Pool Heater Short Cycling in Bonsall, CA
Pool Heater Short Cycling is one of the more common calls we get from Bonsall homeowners. A heater that fires then quits after a minute usually has a flow, pressure-switch, or high-limit fault rather than a dead unit. Local conditions matter: in and around San Luis Rey River valley, the driver worth knowing is aggressive calcium scaling from nearly pure Colorado River water eating away at plaster, tile, and pump seals. A specialist in the Refresh Pool Pros network can diagnose it on site in Bonsall and quote the fix in writing before any work starts.
Likely causes in Bonsall
- Low water flow tripping the high-limit or pressure switch
- A dirty filter or closed valve restricting flow
- A failing thermal regulator or flow sensor
- Scale in the heat exchanger from hard water
- A venting or airflow problem on the burner
What to check before you call
- Confirm the pump runs strong and the filter is clean
- Open any valves that feed the heater fully
- Note the error code when it shuts down
- Check for debris blocking the heater intake or vent
