Pool Heater Short Cycling in Rancho Santa Fe, CA
A Rancho Santa Fe pool showing a pool heater that keeps shutting off usually has a short list of likely causes. 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 Covenant, the driver worth knowing is estate-scale equipment and automation repair, plus iron staining from well-water properties. A specialist in the Refresh Pool Pros network can diagnose it on site in Rancho Santa Fe and quote the fix in writing before any work starts.
