The short answer
A Conservator NTX dryer that tumbles without drying has either lost its heat source or lost the airflow that carries heat through the load, and the two are distinguishable in minutes. The brand-generic page starts by separating no heat from poor drying; that division still governs, and this family sets what follows it. This family is an electric and a gas build of one cabinet, so the heat side of the ranking splits on the plate letter while the mechanical side does not move at all. Read the letter before you read any symptom about heat.
What you observe
- The drum turns and the load comes out cold and wet — No heat at all, which points at the heat source or its thermal protection.
- The load is warm but takes several cycles to dry — Heat is present and airflow is not: moisture is being warmed rather than carried away.
- The cabinet and the room get hot while the machine runs — Heat that is not leaving the machine, which is restriction rather than a heating fault.
- The machine stops part way and restarts after cooling — Thermal protection tripping, which is a consequence of restriction.
- NEAR MISS — no heat and no tumble at all — That is a start, door switch or thermal fuse fault, and it belongs on the will-not-start page.
Causes, most likely first on the NTX models
- Restricted vent, duct or outside hood — First on this family and first by a distance. Airflow does the drying; heat only prepares the air. A machine that cannot exhaust warms the load, warms the room and never finishes, while every component in it tests perfectly.
- Lint filter and internal lint path — Second. A filter that looks clean can still be blinded by a film from dryer sheets, and the path between the filter housing and the blower collects lint that no routine cleaning reaches.
- The heat source named by the plate letter — Ranked here and split by the plate letter, which is what this family table separates. On the electric build it is an element and its thermal protection, and none of the ignition checks written for the gas twin apply.
- Thermal fuse or cut-out tripped — Third. On many machines a tripped thermal fuse stops the heat while leaving the drum turning, which produces the cold-and-wet complaint exactly. It trips because of the first two causes, so replacing it alone repeats the fault.
- Thermostats, timer or control — Last. Worth reaching only once airflow, lint and thermal protection are all confirmed good.
Check in this order, and why
- Establish the heat letter on the plate first — Identify the heat letter on the plate first. On the gas row the ignition sequence is the first thing to observe; on the electric row it is the element circuit, and the two share no parts.
- Feel the exhaust at the outside hood while the machine runs — A strong warm flow means airflow is fine and the question is the heat source. Weak or cool flow means the vent is the fault, whatever the machine is doing internally.
- Clean the filter and then look into the filter housing — The housing collects what the filter misses and it is rarely cleaned at all.
- Disconnect the duct at the machine and run a short cycle — If it heats and dries properly venting into the room, the duct run is the fault and nothing inside the machine needs touching.
- Only then consider the heat source and its protection — By this point the common causes are eliminated, which is what makes a heat-source diagnosis meaningful.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never run the machine vented into the room for more than the few minutes of a diagnostic test, and never run it with a panel off. Clear the lint path completely while you have access: restricted airflow plus a heat source is the exact condition behind dryer fires, which is why this fault is worth fixing rather than working around.

When to call a technician
Call once the vent has been confirmed clear end to end and the machine still will not heat, because what remains is the heat source and its protection behind the cabinet. On the gas build anything past the gas valve is a licensed job. On the electric build the same rule applies to the element circuit once a panel has to come off. Call rather than test if the machine trips its breaker when heat is called for.
