Jacuzzi Blower Motor Bearing Wear / Fan Imbalance

Jacuzzi pool heater operates but the fan is excessively loud or makes grinding/squealing noises.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn blower motor bearings, Debris in blower wheel, Loose mounting hardware, Bent blower wheel blades

Safety first: Turn off power before working near the blower.

Steps to quiet the blower:

Inspect blower compartment: Remove the access panel and check for leaves, twigs, or other debris in the blower wheel.
Check mounting bolts: Tighten any loose screws or brackets securing the blower assembly.
Spin test: With power off, spin the blower wheel by hand. Roughness or grinding indicates bearing wear; the blower motor assembly should be replaced.

Do not lubricate sealed blower motors; replace the unit with a Jacuzzi-approved blower assembly.
