Pool Heater Short Cycling in Del Mar, 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 Del Mar, that is worth diagnosing before it turns into a bigger repair. Because Del Mar pools contend with aging equipment and plaster wear from salt air and sand infiltration on luxury coastal pools, a technician here checks a slightly different list than one at the coast would. The pros we work with cover Del Mar and can usually get out within the week.
Likely causes in Del Mar

What to check before you call
