About This Item

The Pentair Thermal Fuse (476118Z) is the OEM replacement electrical safety component for the UltraTemp 220 ETi heat pump.

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.

This thermal fuse is part of the UltraTemp 220 ETi's electrical protection system. It interrupts power to the unit if internal temperatures exceed a safe operating threshold, preventing damage to the heat pump's electrical components. A blown thermal fuse will typically prevent the unit from powering on or running normally.

Poolaroo Pro Tip

A tripped thermal fuse is often a symptom rather than the root cause — restricted airflow, blocked venting, or an internal control fault can cause the unit to overheat and trip the fuse again after replacement. Have your service technician verify normal operating temperatures once the new fuse is installed to confirm the underlying issue has been resolved. Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician.
