Top 20 Thermador C301U Electric Single Oven Questions & Answers

The F13 fault code on this type of range indicates that the EEPROM (Electrically Erasable Programmable Read-Only Memory) on the control board is bad. This can be caused by a power surge or glitch through the electrical lines. You can try to reset the control board by completely unplugging the range (or shutting off the breaker) for 5 minutes. If the error code returns after plugging the range back in, then the control board for the range will need to be replaced.

Check if the internal ventilation fan is running. It is intended to cool down the oven exterior. Some units made 2004-2007 can overheat during self-cleaning.

For most codes, Touch OFF or turn power off at the circuit breaker, wait 3 minutes and turn it back on.

fan/air flow issue. call a qualified technician.

fan/air flow issue.

oven over temperature. replace oven sensor, replace relay board if repeats.

could be a relay board problem. may be a bad solder connection on it. Inspect all with a good magnifier. resolder as needed.

overheat situation. check oven sensor and soldered pin points for sensor wires at relay board. Resolder if needed.

F33 ( upper oven over temperature while cooking ) Check sensor should read 1080 ohms at room temp. You will need to replace the oven temperature sensor. There is no quick fix for this problem to get you up and running on this Thanksgiving day, sorry. Where are you located and I will see what resources are close to you so you can make the repair?

Bad oven thermostat , if you get me the Brand,model and serial number i will locate the part for you

error code minolte

Try unpluging the oven for 10 min's then plug it back in to reset get back to me , if you still arent working but i will need the brand , model, serial number

F34 ( Upper oven cooling fan air switch not detected ) Replace air switch,cooling ...on door

Hi

"Cal" which means calibration error is caused due to a bad control board. If relay board transformer open (E1 to E2), replace relay board. If still no clock functions replace electronic range control (also called clock or ERC). Hope this helps...please post back for further assistance.

Your touch in put key is stuck, replace ,power relay board and the touch panel Always unplug the oven first before service

this is uper oven over temperature while cooking , check sensor should read 1080 ohms, at room temp, if ok replace power relay board

Hi,

Here is a tip that I wrote about the oven door glass replacement...

Hi,

Welcome to FixYa.

You have not mentioned if the oven has displayed any error code so I will take that for what it is...there was none shown.

With that, I`d start by looking for an over-temp cut-out tripped. Since this problem started following a self clean cycle, it leads me to believe it is just that.

Here`s what and where to look for for this,

Fortunately if it is tripped, they are the manual reset type and are accessible behind the black grill/vent just above the door and just below the control panel next to the lock latch assembly.

**Turn off the 40amp breaker at your service panel or sub-panel in the home before attempting any service...safety first**

With the power off, you should be able to remove the grill and push the red button in the center of the thermostat and that should fix your problem...as shown here, If indeed the hi-limit is tripped you`ll know immediately because you`ll feel it click as you push it down. It will look like the image below...





Ultimately it could be a faulty relay board or related to the timer, but I`d start with the hi-limit cut-out tripped first.

If the images I attached are not clear or you just want more info, I can send you a complete service manual in a "pdf" attachment, however you`d need to provide an email address to where I could send it to you.

Other than that if you call in a pro just be sure they are an authorized B/S/H/ service provider ( B/S/H/ is the parent company for Bosch, Thermador, Gaggenau, Siemens products ).

Let me know and I`ll watch for your reply and respond as soon as I can. Good luck.

Hello,


Welcome to FixYa.

The issue with these displays is they can lose their intensity over time, but also it can be contributed to the main control...specifically the transformer on the "C" series ovens, hence the only remedy is to replace the control/display kit.

I'd first suggest checking the main control if you feel you are capable, this is how...

1) Turn the breaker or power supply to the oven off while servicing...saferty first ( though you will need power to check the transformer, this is where an experienced tech may be necessary, you'll need to decide )

2) locate the control board behind the display ( this will require either moving the front panel or the top panel behind the display...in the plenum )

i.e.



Then identify the PCB/control board...








The large arrow identifies the main control, the small arrow is the transformer location on the board

3) Remove the control or place it at a vantage point you can perform the following voltage checks, this is where some experience or electrical knowledge comes in handy...

i.e.




If the values listed in the test chart all are o.k. then you need a display only...if not you'll need the control board. ( Before you ask, I don't know of any transformer supplier...but then you're gambling nothing else is defective on the control anyway, not worth it in my opinion, that's your call )

Now to answer your question about availability though, one can find these "display's" at "repairclinic.com" for around $225USD and includes what I've attached here...




The "PCB" or control as it is referred to as well is also available at said location for around $175USD, it will include this...



Hope this helps move you forward. Let me know if I can assist you further and good luck.

Macmarkus :)
