Safety Checks You Can Do

Steps you can try at home safely

• Turn off the circuit breaker supplying power to the dryer for 60 seconds, then turn it back on to reset the appliance and clear the error code • Visually inspect the dryer door for any visible damage, warping, or misalignment • Open and close the dryer door slowly several times, listening and feeling for any unusual resistance or gaps • Examine the door frame and latch strike area for accumulated lint, debris, or foreign objects; gently clean with a soft brush or cloth • Check that the door closes completely and latches firmly with an audible click • Inspect the door hinge for visible damage or looseness • Verify all control panel settings are correct and the dryer is set to an appropriate drying cycle • Ensure the dryer has adequate ventilation and the exhaust vent is not blocked • Allow the dryer to cool for 30 minutes if it was recently used, then attempt to restart • Check your home's circuit breaker panel to ensure the breaker for the dryer has not tripped; reset if necessary • If using a 240V dryer model, verify both electrical legs to the dryer are receiving proper voltage (consult your circuit breaker panel)
