Pool Heater Short Cycling in Rancho Peñasquitos, CA
A heater that fires then quits after a minute usually has a flow, pressure-switch, or high-limit fault rather than a dead unit. In Rancho Peñasquitos, that is worth diagnosing before it turns into a bigger repair. Rancho Peñasquitos runs on City of San Diego Public Utilities at 13-15 gpg, which is hard water. Around here that means original 1980s-90s pool equipment failing under heavy family use and hard water scale, and it shows up in problems exactly like this one.
Likely causes in Rancho Peñasquitos
- 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
