Pool Heater Short Cycling in Coronado, 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 Coronado, that is worth diagnosing before it turns into a bigger repair.
Likely causes in Coronado
- 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
