SYMPTOM	POSSIBLE CAUSE		EVALUATION
Oven fan will not run	Incoming power supply		Check circuit breakers, reset if required. Check
			power plug to be sure it is firmly in receptacle.
			Measure incoming power, call power co. if needed.
	Fuse, 10 Amp		Check, replace if necessary.
	Fuse holder		Check, replace if necessary.
	Hi-limit thermostat,		Check for voltage on both sides of switch. Terminals
	control box		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°C), replace thermostat.
	Switch, main power		Check continuity between switch terminals. Replace
			switch as needed.
	Main fan motor		Check for 120VAC at motor. If no voltage is present,
			trace wiring back to main power switch.
			WITH POWER OFF: Check for opens, shorts or
			grounds. 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 circuit breakers, reset if required. Check
			power plug to be sure it is firmly in receptacle.
			Measure incoming power, call power co. if needed.
	Switch, main power		Check continuity between switch terminals. Replace
			switch as needed.
	Cooling fan		Check for 120VAC at cooling fan. If no voltage is
			present, trace wiring back to power switch. If voltage
			is present, and motor does not run, check for opens,
			shorts or grounds.
			WITH POWER OFF: Check for locked rotor.
No automatic control box	Incoming power supply		Check circuit breakers, reset if required. Check
cooling			power plug to be sure it is firmly in receptacle.
			Measure incoming power, call power co. 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 pre-heated, check for
			continuity. If switch is open, replace cooling fan
			thermostat.
	Cooling fan		Check for 120VAC at cooling fan. If no voltage is
			present, trace wiring back to cooling fan thermostat.
			If voltage is present, and motor does not run, check
			for opens, shorts or grounds.
			WITH POWER OFF: Check for locked rotor.
Oven will not heat	Gas supply		Check for adequate gas supply to oven.
	Manual gas shut off valve.		Check to see that the manual gas shut off valve is
			open. Also check flexible gas line connection for any
			damage.
	Main fan		If not operating, refer to “Oven fan will not run”.
	Centrifugal switch of main fan		Check for 120VAC at wire #5 (input to centrifugal
	motor		switch, located at 6-pin connector in raceway near
