The short answer
A DV dryer that does nothing when you press start is a power, door-switch or start-circuit question, in that order. On this family the door switch is the part that fails most often, which moves it above the start switch that the brand-generic page checks first.
What you observe
- A hum with no rotation — The motor is being called and cannot turn, which points at a seized blower or a jammed drum.
- It starts only if the door is pressed hard — A door switch that no longer makes reliably, and it will fail completely soon.
- It starts only when the door is held closed — A door switch that is marginal rather than failed, and it will fail completely soon.
- The panel works but the drum will not turn even empty — Rules out a load problem and points at the start circuit or the motor.
- NEAR MISS - it runs but stays cold — That is a heating fault and belongs on the heating page.
Causes, most likely first on DV
- Door switch worn or not making — Ranked first on the DV family: the switch on this family is worked every load and is the part most likely to have failed when the panel is alive but nothing turns. The order below follows the airflow rather than the wiring, which is a property of the family and not of one machine. What moves against the brand-generic order is lower down: thermal fuse open in the start circuit sits above start switch or the control here, because these models share one layout, so its weak point shows across the whole family.
- No supply at the appliance — Second: a large appliance circuit is typically 30 A or higher at 240 V, and a double breaker can drop one leg while still looking set.
- Thermal fuse open in the start circuit — Third: on this platform the same one-shot device that stops the heat can stop the motor, so a no-start after a hot restricted cycle is very often this.
- Start switch or the control — Fourth: worth proving once the interlocks are clean, but a start switch that has genuinely failed is a rarer find than the two causes above it.
- Seized motor or a jammed drum — Last: last, and the hum with no rotation is its tell; turning the drum by hand with the power off usually settles it.
Check in this order, and why
- Try the breaker and confirm the panel behaves at all — One observation splits the fault: dead panel is supply, live panel is interlock or start circuit.
- Check whether the machine ever heated normally on its last run — A machine that overheated and then died points at the one-shot device in the start circuit.
- Cut power at the breaker for a minute and retry — It clears a latched control state and takes nothing apart.
- Consider the history: did it stop heating first? — A no-heat that became a no-start points at the one-shot protection in the start circuit.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. A thermal protection device that has opened is replaced with the correct part, and only after the restriction that opened it has been cleared: it opened for a reason, and that reason is still there.
When to call a technician
Call once power is confirmed at the appliance and the interlocks are making: what is left is the start circuit, the motor or the protection chain, and all three are tested live inside the cabinet.
