The short answer
On an NEC dryer, no heat is most often the element itself, which fails open and leaves a machine that runs a full cycle at room temperature with nothing else out of order. The causes below are in likelihood order, cheapest first; working down that order costs less than starting with the part that sounds most alarming.
What you actually observe
- The machine is warm to the touch but the laundry stays damp — Some heat and poor airflow, which is the restricted-duct picture rather than a dead element.
- 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.
- The cycle ends and the clothes are hot but still wet — NEAR MISS: heat is present and moisture is not leaving, which is the cycle and airflow page.
- Body: The NEC listings carry a masked suffix in the spine, so the trailing characters on your rating plate will differ from the table without changing the diagnosis.
Ranked causes on these NEC models
- 1. 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. It ranks here because both NEC listings heat the same way, so the same sequence of checks applies to either.
- 2. The thermostat that sets drum temperature — A cycling thermostat that has drifted or failed open gives no heat or feeble heat, and it is the part that sits between the element and the temperature the cycle asked for. Second on NEC because the part above it fails more often and is cheaper to prove.
- 3. The thermal fuse, and the vent that blew it — Replacing it without clearing the duct guarantees a repeat. The fuse is the symptom; the duct is the fault.
- 4. The duct and the outside hood — A blocked duct is the root cause behind most heat failures on this appliance class, because it is what opens the fuses and limits in the first place. It also makes the machine feel hot while drying badly.
Check in this order on the NEC platform
- 1. 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.
- 2. Note whether there is feeble heat rather than none at all — Weak heat rather than no heat moves the fault to the cycling thermostat.
- 3. Note whether the heat stopped suddenly with the drum still turning — That pattern is the fuse's signature on this appliance class.
Before you open anything
Safety
Isolate at the breaker before opening anything, and treat a capacitor as charged after the power is off. A thermal fuse and a high limit are safety devices, never inconveniences, and a machine that has opened one is telling you the duct needs clearing before anything is replaced. Where a step below depends on which NEC listing you own, the table above is the reference; nothing here is written from a model outside it.

When to call a technician
Call once the supply is confirmed at the panel and the duct is clear and the machine still tumbles cold. That leaves the fuse, the element and the limits, all of which are behind panels with a meter on live terminals.
