Zodiac - Compressor aluminium capacitor 80 µF (Eden 4) - B0181900A

Zodiac – Compressor aluminium capacitor 80 µF (Eden 4) – B0181900A

The Zodiac B0181900A is a genuine OEM replacement compressor capacitor designed specifically for the Zodiac Eden 4 heat pump range. This aluminium-cased start/run capacitor carries a capacitance rating of 80 µF, making it the correct electrical component to restore reliable compressor operation when the original capacitor has failed or degraded. As a manufacturer-sourced spare part, it is built to the precise tolerances required by the Eden 4 heat pump, ensuring electrical compatibility and operational safety from the moment of installation.

Capacitors in heat pump compressors serve a critical role: they provide the initial surge of electrical energy needed to start the compressor motor and help maintain smooth running performance under load. When a capacitor fails — a common cause of heat pump compressor faults — the compressor may fail to start, run inefficiently, or draw excessive current that risks damaging the motor. Replacing the capacitor with this exact-specification 80 µF aluminium unit restores the compressor’s ability to start and run correctly, often resolving heating faults without the need for a full compressor replacement.

Technical characteristics and compatibility

This capacitor is housed in an aluminium canister, which offers good thermal dissipation and durability within the confined cabinet of the Eden 4 heat pump. The 80 µF capacitance value is specific to the compressor motor used in the Eden 4 model; fitting an incorrect capacitance value can cause motor damage or premature failure, making it essential to use the correct OEM part. The part number B0181900A is referenced directly in the Zodiac residential catalogue, confirming it as the authorised replacement component for this application. Installation requires basic electrical knowledge and the heat pump must be fully isolated from the mains supply before any work is carried out.

Suitability and application

This spare part is intended exclusively for owners and service technicians maintaining or repairing the Zodiac Eden 4 swimming pool heat pump. It is not compatible with other Eden variants (such as Eden 1, 2, 3, or 5) which use different capacitor ratings — for example, the Eden 1 to 5 fan capacitor is a separate 6.3 µF component. If you are unsure whether this part matches your specific heat pump model and serial number, consult the Zodiac product documentation or contact an authorised Zodiac service centre before ordering. This is a technical electrical spare part and should be installed by a qualified technician.
