Rational SCC 202 service 34-6
34-6 is a service code associated with both the upper and lower oven fans not operating. Check the fan motors. there is a green LED. they should be on steady. If they are blinking, watch and count how many times it blinks before starting over. that is the error code associated with the fan motor. If there is no LED lit, then the fan power supply has failed. The fan failure is a hexadecimal code. "2" is the master fan failure, "4" is the slave fan. "6" is both fans. data to and from the fans is via the I/O PCB. There is a data cable from the operator pcb to the I/O PCB, then on to the fans. The problem can lie anywhere. Fans, PCB's, or data connections.
