Controls and Electrical Components Academy

Find identification guidance for commercial kitchen and refrigeration switches, relays, control boards, probes, and electrical service parts.

This page is built around verified PartsDirectOnline catalog relationships. It helps service companies, technicians, and commercial foodservice operators move from equipment family to component family, then to relevant collections and replacement part listings.

Identification Focus

Start with the markings on the installed part and the equipment data plate. For commercial equipment, small differences in dimensions, mounting, wiring, controls, and hardware style can determine whether a replacement is correct.
