What this means on these models
On the Criterion CLTE dryer family a drum that turns without heat is an airflow question first and a heat-source question second, because one blower pulls air through the element, through the drum and out to the vent, so every heat fault and every long-cycle fault is an airflow question first. This is the electric variant of the line, so the heat source is an element fed from both legs of the supply. Clear the vent before condemning anything. Written against the one model the spine lists.
What owners of these models actually see
- The dryer, the laundry room or the load smells hot — Heat that is not leaving the cabinet. Stop using it until the vent is cleared, because this is the state in which lint fires start.
- Clothes are warm but take two or three cycles to dry — Heat is being made and not carried away. That is restricted venting, not a failed heat source, and it is the more common of the two by a wide margin.
- The drum turns and the cycle runs, but the load comes out cold and damp — The motor side is fine and the heat side is not. That is the whole diagnosis in one observation, and it rules out half the possible causes.
- NEAR MISS: the drum does not turn at all — That is a start or drive fault with its own list: belt, motor, door switch, thermal fuse. Read that page instead of this one.
What it usually turns out to be here
- The heating element or its circuit has failed — On this electric variant the element needs both legs of its supply. Losing one leg gives a drum that turns perfectly with no heat at all, which is exactly this symptom.
- The vent duct or the lint filter is restricted — First on every dryer and especially here, because one blower pulls air through the element, through the drum and out to the vent, so every heat fault and every long-cycle fault is an airflow question first. A blocked vent both stops the load drying and trips the thermal devices that then look like the fault.
- The supply to the machine is incomplete — A large appliance circuit is rated 30 A or higher, and losing one leg of it leaves the motor running on the other while the element gets nothing.
- A thermal fuse or high-limit device has opened — Ranked high because it is the consequence of the first cause: restricted air overheats the housing, the device opens to protect it, and replacing it without clearing the vent simply repeats the failure.
What to check first, and why in this order
- Clean the lint filter and check the vent hood outside — Run the dryer and put a hand at the outside hood. Weak or no flow there is the answer to most no-heat and slow-dry complaints, and it needs no tools. Each step rules out a cause the next one would inherit.
- Confirm the setting is not an air-only cycle — Air fluff, refresh and some delicate cycles run the drum without heat by design. It costs nothing to rule out and it is more common than anyone admits.
- Check the supply to the machine — An electric dryer needs both legs of its supply: with one leg lost the drum still turns and the element does nothing. A large appliance circuit is rated 30 A or higher.
- Pull the duct off the back and run the machine briefly — If it heats and dries with the duct off, the duct is the fault. This is the single most decisive test on the list. Do not leave it running vented into the room.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Never run the machine with the vent duct discharging into the room for longer than the few seconds of a test. Clear lint from the duct rather than pushing it further in: lint in a hot duct is how dryer fires start.

When this stops being owner work
Cleaning the filter, clearing the duct and checking the setting and the supply are owner work. Call once the vent is proven clear and there is still no heat, because what is left is the element, the thermal devices and the supply. On this platform the machine runs on a high-current supply, so anything behind the panel is worked on with the breaker off and confirmed off.
