Rep Power: 0 | Re: Sundash 252 standup lamp out The capacitors in this unit are for the fans. Brian is most likely right. Check ALL the AMP connectors on the top of the unit. Make sure the pins are all snapped in tight. Also lamp holders go out on this particular unit often. Visual inspection may not always show a problem either testing voltage. If there is a short in the holder you may get voltage but lose it under a load. |

The capacitors are for power factor correction and current draw reduction. The box fans are not capacitor start motors. Only the top fan is and that has a cap mounted locally. You dfo point out another common problem with the lampholders. The internal contacts in the lampholders tend to expand and not make contact with the lamp pin even though they do not look burned and they do tes fine with a voltmeter since you can wiggle the meter probe in there unlike the lamp pin since that will insert in a fixed position. You either have a bad ballast, bad lampholder, or a broken wire in the connecting cord. | |
