Pool Heater Not Heating in Lakeside, CA
No heat, short cycling, or an error code usually points to ignition, gas or airflow, or a scaled heat exchanger. In Lakeside, that is worth diagnosing before it turns into a bigger repair.

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. Call and we will connect you with a Lakeside pool pro who finds the real cause, not a guess.
