The short answer
A dryer that will not start is usually being stopped by the door, the supply or a control state rather than by a failed part. On an imported mass-market cabinet those three lead the ranking because they cost nothing to check and because between them they explain most of these calls. What is left after them is behind the cabinet and is service work.
What you observe
- It starts and stops within a second — A door switch making and breaking as the door flexes.
- It only runs while the start button is held — A motor start circuit that is not latching, which is a known service pattern.
- Nothing happens at all when start is pressed — Supply, door or control lock rather than a mechanical failure.
- NEAR MISS: it runs and tumbles but leaves clothes wet — That is a heating or airflow complaint and belongs on a different page.
Causes, most likely first on this appliance
- No power, or only half of it — An electric dryer takes both legs of a large-appliance circuit. 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.
- The door is not latching — The door switch proves the door shut before the motor will run. Ranked second: it ranks here because it is common on this platform but slower to develop than the cause above.
- A control lock or a delay start — A child lock engaged by a long press, or a delay timer set by mistake. Ranked third: it ranks here because on this platform it is the second thing to go, not the first.
- A failed door switch — The switch itself rather than the latch. 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
- Check the breaker and reset it fully — A large-appliance breaker must be pushed fully off before it will reset, and a half-reset breaker is a very common cause of a dead machine.
- Close the door firmly and listen for the switch click — A machine that starts after a deliberate close had a door problem and not a control problem.
- Look for a lock symbol or a delay indicator — A machine counting down is not faulty, and the panel usually says so if you look.
What an owner can safely check
- Switch the breaker fully off and then on again — Push it all the way to off first, then back on, and try the machine before going further.
Tools: torchAbout 10 min
- Clean the door catch and strike and close the door firmly — Wipe the catch area, check the strike is not loose, then close the door deliberately rather than gently and try start again.
Tools: soft cloth, screwdriverAbout 15 min
- Clear any control lock and cancel any delay start — Press and hold the lock pad as the manual describes, cancel the programme and select a simple timed cycle.
About 10 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
Switch the machine off at its breaker before reaching inside the cabinet or behind it, and keep it off while your hands are inside. On a gas dryer, shut the gas valve at the machine before moving it, 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 breaker, the door, the control lock and the gas valve have all been ruled out, because what is left is the belt, the door switch, the motor or the control. Describe exactly what the machine does when you press start, because a hum, a click and silence lead a technician to three different places.

This page covers the Daewoo dryer as a class, not one model or production run. Any family- or model-specific page for your unit takes precedence over it. Not here: belt, switch and motor part numbers, and the cabinet disassembly sequence for your specific machine.
