	Cooling Fans	120 VAC should now be at these fan
		motors. If voltage is present,
		check motors for shorts or opens.
		WITH POWER OFF: Check for locked rotor.
Cooling fans continue	Cooling Fan Thermostat	Thermostat is normally open and may to run after
20 minute		have closed if control box temperature cool down
		is 120°F or above.
Oven will not heat	Gas Supply	Check for adequate gas supply and
		manual gas shut off valve is open.
		Also, check flexible gas line connection.
	Main Fan	If not operating, refer to “Oven Fan

		across these terminals.
	Burner Switch	Check for supply voltage on both sides of
		switch. If switch is closed and voltage
		present on one side only, replace switch.
	Gas Pressure Switch	This switch is located inside the gas
		valve and should close when gas
		pressure is present.
		WITH POWER OFF: remove 3 prong plug
		(on gas valve) and measure continuity between
		terminals 2 and 3.
		NOTE: Remove insulation pad below plug to
		read numbers. If no continuity, check the
		following:
		Proper gas pressure supply to gas valve as
		marked on the oven specification plate.
		Check for proper adjustment of gas
