Ignition Control Diagnostic Codes
Code Sequence |
| Condition |
|
| |
Constant ON | System OK, no faults present. |
| |||
Constant OFF | Possible | control | fault, | check | power; |
| LED may be | effective, do | not | ||
| replace control if all operational | ||||
| sequences | function | properly, | see | |
| TroubleShooting Guide. |

One Flash | Low Air, check air pressure switch and | ||||
| hoses to pressure sensing points, fan, | ||||
| venting and sealing of pressurized | ||||
| chamber. |

Two Flashes | Flame without call for heat, check for a | ||||
| gas valve stuck in the open position, air, | ||||
| venting, burners and the combustion | ||||
| process. Fan will remain on. |

Three Flashes Lockout due to flame failure, push reset button on outer control panel after correcting ignition problem. Initial heater start up without properly bleeding air from the gas line may require multiple reset functions to achieve proper ignition.
Four Flashes Igniter failure, igniter will not maintain minimum 2.75 amp current draw, caused by low voltage, bad wiring/continuity, high resistance or igniter failure.
Five Flashes Power supply problem, check for low supply voltage or transformer output less than 18VAC.
Six Flashes | Replace ignition module, internal fault. |
circuit, circuit breaker for the control circuit, switching relays for component operation and wiring harness connections to the pool heater’s components. The control panels are common and may be switched between pool heaters for troubleshooting.
Removing the Control Panel
1.Pull the control panel out as far as it will go.
2.Remove the
3.Use a 1/2" box wrench or socket wrench to remove the bolt on the right side of the control panel.
4.Remove the entire control panel.
5.Reinstall the control panel in the reverse order.
CAUTION: Control panel is heavy and awkward to handle when removed. Carefully support the control panel when removing.

Access to Internal Control Panel
The control panel is accessed by turning the knurled knob located at the bottom center of the exterior control panel. Pull the panel out at the bottom. The door will tilt into unit until it comes free from the outer top. The outer control panel has an overlay attached to the exterior surface which indicates the function of each of the pool heater’s indicating lights and a clear window to view the digital temperature display from the temperature control. The thermostat and diagnostic light board are mounted to the back of the control panel door.
The control panel assembly is mounted on a slide out chassis to allow easy access to the components on the panel. The control panel contains the ignition module, transformer for the 24 VAC control
