The short answer
On an NED dryer the usual explanation for no heat is the thermal fuse rather than the element, and the fuse blew because the vent is restricted: replacing it without clearing the duct simply blows the next one. Work the order below rather than the order of expense: the two cheapest checks settle most of these before a tool comes out.
What you actually observe
- The drum turns and the cycle runs, but the air is cold — Power to the motor is fine, power to the heat is not.
- It heated yesterday and not today, with no warning — A thermal fuse or an element failing open rather than a gradual decline.
- A breaker half-tripped or a fuse blown at the panel — One leg missing gives exactly the tumble-with-no-heat presentation.
- Nothing runs at all and the drum does not turn — NEAR MISS: that is a will-not-start fault, covered separately.
- Body: Where a step below depends on which NED listing you own, the table above is the reference; nothing here is written from a model outside it.
Causes, most likely first on the NED platform
- 1. The thermal fuse and the duct behind it — The thermal fuse is a sacrificial part that opens when the exhaust runs too hot, and the reason it runs too hot is almost always a restricted duct. On many machines its opening kills the heat while the drum keeps turning. It ranks first on NED because every listing from NED4600Y*+ to NED5800D** depends on the same duct behind it, and that duct is not part of the appliance.
- 2. The heating element — It is the first cause owners suspect and the second one a technician checks, because a blown fuse presents identically and costs far less. Second on NED because the part above it fails more often and is cheaper to prove.
- 3. One missing leg of the supply — A large appliance circuit is typically 30 A or higher at 240 V, delivered on two legs. The motor runs on one of them, the heat needs both, so losing a leg at the breaker or the outlet gives a dryer that tumbles cold.
- 4. The cycling thermostat — It ranks below the fuse and the element because it is the least common of the three by a wide margin.
What to check first on these NED models, and why
- 1. Note whether the heat stopped suddenly with the drum still turning — That pattern is the fuse's signature on this appliance class.
- 2. Note whether the machine is entirely at room temperature through a full cycle — A cold cycle with a good supply and clear duct points at the element.
- 3. Look at the breaker for a half-tripped double pole — Free, fast, and it explains a tumble-with-no-heat perfectly.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before any panel comes off; a capacitor can hold a charge after the power is off, and a large appliance circuit is typically 30 A or higher at 240 V, which is not a supply to probe casually. Never bypass a thermal fuse or a high-limit thermostat to get heat back: both are there because a restricted duct can start a fire. The NED roster covers six listings, NED4600Y*+ through NED5800D**, and what follows is common to all of them unless a step says otherwise.

When to call a technician
The line is the cabinet. Clearing the duct and checking the breaker are owner work; testing a fuse, an element or a thermostat means a meter on a 240 V circuit and is a technician's job.
