4055724043 Genuine Run Capacitor 5uF 400V with Two Small Pin Terminals for Electrolux Group Appliances, Also 1458375

Electrolux part 4055724043, also listed as 1458375, is a genuine run capacitor rated at 5uF and 400V, with two small pin terminals. Run capacitors stay in circuit while a single-phase motor is running, giving it the boost it needs to start and keep turning efficiently. The appliance isn't recorded against this number, so match the capacitance, voltage and terminal style printed on your old capacitor before ordering 4055724043.

Symptoms of a failed run capacitor

When a run capacitor loses capacitance or fails outright, the motor it serves struggles. You might hear a hum as the motor tries and fails to start, see it turn slowly or only after a nudge, or find it running hot and tripping its overload. A capacitor that has bulged, cracked or leaked is finished and should not go back in. Because a weak capacitor causes symptoms that look like a dead motor, it's worth testing the capacitor first, as it's the cheaper part to replace.

Part details

• Genuine Electrolux part 4055724043
• Also listed as 1458375
• 5uF capacitance
• Rated at 400V
• Run capacitor with two small pin terminals

Safe capacitor replacement

Unplug the appliance or isolate the circuit before opening it. Capacitors can hold a charge, so discharge the old one safely before touching its terminals. Note which wire goes to each pin, fit the new capacitor in the same position and secure it firmly so it can't rattle. Never fit a lower voltage rating than the original. Hard-wired appliances need a licensed electrician.

Questions about this part

Can I use a capacitor with a different microfarad rating?

Stick to 5uF for a motor designed around a 5uF run capacitor. A different value changes how the motor runs and can make it overheat. The voltage rating should be the same 400V or higher.
