Pool Heater Short Cycling in Rancho San Diego, CA
Pool Heater Short Cycling is one of the more common calls we get from Rancho San Diego 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. Because Rancho San Diego pools contend with very hard Otay Water District water scaling equipment, plus aging polybutylene pool plumbing, a technician here checks a slightly different list than one at the coast would. The pros we work with cover Rancho San Diego and can usually get out within the week.
Likely causes in Rancho San Diego
- Low water flow tripping the high-limit or pressure switch
- A dirty filter or closed valve restricting flow
- A failing thermal regulator or flow sensor
- Scale in the heat exchanger from hard water
- A venting or airflow problem on the burner
What to check before you call
- Confirm the pump runs strong and the filter is clean
- Open any valves that feed the heater fully
- Note the error code when it shuts down
- Check for debris blocking the heater intake or vent
