Zodiac - Compressor capacitor Mitsubishi 7 kW 40µF - B0049500A

Zodiac – Compressor capacitor Mitsubishi 7 kW 40µF – B0049500A

This is a genuine Zodiac replacement compressor capacitor, rated at 40µF, designed specifically for use with Mitsubishi compressor units fitted in Zodiac heat pump models with a 7 kW heating output. The capacitor is an essential electrical component within the heat pump’s refrigeration circuit: it provides the initial surge of electrical energy required to start the compressor motor and helps maintain smooth, efficient operation during running cycles. Without a functioning capacitor, the compressor will typically fail to start or run inefficiently, leading to reduced heating performance or complete system shutdown.

Replacing a faulty or degraded capacitor is one of the most common and cost-effective heat pump repairs. Over time, electrolytic capacitors lose their capacitance due to thermal stress and repeated charge/discharge cycles, causing symptoms such as hard starting, compressor humming without running, or frequent tripping of the overload protection. Installing the correct OEM-specified 40µF capacitor restores the compressor’s electrical characteristics to factory standard, ensuring reliable cold-weather starting and consistent heating performance throughout the swimming season.

Technical characteristics and compatibility

This capacitor carries a capacitance rating of 40 microfarads (40µF), which is the precise value specified for the Mitsubishi compressor used in compatible Zodiac heat pump units rated at 7 kW. Capacitor ratings are compressor-specific: using an incorrectly rated component — even slightly above or below the specified value — can cause excessive motor winding stress, overheating, or premature compressor failure. For this reason, it is important to verify your heat pump model and existing capacitor rating before ordering. The SKU B0049500A is listed across multiple Zodiac and Fluidra pool heating spare parts catalogues, including the 2018 and 2020 editions, confirming its ongoing availability as a stocked OEM replacement part.

Suitability and installation context

This capacitor is intended for pool owners, pool engineers, and maintenance professionals who service Zodiac heat pumps equipped with a Mitsubishi 7 kW compressor. It is a direct OEM replacement, making it straightforward to install in place of the original component with no modification required. As with all work involving heat pump electrical components, replacement should be carried out by a qualified technician, as capacitors store electrical charge and must be safely discharged before handling. This spare part is well suited to preventative maintenance programmes as well as fault-finding repairs, and its OEM origin ensures full compatibility with the original heat pump assembly.
