Can I fix a pool heater that keeps shutting off myself?

You can safely run the first checks: confirm the pump runs strong and the filter is clean, and open any valves that feed the heater fully. Anything involving wiring, gas, or a submerged fixture should go to a licensed Palomar Mountain pro.

Does Palomar Mountain water affect this?

Palomar Mountain water is rated moderate at 10-14 gpg, so scale is less of a driver here than coastal air and normal wear.
