TROUBLESHOOTING GUIDE

A. UNIT WILL NOT HEAT, CONVEYOR BELT WILL NOT MOVE.
1) Be sure the main circuit breaker is switched to the ON position.
2) Check to see if the toaster is plugged in and all controls are turned to the ON position.
B. UNIT HAS HEAT ONLY ON ONE SIDE, CONVEYOR BELT TURNS FREELY.
1) Call the Star Service Help Desk at (314) 678-6303, as heating element may need replacing.
C. CONVEYOR WILL NOT TURN, UNIT HEATS PROPERLY.
To check for mechanical binding:
1) DISCONNECT UNIT FROM POWER SOURCE.
2) Remove 2 screws holding enclosure to the bottom of the unit.
3) Set unit on the legs and remove 4 screws on the back of the toaster.
4) Slide the enclosure off the unit and remove the back panel.
5) Loosen the four screws that hold the drive motor in place.
6) Slide the motor up allowing the drive chain to be removed from the sprockets.
7) Move the conveyor belt by hand to check for mechanical binding. If conveyor moves freely,
call the Star Service Help Desk at (314) 678-6303, as the drive motor and/or speed control may
need replacing.
8) Replace the enclosure by sliding it forward towards the front of the unit.
The front edge of the enclosure will slide beneath the toaster front.
D. HEAT LIMIT SWITCH (RESET)
Your Holman conveyor toaster is equipped with an automatically activated heat limit switch that
interrupts the heater tube connections if the ambient temperature in the control box exceeds
190°F (88C). This switch can be reset manually by pushing the red button under the toaster as
shown in the Toaster Components Illustration on Page 5 & 8.
1) DISCONNECT UNIT FROM POWER SOURCE.
2) Check to see if air intake area in the bottom center of the control box cover is free of dust,
grease or other obstructions.
3) Check if crumb tray is in place. NEVER OPERATE UNIT WITHOUT CRUMB TRAY IN PLACE
AS THIS CAUSES OVERHEATING IN THE CONTROL BOX.
call the Star Service Help Desk at (314) 678-6303 or email; service@star-mfg.com for
assistance, or contact an authorized service agent near you.
E. CONVEYOR TURNS AT ONE SPEED REGARDLESS OF SPEED
CONTROL SETTING.
1) Call the Star Service Help Desk at (314) 678-6303 or email; service@star-mfg.com, as speed
control should be replaced, or contact an authorized service agent near you.
F. PRODUCT STICKING TO CONVEYOR OR SLIDE
Your Holman conveyor toaster is designed to toast product that is at current room temperature.
DO NOT attempt to put frozen, refrigerated, or any butter or a butter substitute material in the
toaster. Doing so may cause it to come out doughy or very moist, as well as possibly sticking to
parts of the unit.
1) Follow the cleaning procedures listed on page 10.
