The short answer
A dryer that stops part-way through, or declares itself finished with the load still wet, is usually protecting itself or being misled about the load. On a compact cabinet the air path and the moisture sensor come first in the ranking, because a restricted duct trips the thermal protection and a dirty sensor ends a cycle early. Both are owner checks and neither costs anything.
What you observe
- The cycle ends early with the load still wet — The moisture sensor calling the load dry when it is not.
- It runs the full time and stops with wet clothes — That is a heating or airflow complaint rather than a cycle fault.
- It stops the moment the door is nudged — A door switch that is marginal rather than a cycle problem.
- NEAR MISS: it beeps and stops with the drum full of cold air after a power cut — Some machines abandon a cycle after an interruption.
Causes, most likely first on this appliance
- A sealed lint screen — Fabric-softener film seals the mesh without looking blocked, which restricts airflow and produces the same thermal cut-out as a blocked duct. Ranked first on Danby: a compact dryer moves far less air and carries far less mass than a full-size one, so a restriction or a looseness a big machine would absorb stops a small one outright, and this line spans bar cabinets to apartment units, all of them designed to go where a full-size appliance would not.
- A marginal door switch — The switch that proves the door shut. Ranked second: it is in the middle of the list because it is cheap to rule out and expensive to assume.
- A restricted vent duct — Heat that cannot escape raises the cabinet temperature until a limit opens and stops the machine. Ranked third: it ranks below the causes above because it costs more effort, not because it is rare.
- The control board or the timer — What is left once airflow, sensing and the door are clean. Ranked last: it is last because on an appliance this size the major components outlive everything around them, and replacing one often costs more than the appliance is worth.
Check in this order, and why
- Pour water through the screen — Water that beads rather than running through means the screen is sealed and needs washing.
- Note whether it stops when the machine is nudged — A stop that follows a knock rather than a time points at the switch and that is service work.
- Feel the airflow at the outside hood while it runs — Weak air at the hood with the machine running is conclusive, and this check takes a minute.
What an owner can safely check
- Wash the lint screen with hot water, detergent and a brush — Scrub both faces, rinse until water runs straight through, dry it and refit it before running the machine.
Tools: soft brush, detergentAbout 15 min
- Clear the duct end to end and check the outside hood — With the machine unplugged, pull the duct, brush it clear, confirm the hood flap swings freely and refit with clamps.
Tools: vent brush, screwdriverAbout 60 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the machine or switch off its breaker before pulling the duct, opening the lint housing or reaching inside the cabinet, and keep it off while your hands are inside. On a gas dryer, shut the gas valve at the machine before disturbing anything, and if you smell gas at any point: do not switch anything on or off, leave the building, and call the gas utility or your emergency services number from outside. Do not look for the leak yourself.
When to call a technician
Call once the lint screen, the duct, the outside hood, the sensor bars and a normal load have all been addressed and the machine still stops. What is left is a thermal device, a door switch or the control, and a thermal device that has opened must be replaced alongside clearing whatever blocked the air path.
