C302 bottom oven not turning on when you touch the display switch that switches between upper and lower ovens, The touch pad was replaced.

being transformer is low voltage probably shorted

I sought to replace the air flow switch. Herein is the problem. The switch is not present. AmanStino Mouse Pad with Gel Wrist Pad blue9 0 7 8 AmanStino

I assume yiu had the electronic oven control repaired. Sometimes the touch pad also goes bad. I have had to replace them at the same time. If the oven indicator lights showing the oven being on shows up on the display it could be that the thermal fuse behind the oven has gone out. this in in the common line and will shut down both ovens at the same time but you will get the control panel to respond to the touch pad.

To Set a Cook T ime:
1. On double oven models only, press UPPER OVEN or LOWER
OVEN for the one you want to set.
2. Press BAKE or CONVECT UPPER (on some models).
Press the number pads to enter a temperature other than the
one displayed.
3. Press COOK TIME.
4. Press the HR and MIN "up" or "down" arrow pads to enter
the length of time to cook.
5. Press START/ENTER.
The start time and stop time countdown will appear on the
oven display.
On double oven models only, when both upper and lower
ovens are being used at the same time, touch UPPER OVEN
or LOWER OVEN to display the respective cook time.
When the stop time is reached, the oven will shut off
automatically and "End" will appear on the oven display.
If enabled, end-of-cycle tones will sound, then reminder
tones will sound every minute.
Repeat the process by choosing the other option of UPPER or LOWER OVEN

Hello,

The F7 error coode means either the ERC or touch pad is bad. Having already replaced the ERC,replace the touch pad(the part w/the ribbon cable)

Hi,

Below is the complete instruction sheet.

You are having a communication error between the appliance. Here is the actual tech manual instructions for that code:

PROCEDURE: Before proceeding, press OFF, OFF, START to enter Diagnostic

mode and verify the error codes. Ensure AM software, UI software and EEPROM

CHECKSUM versions appear on the lower text line. If AM software and EEPROM

versions do not appear, UI and AM may not be communicating. Verify this for the

lower oven UI and for the microwave (upper oven) UI. The lower oven UI will show

the AM software version for the lower oven appliance manager, and the microwave

UI will show the AM software and EEPROM versions for the microwave appliance

manager.

If the lower oven UI is not displaying the AM software version, go to UI IS NOT

DISPLAYING AM SOFTWARE VERSION.

If the upper oven UI is not displaying the AM software and EEPROM versions,

go to UPPER OVEN UI IS NOT DISPLAYING THE AM SOFTWARE AND

EEPROM VERSIONS.

If lower oven UI and microwave UI are both displaying an error, go to LOWER

OVEN UI AND MICROWAVE UI ARE BOTH DISPLAYING AN ERROR.

UI IS NOT DISPLAYING AM SOFTWARE VERSION:

A. Unplug oven or disconnect power.

B. Open the back panels and make sure the P6 and P2 connectors are fully

inserted on the appliance manager and on the lower oven user interface board.

- If they are not plugged in, plug in connectors and go to step F.

- If they are plugged in, go to step C.

C. Visually inspect all wires between P6 on the appliance manager and P2 on the

lower user interface.

- Make sure wires are not cut or pinched.

- If the wires appear to be intact, perform a continuity check between

P6-1 of the appliance manager and P2-1 of the user interface board.

Complete for P6-2(AM) to P2-2(UI), P6-4(AM) to P2-4(UI) and P6-5(AM) to

P2-5(UI). All the measurements made should be less than 5 ?. If any of

these measurements exceeds 5 ?, go to step E.

D. Replace the appliance manager. Ensure all connectors are properly inserted.

E. Replace the wiring harness (signal). Ensure all connectors are properly inserted.

F. Replace all parts and panels before operating.

G. Plug in oven or reconnect power.

H. Observe for longer than 1 minute to determine if error has been repaired.

I. If error does not appear, initiate a bake cycle. Let the cycle run for at least

1 minute.

- If no error occurs, cancel the cycle, the problem has been repaired.

- If error occurs again, restart the troubleshooting procedure at step A.

At step D, replace the lower oven user interface board if appliance

manager has already been replaced.
- If both are replaced the problem has been repaired.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Hi, i found out from Thermador customer service that error code F64 means that the lower fan switch (located inside the bottom trim on the right side) is not being detected as closed. In my case, this was because the header (P4) on the Display panel had broken loose from the PC board and was no longer making contact. P4 is where the lower fan switch wires connect to the control boards (actually the display panel).

There is a short circuit between the lower oven control and the lower element.
Disconnect the lower element. Put electrical tape on the loose terminals and turn the lower oven on.
If it does not blow, replace the lower element with a new element.
If it does blow, Check the wiring to the lower element for continuity to the frame of the range.
If you get continuity replace the damaged wire..
Finally, check the control knob switch for continuity to ground on the frame of the oven.
