When set to bake, after about 20 seconds the unit codes out with f-34. tech sheet only says: replace air switch, then replace cooling fan, then replace control. all 3 have been replaced, in that order, and its still giving f34. the tech sheet doesn’t give any other information about the code. Anyone have any suggestions?

It can be either the fan motors or the control board. I’m not sure if this is the one with the ability to see what the motor rpm is or not, but even though this feature is on some of the Thermadore ovens, we have found that it can still be either one. If its the motor, we have found sometimes it can have grease and or lint on it causing this problem. be ready for either component and tell your customer both can be a possibility. F34 is upper oven fan speed to slow you can check the fan speed throw disgnostics. hold the start and the dehydrate buttons down same time for 3 seconds you will go into diagnostic press timer #1 this will turn the fan speed on it should be 3200 rpm if it is less upper fan motor is bad . board send 18 volts to hall sensor on board.
