CONTACT KIT (Mitsubishi MB0905100)

A worn contact kit can cause intermittent electrical connections, leading to unresponsive controls. Mitsubishi lists this aftermarket replacement part under cross-reference MB0905100. The contact kit serves as a set of electrical contacts that complete a circuit when engaged. Over time, pitting or erosion on the contact surfaces increases resistance and may generate heat. A failed contact kit often results in a complete loss of power to the connected component. Keeping the contact surfaces clean and properly aligned helps maintain reliable switching. Verify the serial number or application, then call (562) 693-7748.
