	MODEL 1117-000-A		LP GAS		120 VAC	60 HZ	1 PHASE
	SYMPTOM	POSSIBLE CAUSE		EVALUATION
	Oven fan will not run	Incoming Power Supply		Check breakers, reset it required. Check power plug
				to be sure it is firmly in receptacle. Measure
				incoming power/call power company if needed.
		Fuse, 10 Amp		Check, replace if necessary.
		Fuse Holder		Check, replace if necessary.
		Hi Limit Thermostat-Control		Check for voltage on both sides of the switch.
		Box		Terminals are normally closed. If open, reset and
				test oven for proper operation. If thermostat will not
				hold and control box temperature is not exceeding
				140°F (60°), replace thermostat.
		Main Fan Switch		Check continuity between switch terminals.
		Main Fan Motor		Check for opens, shorts, or grounds. WITH POWER
				OFF turn fan blade to check for locked rotor.
		Capacitor		Check for shorts or grounds.
				WARNING: Capacitor has a stored charge,
				discharge before testing.
	No control box cooling	Incoming Power		Check main circuit breakers, reset if required, call
				power company if needed.
		Main Fan Switch		Check continuity between switch terminals
		Cooling Fan		120 VAC should now be at the fan motor. If voltage
				is present, check motors for shorts or opens. WITH
				POWER OFF: Check for locked rotor.
	No automatic control	Incoming Power Supply		Check circuit breakers,
	box cooling			reset if required. Call the power company if needed.
		Cooling Fan Thermostat		Check the cooling fan thermostat. (Thermostat
				closes at 120°F and opens at 100°F). With the
				cooling fan thermostat preheated, check for
				continuity. If switch is open, replace.
		Cooling Fan		120 VAC should be at the motor. If voltage is
				present, check motor for shorts, opens, or grounds.
				WITH POWER OFF: check for locked rotor.
	Oven will not heat	Gas Supply		Check for adequate gas supply and closed manual
				gas shut offs. Also, check flexible gas line
				connection.
		Main Fan		If not operating, refer to "Oven fan will not run".
		High Limit Oven Cavity		Terminals are normally closed. If
		Thermostat		open, push in reset button and retest. If thermostat
				will not hold for maximum oven temperature, and
				oven is not exceeding temperature dial setting,
				check for proper location of capillary bulb in its
				spring holder. If above checks okay, replace hi-limit
				thermostat.
		Centrifugal Switch		Check for 120 VAC at lead #9
		of Main Fan Motor		(located at 6 pin connector in raceway near the main
				fan motor) to neutral. If no voltage is present, and
				motor is running, replace motor.
