What the AI looks for in Swimming Pool Heater Parts
- Model, size and serial
- Order by the exact model and BTU size on the rating plate, and check the serial range where the maker revised parts Igniters, control boards and burner trays differ between sizes and revisions.
- Gas type
- Gas valves, orifices and burners must match natural gas or propane as stamped on the heater Mismatched gas parts cause sooting, flame rollout or a failure to light.
- Diagnose before buying
- Read the heater's error code or LED status and check flow, pressure switch and filter condition before replacing a control board Low water flow from a dirty filter is a common cause of pressure-switch faults that get misread as a failed board.
- Safety switches
- Replace the pressure switch, high-limit switch and flow switch with OEM-equivalent units of the same rating; never jumper them These switches keep the heater from firing without water flow or overheating.
- Heat exchanger material
- Copper exchangers need balanced water; cupronickel versions suit salt pools and aggressive water Corrosive water quickly eats copper and voids the warranty.
Brands that matter
- Pentair: OEM parts for MasterTemp, Max-E-Therm and older Minimax heaters.
- Hayward: OEM parts for H-Series and Universal H-Series heaters.
- Raypak: OEM parts for its gas and heat pump pool heaters.
- Sta-Rite: A Pentair-owned brand; many of its heater parts cross-reference to Pentair numbers.
What to avoid
- Universal igniters or boards without a stated heater model list
- Jumpering pressure or high-limit switches
- Changing gas type with loose parts instead of the manufacturer's conversion kit
Questions
Why does my heater show a pressure switch error?
It usually means low flow: a dirty filter, a full pump basket, closed valves or a pump on too low a speed. Check these before replacing the switch.
