The short answer
A cycle that ends at the wrong time on an AGD dryer usually comes down to the moisture sensor rather than the timer: a film of softener on the sensor bars tells the control the load is dry the moment the cycle starts. The order that follows puts the likeliest and cheapest causes first, and it is the order worth working in rather than starting with the part that sounds most serious.
What you actually observe
- The cycle runs far longer than it used to for the same load — Air is not moving, so moisture is not leaving.
- The machine gets hot but the laundry stays damp — Heat without airflow, which is the signature of a restricted duct.
- The cycle ends after a few minutes with the load still wet — An automatic cycle being told the load is already dry.
- It will not start a cycle at all — NEAR MISS: read the will-not-start page for this machine.
- Body: The AGD listings carry a masked suffix in the spine, so the trailing characters on your rating plate will differ from the table without changing the diagnosis.
What causes it on the AGD platform, in likelihood order
- 1. The metal strips inside the drum — An automatic cycle measures conductivity between two metal bars in the drum. The control ranks this high on AGD because a single listing means a single control variant, so it is either the fault or it is not.
- 2. The lint screen and its housing — Rinse the screen under a tap: water that beads and sits on the mesh rather than running through is the whole diagnosis. Second on AGD because the duct is the root cause behind much of the class above it, and clearing it is what stops a repeat.
- 3. The vent run behind the machine — Lint collects along the duct and at the outside hood, and once airflow falls the machine cannot carry moisture away.
- 4. The thermistor or cycling thermostat — It ranks below the airflow causes because a restricted vent produces exactly the same readings from perfectly good parts.
The order to work in on this platform
- 1. Compare an automatic cycle against a timed cycle with the same load — The cleanest single test on this appliance, and it needs no tools.
- 2. Rinse the screen under a tap and watch whether water passes through — Beading water on a screen that looks clean is an invisible restriction.
- 3. Disconnect the duct and run a short cycle exhausting into the room — If the behaviour changes, the duct is the fault and nothing inside the machine is.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before any panel comes off; a capacitor can hold a charge after the power is off, and a large appliance circuit is typically 30 A or higher at 240 V. Never run the machine with its exhaust duct disconnected for longer than a short test, and never use a plastic or foil concertina duct as a permanent repair. Where a step below depends on which AGD listing you own, the table above is the reference; nothing here is written from a model outside it.

When to call a technician
The line is the cabinet. Ducts, hoods, lint screens and cycle choice are all owner work; a sensor circuit, a thermistor or a control board means panels off and a meter on live terminals.
