The short answer
A Costway compact dryer that does nothing is nearly always a supply or door problem rather than a failed control. These machines are plugged into whatever socket was nearest, and they will not run with the door open. Check the outlet, the lead and the door before you look at anything else.
What you are actually seeing
- No lights and no response at any setting — Means: on-page
- The machine hums but the drum does not turn — Means: on-page
- The machine stops the moment the door is nudged — Means: on-page
- It works on one socket and not on another — Means: on-page
- The machine stopped after a load was overfilled — Means: on-page
- The drum turns but nothing heats — Means: different-fault — Go to: costway-dryer-heating-failure
- A breaker trips when the machine starts — Means: different-fault — Go to: costway-dryer-electrical-safety
- Body: Match what you see before you take anything apart. No lights and no response at any setting. The machine hums but the drum does not turn. The machine stops the moment the door is nudged. It works on one socket and not on another. The machine stopped after a load was overfilled. Some near-miss symptoms belong on a different page: The drum turns but nothing heats points at a heating fault, covered on costway-dryer-heating-failure; A breaker trips when the machine starts points at an electrical fault to stop using the machine over, covered on costway-dryer-electrical-safety.
Causes, ranked for this machine
- No power at the socket, a shared power strip that has tripped, or a switched socket — Why this rank: First because these machines are plugged in wherever there is a socket, and a heater on a shared strip is what trips it
- The door is not closed far enough for the door switch to make — Why this rank: The door switch is an interlock, and a compact door is easily left just short of closed
- A thermal cut-out that has opened after a restricted, overheated cycle — Why this rank: Explains a machine that ran and then would not restart, and it usually accompanies a blocked filter
- An extension lead too light for a heater load — Why this rank: A lead that runs a lamp perfectly is often marginal for a heater and a motor together
- A failed door switch, timer or motor — Why this rank: Last because it needs a part and everything above it is free
- Body: Ranked for a compact or portable dryer on a household outlet: either a vented machine with a short flexible hose, or a ventless machine that collects condensate in a tank or sends it down a drain hose. Most likely: No power at the socket, a shared power strip that has tripped, or a switched socket. First because these machines are plugged in wherever there is a socket, and a heater on a shared strip is what trips it. Next most likely: The door is not closed far enough for the door switch to make. The door switch is an interlock, and a compact door is easily left just short of closed. Third: A thermal cut-out that has opened after a restricted, overheated cycle. Explains a machine that ran and then would not restart, and it usually accompanies a blocked filter. Fourth: An extension lead too light for a heater load. A lead that runs a lamp perfectly is often marginal for a heater and a motor together. Fifth: A failed door switch, timer or motor. Last because it needs a part and everything above it is free.
What to check, in order
- Prove the socket with a lamp and plug the machine in directly
- Close the door firmly and check the machine responds
- Clear the lint filter and let the machine cool before trying again
- Turn the timer firmly to a detent rather than between positions
- Body: Each check rules out the causes above it. First, prove the socket with a lamp and plug the machine in directly. Second, close the door firmly and check the machine responds. Third, clear the lint filter and let the machine cool before trying again. Fourth, turn the timer firmly to a detent rather than between positions.
Checks you can safely make yourself
- Unplug the machine and plug a lamp into the same socket to prove it is live, then plug the machine in directly with no strip — Tools: lamp — Time estimate: a quarter of an hour
- Close the door firmly until it latches and press start, noting whether pressure at one corner makes a difference — Tools: none — Time estimate: a few minutes
- Unplug the machine, clear the lint filter completely and leave the machine to cool for a period before trying again — Tools: brush — Time estimate: half an hour
- Turn the timer or selector firmly into a detent and listen for the motor rather than leaving it between positions — Tools: none — Time estimate: a few minutes
- Remove any extension lead from the path and run the machine straight from a wall socket — Tools: none — Time estimate: a few minutes
- Body: Checks an owner can make with the machine unplugged or by watching a short cycle. Step one: Unplug the machine and plug a lamp into the same socket to prove it is live, then plug the machine in directly with no strip. Tools: lamp. Time: a quarter of an hour. Step two: Close the door firmly until it latches and press start, noting whether pressure at one corner makes a difference. Tools: none. Time: a few minutes. Step three: Unplug the machine, clear the lint filter completely and leave the machine to cool for a period before trying again. Tools: brush. Time: half an hour. Step four: Turn the timer or selector firmly into a detent and listen for the motor rather than leaving it between positions. Tools: none. Time: a few minutes. Step five: Remove any extension lead from the path and run the machine straight from a wall socket. Tools: none. Time: a few minutes.
Safety first
Safety
Unplug the machine before reaching into the drum or moving it, and never tape or bypass a door switch. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Unplug the appliance or switch off its breaker before removing any panel.

Where the owner fix ends
Call for a warranty claim or a technician when the socket is proven live, the machine is plugged in directly, the door latches, the filter is clear and the machine has cooled, and it is still dead. The remaining causes are the door switch, the timer and the motor.

This page is generalized across the Costway compact dryer line. Vented compact tumble dryers, ventless condensing machines and spin extractors share the ranking above but almost none of their parts, and this page does not cover a specific model or control revision.
