biggest factor by a distance.
- Overloading. A drum packed past its rating puts the belt, the rollers, and the bearing under load they were not designed for, every single cycle.
- Installation. A dryer that is not level, or one in a closet with no make-up air, works harder than the same machine in a well-arranged laundry room.
And one thing that does not: number of years in the house. A lightly used dryer in a two-person household is barely worn at ten years. A family machine running fourteen loads a week is not comparable.
Use Matters More Than Years
A dryer wears by loads, not by calendar. A two-person household running three loads a week puts roughly a fifth of the work through a machine that a family of five running fourteen loads a week does, and at the ten-year mark those two dryers are not comparable appliances however identical they looked on the delivery truck.
That is worth holding on to when reading any lifespan figure, including the one at the top of this page. A lightly used dryer at twelve years may have years left; a heavily used one at eight may be close to the end of its drive components. The honest measure is what the machine is doing now, not how long it has been in the house.
What Decides Repair at Any Age
- Is the drum sound? A cracked drum snags and tears clothing, and it is not an economic repair. This ends it whatever the age.
- Is the cabinet rusted through? Same answer.
- Is it the motor or the bearing? These are the two genuinely expensive parts, and past twelve years they are where the arithmetic turns.
- Is it stacked or closet-fitted? If replacing means matching a specific footprint and door swing, the repair ceiling rises the way it does for built-in kitchen appliances.
Everything else — belts, rollers, idlers, elements, thermostats, thermal fuses, sensors — is inexpensive, and our dryer repair or replace guide puts those numbers side by side.
Gas and Electric Age Differently
An electric dryer heats with a resistive element, which is a consumable in the same way a light bulb is: it works until it does not, and replacing it is straightforward and inexpensive. A gas dryer heats with an igniter, a flame sensor, and valve coils, and those wear differently — the igniter in particular is a known wear item that is expected to be replaced once or twice over the machine's life.
Neither is expensive, and neither says anything about the rest of the appliance. What it does mean is that "no heat" is more self-explanatory on an electric machine and worth describing carefully on a gas one. Our guide on an LG dryer not heating covers both.
Signs a Dryer Is Genuinely Near the End
Three things suggest wear rather than a fault:
- A rumble that has been getting louder for a year. Rollers and the idler first, drum bearing eventually.
- Cycles that have grown steadily longer on a duct you know is clear.
- A drum that has developed a rough spot you can feel with a hand, or that has started marking clothes.
The first is a repair, the second is worth measuring properly, and the third is the one that ends it.
Getting a Real Answer
Diagnostic visits start from $89, with the final price confirmed after the on-site diagnosis and a written estimate before any work begins. Clear the duct before booking — on this appliance more than any other, that single step frequently removes the reason for the call.
Our LG dryer repair service covers the heating circuit, the drive components, and the sensing. If the machine smells of burning or the cabinet runs hot, stop using it and book a visit — that combination is not about age at all.
