		the main fan motor) to neutral. If no voltage is
		present, trace wiring back to the main power switch.
		If voltage is present, check for 120VAC at wire #22
		(output of centrifugal switch) to neutral. If no voltage
		is present at #22, and the motor is running, replace
		the main fan motor.
	Hi-limit thermostat,	Terminals are normally closed. If open, reset
	oven cavity	thermostat and retest. If thermostat will not hold for
		maximum oven temperature, and oven is not
		exceeding temperature setting, check for proper
		location of capillary bulb in its spring holder. If the
		capillary checks okay, replace the hi-limit thermostat.
	Burner blower motor	Check for 120VAC supplied to burner blower motor
		at wire #13 to neutral. If no voltage is present, trace
		wiring back to the main power switch. If voltage is
		present, and the motor is not running, check for
		opens, shorts or grounds.
		WITH POWER OFF: Turn motor to check for locked
		rotor.
	Burner transformer	Check for 120VAC supplied to the primary of the
		burner transformer. If no voltage is present, trace
		wiring back to the oven cavity hi-limit thermostat. If
		voltage is present, check for 24VAC at transformer
		secondary. If there is primary voltage but no
		secondary voltage, replace burner transformer.
	Centrifugal switch of burner	Check for 24VAC at motor connector, wire #13 to
	blower motor	neutral. If voltage is not present, trace wiring back to
		transformer. If voltage is present, check for voltage at
		wire #14 to neutral. If no voltage is present at wire
		#14, and motor is running, replace burner blower
		motor.
	Ignition control	Check for 24VAC at ignition control terminals marked
		“24V”, if no voltage is present, trace wiring back to
		centrifugal switch. Check for 120VAC to ignition
		control at terminal “L1” to neutral. If no voltage is
		present, trace wiring back to main power switch.
		When 24VAC is supplied to the ignition control, the
		ignition control switches 120VAC to the hot surface
		igniter If 24VAC and 120VAC are supplied to ignition
		control, but there is no voltage at the hot surface
		igniter, replace the ignition control.
	Hot surface igniter	If 120VAC is present at hot surface igniter terminals,
		visually check to see that the igniter is heating
		(igniter may be viewed through the port in the end of
		burner tube). The igniter should glow bright red. If the
		igniter does not heat, replace the hot surface igniter.
	Ignition control	After 45 seconds of hot surface igniter pre-heat, the
		ignition control will switch 24VAC to the gas control
		valves. Check for 24VAC output from ignition control
		across terminals marked “valve” and “valve gnd”. If
		no voltage is present, replace ignition control.
	Gas control valves	When 24VAC is supplied to the gas control valves,
		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 the
		gas control valve is energized, but there is no gas
		pressure at the burner manifold, replace the gas
		control valves.
