The Whirlpool WP337186 door spring is an understated yet essential part of your dryer. This tiny metal coil is essential to maintaining the efficient operation of your dryer. The WP337186, which is situated behind the dryer door, attaches to the door latch and tightens a cable. This tensioned wire counteracts the weight of the dryer door when it is opened, preventing it from collapsing or drooping. This guarantees that the door stays firmly closed during drying cycles, preserving the dryer's ideal temperature and ventilation. The genuine Whirlpool WP337186 spring can be used to replace a broken spring and restore proper door tension. This ensures a snug closure for best drying results and smooth laundry routine operation.
