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 an imported mass-market 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 machine stops part-way and restarts only after it cools — Thermal protection operating, which points at airflow.
- 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.
- 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 restricted vent duct — Heat that cannot escape raises the cabinet temperature until a limit opens and stops the machine. Ranked first on Daewoo: these machines are commonly fitted to a vent run that was already there and was never sized for them, so the installation beats the appliance to the top of the list, and on an apartment-size platform built to a price the seal and the door take the heaviest share of the faults.
- A marginal door switch — The switch that proves the door shut. Ranked second: it sits here because it mimics the cause above it closely enough that checking in the wrong order wastes a visit.
- 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 third: it is placed here because it is the first cause that needs more than a look.
- A thermal fuse or cycling thermostat at the end of its life — These open on heat, and once they have been stressed by a blocked duct they open earlier each time. Ranked last: it is last because it is genuinely uncommon on this platform, and because it is the one cause an owner cannot confirm or fix without licensed tools.
Check in this order, and why
- 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.
- 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.
- Pour water through the screen — Water that beads rather than running through means the screen is sealed and needs washing.
What an owner can safely check
- 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
- 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
- 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.
