Diagnostic Status Indication

The ignition module has an LED that indicates the status of the ignition safety circuits. The flashing operation of this LED indicates the diagnostic status of the ignition control module. The following listing gives the flashing diagnostic status codes as signaled by the ignition module.

	TABLE - Z
	Ignition Module Status LED Diagnostic Codes
Code Sequence	Condition

Constant ON	System OK, no faults present.
_________________________________________________________________________________________________________
Constant OFF	Possible control fault, check power; LED may be defective, do not replace control if all operational

	sequences function properly - see Trouble Shooting Guide.
_________________________________________________________________________________________________________
One Flash	Low air, check air pressure switch and hoses to pressure sensing points, blower start-up/proving
	blower, venting and sealing of pressurized chamber. Note: Brief flashing normal on blower startup.
_________________________________________________________________________________________________________
Two Flashes	Flame without call for heat, check for a gas valve stuck in the open position, air, venting, burners and

	the combustion process. Blower will remain on.
_________________________________________________________________________________________________________
Three Flashes	Lockout due to flame failure, push reset button on inner 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 2.7 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 18 VAC.
_________________________________________________________________________________________________________
Six Flashes	Replace ignition module, internal fault.
