Matt May 27, 2020 for Model Number C302BS/01 Hi, I get error code F64 and the oven shuts off after about 1 minute of pre-heating. Happens with both top and bottom ovens. Some reading online indicates I should be looking to replace the lower fan motor. Does this sound right, and can you point me to the correct part? I see several options when searching for the fan motor. Thanks, -Matt
1 Answer Matt, the lower blower fan is part number 00440665. However, it would be recommended that the blower motor (located in the back between the upper and lower ovens) is inspected for any obstructions, as well as the vent below the lower oven, in the fan blades as well as identifying if the fan rotates and pushes air. If the fan does push out a decent airflow, it may be possible that there is a dust build up along the air switch located just under the lower oven that is preventing it from registering air flow.

Paul December 27, 2019 for Model Number SEC301BS This is a Thermador wall oven, single unit. Same story as others. Repeated F34 shut downs, the third or fourth try usually works. Fan always runs. When I inspect through the bottom vent, there are no sail switches in there, as depicted in all of the literature for the double oven. Does the single unit detect fan speed with something on the fan itself? Can cleaning the fan area help? How likely is it that the problem is the relay board or control board reading signals incorrectly?
1 Answer Paul, cleaning the fan area and ensuring that the ventilation is clear of anything that could prevent airflow can certainly help. The fan motor can be tested from the relay board at connection P6 pin 5 (red probe of meter) to pin 3 (black probe of meter) for 18VDC and then from pin 4 to ground chassis for 2VAC. If the voltages read good, then the issue is the relay board 00427198. If there is 18VDC but not the 2VAC reading, then the fan motor 00440604 would need to be changed. If there is not 18VDC, then the relay board is bad and is not sending proper voltage to the fan motor. Read More...
J October 14, 2018 for Model Number Thermador C271 Approximately 3 months ago my Thermador c271 began displaying intermittent F34 errors. Up until the past week I was able to get the oven to start with a few attempts of starting up the oven, but recently no amount of attempts will prevent the oven from shutting off. I initially thought it might be the fan switch, but upon checking I discovered there were no fan switches. Im happy to repair this myself but don't want to buy an unneeded part ... is this behavior more likely to happen with a faulty blower or a faulty control panel? Thank you!
1 Answer J, This issue would most likely be a cooling fan issue which is part number 00444098. Read More...
John Zz March 01, 2018 for Model Number HBL5450UC/06 Getting BOSCH error code e118, resetting breaker makes it functional, but then fairly routinely keeping getting error. Is it rolling fan and / or control board? Fan looks gunked up a bit and brownish when looking at it through grate at top front with flashlight (have not removed oven).
1 Answer John, This issue will most likely be caused by a faulty cooling fan which would be what the error code represents but check the wiring from the fan to the control to make sure that it is not damaged. Read More...
Bill K November 22, 2017 for Model Number SEC301BB/03 Thermador Single Wall Oven Error Code F 34. Through the display I'm able to see RPMs bouncing between 3000 and 3060. Oven shuts down while heating up with reading at 3060 RPM. Descriptions of F34 code all assume double oven and say code refers to top oven. Also refer to a 'sail switch' in the air stream somewhere. All I see is the 'hampster cage' blower on top with what appears to be a sensor on the right side when viewed from the front. I'm tempted to order the replacement blower but, at $150+, I feel like I'm guessing. Any advice? Am I missing something? Thanks.
1 Answer Bill, It would be recommended to check the sail switch and if it checks ok then the issue will be a faulty blower assembly. Read More...
Joe October 10, 2017 for Model Number C302 I have a 30" Thermador double oven. It starts to beep continuously and the control panel goes blank after running for a while (during baking) and or turned off and sitting. I read that it could be the gaskets leaking. I replaced the gaskets and its helped a lot, but it still does it every once in a while. Could the upper cooling fan be bad with no error showing? I am happy to replace it, but was wondering if the oven would "know" and indicate if the fan was dead.
1 Answer Joe, The cooling fan will most likely be the cause for the unit to have the symptoms you show. Read More...
Paul April 05, 2017 for Model Number Thermador Mod# C302UB I'm getting an error code of F34 which I understand is an Upper Fan Not Coolong.The fan is running but I believe there is a temp sensor in this assembly that might be malfunctioning. I'm looking for the part number. Thank you.
1 Answer Paul, The error code "F34" means "The (upper) oven cooling fan air switch not detected". The problem can be a bad air switch, a bad blower fan motor, a clogged vent line or a broken wires. The air switch and fan motor can be tested for continuity. There is a RPM sensor on the fan motor, but there is no "temperature" sensor. Read More...
Mark December 12, 2016 for Model Number Thermador sc272tb I need to replace blower fan, the one in the middle of oven, not on top, its part number is 14-38-515(fasco transflo blower) is it the same as the one of the top of oven
1 Answer Mark, The upper and lower fan motors are different and the part number for the lower would be 00431492 and the upper is 00444098. Unfortunately the lower motor has been discontinued by the manufacturer with no suitable replacement. Read More...
Dave Wilmer February 10, 2015 for Model Number CM302UW How hard is it to replace the top cooling fan on this wall mounted double oven? I believe it is the squirrel cage fan that is making a squealing noise when I turn on either the upper or lower oven.
1 Answer Dave, In order to remove the fan you will need to pull the unit out from the wall and remove the upper cover of the unit. At this point you will be able to access the fan assembly in order to replace it. Read More...
