The summary a technician would give
When a Conservator dryer stops heating, resist the urge to order an element. Check the filter, the hose and the vent first, because a restricted duct is what opens the protector that stopped the heat in the first place. Where a cause needs test gear to confirm, the page says so rather than pretending otherwise.
What the owner sees
- The drum turns and the air is cool throughout — The heating circuit is not working while the motor circuit is, which narrows the fault considerably. Note whether it happens every time or only sometimes, because that distinction narrows the list.
- Clothes are damp and the cabinet is barely warm — The absence of warmth anywhere separates a heating fault from an airflow one. Doing it in this order is what keeps the diagnosis short.
- It happened straight after the machine was moved — A crushed vent hose or a disturbed connection, both of which are caused by the move rather than by wear.
- The vent flap outside barely opens — A direct symptom of the restriction that trips heating protectors in the first place. Do this before the check below it, because the answer changes what that one means.
Where the odds sit
- A thermal cut-out opened by restricted airflow — First because it is what the machine is designed to do when air stops moving, and because the underlying cause is a duct that can be cleared for nothing. It sits above the more dramatic explanations because it is the one you are statistically likelier to have.
- A failed heating element — Common on older machines and the one genuine component failure in the list, but it is diagnosed after the air path rather than before it. Write it down before anybody comes out; a described symptom is worth more than a remembered one.
- A failed thermostat or thermal fuse — These parts open permanently once they have done their job, so the machine stays cold until the part is replaced and the cause cleared. Confirming it costs less than assuming it, which is why it is worth the few minutes.
- On a gas model, an igniter, valve or flame-sensor fault — Last, and specific to gas machines: the ignition sequence has several parts and any of them stops the flame. Note whether it happens every time or only sometimes, because that distinction narrows the list.
How to narrow it down
- Disconnect the vent hose and run the machine briefly — If heat returns with the duct off, the duct is the fault and nothing inside the machine has failed. A result here decides whether the next two checks are worth doing at all.
- Listen for the igniter on a gas machine — Clicking without a flame is a different fault from silence, and it tells a technician where to start. A cause in this position is worth eliminating before you spend anything.
- Note whether it ever heats at all — A machine that heats briefly has a protector cycling; one that never heats has an open circuit. If you can only do one check, make it this one.
The homeowner checks
- Clean the lint filter and wash off any film — Softener residue closes the mesh invisibly, and it is the first restriction in the path. This is safe owner work as long as the power is genuinely off.
Tools: brush, detergentAbout 15 min
- Run a short cycle with the duct disconnected — Do it briefly and with the room ventilated. Repeat it once if the answer is ambiguous rather than moving on with a maybe.
About 15 min
- Check the breaker for the machine — A partly tripped supply can leave the drum turning and the heat off, and resetting it properly costs nothing. Do it with the machine empty rather than mid-load.
About 10 min
- Go no further than this without test gear — That is the boundary between a homeowner check and a service call, and it is not a soft one.

Safety
Pull the plug before anything else; a wall switch is not proof the appliance is dead. Control boards can stay live briefly after the lights go out. Lint is fuel; take it out of the machine rather than pushing it further along the duct. The machine is designed to stop when it is open, and it is meant to stay that way.
When to call a technician
The honest boundary is this. The filter, the hose, the vent and the breaker are yours; elements, thermostats, thermal fuses, gas valves and igniters are not. Past that point, a wrong guess is expensive rather than merely annoying. Get help immediately if a gas model will not light cleanly, and leave the building first if there is any smell of gas.
