Lincoln 3262-2, 3270-2 Check for supply voltage to conveyor control at, switch as needed, proceed

		switch as needed.
	Control, conveyor	Check for supply voltage to conveyor control at
		terminals #1 (AC) and #2 (AC). If no voltage is present,
		trace wiring back to conveyor switch. If AC voltage is
		present, check for DC voltage output at terminals #3
		(A-) and #4 (A+). If there is AC voltage in, but no DC
		voltage out of the conveyor control. Replace the
		conveyor control. If there is D.C. voltage output,
		proceed.
	Fuse, 2 Amp	Check, replace if necessary.
	Fuse holder	Check for D.C. voltage supplied to fuse holder. If no
		voltage is present, trace wiring back to conveyor
		control. Check fuse holder, replace if necessary.
	Switch, conveyor reversing	Check for D.C. voltage supplied to the reversing switch.
		If no voltage is present, trace wiring back to the fuse
		holder. Check continuity between switch terminals.
		Replace switch as needed.
	Conveyor motor	Check for D.C. voltage to the conveyor motor. If no
		voltage is present, trace wiring back to the reversing
		switch. If voltage is present and the motor will not run,
		check the motor windings for opens or shorts. Check
		motor brushes for excessive wear. Replace motor
		brushes as needed.
		If any of the above fails, replace conveyor motor.
	Conveyor	Check for any mechanical problems in the conveyor
		assembly. Check for damaged or torn belting. Check
		conveyor shaft bearings for damage or excessive wear.
		Repair or replace conveyor components as needed.
Conveyor speed varying or	Power supply	Check for a steady supply voltage to the conveyor
intermittent		control. If voltage is not steady, trace back to power
		supply.
	Control, conveyor	Check for a steady DC voltage output at terminals A+
		and A-. If voltage is not steady, proceed. Check for
		5 VDC output from the conveyor control at terminals
		+5V(red) and COM (black). If there is no voltage output,
		replace the conveyor control. If there is DC output,
		proceed.
	Motor, conveyor	Check conveyor motor and gearbox for any visible
		damage. If there is apparent damage, repair or replace
		conveyor motor. Check motor brushes for excessive or
		abnormal wear. Replace motor brushes as needed.
	Hall effect sensor/magnet	Check to be sure that the Hall effect sensor and
		magnet are mounted on the motor. Check for any
		visible damage to the Hall effect sensor and magnet. If
		there is visible damage, repair or replace as needed. If
		there is no visible damage, check for a frequency
		output from the hall effect sensor at terminals SIG
		(white) and COM (black).
		Readings should be as follows:
		2:15 cook time	56 Hz. approx.
		5:00	25 Hz. approx.
		10:00	13 Hz. approx.
		16:00	8 Hz. approx.
		If these readings are not achieved, replace the Hall
		effect sensor/magnet
