220V 50 amp has a tendency to hum (vibrate) power down and retighten connections a couple times a year. Thanks, guru. Will make it a point to do so each time I drain and refill.

Don't even consider this as a solution, you need a #6 wire hi amp connection, not a spade terminal connection, you board is burned up because the person who installed the power leads in the first place did not get them tight enough. Get a new board, cut off any discolored length of the power lead before reconnecting...... end of story Thanks! I have no intention of trying to bypass anything or re-wire anything. I'm comfortable with electricity, but only when going strictly "by the book". A new board, and nice clean tight connections it is! I appreciate the insight, everyone! Thank you!

Thanks, Further. I've added a couple pics per your suggestion. I do hope that it was something as simple as a loose connection. Would bum me out to find that I'd done something so stupid and caused this myself, but certainly better than not knowing (or being able to fix) the problem. As for the Gecko spa pack, that sounds like a great option, but I must admit that I'm not all that savvy with regard to changes/upgrades in components. I've just figured my best bet would be to replace with exact copy, so as to make installation foolproof. I would be happy to change up the entire pack, but don't know the first thing about doing so and making sure it works with my spa. Can you point me to a good resource for learning how to do this properly? Much appreciated and Happy Thanksgiving!!

Hello, All - *** POST MODIFIED TO ADD PICS PER EVEN FURTHER'S SUGGESTION *** Looking for a little information… We have an Infinity Spa, about 5 years old. Went to get in it a couple days ago, there's no power. Check the breaker, it's tripped. This has never happened. Open up the panel, I can immediately smell that something has burnt. Looks like a small fire started at the power connection point, it looks the worst where the black wire connects. It's melted the plastic at the connection point and blackened the surrounding circuitry. I realize this thing is a goner and have located a replacement board. However, before I install a replacement, I'm keen to figure out what caused this???? Don't want to put a new $350 board in there only to have a repeat performance. The tub has worked fine for 5 years. I did replace a pump about 3 months ago, but was very careful to make sure the replacement unit has EXACTLY the same specs as the one it replaced. I'm at a loss as to what might have happened here. Can anyone give me some insight? Thanks!!!
