Pool Heater Short Cycling in Lakeside, CA
When a Lakeside pool has a pool heater that keeps shutting off, the fix is usually straightforward once the cause is found. A heater that fires then quits after a minute usually has a flow, pressure-switch, or high-limit fault rather than a dead unit. Lakeside runs on Lakeside Water District at 14-18 gpg, which is very hard water. Around here that means iron-heavy well water and hard municipal water corroding aging equipment, and it shows up in problems exactly like this one. A specialist in the Refresh Pool Pros network can diagnose it on site in Lakeside and quote the fix in writing before any work starts.
