OEM vs Aftermarket Water Inlet Valve for LG Top Loaders: Honest Comparison (AJU72911001)

Your LG WT-H550 won't fill with cold water, and you're staring at two options on your screen: a $90-$120 OEM valve from an authorized dealer with a 2-week wait, or a $28 aftermarket replacement that ships tomorrow. Here's what actually matters when you're making this call.
Quick Answer
For the AJU72911001 water inlet valve, aftermarket makes sense for 90% of home users. The OEM part doesn't offer enough functional advantage to justify triple the cost and longer wait times. Save the OEM premium for commercial laundromats running 8+ loads daily.

When OEM Makes Sense
There are specific situations where spending extra on the OEM valve is justified. If your washer is still under manufacturer warranty, using aftermarket parts can void coverage—check your paperwork first. For commercial settings like laundromats or rental properties with LG WT-H550 or WTG6534W models running constant cycles, the OEM valve's slightly thicker solenoid housing might handle 15-20 loads per day better over years of abuse.
You'll also want OEM if you're flipping the appliance for resale and buyers specifically ask about all-original parts. Some high-end repair shops only install OEM to maintain their service agreements with manufacturers.
When Aftermarket Wins
For typical home use—even heavy family laundry—aftermarket delivers identical function at a third of the cost. The inlet valve's job is simple: open when energized, close when not. There's no complex calibration or proprietary tech here.
The aftermarket AJU72911001 fits all the same models (WT-H550, WT-H550W1, Kenmore 795.71602013, and dozens more) with the same thread size and mounting bracket. Installation is identical: shut off water, disconnect hoses, swap valve, reconnect. You're not compromising reliability for savings—you're just skipping the brand markup.
The better warranty actually tips this in aftermarket's favor. One year beats 90 days, especially since inlet valve failures usually show up within the first few months if there's a defect.
Our Verdict
Buy the aftermarket valve unless you've got a specific warranty or commercial reason not to. You'll fix your washer this week instead of next, save $60-90, and get better coverage. The OEM part doesn't do anything the aftermarket version can't handle for normal home laundry use.
That price difference buys you a nice dinner out or gets put toward your next repair. The valve works the same either way.
Frequently Asked Questions
Will an aftermarket valve void my LG warranty?
Only if your washer is still covered under the original manufacturer warranty (typically 1 year parts/labor). After that expires, you're free to use any compatible part. For Kenmore-branded LG washers like the 795.71604015, the same rule applies—check your purchase date.
Are the solenoid coils the same quality?
Functionally, yes. Both use standard 120V AC solenoids rated for household water pressure. The OEM might use slightly different wire gauge internally, but it doesn't affect performance for typical 1-2 loads per day use. Commercial environments might see marginally longer life from OEM under extreme duty cycles.
Can I use this valve on my Kenmore washer?
Absolutely. The AJU72911001 is the exact same valve used in Kenmore 71602, 71606, 71609, and the 795.716-series models—they're all LG-manufactured washers with Kenmore branding. The part numbers cross-reference perfectly.
