Power relay LF L3351021

A power relay finder restores control to professional catering equipment when electrical signals fail to reach critical components. In commercial dishwashers, glasswashers, coffee machines and pan washers, the relay acts as a switch that opens or closes a circuit in response to a low-voltage command. When the relay fails, the appliance may stop mid-cycle, refuse to start, or run without heating. This finder does not repair the relay itself; it identifies which relay has failed by isolating the faulty circuit, allowing the operator to replace only the defective part rather than guessing or replacing multiple components.

The relay finder connects temporarily in place of the suspected relay. It carries two exchange contacts rated for 16 A, which match the current the appliance draws during normal operation. When the appliance is switched on, the finder shows whether the relay coil receives the correct voltage and whether the contacts open and close as commanded. If the relay is faulty, the finder will not complete the circuit, confirming the need for replacement.

To use the finder, the operator first disconnects the appliance from the mains supply. The suspected relay is removed from its socket, and the finder is inserted in its place. The appliance is then reconnected and switched on. The operator observes whether the appliance behaves normally—if it does, the relay is confirmed as faulty. If the appliance still fails, the process is repeated with the next relay in the sequence until the faulty one is identified. Once located, the relay is replaced, and the finder is removed.

The LF power relay finder is constructed with a 230 V 50/60 Hz voltage rating, matching the standard supply used in British commercial kitchens. Its contacts are designed to handle the load of heating elements, pumps and motors found in professional catering equipment without overheating or welding shut.

This finder fits a wide range of appliances from over thirty brands, including AMIKA, ANGELO PO, CARIMALI, COLGED, COMENDA, CUPPONE, DESCO, DIHR, ELETTROBAR, ELFRAMO, EMMEPI, EUROWASH, FAGOR, HOBART, HOONVED, KOMEL, LAMBER, MARELS, MBM, OEM, WOLK and ZANUSSI. Specific models include hood-type dishwashers, pull-through dishwashers, glasswashers, cupwashers, pan washers, coffee machines, pizza dough stretchers, dough dividers and warm tables.

The finder is listed in the catalogue under spare parts for electrical control systems in professional catering equipment.
