Coil wires brittle and broke

Submitted a support ticket but my Vulcan just stopped warming up.

Open it up and see the black wire going to the coil isn’t connected. Trying to reconnect and the wire and male/female connections are very very brittle and I think the male tab coming off the coil broke.

I don’t see this holding up much longer. Is there a better way to connect these?

Looks like just a standard spade crimp. High temp spade crimes are available for this purpose, they may have already used them. I wouldn’t just replace the crimp with out cleaning the male part on the heater and some high temp copper grease will help.

My preference would be ring crimp and a bolt. Fit and forget.

Looks like the connections where bad or loose. Make sure you use High temp stainless connections.

Get with @langmuir-sam and I’m sure they will help you out.

Had the same problem several times. Have to tighten regularly just to be safe.

can you post a link to that ring clamp & bolt? I build my own oven and i constantly have this same issue even with using high temp spades. they get so hot they turn brittle and disintegrate.

Just a normal (high temp) ring terminal, McMaster have a selection. We use these on our Injection molding machines with good success, we do however already have a bolt in the junction box to attach them to.

For a heating element that accepts spade crimps, all depends if you are able to drill a hole in end to get a bolt through. Some may already have a hole in the end.
