Description
Product Overview
The Ohmmonburged 55 MFD garage door opener capacitor is a precision‑engineered component designed to meet the exact electrical requirements of legacy LiftMaster 30B532 opener systems. With a capacitance of 55 µF and a voltage rating of 250 V, this capacitor provides the necessary start‑up boost and run‑time stability for single‑phase ½‑HP motors commonly found in residential garage door applications. Constructed from high‑quality CBB60 aluminum electrolytic material, the unit offers a tolerance of ±5 % and a robust physical design that resists vibration, temperature fluctuations, and moisture ingress. The dimensions measure 1.7 × 1.7 × 3.8 inches and the weight is a lightweight 3.84 oz, allowing for straightforward handling and installation. Compatibility is limited to older LiftMaster models that use the larger‑diameter capacitor form factor; it will not fit newer K030B532‑1 designs, ensuring that users select the correct part for their specific opener model. The product carries the Ohmmonburged brand, known for reliable aftermarket electrical components, and meets industry standards for safety and performance. Detailed specifications include a withstand voltage of 250 V, a temperature rating suitable for typical garage environments, and a long service life that reduces the need for frequent replacements.

Usage
This capacitor is intended for residential garage door opener systems, particularly those equipped with older LiftMaster 30B532 units. It is also fully compatible with other major brands that share the same electrical specifications, such as Chamberlain and Craftsman 1/2‑HP opener motors. Installation is performed by disconnecting power to the opener, removing the existing capacitor, and mounting the new Ohmmonburged unit in the same location, ensuring correct polarity and secure connections. The capacitor’s design supports both start‑up and run‑capacitor functions, making it suitable for applications where the motor requires an initial surge of power to overcome inertia and then a steady supply for continuous operation. Users can expect quieter operation, reduced wear on motor components, and a lower likelihood of opener failure due to capacitor degradation. The product is also suitable for single‑phase motor applications beyond garage doors, such as small workshop equipment that utilizes similar motor configurations. Proper installation and periodic inspection will maximize performance and extend the lifespan of the garage door system.
