About This Item
The Pentair Ignition Control Module (475976) is the OEM replacement ignition control module for the Pentair ETi® 400 Heater. If your heater is failing to ignite or cycling off without establishing a flame, this is the primary control component responsible for managing the ignition sequence.
⚠️ IMPORTANT: LICENSED PROFESSIONAL INSTALLATION 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 governs the ignition sequence of the ETi® 400 Heater — initiating spark, monitoring flame establishment, and shutting down the burner safely if ignition is not confirmed within the operating window. A failed module typically presents as a no-heat condition with no ignition attempt, repeated lockout faults, or a heater that sparks but will not hold a flame.

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 part number on the existing module — it is typically printed on a label affixed to the module body. Confirm it matches 475976 before purchasing. Because the ignition control module interfaces with both gas valve and flame sensing circuits, always have a qualified technician verify the root cause of ignition failure before replacing this component; a faulty flame sensor or gas valve can present with identical symptoms and will not be resolved by replacing the module alone.
