Lincoln Series 1000, Series 1200 specs

	Spark Generator	After a pre-purge time of 30 to 60 seconds after
		blower motor starts, check for 220 VAC to spark
		generator. If voltage is not present, check reset
		button on ignition control. If voltage is present,
		visually check for spark at ignitor head.
	Ignitor/Sensor Assembly	Check for visible damage to ignitor/sensor
		assembly. If there is no visible damage to the
		components, and no spark, replace the spark
		generator. If there is visible damage to the ignitor
		sensor assembly, replace. Also check for frayed or
		damaged wire in burner tube.
	Gas Valve	Check for 220 VAC supply to gas valve. If no
		voltage present, check reset button on ignition
		control, check all connections for tightness. If there
		is no voltage at gas valve, replace ignition control.
		If there is voltage present, check for gas pressure
		at gas pressure tap located in gas piping. If there is
		no gas pressure, replace gas valve.
No Pilot		If the ignition control is energized, and the gas
		valve and ignitor circuits are energized, visually
		check for pilot flame. This may be done by opening
		the small inspection door on the end of the burner,
		or by opening the main oven door and looking
		under the lower finger housings on the right side of
		the oven. If no pilot flame is visible, check the
		following.
	Pilot Tube	Check for gas pressure at pilot tube. Disconnect
		pilot tube at burner and connect manometer to pilot
		tube. If no gas pressure is present, check for
		blockage in pilot tube. If these are clear, and there
		is gas supplied to the oven, replace the gas valve.
	Pilot Orifice	If there is gas pressure at the pilot tube, check the
		pilot orifice for obstructions. Replace as needed.
	Burner Ignitor	Check the burner ignitor head for any obstructions,
		also check for frayed or broken wire, any type of
		damage to spark gap (.100 in 2.5 mm).If there is
		visible damage, replace ignitor assembly.
Pilot flame, but burner	Flame Sensor	(There should be a visible pilot flame at this time).
will not stay ignited		To check for flame sensor operation, connect a
		digital multimeter. (Capable of measuring D.C.
		microamperes) between the flame sensor wire and
		the ignition control. NOTE: This is current
		measurement and the meter must be connected in
		series. Proper current readings should be
		Honeywell 2-4 micro amp D.C., Landis & Gyr. 3
		micro amp D.C. If these readings are not achieved,
		replace ignitor/sensor assembly. Also check for any
		type of damage to flame sensor wire and
		connections.
	Ignition Control	If there is sufficient flame sensor current, but the
		burner will not remain ignited, check reset buttonon
		ignition control.
Indicator light is on but	Gas Control Relay	Check for 220 VAC to relay coil. If no voltage is
no main flame, (Model		present, trace wiring back to ignition control. If
1046-1047)		voltage is present, check to insure contacts are
		closing.
