PC Board for Super Duplex Digital (M-1) - OE# 54091 - Spa Control Replacement Circuit Board

Restore the electronic control functions of your hot tub with the Super Duplex Digital (M-1) Replacement PC Board - OE# 54091, available from Splash Pool & Spa in Peterborough, Ontario.

This replacement printed circuit board is intended for compatible Super Duplex Digital (M-1) spa control systems. As a central component of the hot tub's electronic controls, the circuit board processes signals from connected components and manages supported equipment functions according to the control system's configuration.

A faulty spa circuit board can cause a range of operational issues, including unresponsive controls, equipment that fails to activate, inconsistent heating commands, or communication problems between connected components.

Replacing a confirmed defective circuit board can help restore normal spa operation without requiring replacement of the entire control system, provided the original control pack and replacement board are compatible.

Whether you're repairing an older hot tub or replacing a damaged electronic control component, Splash Pool & Spa supplies spa circuit boards, replacement sensors, heaters, and hot tub electrical parts to customers in Peterborough, the Kawarthas, and throughout Canada.

Product Specifications

Compatibility Information

Before ordering, compare the existing board with the replacement using the OE part number 54091 and Super Duplex Digital (M-1) designation.

Check the board revision, connector layout, equipment configuration, and compatibility with the existing topside keypad and spa control enclosure.

A matching physical appearance does not guarantee electrical compatibility.

Why Replace Your Spa Circuit Board?

The circuit board is an essential part of a spa's electronic control system. When it fails, one or more hot tub functions may stop working correctly.

Replacing the defective board can be a more economical repair than replacing the complete control pack, particularly when the enclosure and other electrical components remain functional and compatible.

Installation safety: Disconnect all power before servicing the spa. Circuit board replacement should be performed by a qualified spa service technician or electrician, with the correct configuration and electrical safety checks completed before operation.
