White Knight tumble dryer - drum not turning
Heater comes on no problem (so its not the thermal switch).
When I take belt off the motor does not turn until I give it a slight nudge. If I put the belt back on I still cant get the drum to turn (probably because I cant turn it fast enough to start the motor up). Could this be the capacitor? I've heard that this type of motor uses the capacitor to kick start the motor. To be honest, it started happening but if you left it for 30 mins it would then work OK (capacitor charging?). Now thought theres nothing. My wife insists though that occasionally the dryer stopped half way through. I know its a reverse action so I was wondering if this could be explained by the motor needing to stop and then restart in the opposite direction (using the capacitor). Any ideas ? |

You might want to ask on a.e.electrical - as it is more an electrical problem than electronics or diy. I'm not sure what type of motor this machine has - but would go looking for brush-holders and worn brushes. BICBW -- Sue |

The capacitor is easy to test. What rating is written on it? Assuming it's a mains one, connect it in series with a mains light bulb (something between 40W and 100W), and the light should come on, but not as bright running directly off the mains. Beware in case the capacitor case has become live in some internal failure. However, the nature of the fault you describe sounds to me more like a broken motor winding.

I've heard that this type of motor uses the capacitor to kick start the motor. Dunno what type of motor would be fitted. It could be the capacitor (If it has one). They dry out over a period of time and go open/short circuit. You should be able to get a new one for £3 to £4. If the motor has brushes these could be worn, or the corresponding commutator dirty. sponix |

I've heard that this type of motor uses the capacitor to kick start the motor. It's either the capacitor itself, the starting switch if present, or a fault in the motor. I'd check the switch first, if that works then replace the capacitor, if it still won't start then it's probably the start winding in the motor. |

Whats the difference between a motor run and a motor start capacitor ? None... the difference is the motor the capacitors are the same. No it's not, while you can use an oil filled run capacitor as a start capacitor, you *cannot* use an electrolytic start capacitor as a run capacitor. Start capacitors are rated only for momentary use. |

A capacitor start motor is usually much bigger and has a means of disconnecting the start winding and capacitor once the motor is running, either by the starter or a centrifugal switch. Ah, that's a PSC (permanent split capacitor) motor. Low starting torque but simple, cheap, and generally reliable. |

White Knight tumble dryer - drum not turning UPDATE
OK. Changed the capacitor but now I cant get the motor to run at all
!!!! Just to explain how its connected. From the switch/timer theres one wire straight to the motor, and two to the capacitor. Then two run from the capacitor to the motor. The sole wire is live (I checked). What should be live into/out of the capacitor. Why two wires in and out? Should the motor run with just the one live? What about earth/ground? Can someone explain whats what? (BTW. Think I knackered the timer now though - shorted it and blew the fuses etc.). |

refrigerator compressors dont have a capacitor. Yes, quite a few of them do. I've seen a very few that didn't, but they would be an exception to the rule in my view. William |

So why 4 wires on the top of the capacitor? There are two on one side of the top with a plastic separator between these and two more. Should both inputs be on one side and both outputs on the other? There's probably two pares of terminals, with each pair connected together. This is so you can connect more than one wire to each of the two connections to the capacitor itself. |
