In short
Taking the TL series on its own, a machine that will not begin resolves most often to power that is not actually arriving. The brand-generic page reaches the same first answer, but the order below it changes on this roster, because reaching the next part is not the same job here. 3 of the 6 causes below can be checked without a tool; the rest need a technician.
What you observe
- It runs only if the door is held closed — A worn catch or switch, which is a cheap part and an easy confirmation.
- Nothing at all: no lights, no sound, no response — Dead is a supply question before it is a machine question.
- The panel lights up but nothing happens on start — The control is alive, so power is arriving and something is refusing to let it run.
- A hum when start is pressed, and no rotation — The motor is energised and cannot turn, which is a belt, a seized part or a start circuit.
- NEAR MISS — it starts and tumbles but does not heat — That is a heating complaint and it belongs on its own page.
Causes, most likely first on the TL series
- Power that is not actually arriving — A standard US household branch circuit is 15 A or 20 A at 120 V, and a large appliance circuit is typically 30 A or higher at 240 V. On a machine fed by two legs, losing one leaves a dead panel or a drum that turns without heat.
- A thermal fuse opened by an earlier overheat — Replacing it without clearing the duct that caused the overheat simply opens the next one, which is why the duct gets checked in the same visit.
- The door switch or a worn catch — No dryer runs with its door reading open. The switch is cheap, it is mechanical, and it is the most common single reason a machine with a live panel refuses to start.
- A broken belt or a seized drum — If the drum turns by hand with no resistance at all, the belt is the answer; if it will not turn at all, something is seized.
- A start switch or control that is not passing the command — Buttons wear out. A panel that lights and responds to everything except start points at the switch or at the control behind it.
- The drive motor or its starting circuit — It is last because everything above imitates it and costs far less to correct.
Check in this order, and why
- Listen for a hum on start — A hum means the motor is getting power. Silence means the circuit to it is open somewhere.
- Check the breaker and the outlet with something else first — It is free, it is fast, and it is what a technician will do before anything else.
- Decide whether the panel has any life at all — A dead panel and a live panel lead down two completely different lists.
- Press start while holding the door firmly closed — It tests the catch and the switch together in about five seconds.
- Only then consider fuses, switches and the motor — All three need a meter and a panel off, and all three are commonly blamed for the causes above.
Before you open anything
Safety
Treat the machine as live until it is unplugged or its breaker is off, and treat it as charged even then — a capacitor holds its charge after the power is off. Lint is fuel. Heat that cannot leave through the duct stays in the cabinet, and a machine running hot with a duct full of lint is how dryer fires start. Put back every panel, clip and cover you take off before the machine goes back on the supply.

When to call a technician
Where to stop: what you can see, reach and clear with the machine isolated is owner work; the element, the fuses and the thermostats, all of which sit behind a panel on a heavy supply is not. On this page that puts a thermal fuse opened by an earlier overheat on the far side of the line.
