The short answer
Many Costway compact dryers use a mechanical timer and a simple selector rather than an electronic control, so a control complaint is often a timer sitting between positions or a thermal cut-out that has already opened. Establish what your machine actually has before you look for a board that may not exist.
What you are actually seeing
- The timer turns but nothing happens at any position — Means: on-page
- The timer will not advance on its own — Means: on-page
- A digital display, where fitted, shows nothing — Means: on-page
- The machine responds at some settings and not others — Means: on-page
- The control behaves differently after a hot cycle — Means: on-page
- Nothing at all works — Means: different-fault — Go to: costway-dryer-wont-start
- The controls work and the cycle still stops — Means: different-fault — Go to: costway-dryer-cycle-fault
- Body: Match what you see before you take anything apart. The timer turns but nothing happens at any position. The timer will not advance on its own. A digital display, where fitted, shows nothing. The machine responds at some settings and not others. The control behaves differently after a hot cycle. Some near-miss symptoms belong on a different page: Nothing at all works points at a supply failure, covered on costway-dryer-wont-start; The controls work and the cycle still stops points at a cut-out or tank problem, covered on costway-dryer-cycle-fault.
Causes, ranked for this machine
- A mechanical timer left between detents — Why this rank: First because these timers sit between positions easily and produce a machine that appears completely dead
- A thermal cut-out that has already opened, so no setting does anything until the machine cools — Why this rank: Explains a control that worked before a hot cycle and not after it
- A door switch that is not making, gating every setting — Why this rank: The interlock sits ahead of the control, so a marginal door presents as a control fault
- A supply that is intermittent, such as a shared strip or a switched socket — Why this rank: Common on a machine plugged in wherever there was a socket
- A failed timer or control board — 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: A mechanical timer left between detents. First because these timers sit between positions easily and produce a machine that appears completely dead. Next most likely: A thermal cut-out that has already opened, so no setting does anything until the machine cools. Explains a control that worked before a hot cycle and not after it. Third: A door switch that is not making, gating every setting. The interlock sits ahead of the control, so a marginal door presents as a control fault. Fourth: A supply that is intermittent, such as a shared strip or a switched socket. Common on a machine plugged in wherever there was a socket. Fifth: A failed timer or control board. Last because it needs a part and everything above it is free.
What to check, in order
- Turn the timer firmly into a detent rather than leaving it between positions
- Clear the filter and let the machine cool, then try the controls again
- Close the door firmly and check whether the controls come alive
- Prove the socket with a lamp and plug the machine in directly
- Body: Each check rules out the causes above it. First, turn the timer firmly into a detent rather than leaving it between positions. Second, clear the filter and let the machine cool, then try the controls again. Third, close the door firmly and check whether the controls come alive. Fourth, prove the socket with a lamp and plug the machine in directly.
Checks you can safely make yourself
- Turn the timer firmly into each detent in turn and listen for a motor response at each one — Tools: notepad — Time estimate: a quarter of an hour
- Unplug the machine, clear the lint filter and leave it to cool for a period, then try the controls again — Tools: brush — Time estimate: half an hour
- Close the door firmly and repeat the timer test, since the interlock gates every position — Tools: none — Time estimate: a few minutes
- Unplug the machine and plug a lamp into the same socket to prove it is live, then plug the machine in directly — Tools: lamp — Time estimate: a quarter of an hour
- Write down which settings produce a response and which do not, since that maps the fault — Tools: notepad — Time estimate: a quarter of an hour
- Body: Checks an owner can make with the machine unplugged or by watching a short cycle. Step one: Turn the timer firmly into each detent in turn and listen for a motor response at each one. Tools: notepad. Time: a quarter of an hour. Step two: Unplug the machine, clear the lint filter and leave it to cool for a period, then try the controls again. Tools: brush. Time: half an hour. Step three: Close the door firmly and repeat the timer test, since the interlock gates every position. Tools: none. Time: a few minutes. Step four: Unplug the machine and plug a lamp into the same socket to prove it is live, then plug the machine in directly. Tools: lamp. Time: a quarter of an hour. Step five: Write down which settings produce a response and which do not, since that maps the fault. Tools: notepad. Time: a quarter of an hour.
Safety first
Safety
Unplug the machine before removing any control cover. A capacitor can hold a charge after the power is off, and on a compact dryer the timer sits directly on the mains side of the machine. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. unplug-before-service
Where the owner fix ends
Call for a warranty claim or a technician when the socket is proven live, the door closes, the machine has cooled with a clear filter, and no setting produces any response. A timer or a control board sits behind a panel with mains terminals.

Generalized information
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.
