# Why the Dryer Says an Hour and Then Suddenly Says One Minute

## How to fix LG dryer not drying: which version do you have?

Two very different complaints share this sentence, and separating them takes one cycle.

**The cycle ends early and the clothes are wet.** The machine believes it has finished. That is sensing.

**The cycle runs long, the machine gets hot, and the clothes are still damp.** The machine is trying and failing. That is airflow.

Everything below is about the first. If you have the second, the duct is where to look, and LG measures its own restriction and prints it on the display as d80, d90 or d95 — which is more help than most makes give.

## The number was never a countdown

On a sensor-dry cycle, the time on the display is a running estimate.

When you press start, the machine knows three things: which program you chose, roughly how much is in the drum from the load, and how wet it is at that instant. From those it produces a number, because an appliance showing nothing at all would be worse. Then it keeps measuring, and the number gets revised.

When the load reaches the dryness the program was set for, there is nothing left to estimate. What remains is the cool-down — a few minutes of tumbling without heat so nothing comes out hot enough to crease — and the display shows that. Fifty-nine minutes vanish because they were never real.

## How the sensing works, and what breaks it

Inside the drum opening there are two thin metal strips, usually on the front bulkhead near the lint screen slot, an inch or two apart. They are not a temperature sensor and not a humidity sensor. They are two electrical contacts.

A wet garment tumbling past touches both at once and completes a circuit, because water conducts and dry fabric does not. The machine counts how often that happens. Early in a cycle it happens constantly; as the load dries the contacts become rarer, and below a threshold the machine decides the load has reached the dryness you asked for.

It is elegant because it is simple — no calibration, no consumables, nothing to drift. Which is why the one thing that defeats it is worth knowing.

## The film nobody can see

Liquid fabric softener and dryer sheets both leave residue. On the lint screen it shows as the waxy film that makes a clean-looking screen pass no air. On the sensor strips it does something worse: it **insulates** them.

A thin coating means wet fabric no longer completes the circuit reliably. The machine stops seeing contact, concludes the load is dry, and collapses the estimate — sometimes within five minutes of starting, on clothes that are soaking.

That is the version that is a real symptom, and the tell is timing. A jump near the **end** of a cycle with dry clothes is the machine working correctly. A jump near the **beginning** with wet clothes is the sensor being wrong.

The fix is usually free: rubbing alcohol on a cotton pad, wiped along both strips until they are bright metal again. One minute. If the next load behaves, that was the repair and everything else you were about to do was unnecessary.

## The test that settles it

Run a **timed** cycle rather than an automatic one. Timed cycles do count down, and they always did — they run the drum and the heat for a fixed period regardless of what any sensor thinks.

If a timed cycle dries the load properly and an automatic one does not, that is the sensor and nothing else. If a timed cycle also leaves things damp, the problem is heat or air, and you are on a different page.

## What LG calls it

**HS** is the code when the humidity sensing fails outright. Far more common is the version with no code at all — a sensor that has not failed, merely drifted behind a film — which is why this behavior gets reported as a mystery rather than looked up.
