About This Item
The Pentair Fan Motor with Acorn Nut Kit (473785) is the OEM replacement fan motor assembly for the UltraTemp ETi series pool and spa heat pump. This kit includes the fan motor and acorn nut hardware required for a complete motor replacement.
⚠️ IMPORTANT: KIT INCLUDES MULTIPLE COMPONENTS
This listing is a kit — it includes the fan motor and acorn nut hardware as a complete assembly. This is not a motor-only or hardware-only listing.
⚠️ IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
Electrical and refrigerant-side heat pump components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service high-voltage or refrigerant components without proper certification.
The fan motor drives the condenser fan on the UltraTemp ETi heat pump, circulating air across the heat exchanger to sustain the refrigerant cycle. A failed or degraded fan motor reduces heat transfer efficiency and can trigger high-pressure fault conditions. Replacing the motor as a complete kit — motor and acorn nut hardware together — ensures the assembly is restored to OEM specification.

Pro Tip
Before ordering, confirm the model number on your UltraTemp ETi unit's data plate matches the ULTRATEMP 220 ETi. If your heat pump is a different UltraTemp model or capacity, verify part 473785 is listed in that unit's parts diagram before purchasing — fan motor specifications vary across the UltraTemp product range. When replacing the fan motor, inspect the fan blade for cracks or imbalance and replace it if necessary; a damaged blade can stress a new motor and shorten its service life.
