OEM vs Aftermarket Condenser Fan Motor for LG Refrigerators: Honest Comparison (EAU65058313)

Your LG refrigerator is running warm, and you've traced the problem to a dead condenser fan motor. Now you're staring at two options: a $180-$240 OEM motor from LG Parts, or a $76.99 aftermarket replacement like the Heima EAU65058313. That's a $100+ price gap, and you're wondering what you're actually giving up.

I've installed both types dozens of times on models like the LTCS20020S, LTCS24223S, and LBNC15231V. Here's what you need to know.

Quick Answer

For most homeowners, the aftermarket EAU65058313 is the smarter buy. It's built to the same specifications as the OEM part (replaces EAU63103001, AP7178307, PS16662420), fits the same mounting bracket, uses the same electrical connector, and costs 60% less. The OEM motor makes sense only if you're repairing under warranty or need absolute certainty on a commercial unit.

Side-by-Side Comparison

When OEM Makes Sense

There are three scenarios where I'd spend the extra $100-$160 on the LG factory part:

You're still under LG's original warranty. If your fridge is less than a year old and covered, using an aftermarket part might void remaining coverage. Call LG first — they may cover the motor replacement entirely.

You're repairing a commercial or rental property unit. Some property management agreements specifically require OEM parts for liability reasons. Check your policy before ordering.

You've already had two aftermarket failures. This is rare (I've seen it maybe twice in 20 years), but if you're on your third motor in three years, something else is wrong — voltage spikes, condenser coil issues, or a bad relay. In that case, the OEM part plus a full diagnostic makes sense.

When Aftermarket Wins

For everyone else — and that's 95% of you — the aftermarket motor is the practical choice.

The specs are identical where it matters. The EAU65058313 runs at the same RPM, draws the same amperage, and bolts to the same mounting bracket as the OEM motor. The connector is a direct match — no splicing wires or adapters. On models like the LTCS20220S or LTCS24223W, you literally unbolt the old motor, bolt in the new one, plug it in, and you're done.

Faster delivery when your food is thawing. LG dealers typically need 3-7 days to order the OEM part. Aftermarket suppliers ship same or next day. When you've got $200 of meat slowly defrosting, three days feels like a week.

Better warranty protection. Here's the thing nobody tells you: LG's parts-only warranty is 90 days. The Heima aftermarket motor includes a full year. If the motor fails in month four, you're buying another OEM part at full price — or you're covered free with aftermarket.

The dirty secret about manufacturing. Many aftermarket condenser fan motors come from the same contract factories that build OEM parts. The difference? The aftermarket version doesn't have "LG" stamped on the housing, so they sell it for half the price. You're often getting the same motor without the brand tax.

Installation Is Identical

Both motors install the same way on models like the LRTLS2403S, LTWS24223S, and LBNC15231P series:

1. Unplug the fridge (seriously, don't skip this)
2. Remove the lower rear access panel (four screws)
3. Disconnect the wire harness from the old motor
4. Remove three mounting bolts holding the motor/fan assembly
5. Swap the fan blade if your new motor doesn't include one (one setscrew)
6. Bolt in the new motor, reconnect the harness, test before closing up

The whole job takes 20 minutes. No difference in effort between OEM and aftermarket.

Our Verdict

Save the $100+ and buy the aftermarket EAU65058313 unless you're under warranty or have a specific commercial requirement. After installing both types for two decades, I've seen no meaningful difference in performance or longevity. The aftermarket motor does the same job, ships faster, costs half as much, and includes a better warranty. That's an easy call.

Frequently Asked Questions

Will an aftermarket motor void my LG refrigerator warranty?

If you're still under LG's original manufacturer warranty (typically one year), using aftermarket parts might void coverage for related components. However, once that factory warranty expires, you're free to use any compatible part. For out-of-warranty repairs — which is most DIY situations — aftermarket parts don't affect anything because there's no warranty left to void.

How do I know the EAU65058313 will fit my specific LG model?

This motor replaces OEM numbers EAU63103001, AP7178307, and PS16662420, and it's compatible with 50+ LG and Kenmore Elite models including the LTCS, LTNS, LBNC, LMXS, and LRTLS series. Check the full compatibility list on the product page, or look up your model number. If your fridge originally used one of those OEM part numbers, the aftermarket version is a direct bolt-in replacement.

What if the aftermarket motor fails after a few months?

That's what the one-year warranty covers. Contact the supplier (Heima in this case) with your order number and describe the failure. Most aftermarket suppliers will ship a replacement at no charge if the motor fails within the warranty period. This is actually better protection than LG's 90-day parts warranty. Keep your order confirmation email — you'll need it for any warranty claim.
