The short answer
On the BFLD line, the most common reason a dryer is not starting is door switch or latch not making. On this page that cause is ranked ahead of broken belt or seized idler, which is where the order departs from the brand-generic article above; the ranking below says what about this platform moved it. Three of the four causes below are owner-checkable with no tools worth naming, and the last of them is a service call.
What you see on the BFLD line
- It runs only while the start button is held — That pattern points squarely at the start switch or the motor centrifugal switch rather than at the door.
- It stops the moment the door is nudged — The door switch is marginal — it makes contact when the door is pressed and loses it when the drum vibrates.
- Press start and nothing happens at all — No hum, no drum movement, no click from inside the cabinet — the machine behaves as though it is not plugged in.
- NEAR MISS — it runs but the load comes out wet — That is a heating fault, not a start fault, and the heating page covers it.
Causes, most likely first on the BFLD line
- Door switch or latch not making — A door that closes but does not register leaves the control waiting for a permission it never gets. Usually there is a faint click as the door shuts on a healthy switch, and its absence is the clue. It leads because it is a moving contact operated dozens of times a day, and mechanical contacts fail long before electronics do. The BFLD key covers a single model, so nothing on this page has to be qualified across capacities or configurations.
- Broken belt or seized idler — A seized idler pulley or a failed drum roller can stall the motor outright, which reads at the panel as a machine that will not start rather than one that is jammed. It is on the list because the too-easy drum is a conclusive test that takes seconds and because it explains the noisy-but-motionless version of this fault.
- Power at the outlet, the cord or the breaker — An electric dryer runs on a large two-pole circuit, and half of that circuit can fail while the panel still lights. The result is a machine that looks alive and will not turn. It ranks high because it costs nothing to check and because a partly-dead supply mimics half a dozen internal faults at once.
- Start switch or control board — A start switch that has worn will feel normal and pass nothing. On an electronic machine the same symptom comes from the board that reads it, and telling those apart needs a meter. It sits here because the evidence for it is the absence of every cheaper cause rather than anything you can see.
Check in this order, and why
- First: Open and close the door firmly and listen for the switch click — Press the plunger by hand with the door open and listen for the same click. It comes first because it is the cheapest of the four to exclude and because everything below it is harder to read while it is unresolved.
- Second: Turn the drum by hand with the power off — Almost no resistance means the belt is gone; heavy resistance means something is seized.
- Third: Reset the breaker fully off then on, and check the outlet — A standard household branch circuit is 15 A or 20 A at 120 V, while a large appliance circuit is typically 30 A or higher at 240 V — a dryer sits on the larger one.
- Last: Does it run only while start is held? — If the drum turns at all, the motor is fine and the fault is in what holds the circuit closed.
Before you open anything
Safety
Switch the machine off at the breaker before any panel comes off; a capacitor can hold a charge afterwards. A standard 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, so the terminal block behind a dryer is not a place to probe casually. On a gas dryer, close the gas cock before disturbing anything at the burner.

When to call a technician
The line falls at the meter: the door switch, the breaker, the outlet and the vent are all owner checks, and the start switch, the board and the motor are not. A dryer that hums and will not turn should be switched off rather than retried, because that state heats a winding quickly.
