Will this fit model FED004815BO by Smart Comfort?

Hello, thanks for your question. We unfortunately can not find a specifications sheet for your Smart Comfort model to confirm that this Revolv coil will fit your unit. However, the Revolv AccuCharge Mobile Home M Series Coil will fit any unit that has close to the same measurements. So it will be compatible with your unit as long as the measurements are close. Provided is the specification guide to the Revolv AccuCharge Mobile Home M Series Coil. If you have further questions we recommend that you give us a call so that we can be of further assistance to you! Thanks.
