Lincoln 3270-2, 3262, 3240-2 specification

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 motor	Check for main fan operation. If it is not operating, refer
		to “Oven fan will not run”.
	Relay, main fan	Check for supply voltage to relay terminal #13. If
		voltage is not present, trace wiring back to power
		supply. If voltage is present, check for supply voltage at
		terminal #14. If there is no voltage at terminal #14, and
		the relay is energized, replace the main fan relay.
	Fuse, 2 Amp, control (F8)	Check, replace if necessary.

	Fuse holder	Check, replace if necessary.

	Switch, oven fan	Check for supply voltage to the switch, if no voltage is
		present, trace wiring back to the main fan relay. Check
		continuity between switch terminals. Replace switch as
		needed.
	Switch, burner	Check for supply voltage to the switch, if no voltage is
		present, trace wiring back to the oven fan switch.
		Check continuity between switch terminals. Replace
		switch as needed.
	Air pressure switch	Check for supply voltage to the air pressure switch. If
		no voltage is present, trace wiring back to burner
		switch. This normally open switch should close when
		the main fan is activated. Check air switch tube for
		blockage or any obstructions, repair as needed. Refer
		to the “Removal and installation” section for proper
		adjustment of air pressure switch. Replace air pressure
		switch as needed.
	Thermostat, hi-limit	Terminals are normally closed. If open, reset and test
		oven for proper operation. If thermostat will not hold for
		maximum oven temperature, and oven is not exceeding
		temperature control setting, check for proper location of
		capillary tube in the oven cavity. If above checks okay,
		replace hi-limit thermostat.
	Burner control	Check for supply voltage to the burner control at
		terminals #1 and #3. If no voltage is present, trace
		wiring back to the hi-limit thermostat. If voltage is
		present, check for supply voltage at pins #8 and #3
		(burner blower motor). If voltage is not present, replace
		burner control. If voltage is present, proceed.
	Motor, burner blower	Check for supply voltage to the burner blower motor. If
		no voltage is present, trace wiring back to the burner
		control. If voltage is present, and the motor is not
		turning, check for opens, shorts or grounds.
		WITH POWER OFF: Check for locked rotor.
		Replace burner blower motor as needed.
	Air pressure switch	Check for supply voltage at the COM terminal on the air
	(burner motor)	pressure switch. If no voltage is present, trace wiring
		back to burner control. If voltage is present, check for
		supply voltage switching to the NO terminal on the air
		pressure switch. If the burner blower motor is running,
		but voltage is not switching to the NO terminal of the air
		pressure switch, check air switch tube for blockage or
		any obstructions, repair as needed. Refer to the
		“Removal and installation” section for proper
		adjustment of air pressure switch. Replace air pressure
		switch as needed.
