The short answer
On the Costway EP dryer family a dryer that tumbles without heating is nearly always an airflow story: a restricted exhaust or a blocked lint path overheats the machine, and a thermal cut-out opens to protect it. The brand-generic article opens with the heating element because it covers every chassis; on these models the element is usually innocent and the vent is not.
What you see on the EP family
- The drum turns for a full cycle and the load is still damp — The machine is running perfectly and producing no heat, which is the defining case for this page.
- The load is damp and the machine feels hot to the touch — Heat is being made and is not leaving, which is the airflow case rather than the element case.
- Cycles that used to finish now take much longer — A gradually restricting exhaust shows up as time before it shows up as no heat at all.
- A hot or scorched smell around the machine — Lint accumulated where heat has to escape. Stop the machine and clear it before running anything else.
Causes, most likely first on the EP family
- Heating element or the heat circuit — Ranked first on the EP family — when the vent is clear and the machine has never overheated, the element or its supply is what is left. An element that has burned through makes no heat while everything else runs normally. On a machine fed by two legs, losing one leg leaves tumbling without heat and is a supply fault wearing an element costume.
- Restricted exhaust, lint filter or duct — Second — always near the top, because every other fault on this list is made more likely by a restricted vent. Lint collects in the filter housing, in the duct behind the machine and at the outlet, and a dryer that cannot exhaust cannot dry.
- Thermal fuse or thermal cut-out opened — Third — and inseparable from the first: the fuse opens because the airflow failed, so clearing the vent is part of the repair. A one-shot thermal fuse opens permanently after an overheat and kills the heat circuit, leaving a machine that tumbles cold.
- Thermostat, control board or a moisture sensor misreading — Fourth — and the one to consider once the vent, the fuse and the element are all accounted for. A cycling thermostat that has failed open never calls for heat.
- Body: With only 2 codes in the EP family the ranking below is taken over a short roster rather than over everything the brand sells, which is why the top of this list is not where the brand-generic article puts it.
Check in this order, and why
- 1. Pull the lint filter and look at the housing behind it — Clean the screen and check the cavity underneath, because a filter that looks clear can sit above a packed housing.
- 2. Disconnect the exhaust and run the machine briefly — If it heats with the duct off, the duct is the fault.
- 3. Check the outlet and the breaker — A standard US household branch circuit is 15 A or 20 A at 120 V, and a large appliance circuit is typically 30 A or higher at 240 V; losing one leg of a two-leg supply leaves tumbling with no heat.
- Body: The 2 codes in the EP family are close enough in layout that the order below holds across all of them; check the plate on your own unit against the table before you order anything.
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. Lint is fuel: a machine that smells hot should be stopped and cleared rather than run again to confirm the symptom.

When to call a technician
Call once the filter and the duct are clear and the machine still tumbles cold, because the next steps are the thermal fuse, the element and the supply, and all three sit behind a panel on these models.
