Zodiac - Compressor capacitor 40 μF - B0181400A

Zodiac – Compressor capacitor 40 μF – B0181400A

The Zodiac B0181400A is an OEM replacement compressor capacitor rated at 40 microfarads (μF), designed specifically for use with the Zodiac SIROCCO 110 heat pump. The capacitor is a critical electrical component responsible for starting and running the compressor motor efficiently. It stores and releases electrical energy to provide the initial torque surge required to start the compressor, and continues to support stable motor operation during normal running cycles. Without a properly functioning capacitor, the compressor may fail to start, run erratically, or draw excessive current, leading to potential motor damage.

This is an aluminium-type capacitor, consistent with Zodiac’s catalogue references identifying this part as a compressor aluminium capacitor. The aluminium construction contributes to durability and reliable performance in the demanding thermal environment inside a heat pump unit.

Technical characteristics and compatibility

The B0181400A capacitor is rated at 40 μF, which is the correct specification for the compressor motor fitted to the SIROCCO 110 heat pump model. Capacitance is a precise electrical parameter — fitting an incorrectly rated capacitor can result in poor motor performance, overheating, or premature component failure. This genuine Zodiac spare part ensures the capacitor matches the exact original specification, maintaining the integrity and warranty compliance of your heat pump system.

This part is referenced consistently across multiple official Zodiac and Fluidra product catalogues from 2015 through to 2020, confirming its ongoing relevance as a verified spare component. It is an aluminium electrolytic run capacitor intended for the compressor circuit, distinct from the separate fan capacitor (B0181500A) used in the same heat pump range.

Suitable applications and buying context

This replacement capacitor is intended for pool owners, technicians, and service engineers maintaining or repairing the Zodiac SIROCCO 110 heat pump. It is the correct choice when the existing compressor capacitor has failed — common symptoms include the heat pump failing to start, the compressor humming but not running, or the unit tripping circuit breakers. Replacing the capacitor is typically a cost-effective repair that restores full heat pump function without the need to replace the entire compressor or unit. This is a genuine Zodiac spare part sourced from the official Fluidra/Zodiac parts programme, ensuring fit and performance confidence.
