An element connection can start to glow if it overheats, which can occur for several reasons:
- Use of Different Materials: If you use regular zinc-plated washers, bolts, or nuts to replace high-temperature stainless steel hardware, or if you opt for standard hardware store wire terminals instead of factory high-temperature wire terminals at the connection point, this can lead to overheating.
- Loose Connections: A connection that isn’t tight enough can heat up because there isn’t sufficient surface area for contact between the parts. Ensure that element connection points are as tight as possible without stripping the threads.
- Excessive Wrapping of Element Tail: The element tail should only wrap around the bolt once, with no overlap. If there’s excess wire, it’s best to snip it off. The element tail generates heat, and wrapping it too many times around the bolt can increase the bolt's temperature.
If you suspect overheating, you'll need to replace the bolt, nuts, and washers, as well as the electrical wire and wire terminal. Check the condition of the element as well; if it looks damaged, it may need to be replaced. Typically, the element wire can withstand high temperatures, but it’s essential to inspect all the other element connections as well.
