Thought I would thank folks who had commented on this one. I found the smoking gun which was small chafe in the insulation between the 2 thermocouple wires. The red wire wore through where it was rubbing against the opposing wire nut. I guess best practice would be to insulate all the T/c connections before attaching the final sleeve. Iíve tried to attach a picture but not sure how well the attachment will come through.

I would place the lock washer under the nut. It looks like the washer is under the screw head...

A star washer should be fitted between the ring terminals as a first course of action as per instructions for this type of connection.
