Lincoln 1633-000-EA Gas pressure switch, Check for supply voltage to neutral, Hi-limitthermostat

Fuse holder	Check, replace if necessary.
Gas pressure switch	Check for supply voltage to neutral
(internal to gas valve)	on both sides of switch. If voltage is
	present on one side of switch only,
	check the following. Check for proper
	gas pressure supply to gas valve.(Marked
	on oven spec. plate.) Check for proper
	adjustment of gas pressure switch.
	should be set at 10 Nat., 27 for L.P.
or 4.5 for town gas. Check gas filter in
	gas valve for blockage or damage. (See
	Adjustment section for location.)
	If the above checks OK, but switch is
	still not closed replace gas valve.
Oven air pressure switch	Check for supply voltage on both sides
	of switch. If voltage is present on one
	side only, check for air tube blockage.
	Adjust air pressure switch. If the above
	fails, replace air pressure switch.
Hi-limit thermostat	Terminals are normally closed. If open,
	reset and test oven for proper operation.
	If thermostat will not hold for maximum
	oven temperature, and oven is not
	exceeding maximum temperature dial
	setting, check for proper location of
	capillary bulb in its spring holder.
	If above checks OK, replace hi-limit.
Ignition control	Check for supply voltage to ignition
	control at terminal #1 and neutral.
	If voltage is not present, trace wiring
	back to hi-limit thermostat. Check for
	supply voltage at terminal #6 to neutral.
	If no voltage is present, wait 30 seconds
	and check reset button. If above fails,
	replace ignition control.
Burner reset switch	Switch is normally open. Check to see
	that the switch closes when reset button
	is pushed. Replace as needed.
Burner blower motor	Check for supply voltage to burner
	blower motor.
	WITH POWER OFF: Turn blower
	wheel to check for locked rotor. If
	supply voltage is present and motor does
	not run, replace motor.
Burner blower motor	Check for supply voltage switching to
Air pressure switch	terminal N. O. as the air pressure switch
	closes. Check for air tube blockage or
	misalignment, adjust air pressure switch.
	If the above fails, replace air pressure
	switch.
Spark generator	After a pre-purge time of 30 to 60
	seconds after blower motor starts,
	check for supply voltage to spark
	generator. If voltage is not present,
	Check reset button located on rear of
	control box. If voltage is still not
	present, replace ignition control.
	If voltage is present, visually check
	for spark at igniter head.
Igniter/sensor assembly	Check for visible damage to igniter/
	sensor assembly. If there is no visible
	damage to the components, and no spark,
