Fault Code Descriptions

Fault codes are logged in a fault counter (page

16)for troubleshooting. Upon completing the service call and restoring successful operation of the oven, the technician should clear all faults (see page 20).

F1: Blower Failure

This fault is displayed if for three consecutive times the control board does not receive the “status OK” signal from the BMSC.

The fault is cleared from the display if the blowers successfully restart upon starting a cook cycle or in TEST MODE.

F2: Low Temp During Cook

The oven will emit a beeping noise and display this fault if the cook cavity temperature falls 25°F (14°C) below the current cooking profile’s set temperature, and the fault will be logged in the fault counter.

The fault is cleared from the fault display if the cook cavity temperature returning to within 25°F (14°C) of the set cooking temperature during cooking or in TEST MODE.

F3: Flameout

This fault is displayed if the flame fails to light three consecutive times at startup, or once the oven reaches the cooking temperature, the flame goes out and fails to re-light three consecutive times.

The fault is cleared from the display if the flame succeeds to light when the user re-selects the

cooking profile.

F4: Emergency Stop

This fault is displayed when the emergency stop key is pressed.

This fault acts as a counter that logs how many times the emergency stop key (page 9) has been pressed.

The fault is cleared from the display once the oven is restarted.

F5: CC Over Temp

This fault is displayed if the cook cavity’s tem- perature reaches or exceeds 625°F (329.4°C).

The fault is cleared from the display once the oven is restarted and the temperature recedes below 625°F (329.4°C).

F6: EC Over Temp

This fault is displayed if the equipment cham- ber reaches 149°F (65°C); however, the oven will not shut down and the fault will not be logged in the fault count log unless the equip- ment chamber reaches 158°F (70°C).

The fault is cleared from the display when the equipment chamber temperature falls below 149°F (65°C).

F7: RTD Failure

This fault is displayed if the RTD circuit is open, shorted, reads above 645°F (340.5°C), or reads below -40°F (-40°C).

The fault is cleared from the display if the RTD circuit is closed, or the temperature reads within 645°F (340.5°C) and 40°F (-40°C)
