About This Item

The Pentair Ignition Control Module (476223) is the OEM replacement ignition control module for Pentair MasterTemp and Sta-Rite Max-E-Therm gas pool heaters.

⚠️ IMPORTANT: GAS HEATER COMPONENT — LICENSED PROFESSIONAL REQUIRED
This is a gas appliance ignition and flame-sense control component operating in a high-voltage ignition circuit. 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 and monitors the burner flame signal on MasterTemp and Max-E-Therm gas heaters. It initiates the spark ignition cycle on a call for heat and continuously monitors the flame-sense signal to confirm sustained combustion. If the module fails to detect a valid flame signal within the lockout window, it shuts the gas valve and enters a lockout state — a safety-critical function that protects against unburned gas accumulation. A failed or degraded module typically presents as a no-ignition condition, nuisance lockouts, or an ignition fault code on the heater's display.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

Before ordering, locate the ignition control module inside your heater's control compartment and confirm the part number printed on the module's label matches 476223. MasterTemp and Max-E-Therm heaters have been produced across multiple production revisions, and ignition module part numbers have changed between revisions. The number on the physical module — not the heater's model plate — is the definitive reference. If your existing module carries a different number, cross-reference it against Pentair's current service documentation or contact Pentair technical support to confirm 476223 is the correct current replacement before purchasing.
