If the dryer starts up but you can’t feel the air, the dryer flap may be stuck down. Check the little flap covering the air dryer vent. Occasionally, some dried urine may accidentally splash up causing the flap to stick. Lift the dryer flap and wipe underneath with a damp cloth. If the dryer is blowing cold air please turn the dryer on and adjust the dryer temp using the remote control (ensure the correct buttons are being pressed).
