ATCAP02 Genuine Capacitor 6uF 450V for Glen Dimplex Group Rangehoods, Fan Motor Run Capacitor Replacement

ATCAP02 is a genuine 6uF 450V capacitor from the Glen Dimplex parts range, the kind used with single phase fan motors such as those in rangehoods. It helps the motor start and keeps it running at the right speed. Models aren't recorded for this part, so check that the capacitance and voltage printed on your old capacitor read 6uF and 450V before ordering.

Rangehood motor humming but not spinning

A single phase motor needs a capacitor to give it a push in the right direction and keep the windings working together. When the capacitor weakens or fails, the motor may hum without turning, start only after you spin the fan by hand, run slowly on every speed, or get hot and cut out. A capacitor that has bulged, cracked or leaked is finished. Capacitors are a cheap and common fix for these faults, but if the motor shaft is tight or the windings are burnt, the motor itself needs replacing.

Swapping the capacitor safely

Isolate the rangehood at the switchboard, as many are hard wired, and have a licensed electrician do the work in that case. Capacitors can hold a charge, so discharge the old one safely before handling it. Photograph the wiring, fit the new capacitor in the same position and secure it so it can't vibrate against the housing. Test each fan speed.

Questions about this part

Can I fit a capacitor with a different rating?

Stick with 6uF, as a different capacitance changes how the motor starts and runs. A higher voltage rating than 450V is generally acceptable, but never fit a lower one. Check the markings on your old capacitor before ordering.
