The short answer for this family
On the Alliance FDE family, a dryer that will not start at all is usually the supply and the start circuit. Heat on this build is an electric element on a series string with its safety thermostats, so a single open anywhere on that string kills heat without killing the cycle. The brand-generic order holds at the head here; what this platform changes is the order below it. The checks at the head of the ranking cost nothing but time; the cause at its foot is not owner work at any stage.
What you observe on these models
- Which of the family's models you are standing in front of — The matrix on this page is one masked production model, so the whole family is one build, and that is worth reading first, because heat on this build is an electric element on a series string with its safety thermostats, so a single open anywhere on that string kills heat without killing the cycle.
- Nothing at all happens when the cycle is started — No panel light, no click, no motor: that points at the supply rather than at the machine.
- The panel lights but nothing turns — Power is arriving. The fault is in the start circuit, the door circuit or the motor.
- It hums and does not turn — The motor is being asked to run and cannot. That is a seized drive or a motor on the point of failing.
Causes, most likely first on the FDE family
- The supply and the start circuit — Ranked first because heat on this build is an electric element on a series string with its safety thermostats, so a single open anywhere on that string kills heat without killing the cycle.
- The door switch or catch — Second. The element, the high-limit and the thermal fuse all sit on the same duct, reachable from the back panel, so the switch is both the most used and the most reachable part of the start circuit.
- A motor on thermal overload — Third. The tell is timing: it will not start now and it starts an hour later.
- A broken or slipping drive belt — Fourth. Confirmed in seconds by hand, which is why it sits above anything needing a panel off.
- The cycle control, timer or moisture sensor — Last before a service call. Suspect the control once the airflow and the heat path are proven.
- Body: This is not the brand-generic ranking. The head of the ranking matches the brand-generic order, but below it the door switch or catch moves up to second place, because the platform here is a front-load cabinet whose heat is made by an electric element in a duct behind the drum.
Check in this order on these models
- Confirm the machine has its supply — Test the outlet with something else, and check the breaker. A large appliance circuit can trip one side and leave the panel looking alive.
- Open and close the door firmly and listen for the click — No click, no cycle. The door circuit is in series with everything and the switch takes every slam the door gets.
- Leave it an hour and try again — A motor that has cut out on its own protector will start again once it has cooled, and that alone identifies the fault.
- Turn the drum by hand with the power off — A drum that spins free and weightless has no belt on it. A drum that will not turn at all is seized.
- Body: The order follows the ranking, and the access decides the rest: on these models the element, the high-limit and the thermal fuse all sit on the same duct, reachable from the back panel.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel or reaching into the drive area; a capacitor can hold a charge after the power is off. Do not reset a breaker repeatedly: a breaker that trips again is reporting a fault, not misbehaving. On a gas build, close the appliance gas valve before any work inside the cabinet.

Where the owner limit falls on these models
Call when the supply is proven, the door clicks, the drum turns freely by hand and it still will not start. Call promptly if the breaker trips whenever the machine is started, or if the machine hums without turning: both are faults that get worse rather than better with use.
