Circuit Board FIRE

[jflewis88]

Hello -

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 (see photos). 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!!!

This is usually a good indication of a loose wire connection. When you install new circuit board make sure all connections are tight.
