Call the Pool Heater Repair ExpertsCommon Pool Heater Problems We Fix
If your pool heater won't ignite or keeps locking out, these are some of the issues we fix every day.
Ignition Failure
Your pool's heater won't light or start at all. The igniter may be worn out, the spark electrode is damaged, or the ignition control module has failed.
Common symptoms:
- Clicking sound but no flame
- IF error code on display
- Pool heater attempts ignition then stops
Runs But No Heat
The pool heater appears to operate normally - you hear it running - but the water temperature doesn't increase. Often caused by a stuck gas valve, internal bypass issues, or insufficient gas pressure.
Common symptoms:
- Pool heater sounds like it's running
- No temperature change in water
- No flames visible through sight glass
Flame Sensor Issues
Your pool heater ignites successfully but shuts off within seconds. The flame sensor rod is dirty, corroded, or positioned incorrectly and can't detect the flame.
Common symptoms:
- Lights then immediately shuts off
- Repeated ignition attempts
- Cycles on and off constantly
Pressure & Flow Switch
Low flow or pressure switch errors prevent the pool heater from operating. The switch may be stuck open, or there's an actual flow restriction from a dirty filter or scaled heat exchanger.
Common symptoms:
- LO or PS error codes
- Pool heater won't start despite pump running
- Works intermittently
Heat Exchanger Problems
The heat exchanger is leaking, severely scaled, or corroded. This is especially common in salt pools with copper exchangers or areas with hard water like North Texas.
Common symptoms:
- Water leaking from pool heater cabinet
- Takes much longer to heat than before
- Loud popping or rumbling noises
Control Board Failure
The electronic control board (the brain of your swimming pool heater) has failed due to power surges, moisture damage, or component wear. This typically requires replacement.
Common symptoms:
- No display or lights on control panel
- Random shutdowns or strange behavior
- Multiple error codes appearing
Temperature Problems
Your pool heater won't reach the set temperature, overshoots it significantly, or provides inconsistent heating. Usually caused by a faulty thermistor, high limit switch, or thermostat calibration drift.
Common symptoms:
- Water much hotter or cooler than setting
- HS or HL high limit codes
- Temperature fluctuates unpredictably
Gas Valve & Supply
The gas valve won't open or close properly, or there are issues with gas supply pressure to the pool heater. This is a serious safety concern that requires immediate professional attention.
Common symptoms:
- Strong gas odor near pool heater
- Gas valve makes clicking but won't open
- Weak or irregular flames
Venting & Combustion
Problems with exhaust venting, air intake, or the combustion process itself. You may see soot buildup, smell unusual odors, or get flue sensor fault codes.
Common symptoms:
- Black soot on top of pool heater
- SF or FS error codes
- Yellow or orange flames instead of blue
When to Call a Pro. Safety First
Some checks are safe for homeowners, while others risk gas leaks or electrical damage.

Why Choose Executive Blue Pools for Pool & Spa Heater Repair
Not all swimming pool repair companies are created equal. Many lack the critical licenses, insurance, and manufacturer partnerships needed to properly diagnose, repair, and warranty your pool heater. Here's what sets us apart:
Our Industry Certifications vs. What Others May Be Missing
| Certification We Hold | Why This Protects You | Industry Requirement |
|---|---|---|
| RAIL License Residential Appliance Installer License |
We can legally perform ALL electrical work on your pool heater including control boards, wiring harnesses, transformers, and safety circuits. Many companies operate without this critical license | Required by Texas law; unlicensed electrical work results in $2,000-$5,000 fines and voids insurance |
| CPO® Certification Certified Pool Operator |
Our technicians have proven expertise in water chemistry and safety, not just "learning on the job" like uncertified competitors who may misdiagnose flow or chemistry-related pool heater issues | Industry gold standard; required for commercial pools but many residential services skip this training |
| IPSSA Certification Independent Pool & Spa Service Association |
We maintain advanced troubleshooting expertise and backup coverage; your repair continues even if your assigned tech is unavailable | Optional certification that separates professional services from "splash and dash" operations |
| CSP/PHTA Service Professional Certified Service Professional |
We invest in ongoing education on the latest pool heater technology and diagnostic techniques, while others rely on outdated knowledge and guesswork | Professional credential many budget services don't pursue due to time and cost investment |
| Full Liability Insurance $1M+ coverage from A-rated carriers |
You're protected if anything goes wrong during gas or electrical work, unlike with uninsured "truck and net" operators who leave homeowners at risk | Many operators carry minimal or no insurance, exposing you to liability for gas leaks or electrical damage |

What You Risk with Non-Certified Pool Companies:
- Misdiagnosis and wasted money. Trial-and-error repairs replace expensive parts that weren't the problem
- Aftermarket parts that fail quickly. Off-brand igniters, sensors, and boards often fail within 6-12 months
- Voided manufacturer warranties. Unauthorized repairs or non-OEM parts can void your existing coverage
- No factory support when stumped. Uncertified techs guess instead of calling the manufacturer's engineering team
- Unlicensed electrical work. Gas pool heaters require licensed electrical work. Violations void insurance and create liability
- Weeks waiting for parts. Non-partners wait in line while authorized dealers get overnight shipping
Don't risk your investment with uncertified contractors. Call us for licensed, factory-trained pool & spa heater repairs.
