Gas and ignition
We test inlet pressure, manifold pressure, ignition sequence, flame signal, gas valve operation, grounding, and safety circuits.
Certified technical service
Jandy Pool Heater Service
Jandy Pool Heater Service for ignition failures, pressure switch faults, heater lockouts, burner issues, sensor problems, gas valve concerns, and poor heating performance. Service is handled by Heating Experts, operated by YKT Inc., with diagnostic-first repair and OEM parts where available.
Repair-first diagnostics
We test the system before recommending parts.
Gas pool heaters fail for a reason. A part replacement alone does not fix low gas pressure, dirty burners, restricted water flow, blocked combustion air, heat exchanger damage, or poor installation conditions.
Heating Experts is operated by YKT Inc. Service is focused on component-level testing, OEM parts where available, and proper startup verification after the repair.
Diagnostic focus
What we check during service.
Burner and heat exchanger
We check burner condition, flame carryover, rust, rollout signs, heat exchanger condition, debris, and venting or air issues.
Water flow and controls
We verify pressure switch operation, flow, bypass condition, temperature sensors, limits, control board faults, and pool system restrictions.
OEM parts and proper setup
Correct parts, correct setup, and proper verification.
Heating and mechanical equipment relies on exact safety tolerances, resistance readings, flame signal values, sensor readings, gasket fitment, timing, and control logic. The wrong part creates repeat failures and safety problems.
Repair sequence
- Confirm the symptom and model information.
- Test the failed circuit or component.
- Quote the correct repair with OEM parts where available.
- Install, set up, and verify safe operation.
Questions customers ask
Common service questions.
Why does my pool heater keep locking out?
Common causes include low gas pressure, dirty burners, weak flame signal, poor water flow, failed sensors, blocked heat exchanger sections, or control faults.
Do you replace parts without cleaning the heater?
Gas pool heater parts fail again when burners, airflow, water flow, or combustion issues stay unresolved. We recommend proper maintenance when the failure points to a dirty or restricted heater.
Do you service Raypak, Hayward, Jandy, and Pentair?
Yes. We service common gas-fired pool heater brands and focus on testing before replacement.
