Forgive me but I see No resistor or capacitor in the diagram which seems simple enough. Noel.
AH yes, as a single phase motor there could well be a start capacitor, but the resistor ? VFD and new motor would be an expensive way to fix the switch. N
Hi Noel
There is definitely a capacitor,(there is no resistor, just me not knowing before googling)
I can sort of see how to re-wire a new switch but as I have never used a capacitor I wouldn’t know where it would go, I assume on the ‘on live’ side of the switch?
Hi Gary, don’t assume anything – it’s a mystery at the moment. Can you post a photo of the item please. The circuit diagram doesn’t show it, and your description doesn’t help. I think the circuit is incomplete. A picture is worth a thousand words. Any markings on the alleged capacitor? Might be a filter capacitor, which is completely different from a motor Start/Run capacitor.
And which switch do you mean? The diagram shows a reversing switch, two interlock safety switches (boxed in Green below) , and a bunch more built into the contactor (blue box). If by “Switch Block” you mean the contactor, much easier to replace these as a component than to do the same with manual switches.
Needs to be understood before proceeding. I’m sure we can help but more info needed please. I’m baffled!
Ta,
Dave
