About This Item
OEM Temperature Control Well for Pentair Heaters
The Pentair RE2058300 is the OEM replacement temperature control well — a 4-3/4" length component designed for the Pentair AP850 heater. If your heater's temperature sensing assembly requires service, this is the direct replacement well.
⚠️ IMPORTANT: HEATER COMPONENT — 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 temperature control well houses the heater's temperature sensing probe, allowing it to monitor water temperature within the heat exchanger circuit without direct fluid contact. A damaged or corroded well can compromise accurate temperature sensing and heater operation. Match the part number stamped on your existing component before ordering.

Pro Tip
Before ordering, verify the part number stamped or engraved on your existing temperature control well. Heater temperature sensing assemblies can vary between production runs and model revisions — confirming RE2058300 against your original part ensures a correct fit. Consult your AP850 heater's installation manual or service documentation for the correct removal and installation procedure, and have a licensed pool technician perform the service.
