    Interference Capacitor

    Doing a favour for the bosses dad this morning. He has a Bosch cooker good that's tripping his RCD. For some unknown reason his kitchen fitters have cut tiles around the hood rather than take it off, tile and refit. He's now selling the house and doesn't want to re-tile so is happy to spend a...

    Capacitor Issues

    I have a Hayward pool pump where the start cap is 161-193 uf. How can you have a range of capacitance. Hayward is an american company. so maybe it can run on 110v or 240v. (just a guess). The other issue is ceiling fan caps, now these are start/run caps and I know from past experience that you...

    Can I use a multi wire capacitor instead of a two wire in a fan??

    Hi Guys, I have a ceiling fan with a two wire 4.5 uf 250V capacitor that has gone bad (fan motor spins very slowly). I cannot find and 2 wire capacitors with this rating (closes is 3 uf) but there are some 5 wire capacitors with one of the connections of the 4.5 rating. Can I use that capacitor...

    Starter Capacitor on bandsaw

    Hi, I removed a start capacitor (burnt out) from my newly acquired bandsaw and did not take a photo of where to replace wires. Apart from the earth there is on left a brown with opposite black/red, next terminal is blue and blue, next is a white with nothing opposite. This junction box is on the...

    When connected to the fan voltage at connectors is 20v when disconnect from fan voltage is 220v. This down to the capacitor?

    Help with choosing replacement capacitor

    I recently had the motor on my Delta dust collector stop working. It was setting off the breaker on the side of motor after just a few seconds of turning on. After researching I discovered the problem with this motor is commonly the run capacitor. When I opened the cover to the capacitor I...

    trying to understand 3 phase motor/capacitor installation

    I'm a qualified mechanic but always tackled small electrical jobs without incident. wonder if i can get some advice re a 60's potters wheel. it consists of : -a 220-250 volt 3 phase, c/s 50, motor -an largish oval capacitor [with a resistor between the 2 contacts] some distance away from...

    Wilo Pump Capacitor Replacement

    Hi All, new member here. I have a Wilo Gold RS50 pump fitted to a solar thermal system. I suspect the capacitor is faulty and wish to replace it. However, I cannot see the method to disconnect one of the capacitor leads (sited between the L & N connections). It is very tight and I don't want to...

    How fast should a capacitor lose it's charge?

    I've been testing some capacitors off a treadmills PCB using a 9 volt battery to charge them up, then taking voltage readings with a multimeter and watching as they discharge. Most seemed to release the 9v very slowly but one 25v 470uF capacitor leaked it away considerably faster than the rest...

    Capacitor Fail?????20 bloody characters.

    motor runs fine if i give it a push. i assume the cap in the pic is a dual start/run. only shows 1 value (4mfd) so does that mean it's 2 x 4mfd caps in the one can? assuming that.best place to get one?

    Inverter went pop, can you identify this film capacitor?

    Hi all. I recently had a 300w inverter go pop and I'd really like to try to repair it if possible (it's a valuable part of a solar energy system). Upon first inspection, the big metallized polypropylene film capacitor right next to the AC output has burnt. I've no idea if there is any further...

    Washing machine capacitor

    Hi all, My washing machine is buzzing which I thought the motor was f&&*Ed but thought to test the capacitor by giving the motor a push start. Starts just fine after which confirms it for me. Anyone know any sites for spare parts? Part number is 11.126/856-324 Not sure if this is the start...
