4055960787 Genuine Terminal Board Assembly, Wiring Terminal Block for Electrolux Group Appliances

A genuine Electrolux terminal board assembly, part 4055960787. A terminal board is the insulated block where wires are joined with screw or clamp terminals, often where the supply cable meets the appliance's internal wiring. Electrolux supplies it as an assembly for its group appliances, and there's no model list on file. Check 4055960787 against your parts list, or compare the terminal count and layout with the old board.

Why terminal boards fail

When a terminal board carries the main supply, all the current the appliance draws flows through it, so a loose screw or poor joint creates heat. Over time that heat can discolour or melt the plastic, char the wire ends and make the connection worse still. Signs include a burning smell, scorch marks around the terminal cover, an appliance that cuts in and out, or a breaker that trips. A damaged terminal board should be replaced rather than just retightened, because heat-damaged plastic no longer insulates properly.

Safety first with terminal boards

Terminal boards carry live connections, so this job is for a licensed electrician, especially on hard-wired appliances. Isolate the circuit at the switchboard and test it's dead before touching anything. Photograph and label every wire, and cut back any wire ends that are blackened or brittle. Tighten each terminal firmly and refit the cover before the power is restored.

Questions about this part

Can I just tighten the old terminal board?

Not if the plastic is scorched, cracked or melted. Heat damage weakens the insulation and the terminals won't hold tightly again, so the board needs replacing. Have a licensed electrician fit 4055960787 and check the supply wiring at the same time.
