GAS OVENS

MODEL 1600-000-A	NATURAL GAS	120 VAC.	60 HZ.	1 PHASE
MODEL 1601-000-A	LP GAS	120 VAC.	60 HZ.	1 PHASE

NOTE: When checking components on left side of oven, be sure to check for proper connections in power connector, (marked P.C. on schematic diagram) located inside motor cover.

SYMPTOM	POSSIBLE CAUSE	EVALUATION
Oven fan will not run	Incoming power	Check circuit breakers, reset if required. Check power plug to be
	supply	sure it is firmly in receptacle. Measure the incoming voltage. Call
		power co. if needed.
	Power switch	Check continuity between switch terminals. Replace switch as
		needed.
	Fuse, 10 Amp	Check, replace if necessary.
	Fuse holder	Check, replace if necessary.
	Fuse, 3 Amp	Check, replace if necessary.
	Fuse holder	Check, replace if necessary.
	Hi-limit thermostat(s),	Check for voltage on both sides of the switch. Terminals are
	control box	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
	Relay, oven power	Check for 120 VAC to the relay coil. If voltage is not present,
		Trace wiring back to the hi-limit thermostat. If voltage is present,
		check to insure contacts are closing. Check for 120 VAC supplied
		to terminal #2 of the relay. If voltage is not present at terminal #2,
		trace wiring back to the 10 Amp fuse. Replace relay as needed.
	Motor, main fan	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 circuit breakers, reset if required. Check power plug to be
		sure it is firmly in receptacle. Call power co. if needed.
	Power switch	Check continuity between switch terminals. Replace switch as
		needed.
	Fuse, 3 Amp	Check, replace if necessary.
	Fuse holder	Check, replace if necessary.
	Hi-limit thermostat(s),	Check for voltage on both sides of the switch. Terminals are
	control box	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.
	Cooling fan(s)	120 VAC should now be at the fan motor. If voltage is not
		present, trace wiring back to hi-limit thermostat. Check motor for
		opens, shorts or grounds. WITH POWER OFF: Check for locked
		rotor.
No automatic control box	Incoming power	Check circuit breakers, reset if required. Check power plug to be
cooling	supply	sure it is firmly in receptacle. Call power co. if required.
	Cooling fan	Check the cooling fan thermostat. (thermostat closes at 120°F
	thermostat(s)	°
		and opens at 100 F) With the cooling fan thermostat preheated,
		check for continuity. If switch is open, replace thermostat.
	Fuse, 3 Amp	Check, replace if necessary.
	Fuse holder	Check, replace if necessary.
	Hi-limit thermostat(s)	Check for voltage on both sides of switch. Terminals are
	control box	normally closed. If open, reset and test oven for proper
		operation. If thermostat will not hold, and control box
