Lincoln 1117-000-A Burner Blower Motor, Visually check to see if motor is running. If not

	Burner Blower Motor	Visually check to see if motor is running. If not,
		check for 120 VAC to motor at motor connector (wire
		#5 and #22). If voltage is not present, trace wiring
		back to fan switch. If voltage is present and motor is
		not running, check for opens, shorts, or grounds.
		Also, WITH POWER OFF: check for locked rotor.
	Transformer, Burner	Primary is 120 VAC with 24 VAC secondary. If 120
		VAC is not present, trace wiring back to Main Fan
		Centrifugal Switch. If 120 VAC is present, check for
		24 VAC at secondary of transformer. If no voltage is
		present, replace transformer.
	Centrifugal Switch of Burner	Check of 120 VAC at motor connector, on wire #13
	Blower Motor	to neutral. If voltage is not present, trace wiring back
		to transformer. If voltage is not present and motor is
		running, replace the burner blower motor.
	Ignition Control	24 volts should be present at 24 volt terminals. If not
		present, trace wiring back to centrifugal switch.
		When 24 VAC is supplied, the control switches 120
		VAC from L1 and L2 to the hot surface ignitor. if 120
		VAC is not present at L1 and L2, trace wiring
		back to fan switch. If 24 VAC and 120 VAC are
		present and 120 VAC is not across the hot surface
		ignitor terminals, replace the ignition control.
	Hot Surface Ignitor	If 120 VAC is present at hot surface ignitor terminals,
		visually check to see that the ignitor is heating.
		(Ignitor may be viewed through the port glass in end
		of burner tube.) The ignitor should glow bright red.
		If the ignitor does not heat, replace the ignitor.
	Ignition Control	After 45 seconds of hot surface ignitor pre-heat, the
		ignition control will switch 24 VAC to the gas control
		valves. Check for 24 VAC output from ignition
		control, across terminals marked "valve" and "valve
		ground". If no voltage is present, replace ignition
		control.
	Gas Control Valves	When 24 VAC is supplied to the gas control valve,
		the valve should open. Check for gas pressure at
		the manifold tap located just before the burner. If
		there is no pressure, check the incoming gas supply
		to be sure all manual valves are open and flexible
		gas hose is properly connected. If gas is present
		and coils of gas valve are energized, the gas valve is
		probably defective.
Flame will not stay lit	Hot Surface Ignitor	Six seconds after the gas valve opens, ignition must
		occur. if flame is not detected, the ignition control
		will shut off and lock out. To reset the ignition
		control, turn off the burner switch for 45 seconds,
		then turn on the burner switch to retry ignition. The
		ignition control requires a minimum of 0.8 D.C.
		microamps. To check flame sensing operation,
		connect a digital multimeter (capable of measuring
		D.C. micro-amps) between the "ground" terminal on
		ignition control and the ground lead.
		NOTE: This is a current measurement and the
		meter must be connected in series. If these
		readings are not achieved, replace the hot surface
		ignitor.
		NOTE: The D.C. micro amp test must be conducted
		with the oven in low flame (bypass) operation. Turn
		the temperature control to the lowest setting.
