Pool Heater Short Cycling in Mira Mesa, CA
Pool Heater Short Cycling is one of the more common calls we get from Mira Mesa homeowners. A heater that fires then quits after a minute usually has a flow, pressure-switch, or high-limit fault rather than a dead unit. Mira Mesa runs on City of San Diego Public Utilities at 12-14 gpg, which is hard water. Around here that means 1980s-era equipment and plaster reaching the end of their service life across the tract, and it shows up in problems exactly like this one. The pros we work with cover Mira Mesa and can usually get out within the week.
