C. HEAT LIMIT SWITCH
Your conveyor oven is equipped with an automatically 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 as shown.
THE HEAT 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 air intake area (openings in bottom center of control box) is free of dust, grease or
other obstructions.
3) Check to see if crumb trays (heat reflectors) are in place.
NEVER OPERATE UNIT WITHOUT CRUMB TRAYS IN POSITION AS THIS CAUSES OVERHEATING IN
THE CONTROL BOX.
