Customer Questions and Answers for Dryer Thermal Cut-Off Kit by Whirlpool

Hello David, You should check the air flow out of the back of the unit. If it blows really hard as it is supposed to you should check the exhaust ducting to outside atmosphere. If clogged, restricted, or excessively long, this is causing too much heat to be trapped inside the dryer cabinet and causing the parts to fail. Correcting the dryer duct so it is short and straight as possible and a full 4-inch diameter will not only correct this issue, but will also allow the clothes to dry faster making the dryer last longer, saving time doing laundry, and lowering the electric bill.
