Product details

Pentair 474323Z is the fan motor kit for the UltraTemp 140, 140C and 140 HC pool heat pumps, supplied with the acorn nut so the fan can be secured on reassembly.

Why the fan matters

A pool heat pump gathers heat from the air. The fan is what pulls that air across the evaporator coil, and without steady airflow the unit has nothing to take heat from. The failure is easy to misread: the compressor still runs, the display looks normal, and the only symptom is that the pool warms slowly or not at all. A motor that has seized, gone noisy, or slowed down produces exactly that picture.

Before you order

This kit is written for the 140 size in three variants: the UltraTemp 140, the 140C and the 140 HC. Check the model plate on the cabinet rather than going by the look of the unit, since the UltraTemp range shares a cabinet across sizes that do not share a fan motor.

Questions and answers

What people ask about this product, answered by our pool techs.

Which heat pumps does this fit?
The Pentair UltraTemp 140, 140C and 140 HC. It is not listed for the other UltraTemp sizes, so read the model plate on the cabinet first.
What is in the kit?
The fan motor and the acorn nut. It is supplied as a kit rather than as a bare motor.
My heat pump runs but barely heats. Could this be it?
It can be. A heat pump depends on the fan pulling air across the coil, so a motor that is seized, noisy or turning slowly cuts the heat output badly even though the unit appears to run.
Is it a genuine Pentair part?
Yes. It is Pentair part 474323Z.
