Right, so not just a polyswitch, it's a MOV as well - so presumably it's had a high voltage up it, and blown the MOV?.

Learn something new every day. I'm not a big fan of MOV's, but an exact replacement is on the shelf at Digi-Key.

ok thank you to everybody, it’s resettable polyswitch, but can’t figure out which one
