The short answer
Start here -- on an Inglis dryer, a drum that turns without heat points first at a restricted vent run, not at a failed heating element. Second, and worth checking in the same hour, is an opened thermal cutoff. Work the order below -- cheap causes first, the one that is not an owner fix last.
What you are looking at
- The cycle runs much longer than usual — Auto-dry keeps extending and never finishes.
- The machine is hot outside but the clothes are not dry — Heat is being made and not carried away.
- The drum turns and the load stays damp — A full cycle leaves clothes warm and wet.
- NEAR MISS -- the drum does not turn at all — That is a start or drive fault and belongs on another page.
Causes, most likely first on this kind of unit
- The vent run is restricted — Lint in the duct, a crushed flexible hose behind the machine or a blocked outside flap traps hot wet air. The machine overheats, the cutoff opens, and the load comes out warm and damp. First here, because on an Inglis machine: simple controls over standard full-size mechanicals the vent is the part nobody maintains and the one that causes most no-heat calls on any dryer.
- A thermal fuse or cutoff has opened — A restricted vent overheats the machine and the safety device opens -- permanently, on many platforms. The drum still turns, and the heat never comes back until the fuse is replaced and the vent fixed. Placed here: an opened cutoff explains heat that vanished all at once.
- The lint filter is blinded — A filter that looks clean can be sealed by fabric-softener film. Water poured on it will sit rather than run through, and airflow drops enough to trip the cutoff. This rank, because no airflow through the filter means no drying, whatever the element does.
- A cycling thermostat or the control — A cycling thermostat that opens too early, or a control that will not call for heat, needs a meter on live terminals and a wiring diagram. That is where owner checks end. Last, and that is the point of the order: it is the one cause here that is not an owner repair, so it is last.
Check in this order, and why
- Feel the flow at the outside flap — Run the machine and check the outlet; weak or cool flow is a restricted run.
- Ask whether the heat stopped suddenly — Heat that disappeared in one load, with the drum still turning, points at a cutoff.
- Only after vent, filter and supply are proven — Good airflow, a clean filter, both poles live and still no heat is a service call.
What an owner can safely check
- Wash the lint filter and test it with water — Water should run straight through.
Tools: dish soap, brushAbout 15 min
- Disconnect and clear the vent run — Pull the machine out, take the duct off and clear it end to end, including the outside flap.
Tools: vent brush, vacuumAbout 40 min
- Reset both poles of the breaker — Switch the dryer breaker fully off and on; a half-tripped breaker is the classic no-heat cause.
About 5 min
- STOP HERE -- the next step needs a meter on live terminals — Elements, thermostats, cutoffs and gas valves are technician work.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before any panel comes off. If it is a gas dryer and you smell gas: do not switch anything on or off, leave the building, and call the gas utility or emergency services from outside -- do not look for the leak yourself.
When to call a technician
Vent, filter and load are yours; elements, gas valves, thermal cutoffs and bearings are not.

What this page does not cover
This page covers the Inglis dryer as a class, not one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer -- go there first if your model is named. Deliberately not here: element ratings, thermostat part numbers, gas-valve coil sets and the panel-removal order, all of which differ by family.
