Hot Springs Hot Tub Electeic Question

[hottub63]

I took the cover to the control panel off this afternoon to install a new ozone system and when I did I noticed the black wire On the left side of the box looked sort of burned and even had a burned smell to it. Any ideas what is going on? Everything With the hub seems to be working well so I'm not sure if this is causing damage or not. It just doesn't look right.

Any thoughts?

It may have previously fried the heater board and they replaced the board and you're seeing a scorch mark (guessing here). If you know what delaer it came from maybe they can look up the service record for you.

Hmm. Nope. The heater board was never replaced and the heater actually works fine.

Upon closer inspection the plastic around this wire actually is burnt off and you can see the wire. There was even a little bit of a burnt smell when I took off the panel to the control box.

Need a picture.

Picture would be nice.  Is the wire under a lug?  Could be arcing from a loose lug.

Loose connection would be the best guess with information provided. Clip back wire and restrip. Make sure connection point is clean too. Remember - Bright and tight are what you need for electrical connections.
