Zodiac - Fan capacitor dual Z400 - R0811600

Zodiac – Fan capacitor dual Z400 – R0811600

The Zodiac R0811600 is a genuine replacement dual fan capacitor designed specifically for the Zodiac Z400 heat pump range. Capacitors play a critical role in the operation of heat pump fan motors: they provide the electrical boost required to start the motor and maintain consistent running performance throughout each heating cycle. Without a correctly functioning capacitor, the fan motor may fail to start, run intermittently, or draw excessive current — all of which can lead to reduced heating efficiency or complete system failure. Replacing a worn or failed capacitor with this original Zodiac part restores reliable fan operation and protects the integrity of the heat pump unit.

Technical characteristics and compatibility

The R0811600 is a dual capacitor unit, meaning it services both the normal speed and silence speed fan motor windings within the Z400 heat pump. This dual-function design consolidates two capacitive functions into a single component, simplifying the internal layout of the unit. It is engineered to meet the original electrical specifications of the Z400 heat pump fan motor, ensuring correct start torque and stable running current under typical pool heating operating conditions. As a genuine Zodiac spare part, it is manufactured to the same tolerances as the factory-fitted component, which helps maintain safe and efficient motor operation. Installation should be carried out by a qualified technician, as working inside a heat pump enclosure involves exposure to mains voltage electrical components.

Suitability and application

This capacitor is intended exclusively as a replacement component for the Zodiac Z400 heat pump. It is not a universal capacitor and should not be used as a substitute in other heat pump models or brands without confirming electrical compatibility. The Z400 heat pump is designed for residential outdoor pool applications, and this spare part is suitable for pool owners and service technicians who need to restore full fan motor functionality following capacitor failure. If your Z400 heat pump fan is humming but not starting, running slowly, or failing to operate consistently, a faulty capacitor is a common diagnosis and this genuine part provides the correct like-for-like replacement.
