Common Questions:

Will this work for all 900 series models?
Yes, this Marley 4506-2012-000 is specified for "All Models" within several unit heater series that utilize a 5/8-inch or standard door aperture. Always verify your specific model number against the OEM parts manual to ensure a correct fit.
