Compool CP3800 - Inside Control Panel Dead

[tb40]

So out of nowhere, the indoor / inside panel that controls my Compool cp3800 system went completely dead / dark, no indicator lights on the panel. I took the panel off the wall and disassembled, nothing obviously wrong with the circuit board, wiring etc.

What are the logical steps to start troubleshooting?

I have been reviewing previous posts regarding the compool systems, and some mention a full system reset at the main control box? Also an integrated battery in the control box?

Thank you in advance for any adivce or assistance all!

See the section on Compool. Not sure it will solve your issue, but does give information/trouble shooting.

I would shut power off, take off inside control and hook it up directly to outside panel if you have enough wire to play with. I’ve experienced a lot of low voltage lines broken or oxidizing either going into conduit or sometimes there is a junction box outside the house where it’s fed into the house.

Very helpful, thank you both for your replies.

@Poolbreh - I ended up ordering a replacement 6 conductor RJ12 cable to eliminate the cable from the pool to the house (a long run, perhaps 50 feet) as the issue.

When I hook the inside remote control panel up to the outside panel, should it light up right away with some indicator lights etc? Or do I need to "reset" the outside panel, or turn the breakers on/off???

It should light up right away, if the cable was the problem.

Thank you SO MUCH for your adivse on this issue, as soon as I hooked up the remote panel to the main outside panel using the brand new replacement cable, the panel fired right up, just like you said.

This prompted me to do a much more thorough inspection of the very long signal cable for the remote. Traced it up into the attic and low and behold CHEWED BY A MOUSE (which we had an issue with right when this happed).

Carefully rewired the cable and its fixed!
