Pool Heater Repair in Bakersfield
Pool heaters are the least forgiving equipment on the pad. They need correct flow, correct gas supply, correct venting and correct water chemistry, and they will refuse to run when any one of those is wrong — which is often the heater protecting itself rather than failing.

How a Heater Works
Water is diverted through a heat exchanger while a burner fires beneath it. A pressure or flow switch confirms adequate water movement before ignition, and sensors monitor temperature and exhaust. Every one of those safeties can shut the unit down, which is why 'the heater is broken' often turns out to be a flow or chemistry issue.
Common Failures
- Ignition failure: igniter, gas valve, flame sensor or gas supply
- Flow-related lockouts from dirty filters, low water or closed valves
- Scaled heat exchangers from high pH and calcium
- Corroded exchangers from low pH or aggressive water
- Failed pressure switches, thermistors and limit switches
- Control board faults and error codes
- Rodent and debris damage inside the cabinet
Chemistry Kills Heaters
The heat exchanger is the most chemistry-sensitive component in the entire system. Hard Bakersfield water and high pH scale it, reducing heat transfer until the unit overheats and shuts down; low pH corrodes it until it leaks. Most premature heater deaths we see are water-balance deaths.
Repair or Replace
Igniters, sensors, switches and valves are routine repairs. A leaking heat exchanger on a heater in its second decade usually is not worth it, since the exchanger is a large share of a new unit's cost. We will show you what we found and let you decide.
Frequently Asked Questions
Why does my heater start then shut off?
Short-cycling commonly indicates flow problems, a scaled exchanger, a failing sensor or a venting issue. It needs diagnosis rather than repeated resets.
Can I fix a heater myself?
No. Heaters combine gas and electricity. Check that the filter is clean and valves are open, then call a professional for anything inside the cabinet.
How long do pool heaters last?
Commonly 8–12 years, heavily dependent on how well the water was balanced.
