Lincoln 1162-080-A Replace relay as needed, Main fan runs after, Oven start relay, Oven fan relay

		Replace relay as needed.
Main fan runs after	Oven start relay	Contacts should open when main power switch is
20 minute cool down		turned off. Replace relay as needed.
	20 Minute time delay	120VAC at terminal #2 should discontinue approx.
		20 minutes after main power is switched off. If the
		oven start relay contacts are open, and the
		voltage continues at terminal #2 of the 20 minute
		timer, for more than 20 minutes, replace the 20
		minute time delay.
	Oven fan relay	Check to insure that the relay contacts are
		opening after the relay coil is de-energized.
		Replace relay as needed.
	20 Minute time delay	NOTE: On/ off operation of the main power switch
		will set the timer to 20 minutes. If the timer is
		accidentally reset, turn off the main circuit breaker
		for 15 seconds to cancel.
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 supply voltage 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 supply voltage 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	Main fan motor	Check for main fan operation. If it is not operating,
		refer to “Oven fan will not run”.
	Air pressure switch	This normally open switch should close when the
		main fan is activated. Refer to the “Removal and
		installation” section for proper adjustment.
		Replace as needed.
	Control transformer	Check for 120VAC supply to the primary of the
		control transformer. If no voltage is present, trace
		wiring back to the main power switch. If voltage is
		present, check for 24VAC at the transformer
		secondary. If there is primary voltage, but no
		secondary voltage, replace the control
		transformer.
	Oven control	Check for 24VAC supply to control. If no voltage is
		present, trace wiring back to control transformer. If
		24VAC is present, check for a read-out on the
		display. If there is 24VAC supplied, but there is no
		read-out on the control display, replace the oven
		control.
