Rheem SP10550B Transformer G100MF

This Rheem transformer serves plumbing systems that require a direct replacement for the listed G100MF and GX90 part numbers. It is intended for installers who need a compatible unit without modifying existing wiring or mounting points.

Sustained load behaviour

The component is built to maintain continuous operation in fountain and sink applications where the circuit remains energised for long periods. Its construction supports steady current draw without the thermal cycling that short-burst devices experience.

Practical limits of the interface

The transformer connects only to the manufacturer part numbers shown in the compatibility list, covering models from 37 through 100 series. It cannot be used with unlisted part numbers or with systems that demand a different voltage or mounting configuration.

It replaces the G100MF series and fits models including G37MF, G65MF, G72MF, G75MF, G76MF, G82MF, G85MF, G91MF and GX90 fountains.

Will this SP10550B transformer work with an older Rheem fountain that uses a G75MF or G76MF control board?
