		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.
Flame will not stay lit	Hot surface igniter	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 power switch for 45
		seconds, then turn the switch on to re-try ignition.
		The ignition control requires a minimum of 0.8 DC
		microamps to prove flame. To check flame
		sensing operation, connect a digital multimeter
		(capable of measuring DC microamps) 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 hot
		surface igniter.
		NOTE: The DC microamp test must be conducted
		with the oven in low flame (bypass) operation. Set
		the temperature control to the lowest setting.
	Power supply	If there is sufficient microamp current, but the
		flame will not stay lit, check for proper polarity of
		the 120VAC power supply.
	Ignition control	If there is sufficient microamp current, and the
		120VAC polarity is correct, but the flame will not
		stay lit, replace the ignition control.
		NOTE: Check for proper ground connection on
		ignition control.
	NOTE: Flame should be on at
	this time
Low flame is on,	Control transformer	Check for 120VAC supply to the primary of the
but no main flame		control transformer. If no voltage is present, trace
		wiring back to the main power switch. If voltage is
		present, check for 24VAC at the transformer
		secondary. If there is primary voltage, but no
		secondary voltage, replace the control
		transformer.
	Oven control	Check for 24VAC supply to control. If no voltage is
		present, trace wiring back to control transformer. If
		24VAC is present, check for a read-out on the
		display. If there is 24VAC supplied, but there is no
		read-out on the control display, replace the oven
		control.
		If there is a read-out on the control, set the control
		to maximum temperature (see installation
		operations manual for temperature adjustment).
		With the control set at maximum temperature,
		check for 120VAC at the temperature regulation
		valve. If there is voltage at the temperature
		regulation valve, proceed to “Temperature
		regulation valve” for next check. If there is no
		voltage at the temperature regulation valve, trace
		wiring back to the oven control. If there is no
