LG & Kenmore Front Load Washer Tub Seal Parts — Models & Compatibility

If you've noticed water pooling under your LG or Kenmore front-load washer, or caught a whiff of burning rubber during the spin cycle, you're likely dealing with a failing tub seal. This critical component sits between the outer tub and bearing housing, preventing water from reaching the bearings — and when it goes, you'll know it. The 4036ER2003A tub seal fits over 150 LG and Kenmore front-load models manufactured between 2005-2015, making it one of the most universally needed replacement parts for these machines.

Is This the Right Part for Your Model?

Check your washer's model number before ordering. On LG front-loaders, you'll find it inside the door opening along the door frame, usually on the right side. Kenmore models built by LG typically display the model number in the same location. Look for model numbers starting with WM (LG) or 796 (Kenmore Elite series). This seal replaces several OEM part numbers including AP4437693, PS3522854, and AH3522854 — if your original parts diagram shows any of these numbers, the 4036ER2003A is your correct replacement.

About This Replacement Part

The tub seal works harder than almost any other component in your washer. Every load subjects it to friction, detergent chemicals, and constant water exposure. Most seals fail between years 5-8 of ownership, often taking the bearings with them if not replaced promptly. Common warning signs include leaking (water escaping from underneath the machine), loud grinding noises during spin, or that distinctive burning smell caused by the seal material degrading against the spinning tub. This replacement seal is made from durable rubber compound designed to withstand high-speed rotation and repeated water exposure. It's compatible with both 3.5 cu. ft. and 4.0 cu. ft. capacity models across the WM series.

Compatible Model Series

This tub seal fits multiple LG and Kenmore washer series. The WM18, WM20, and WM34 series are the most common applications, along with Kenmore Elite 796 series models that were manufactured by LG. If you own a WD-series model (LG's washer-dryer combo units), this seal fits those as well. The part number 4036ER2003A supersedes earlier versions and provides improved durability over the original factory seal.

Installation Considerations

Replacing a tub seal isn't a quick fix — it requires substantial disassembly including removing the front panel, drum, and spider arm assembly. You'll need to inspect the bearings simultaneously, as seal failure often damages them. Many technicians recommend replacing both bearings and the seal together to avoid doing this job twice. Budget 3-4 hours for the complete repair if you're experienced with appliance work, longer if it's your first time. The seal itself costs $33.99, but you'll likely need bearing grease and potentially new bearings depending on their condition.

Why This Seal Fails

Tub seals wear out from normal use, but certain habits accelerate failure. Overloading the washer puts extra stress on the seal and bearings. Using too much detergent (especially regular instead of HE formula) creates excessive suds that can work past the seal. Hard water deposits can score the seal surface over time. Once water breaches the seal and reaches the bearings, rust develops quickly — that's when you hear the grinding noise. Catching seal failure early, before bearing damage occurs, can save you $100-150 in additional parts.
