Pool Heater Short Cycling in Pacific Beach, 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 Pacific Beach, that is worth diagnosing before it turns into a bigger repair. Local conditions matter: in and around North PB, the driver worth knowing is rental-driven equipment wear and sand infiltration on high-turnover pools. A specialist in the Refresh Pool Pros network can diagnose it on site in Pacific Beach and quote the fix in writing before any work starts.
Likely causes in Pacific Beach

What to check before you call
- Confirm the pump runs strong and the filter is clean
