HBL/HBN 7 FAULT CODE DEFINITIONS
AND BASIC TROUBLESHOOTING
HINT: After a latch fault, due to any hardware problem, the control can disable one cavity and prevent the opposite one to work in self-clean. First remove the fault cause, then after a latch auto- test at power-up, if either cavities or clean mode are still inhibited, press and hold the [Start] key for one minute until F121 is displayed, then press [Cancel].
Generally, to cancel a persistent fault, press and hold the [Start] key for one minute until F121 is displayed, then press [Cancel].
HINT: Sometimes at power-up, the F155 fault code is displayed. Press [Cancel] key to reset the alarm. If F155 is displayed again when starting a cooking mode, it means that parameters are corrupted in the Display Board and the EEPROM needs to be re-programmed. Otherwise, the oven will work correctly.
