Yes but when I check continuity between 95 and 96 there is a direct open even after pressing reset. Something appears wrong with overload contacts to keep neutral continuity
Replace the overload block AFTER you have determined what caused the failure. Often enough the coil shorted.
If this is a solid state starter would this make a difference in testing whether overload contacts 95 and 96 were normally closed before heat load is applied?
But we have 6 of these same used starters and they are all doing this. I thought of it more unlikely that they would all fail the same?
Back up and blow the crap out of them as suggested.
I don’t recall that any two contacts were ever closed
That's the way the contacts on the overload work. One set is nc and the other no.
No, neither set of contacts were closed all have OL open circuit on volt meter
Then your OLR is defective and needs to be replaced.
Bad OL Relay, dirty contacts or stuck contacts, See Post #32 or better yet, Post #37
Even if the ol relay is bad one set of contacts is no and the other nc.
Unless there is enough dust build-up to jam the contacts in an artificial neutral position. Of course this is unlikely, especially if it is occurring simultaneously on different OLRs.
