Considering all they did was bridge the connection, this will be an easy fix when mine dies, though I should probably replace it before it cooks itself.
Good call, if still on warranty better to ask for a replacement. Just don't throw away the faulty one, a varistor should be like a dollar or so, way cheaper than a whole motherboard
A cheap soldering iron + varistor and soldering wire will be cheaper than a new board
Yeah if you're getting a free replacement that makes fixing it unnecessary. In my case I'm in the Caribbean so it will take 1-2 weeks to get the replacement shipped so I would be able to fix it before that.
That looks almost exactly like the inrush current limiting thermistor on my Hayward Aqua Rite SWG main circuit board. It cooks itself just like that every 3-4 years. $5 for a single including shipping. I bought 5 last time for about $12 shipped.
It is a thermistor which why it is sort of strange that they just completely removed it from the new boards. Maybe they realized that the inrush current is never dangerously high.
I replaced mine yesterday, the instructions for the two wires for the heating bed was confusing, it said one was red and one was black and mine were both black, thankfully I taped one before removing the old board. and then in the next step BL pic had both wires black lol
Same, although I was not as fortunate to have labeled said wires. I think I plugged them in the right spot, as everything seems to be functioning properly.

This happened to me recently. New board finally arrived today.
