Pool Heater Short Cycling in Mission Valley, 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 Mission Valley, that is worth diagnosing before it turns into a bigger repair. Mission Valley runs on City of San Diego Public Utilities at 12-14 gpg, which is hard water. Around here that means commercial hotel and HOA equipment wear accelerated by valley heat, and it shows up in problems exactly like this one. A specialist in the Refresh Pool Pros network can diagnose it on site in Mission Valley and quote the fix in writing before any work starts.
