The short answer
On the Arctic Wind AGDG dryer family a drum that turns without heat is much more often an airflow or a thermal-cutout problem than a failed heat source. The roster here is a single listing, AGDG70U. A restricted exhaust overheats the cabinet, a safety device opens to protect it, and the result is exactly this symptom with nothing actually broken except the vent.
What you observe
- The drum turns normally and the load stays cold — No heat is being produced. Points at the heat source, a thermal cutout that has opened, or a supply problem.
- Cycles take far longer than they used to — Gradual loss of airflow. Lint accumulates over months, so the decline is slow enough that nobody notices a day it changed.
- NEAR MISS - the drum does not turn at all — That is a start, belt or motor fault and belongs on a different page for this family.
Causes, most likely first on this roster
- Restricted exhaust duct, vent hood or lint path — First on this roster and the commonest finding on the page. Crushed flexible duct behind the machine, a long run with too many bends, a vent hood flap that no longer opens, or years of lint in the duct all reduce airflow until a cutout opens.
- Blocked lint filter or filter housing — A filter that looks clean can still be blinded by fabric-softener residue, which passes water poorly and is invisible.
- Thermal cutout or thermostat opened — Ranked here because it is very often what is physically wrong while not being the cause. The cause is upstream of it.
- Control, timer or moisture-sensor fault — A moisture sensor reading a load as dry ends the heat early, and a control fault can stop heat being called for at all.
- Body: Ordered by what is found rather than by what is suspected. Lint and duct restriction account for the large majority of no-heat calls on a dryer of any make, and they are also the only entries on the list that are a fire risk in their own right.
Check in this order, and why
- Clean the lint filter and the housing below it — The filter is routine; the housing is not, and lint packs into it where nobody looks.
- Go outside and watch the vent hood while the machine runs — A flap that barely moves is the clearest airflow test available and it needs no tools.
- Disconnect the duct and run a cycle briefly — If heat returns with the duct off, the duct is the fault. Do this only briefly and never as a way to keep using the machine.
- Body: The order below follows the air rather than the parts list. On the AGDG roster the thermal protection is downstream of the airflow, so checking airflow first is what stops a good cutout being replaced for a duct problem.
Safety first
Safety
Unplug the appliance or switch off its breaker before working on it; a capacitor can hold a charge after the power is off. On a gas listing, close the appliance shut-off valve before disturbing any gas fitting, and if you smell gas at any point, leave the building and call the gas utility or emergency services from outside rather than investigating.

When to call a technician
Call once the filter, the housing, the duct and the supply are all confirmed good and the machine still will not heat. On the AGDG roster the next step is inside the cabinet, where the heat source and the thermal devices live. Call immediately for any gas smell, any scorching, or a breaker that trips when heat is called for.
