The short answer
This page covers a vented Fisher & Paykel dryer that runs but will not dry. On a vented machine the exhaust duct is the first suspect, not the heater: restricted air carries no moisture away, so the drum feels warm, the clothes stay damp, and the machine looks exactly as though the element has failed. The condensing and heat-pump models behave differently and the companion page covers them.
Causes, ranked for this Fisher Paykel dryer
- Exhaust duct restricted or too long — Why: Every metre of duct and every bend costs airflow, and a duct that has silted or been crushed behind the machine strangles drying without touching the heat source at all.
- Lint screen or its housing blocked — Why: A screen that looks clean can be sealed by fabric-softener film, and lint that has passed it settles in the housing where nobody looks.
- External vent flap stuck shut — Why: A wall flap seized by paint, ice or a nest blocks the exhaust completely while everything visible in the laundry room appears perfect.
- Heating element or thermal cut-out failed — Why: A genuinely cold drum belongs here, but a restricted duct trips the cut-out first, so airflow must be ruled out before anyone condemns a part.
- Overloading or wet-in loads — Why: A drum packed tight cannot tumble, and clothes that leave the washer soaked take far longer, which is often reported as a heating fault.
What to check, in order
- decide whether the drum is warm or cold. — Because: warm-but-damp is an airflow diagnosis and cold is a heat diagnosis, and they share nothing else.
- clean the lint screen and look into its housing with a torch. — Because: it is free, it is the commonest restriction, and film on a screen is invisible when dry.
- disconnect the duct and run the machine briefly on a heat setting. — Because: strong hot exhaust straight from the machine proves the fault is in the duct beyond it.
- go outside and watch the vent flap while the dryer runs. — Because: a flap that never opens is a total blockage that is invisible from indoors.
Checks you can safely do yourself
- Run a short heated cycle and put your hand in the drum at the end to establish whether it is warm or cold. — Tools: none — Time: several minutes
- Remove the lint screen, wash it in warm soapy water to strip softener film, dry it and vacuum the housing beneath. — Tools: a vacuum and warm soapy water — Time: several minutes
- Switch off at the breaker, pull the machine forward and check the duct behind it for crushing or a collapsed section. — Tools: a torch — Time: several minutes
- Disconnect the duct from the machine, brush it through its full length, and clear the wall flap outside. — Tools: a vent brush and a vacuum — Time: the better part of an hour
- Reconnect, run a small load and compare the time taken. Stop here: the element and thermal cut-outs need metering inside the cabinet. — Tools: none — Time: the better part of an hour, mostly waiting
Before you open anything
Safety
unplug-before-service branch-circuit-15-20a
Lint is combustible and a restricted vent is the mechanism behind most dryer fires, so treat repeated cut-outs as urgent rather than annoying. Kill power at the breaker before moving the machine or opening any panel, and never fit a plastic or foil concertina duct in place of a rigid or semi-rigid one.
Where the owner fix ends
Cleaning the screen, clearing the duct and freeing the wall flap are owner work. Call a technician when the duct is clear, the flap opens and the drum is still cold, because the element and thermal cut-outs must be metered inside the cabinet; and when the machine repeatedly cuts out on temperature with a confirmed clear vent.
