Check for proper line voltage to | Lincoln 1100 Series specs

	Check for proper line voltage to
	the Burner Blower Motor. This
	can be checked at motor connecting
	plug terminal 2 and 5. If voltage is
	present proceed with next step, if not,
	wait 30 seconds, push reset button,
	and try to restart. If this fails, check
	wires from Thermostat and Burner
	Blower Motor to the Ignition Control.
	If all above fails and wires are okay,
	replace ignition control.
Burner Blower Motor	Check for supply voltage to motor.
	WITH POWER OFF: turn blower wheel
	to check for locked rotor.
	If proper supply voltage is present at
	motor connecting plug, terminal 2
	and 5 and motor does not run, replace motor
Air Pressure	Check for proper supply voltage
Switch	switching from “N.C.” to “N.O.” as air
(Burner Blower)	pressure switch closes.
	If above fails, connect a temporary
	jumper wire (FOR TESTING ONLY)
	from terminal “C” to terminal “N.O.”
	on ignition control (bypasses air
	switch). NOTE: For Honeywell
	control only.
	Check for air switch adjustment,
	air tube blockage, or misalignment,
	and if these fail,replace air pressure switch
Spark Generator	A pre-purge-time of 30 to 60 seconds
	occurs after blower motor starts, check for supply
	voltage atspark generator.
	If voltage is not present, check reset
	button for the Ignition Control.
	If voltage is still not present, replace
	ignition control.
	If voltage is present, visually check
	for spark at ignitor head located in
	burner.
Ignitor/Sensor Assembly	Check this assembly for visible
	damage. If there is no damage, replace
	the Spark Generator. If there is
	damage, replace the Ignitor/Sensor
	Assembly. Also check for frayed or
	damaged wires in the burner tube.
Gas Valve	Gas valve should open when
	proper supply voltage is present.
	If no voltage is present, check the
	reset button on the ignition
	control, and all connections for
	tightness. If there is still no
	voltage present at gas valve, replace ignition
	control.If there is voltage present, check for
	gas pressure at the gas pressure tap
	located in the gas piping just prior to
	the burner. If there is no gas pressure, replace
	gas valve
