I have a Rational SCC 101LP oven and when the power goes down and gets restored the error code ESTB appears and will not allow the oven to operate. How do I clear this once and get back to cooking?

This could be due to various reasons such as power fluctuations, overheating, software glitches, or hardware malfunctions. Have you tried checking the power source, ensuring proper ventilation

Examine the oven's control panel to identify any error codes or displayed indicators.

check the transformer. It should tell you how many volts you are supposed to get. A SCC WE62G machine provides 18v and 240v from the transformer.

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.
