OEM vs Aftermarket LG Refrigerator Evaporator Fan Motor: Real Price Breakdown (EAU64824805)

Your LG refrigerator's freezer is frosting over while the fridge side runs warm. The evaporator fan motor — part number EAU64824805 — just died, and now you're staring at two wildly different price tags. LG's OEM version runs $180–$240 depending on where you look. The aftermarket option? Usually $45–$75. That's a 4x price difference for what's essentially the same 12-volt DC motor.

Let's cut through the noise. I've installed both versions in models like the LMXS28626S, LRFXC2416S, and dozens of other LG French door units. Here's what actually matters when you're deciding.

Quick Answer

For most home repairs, the aftermarket EAU64824805 is the smarter buy — you're getting a functionally identical motor at 25% of the OEM cost. The OEM version offers marginal advantages (slightly quieter operation, LG branding) that rarely justify the 300% markup unless you're doing warranty work or flipping houses where perception matters.

Side-by-Side Comparison

When OEM Makes Sense

There are legitimate scenarios where spending the extra $120–$180 on the OEM motor is worth it:

You're still under LG's manufacturer warranty. If your fridge is less than a year old, using aftermarket parts voids coverage. Pay the premium, let LG handle it, keep your warranty intact.

You're a landlord or property manager. When tenants see the "LG" logo on the replacement part box, it signals quality and reduces complaint callbacks. Perception matters in rental situations.

The fridge is in a bedroom or open-concept space. That first 48 hours of aftermarket motor break-in can produce a noticeable hum. If the unit sits 15 feet from someone's pillow, the OEM's factory-tuned silence might be worth the cost.

You need it TODAY and have an LG service center nearby. Some metro areas have LG parts depots that stock common motors. If downtime costs you spoiled food or business inventory, proximity beats price.

When Aftermarket Wins

For the majority of DIY repairs and service calls, aftermarket is the clear choice:

The motor does the same job. Both versions spin at 1800 RPM, pull the same amperage, and move identical CFM of air across your evaporator coils. The refrigeration cycle doesn't care about branding — it cares about airflow.

You're out of warranty anyway. Once that factory coverage expires, you're paying out-of-pocket regardless. Save $150 and put it toward the next repair (because LG's compressor or defrost system might be next).

Compatibility is proven. This aftermarket motor fits over 80 LG models — from the LRMVS3006S to the LRFDS3016S to the GR-X23FGNGM. The mounting brackets, wiring harness, and blade attachment points are standardized. I've never had one not fit.

Lead time matters more than logo. Most LG dealers need 3–7 days to order the OEM part. Your food is thawing NOW. Aftermarket ships same-day, arrives in 2–3 days, and gets your fridge back online before you lose a week's groceries.

I've replaced maybe 40 of these evaporator fans over the years. Started using aftermarket around repair #15 when I got tired of explaining to customers why a $30 motor costs $220 through LG. Zero failures so far. The motors outlast the fridges.

Installation Reality Check

Both motors install identically — this isn't a "you get what you pay for" situation where the cheaper part requires workarounds:

Unplug the fridge. Non-negotiable. You're working behind live evaporator coils in the freezer.

Remove the back panel. Usually 4–6 screws holding the plastic cover over the evaporator assembly. Models like the LRFXC2416D have clips at the top — lift up, then pull toward you.

Disconnect the wire harness. White 2-pin connector. Squeeze the tab, pull straight back. If it's frozen in place, hit it with a hairdryer for 30 seconds.

Unbolt the motor. Two screws secure the motor bracket to the evaporator housing. Pull the old motor out, slide the new one in, tighten.

Swap the blade if needed. Some aftermarket kits include a blade, others expect you to reuse the old one. Just pull it off the shaft (friction fit) and press onto the new motor.

Total time: 20–30 minutes. No difference between OEM and aftermarket installation.

The Noise Question Everyone Asks

Here's the honest truth: aftermarket evaporator fans CAN be slightly louder for the first 48 hours. The motor bearings need break-in time. You might hear a low hum or slight buzz that wasn't there with the original motor.

But after that break-in period? The noise difference is negligible. We're talking decibel levels you won't notice unless you're standing in front of the open freezer with your ear cocked.

If noise is a dealbreaker — maybe the fridge is in a studio apartment or next to a home office — consider the OEM route. For 99% of installations (garage, kitchen, basement), the aftermarket motor is indistinguishable after a few days.

Our Verdict

Buy aftermarket unless you're under warranty or have a specific noise concern. The $130–$180 you save buys a lot of groceries to replace what spoiled while you waited for an overpriced OEM part. The aftermarket EAU64824805 fits the same, works the same, and lasts just as long. LG's premium pricing reflects branding, not superior engineering.

Compatibility Note

This motor (EAU64824805) replaces LG part numbers Z40E12MS1A0-57K06A, EAU64824806, and EAU63503706. It works across LG's French door, side-by-side, and bottom freezer lines including popular models like:

• LMXS28626S / LMXS28626D
• LRFXC2416S / LRFXC2416D
• LRMVS3006S / LRMVS3006D
• LRSXS2706S / LRSXS2706V
• LRFDS3006S / LRFDS3016S

Check your model number against the full compatibility list, but if you're pulling a fan motor that looks like a small cylindrical motor with a plastic blade and 2-pin connector, this is your part.

Frequently Asked Questions

Will an aftermarket motor void my LG warranty?

Yes, if you're still under the original manufacturer warranty (typically 1 year parts/labor, 5 years compressor). Using non-OEM parts gives LG grounds to deny future warranty claims on related components. Once you're out of warranty, it doesn't matter — use aftermarket and pocket the savings.

How long do aftermarket evaporator fan motors last?

Typical lifespan is 5–8 years with normal use, which matches OEM longevity. These motors fail from bearing wear or thermal stress, not brand name. I've seen OEM motors die in 3 years and aftermarket units run for a decade. Lifespan depends more on how often your defrost cycle runs and whether the drain tube clogs (forcing the motor to work harder).

Can I just buy the motor without the blade?

Most aftermarket kits include the blade because it's cheap to include and eliminates compatibility headaches. But yes, if your existing blade is in good shape (no cracks, spins freely), you can reuse it. Just pull it off the old motor shaft and press-fit it onto the new one. Make sure it's centered and doesn't wobble — an off-balance blade will kill the new motor prematurely.
