Quick facts about A2
Cooktops: Modernist induction models DTI30M977BB and DTI36M977BB
Display message: a malfunction of the fan motor
Cause listed in the manual: the DC motor is unable to operate because of the PCB, the wiring, or a blade on the motor that is blocked
What you can do about A2
For this code the manual gives no reset procedure and no owner check. It simply names three possible causes: the PCB, the wiring and a blocked blade. All three are inside the cooktop, so if A2 returns, turn the unit off at the controls and ask a technician to take a look.
Compare with other information codes
F0 is a board problem too, namely lost communication between the main PCB and the sub PCB.
UP concerns the voltage arriving at the cooktop rather than a component inside it.
C2 is a sensor message, this time for the IGBT sensor.
