Zodiac – Booster capacitor kit for Z300 MD8 – R07473

The Zodiac R07473 is a genuine OEM replacement booster capacitor kit designed specifically for the Zodiac Z300 MD8 pool heat pump. The capacitor is a critical electrical component within the heat pump’s compressor circuit, responsible for providing the initial surge of energy required to start and run the compressor motor efficiently. Without a correctly functioning capacitor, the compressor may fail to start, run intermittently, or draw excessive current — leading to further component damage. Replacing a faulty capacitor with this genuine Zodiac part restores the heat pump to full operational condition.

Technical characteristics and compatibility

This capacitor kit is engineered to the precise electrical specifications required by the Z300 MD8 heat pump platform. Capacitors in heat pump applications must be matched exactly to the compressor’s voltage and capacitance ratings; using an incorrect component risks motor failure or electrical damage. As a genuine Zodiac spare part, R07473 is manufactured to the same tolerances and quality standards as the original component fitted during production. The kit format ensures that all necessary hardware for installation is included, simplifying the replacement process for qualified service technicians. The Z300 MD8 is a booster-assisted heat pump model, and the capacitor plays a central role in the operation of its compression cycle. Based on available sourcing data, this part is listed at approximately £414, reflecting its role as a specialist OEM electrical component for a premium heat pump system.

Suitability and application

This replacement part is intended exclusively for the Zodiac Z300 MD8 swimming pool heat pump. It is not a universal capacitor and should not be used as a substitute for other models or brands. Installation should be carried out by a qualified pool heating technician or electrician, as working inside a heat pump involves live electrical components. This part is recommended when the Z300 MD8 shows symptoms of compressor start failure, tripping circuit breakers, or abnormal noise during startup — all of which can indicate capacitor degradation. Sourcing a genuine Zodiac replacement ensures full compatibility and preserves the integrity of the heat pump system.
