About This Item
The Pentair Ignition Control Module (476223Z) is the OEM replacement ignition control module for Pentair MasterTemp and Max-E-Therm gas heaters — the component that sequences and supervises the igniter and gas valve during each burner start cycle.
IMPORTANT: LICENSED PROFESSIONAL SERVICE REQUIRED
Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification.
The ignition control module manages the ignition sequence each time the heater calls for heat — activating the igniter, monitoring flame sensing, and controlling the gas valve to ensure safe burner operation. When this module fails, the heater will typically fault without igniting or will attempt ignition and lock out after failed trials. Replacing this module with the correct OEM part restores the heater's ability to complete a safe, supervised start cycle.

Poolaroo Pro Tip
Before ordering, locate the ignition control module on your existing heater and confirm the part number printed on its label matches 476223Z. MasterTemp and Max-E-Therm heaters share similar chassis designs across multiple BTU ratings, and ignition control modules are not always interchangeable between models. Verifying the number on your original module — or against the heater's wiring diagram — is the most reliable way to confirm correct fitment before purchase.
