🛠️ How to Clear the Whirlpool Dryer Check Vent Light
- Vacuum the Blower: Pull out the lint filter and use a long vacuum attachment to reach the blower wheel at the bottom.
- Inspect the Duct: Pull the dryer away from the wall. If the silver tube is squashed, that’s your problem!
- Clean the Exterior: Go outside and ensure the vent louvers open freely when the dryer is running.
- The Drill Brush Method: Feed a cleaning brush through the pipe while spinning it with a drill. You’ll be shocked at how much lint comes out!
- Reset: Unplug the dryer for 10 minutes to clear the control board’s memory.
🤔 Steve’s Quick Troubleshooting FAQ
Q: I cleaned everything, but the Check Vent light won’t turn off. Why?
Steve: Some Whirlpool models require you to run a timed cycle for at least 10 minutes before the sensor resets. If it’s still on, your Outlet Thermistor might be reading the wrong temperature due to a sensor failure rather than a clog.
Q: Is it okay to run the dryer with the “Check Vent” light on?
Steve: I’d say no. It makes your dryer run much hotter than it’s designed to, which wears out the motor and heating element. Plus, it’s a major fire hazard. Take 20 minutes to clean it now and sleep better tonight!
