Page 12: Troubleshooting Guide
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 and there is power to the outlet. 2) Check to see if the toaster is plugged in and all controls are turned to the ON position. 3) Be sure the Hi-Limit Reset Button is pushed in. 4) Call the Star Service Help Desk at 1-800-807-9054.

UNIT WILL NOT HEAT, CONVEYOR TURNS PROPERLY. 1) Check to see if the heat controls have been turned to the maximum setting. 2) Press the Hi-Limit Reset Button located on the end under the conveyor belt. If this reactivates the heater tubes, see Hi-Limit Reset Section below. 3) Call the Star Service Help Desk at 1-800-807-9054. C. HI-LIMIT (HEAT) RESET. Your Holman conveyor toaster is equipped with an automatic activated temperature limit switch which interrupts the heater tube connections if the air temperature in the control box exceeds 190°F (88°C) This limit switch can be reset manually by pushing the button in the center of the switch which is located on the right side under the conveyor belt. See Oven Components on Page 7 for location. Unit will not reset until internal temperature has fallen below 190°F (88°C). NOTE: THE HI-LIMIT SWITCH CAN BE ACTIVATED IF THERE IS NOT A PROPER AMOUNT OF AIR FLOW BEING GENERATED BY THE COOLING FAN. IF THIS OCCURS: 1) DISCONNECT UNIT FROM POWER SOURCE. 2) Check to see if the air intake area is free of dust, grease or other obstructions. 3) Check to see if crumb trays (heat reflectors) are in place. If the Hi-Limit Switch can not be reset, call the Star Service Help Desk at 1-800-807-9054. NEVER OPERATE UNIT WITHOUT CRUMB TRAYS IN POSITION AS THIS CAUSES OVERHEATING IN THE CONTROL BOX.
