The Rear Drum Felt Seal with Adhesive is an OEM part for Whirlpool dryers. This part creates a tight seal at the rear of the dryer drum. This seal prevents hot air from escaping the drum during cycles, ensuring efficient and even drying of clothes.  Causes of a deteriorating rear drum felt seal can range from normal wear and tear, excessive heat exposure, to mechanical issues that cause misalignment or excessive wear on the seal itself. Symptoms of a bad Rear Drum Felt Seal include: Clothes taking longer to dry or not drying thoroughly Increased lint outside the dryer or in the venting system Unusual noises during operation, indicating a gap or friction issue Heat escaping from the rear of the dryer This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.This part fixes the following symptomsMarks left on clothesPart Number 279408 (AP3094149) replaces 2018, 279408VP, 3028, 347885, AH334194, DE768, EA334194, K34-917, PS334194.
