The short answer
On Fisher & Paykel a cycle that ends early or stalls is most often a lint filter and housing restricting the airflow, not a failed control board. Ranked that way because the drum runs on a direct-drive layout with far fewer wear parts in the path than a belt-and-idler machine has.
What you observe
- The cycle ends after a few minutes with a damp load — The classic moisture-sensor signature, and the cheapest thing on the list to fix.
- Towels are damp but shirts in the same load are dry — A loading answer rather than a fault. The sensor measured the driest items.
- NEAR MISS: it tumbles the whole cycle with no heat at all — That is a heating fault rather than a cycle fault, and it has its own page.
Causes, most likely first on Fisher & Paykel
- The lint filter and its housing are restricting airflow — First here, where a modulating control hides a developing fault rather than announcing it. A machine that cannot move air runs its thermal protection, cuts the heat and cycles off early. It is the most common restriction and the one with a fire risk attached, which is why it is never skipped.
- The moisture sensor is reading through a residue film — Second, and the cause this control is least able to tell you about. The metal strips inside the drum measure how wet the clothes are by conductivity, and a film of fabric softener insulates them. The machine reads dry clothes, ends the cycle and leaves a damp load, which is exactly this fault.
- The load is too large, too wet or too mixed — Third. A sensing cycle measures the driest items it touches.
- The thermistor, the control board or a thermal cut-out has failed — Last, and it is the reason the order above matters. It stops at the same point with a clean sensor, a clear filter, a clear vent and an appropriate programme.
Check in this order, and why
- Pour water through the filter and watch whether it passes — Water that beads on the mesh names a blockage you cannot see, and it is free to check.
- Find the metal sensor strips inside the drum and look at them — A dull or filmed strip is a confirmed cause, and wiping it is a five-minute fix.
- Note whether the damp items are the heaviest things in the load — Damp towels beside dry shirts is a loading answer, not a machine fault.
What an owner can safely check
- Wash the lint filter, dry it fully, and vacuum the housing below it — Refit it dry: a wet filter restricts airflow just as badly as a blocked one.
Tools: vacuum, warm soapy waterAbout 20 min
- Wipe the sensor strips inside the drum with a cloth and rubbing alcohol — Do this whenever a cycle starts ending early; residue builds gradually.
Tools: cloth, rubbing alcoholAbout 10 min
- Dry heavy and light items separately, and re-spin anything that went in dripping — Use a timed programme for a mixed load rather than a sensing one.
About 20 min
- STOP HERE if the next step needs a meter on live terminals — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before removing any panel or reaching into the lint housing. A restricted vent is a fire risk and not a performance complaint: stop using the machine if the cabinet feels hot or you smell scorching. If you smell gas at a gas dryer, do not switch anything on or off, leave the building and call the gas utility or the emergency services from outside.
When to call a technician
Call when the sensor is clean, the filter and vent are clear, the programme is right and the machine still stops at the same point, because that puts the fault in a thermistor, a thermal cut-out or the control. Call immediately if the cabinet is hot, if you smell scorching, or if a gas machine smells of gas.

What this page does not cover
This page covers the brand and the dryer class, not one family or model line. Where a family-specific or model-specific page exists for your unit, that page is the more specific answer and it takes precedence over this one. Not here: part numbers, wiring colours and component locations, which differ by family.
