Key Features & Performance

Dual Fuel Compatibility: Works with both natural gas and liquid propane MasterTemp/Max-E-Therm heaters.
Direct OEM Replacement: Specifically designed for Sta-Rite MasterTemp and Max-E-Therm models as a genuine OEM part.
Restores Full Control Functions: Includes the ignition module, safety switches, and relay circuitry that manage the heating sequence and ensure proper burner ignition.
Simplifies Repairs: Plug-and-play design is intended to reduce labor time and troubleshooting when swapping out a faulty board.
Engineered for Durability: Built to withstand heat, moisture, and heavy-duty pool/heater environments for lasting performance.
Installation & Compatibility
  • Supersession Note: This part has been updated from P/N 42002-0007S but remains fully compatible with existing MasterTemp/Max-E-Therm heaters.
  • 6-Button Keypad Requirement: The 461105 kit comes with a 6-button membrane keypad; heaters built before 5/7/2021 originally used a 5-button keypad, so confirm keypad compatibility when installing on older units.
  • Connected Heater Update: Heaters manufactured after 5/7/2021 ("Connected Heaters") use the 6-button keypad with RS485 connectivity for IntelliCenter automation; heaters made before that date used the 5-button, non-connected keypad.
  • Serial Number Check: Verify manufacturing date via the heater serial number (day-of-year plus year digits) before ordering to confirm which control board and keypad configuration is required.
  • Related Components: Pairing this board with the correct wiring harness (461107) and ignition control module (476223) ensures proper fit and function during a full electrical system repair.
