Pool Heater Short Cycling in Oceanside, CA
A Oceanside pool showing a pool heater that keeps shutting off usually has a short list of likely causes. A heater that fires then quits after a minute usually has a flow, pressure-switch, or high-limit fault rather than a dead unit. Oceanside runs on City of Oceanside Water Utilities at 12-14 gpg, which is hard water. Around here that means salt-air corrosion on equipment plus aging Fire Mountain-era pools, and it shows up in problems exactly like this one. A specialist in the Refresh Pool Pros network can diagnose it on site in Oceanside and quote the fix in writing before any work starts.

What to check before you call
