Lincoln 1155-000-EA achieved, replace ignition control, connections, NOTE Flame should be on at

			shorts. Readings should be as follows, V1 – 2.9K ohms
			approx., V2 – 1.3K ohms approx. If these readings are
			not achieved, replace gas valve. If these readings are
			achieved, replace ignition control.
	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 the flame sensor
			connection on the ignition control. Sensor current is to
			be 0.9 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.
		Power supply	Set the temperature to the lowest temperature setting.
			If there is sufficient microamp current, but the flame will
			not stay lit, check for proper polarity of the power
			supply.
		Ignition control	If there is sufficient microamp current, and there is
			proper polarity of the power supply, but the burner will
			not stay lit, check the reset button on the ignition
			control. If the above test is okay, replace the ignition
			control.
		NOTE: Flame should be on at
		this time
	Low flame is on, but	Control transformer	Check for supply voltage to the primary of control
	no main flame		transformer. If no voltage is present, trace wiring back
			to oven fan switch. If voltage is present, check for
			24VAC at transformer secondary. If there is primary
			voltage, but no secondary voltage, replace control
			transformer.
		Conveyor motor	Check for supply voltage to the conveyor motor at
			terminal #6 to neutral. If no voltage is present, trace
			wiring back to the oven fan switch. If voltage is present,
			but the motor will not run, check the motor windings for
			opens or shorts. If any of the above fail, replace the
			conveyor motor.
		Capacitor, conveyor motor	Check for shorts or grounds. Replace capacitor as
			needed.
			WARNING: Capacitor has a stored charge, discharge
			before testing.
		Switch, conveyor reversing	Check continuity between switch terminals. Replace
			switch as needed.
		Oven control	If there is voltage supplied to the motor, and the motor,
			capacitor and reversing switch check good, replace the
			oven control.
	Conveyor motor runs,	NOTE: Display will indicate
	but there is no speed	“BELT JAM”
	display
		Oven control	Check for output voltage from oven control to hall effect
			sensor (sensor is located in the conveyor motor).
			Measure voltage at the motor connector, red wire and
			yellow wire. Voltage should be approx. 10VDC. If no
			voltage is present, trace wiring back to oven control. If
			there is no voltage output at the oven control, replace
			oven control.
		Conveyor motor	If there is voltage supplied to the hall effect sensor,
			check for a frequency output from the hall effect
			sensor. Measure frequency across the yellow and white
			wires in the motor connector. Frequency reading
