Pool Heater Short Cycling in Poway, CA
If you are dealing with a pool heater that keeps shutting off in Poway, you are not alone. A heater that fires then quits after a minute usually has a flow, pressure-switch, or high-limit fault rather than a dead unit. Because Poway pools contend with hard municipal water and well-fed equipment wear across Poway's larger ranch lots, a technician here checks a slightly different list than one at the coast would. The pros we work with cover Poway and can usually get out within the week.
