TROUBLESHOOTING(continued)
Problem Possible Cause Corrective Action
Product is over-toasted
or platen heat is too high
or drop time is too slow.
(continued).
Spring tensioner assy(s). or
tensioner bent or missing.
Replace spring tensioner assy(s). (29, page 20)
or tensioners (4, page 24) if damaged or loose.
Replace slide rails (40, page 24) if worn or missing.
Bun adjustment controls set
incorrectly.
Measure bun thickness and set bun adjustment con-
trols correctly (page 9).
Product is under toasted
or platen heat is too low
or drop time is too fast.
Not enough voltage, defec-
tive power cord, defective
rocker switch.
Confirm platen temperature reading with a pyrometer
or other temperature source.
Check receptacle for correct voltage. See
Specifications (page 5).
With unit plugged in and rocker switch on, check for
correct voltage into rocker switch. If low or zero volt-
age, replace power cord. If voltage is correct, check
for correct voltage out of rocker switch. If low or no
voltage, replace rocker switch.
Wiring problem. Check all electrical connections for burns, discolor-
ation or arcing. Replace all connections or compo-
nents with damaged terminals. Replace all damaged
wiring with the same (or higher) rated wire.
Platen inoperative. To check platen:
Use an Ohm meter to test resistance of the platen
heater (disconnect 1 wire to isolate heater). Correct
cold resistance for heating element of platen are as
follows:
120 Volts, 1750 Watts - 7.8 Ohms
208 Volts, 2550 Watts - 16.2 Ohms
230 Volts, 1900 Watts - 26.5 OhmsVCT-20 only. The
auxiliary heaters are 144.2 Ohms at 208V/300 Watts.
Conveyor drive motor inop-
erative or incorrect conveyor
motor installed in toaster.
To check drive motor:
1. Measure resistance of motor coil. Replace motor
if coil measures either open circuit or zero resis-
tance.
2. Mark the drive motor sprocket and count the turns
per minute. Correct drive motor speed is nine (9)
turns per minute for VCT-20; three (3) turns per
minute for VCT-25; one (1) turn per minute for
VCT-50.
Product is getting stuck
or conveyor belts stop
when product is toasting.
Bun adjustment controls set
incorrectly.
Measure bun thickness and set bun adjustment con-
trols correctly (page 9).
Conveyor release sheet not
clean or missing.
Clean respective items. Refer to Maintenance
Schedule (page 10).
