Ignition control module

This listing identifies a Pentair ignition control module for MasterTemp and Max-E-Therm heaters, part number 42001-0052S.

• Compare your existing board part number with 42001-0052S; similar ignition controls are used across heater families.
• If the failed part is an igniter or gasket, this control module is not the matching replacement.
