Lincoln 1154-000-EA blockage or damage. If above checks are okay, but, Air pressure switch, motor

			blockage or damage. If above checks are okay, but
			pressure switch is still not closed, replace gas valve.
		Air pressure switch	Check air switch terminals for supply voltage to
			terminals NO2 and COM. If voltage is present on one
			side only, check for air tube blockage or misalignment.
			If these are okay, adjust air pressure switch or replace
			if necessary.
		Oven cavity hi-limit thermostat	Terminals are normally closed, opens at 660°F (350°C).
			If open, reset and test oven for proper operation. If
			thermostat will not hold for maximum oven temperature,
			and oven is not exceeding control setting, check for
			proper location of capillary bulb in its spring holder. If
			above checks are okay, replace hi-limit thermostat.
		Ignition control	Check for proper supply voltage to ignition control.
			Check for proper voltage to the burner blower motor.
			This can be checked at motor connecting plug
			terminals 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 the above checks 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 supply
			voltage is present at motor connecting plug terminals 2
			and 5, and motor does not run, replace burner blower
			motor.
		Air pressure switch	Check for proper supply voltage switching from “NC” to
		(burner blower)	“NO” on ignition control. Check for air pressure switch
			adjustment, air tube blockage or misalignment. If these
			adjustments fail, replace air pressure switch.
		Spark generator	A pre-purge time of 30 to 60 seconds occurs after
			burner blower motor starts. Check for supply voltage at
			spark generator. If voltage is not present, check reset
			button for ignition control. If voltage is still not present,
			replace ignition control. If there is input voltage to the
			spark generator, but there is no high voltage output,
			replace the spark generator.
		Igniter/sensor assembly	Check this assembly for visible damage. Replace as
			needed. If there is no visible damage, check for voltage
			supply to igniter/sensor assembly. If there is voltage
			supplied to the igniter/sensor, but there is no spark,
			replace igniter/sensor assembly.
		Gas valve	Gas valve should open when proper supply voltage is
			present. If there is no voltage present, check reset
			button on ignition control, and all connections for
			tightness. If there is still no voltage to gas valve,
			replace the ignition control. If there is voltage to the gas
			valve, 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 the gas valve.
	Flame will not stay on	Flame sensor	To check for flame sensor operation, connect a digital
			multimeter (capable of measuring DC microamps)
			between the flame sensor wire and terminal #1 on the
			ignition control. Sensor current is to be 3 microamps,
			minimum. If these readings are not achieved, replace
			igniter/sensor assembly. Also check for any type of
			damage to flame sensor wire and connections.
			NOTE: The DC microamp test must be conducted with
			the oven in low flame (bypass) operation.
