The answer first
The Artt ATED dryer family covers two listings in the roster below, and on that platform no heat and not enough heat are two different faults. The single most important thing to establish before any part is replaced is why a protective device opened, because replacing it without answering that guarantees the fault returns. Finding why a thermal device opened matters more than replacing it, because a new one without a clear vent lasts a load or two.
The observables
- The drum turns normally and the air is cold throughout — The heating circuit is open somewhere. On an electric machine that is the element, a thermal device or half of the supply; on a gas machine it is the ignition or the gas valve.
- Clothes are warm but still damp at the end of a long cycle — There is heat but not enough air to carry the moisture away, so the load warms without drying.
- The machine works on one heat setting but not another — Individual thermostats or element circuits select different temperatures, so a machine that heats on high and not on low has a selection fault rather than a dead heater.
- A breaker that trips when the machine is started — An element that has failed to earth, or a supply fault. Nothing should be reset more than once, and the machine should not be run while it is happening.
- NEAR MISS — the machine heats but the room is very cold — A dryer in an unheated garage works against colder intake air and takes longer, which is physics rather than a heating fault.
Causes, most likely first on the ATED line
- Restricted vent that has opened a thermal device — Ranked first on the ATED line, because it is both the most common cause of no heat and the reason the part behind it failed, so replacing that part without clearing the vent buys one load and then the same fault returns. Nothing in the roster below splits these listings apart for this fault, so the order that follows holds across the whole label.
- Heating element failed, or gas ignition not completing — Second on the ATED line, because this is the part owners assume has failed, and sometimes it has — an element opens with age, and an igniter, a coil or a flame sensor on a gas machine stops the sequence at a point that can be watched.
- Half of the supply missing on an electric machine — Third on the ATED line, because a dryer that motors on one leg of its supply and heats on both will tumble perfectly and produce no heat at all, which is the single most convincing impression of a dead element there is.
- Cycling thermostat out of specification — Fourth on the ATED line: it produces heat that comes and goes rather than no heat at all, and it sits below the causes above because it is far more often the messenger for an airflow problem than a fault in itself.
- Control board or timer not calling for heat — Last on the ATED line: it is uncommon and because the causes above it explain nearly every no-heat dryer that reaches a technician.
Check in this order, and why
- Check the filter, the housing, the duct and the vent run first — Not as maintenance but as diagnosis: a restricted vent is the most common reason a dryer stops heating, and the evidence is gone once parts start being replaced.
- Compare heat settings and programmes — A machine that heats on one setting and not another has a selection or thermostat fault rather than a dead element, which saves replacing the most expensive part on the list.
- On a gas machine, watch and listen to the ignition sequence — The igniter glowing, the valve opening and the flame holding are three separate events, and the one that does not happen names the part without anything being dismantled.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Lint is fuel and the heating circuit is the ignition source, which is why the vent run is cleared along its whole length rather than at the end that is easy to reach. Do not vent a dryer into the room, and do not run one with a panel off..
Models in the ATED family — Written for the whole roster above rather than for one listing; a page written for a single model would go further than this one does. Model numbers come from the platform data and are reproduced unchanged.

Where the owner side ends
Call for any gas machine whose ignition sequence does not complete, since the burner, the valve and the flame sensing are not owner work at any point. Treat a burnt smell as a stop-now fault: switch off at the wall and leave the machine off until the whole vent run has been inspected.
