Good afternoon, all.
I've been a long time member, but first time poster. I've learned a lot and solved many problems from this forum, so thank you for that. Now that pool season is behind me, I'm posting this in preparation for Spring 2025...
This weekend I was winter prepping various items around my house and came to find a critter beat me to the pool heater. You'll find in the photo below that something found it's way into the control area. Besides the mess and lightly chewed wires (far left red and nearby black), everything else seems to check out. However, when I took it apart to clean properly, I noticed a piece on the circuit board has come off (L10 - photo attached). It doesn't look like it was caused by an animal and I have no clue when it could have happened. I closed the pool mid September and everything ran fine at that time.
My questions... I tried turning the heater on to see if it was still getting power, but nothing came on the display screen. This is the only time I've ever tried to do so without water flow (pool closed), so not sure if anything would show on the display or it remains completely off for safety.
Also, does anyone know what the L10 on the circuit board is? Does it do anything? Is it repairable? Do I need a new board? Etc.
Any information/advice is appreciated. Again, this is for Spring knowledge as we're in winter mode (New York) over here. Thanks in advance.
