Understanding the Problem
Brief explanation: If your Kenmore Elite is running but clothes stay damp and the "Vent" or "Check Vent" light is illuminated, the dryer is detecting restricted airflow in the exhaust (or the airflow sensor is faulty). Restricted airflow will reduce drying performance and can trip thermostats or thermal fuses, causing loss of heat. The two most common problems are a clogged vent path (lint build‑up in the lint trap, internal ducting, blower or outside hood) and a failed airflow/vent sensor. Less commonly, a failed heating component (thermal fuse, high‑limit thermostat, heating element or gas components) can either cause no heat or cause the dryer to run longer. Step‑by‑step diagnostic & repair instructions: 1) Confirm the symptom and appliance type - Make sure you know whether this is an electric or gas Kenmore Elite dryer. Gas vs electric changes heating‑component checks (gas igniter/valves vs electric heating element). 2) Basic quick checks (5–15 minutes) - Clean the lint screen: remove the lint screen and clear all lint. Run the dryer on a timed cycle for 2 minutes and feel airflow at the lint filter opening — it should be strong. - Check the outside vent hood: go outside and open the dryer vent hood. Run the dryer and see if there is noticeable airflow and if the flap moves. If little/no airflow, the vent is likely blocked. 3) Test with the vent disconnected (isolates house duct vs internal dryer problem) - Pull the dryer away from the wall and disconnect the duct from the dryer exhaust (unplug first and shut gas valve if gas). Temporarily point the dryer exhaust into a large trash bag or just vent into the laundry room and run a timed cycle with a wet towel. - If the dryer dries normally and the vent light goes out with the duct disconnected, the house vent/ducting or outside hood is the problem. Clean the duct run from the house to the outside. - If the dryer still doesn’t dry and the vent light stays on with the duct disconnected, the fault is inside the dryer (blower wheel clogged, airflow sensor bad, heating fault). 4) Inspect and clean internal airflow path (30–90 minutes) - Unplug the dryer and disconnect gas if applicable. Remove back panel or front panel per model to access lint build‑up. Clean lint from around the lint trap housing, blower housing, and behind the drum using a vacuum and a long dryer vent brush. - Check the blower wheel for packed lint restricting flow. Remove and clean the blower wheel if necessary. - Reassemble and test. Often clearing internal lint restores airflow and stops the vent light. 5) Check the outside vent and ducting thoroughly - Remove the vent hose and inspect for kinks, crushes, or packed lint. Use a long brush and vacuum to clean full length. If ducting is foil accordion type and long, replace with smooth semi‑rigid duct for better flow. - Inspect the outside hood — birds/nests and lint can block the flap. Clean or replace the outside vent hood if damaged. 6) Electrical tests for heating & safety parts (requires multimeter) - If you have good airflow but the dryer still doesn’t heat or takes very long, test the thermal fuse: locate the thermal fuse on the blower housing or exhaust path and check continuity with a multimeter. No continuity = replace thermal fuse. - Check the high‑limit thermostat(s) and the main heating element (electric) or igniter and gas coils (gas) for continuity. Replace any open parts. 7) Vent/airflow sensor or pressure switch diagnosis - If cleaning restored airflow but the vent light remains on, the vent sensor (airflow/pressure switch or electronic sensor) can be faulty. With the dryer unplugged, locate the vent sensor (often located near the lint housing or blower housing). Inspect the small plastic tubing (if present) for blockage or disconnection. - Some models use an electronic airflow sensor on the blower outlet — if the sensor is visibly damaged or you find no change after cleaning, replacing the sensor assembly is the next step. 8) Replace failed parts and retest - Replace any parts that failed continuity tests or are visibly damaged (thermal fuse, thermostats, heating element, vent sensor). Reassemble and run a load test with a wet towel; measure temperature at the exhaust and check drying time. 9) Preventive steps to finish - Replace long, flexible foil ducts with smooth semi‑rigid ducting, install a short, insulated dryer transition, and check/clean the exterior vent hood every 6–12 months. Never run the dryer with the vent closed or blocked. Safety note: Always unplug the dryer (and shut off the gas supply if you have a gas dryer) before accessing internal parts. Testing heating components requires basic electrical knowledge and a multimeter. If you are not comfortable working on gas valves or electrical connections, call a qualified appliance technician.
Common Symptoms
Dryer runs but clothes remain damp, "Vent" or "Check Vent" light on, reduced/no airflow at outside vent, longer dry times, excessive lint build‑up in the trap or behind the drum.
Common Causes
- Clogged lint trap, internal ducting, blower housing, or outside vent
- Restricted, kinked, or crushed dryer duct hose or damaged outside hood
- Failed vent/airflow sensor or pressure switch inside dryer
- Open thermal fuse or high‑limit thermostat, faulty heating element (electric) or igniter/gas coils (gas)
- Blower wheel obstructed by packed lint or debris

Helpful Repair Tip
To confirm a clogged vent vs a bad vent sensor: disconnect the exhaust duct and run the dryer with a wet towel. If drying improves and the vent light goes off, the external vent/duct is clogged. If the vent light stays on, the internal airflow sensor or blower/duct inside the dryer is likely at fault.
Frequently Asked Questions
My vent light stays on after I cleaned the duct outside — what next?
If outside duct and hood are clear but the light stays on, check internal airflow: remove the dryer vent hose and run the dryer. If performance improves, inspect the dryer’s internal ducting, lint trap housing and blower wheel for packed lint. Also check the small plastic tubing and connections to any vent/pressure sensor inside the dryer. If internal airflow is clean and the light still stays on, the vent airflow sensor/pressure switch may be faulty and should be tested or replaced.
Can I keep using the dryer if the vent light is on?
No — using the dryer while the vent light indicates restricted airflow increases drying times and is a fire risk because lint and heat can build up. Stop using the dryer until you clear the blockage or repair the faulty sensor. At minimum, unplug the dryer and clean the lint screen and accessible areas; if the problem persists, perform the diagnostic steps or call a technician.
