How to Find Your Moen Model Number?

Moen garbage disposals’ model numbers are typically printed:

• On the side of the disposal housing
• Near the reset button
• On the bottom label

Are Moen GXP Parts Interchangeable?

Many external components, including mounting assemblies, sink flanges, splash guards, and drain elbows, are generally compatible between GXP33c and GXP50c models. These parts share the same core mounting structure across the GXP series.

However, motor assemblies and internal grinding components are model-specific and cannot be swapped between units. Electrical configurations should also be verified before installing a replacement power cord kit.

Always check the model number printed on the disposal housing to ensure proper compatibility before ordering any replacement parts.

Conclusion

Understanding Moen garbage disposal parts helps you avoid unnecessary replacements and ensures you purchase the correct components for your GXP model.

While many external kits are interchangeable within the GXP series, internal components are model-specific. Always verify your model number and official part number before ordering replacement parts.

Making informed decisions saves money and extends the lifespan of your disposal system.
