SOURCE: Bosch HBN 455 Oven Cooling-Fan Issue

Our HBN655 had similar issues- the upper cooling fan would cycle on and off on a relatively quick duty cycle until the whole mess cooled off enough and it shut off.
My workaround is to turn the temperature dial off but leave the oven function dial on to BAKE. This seems to force the fan to stay on; then we shut it off a while later and avoid the annoying fan cycling.
(note- 2 years ago, our fan became intermittent, varying speed, etc... for about 2 months before it quit entirely. When that happened, the oven started to heat then the thermal cutout kicked in and the oven shut down entirely. We ended up replacing the fan and that fixed the bug... except now it's starting to act up again...)
(also note- the racks on this beast have a faulty design. if you have a heavy casserole and slide the rack out all the way, it tends push the sidewalls apart and the rack drops. I spoke with Bosch about this and they sent me new racks, no charge... so they know there's a problem. But the new racks don't fix the bug; they just make it harder to reproduce. I have actually had one rack fall with 2 piping hot casseroles on it. Fortunately no one was hurt.)

SOURCE: Thermador SC302T clicking noise, locked door after power outage

iodine, open the upper oven, look thru the grill below the control panel on the right side and there is your model number. The issue here is that when the power came back on the oven run thru a test and your lower lock motor has failed. It will need to be replaced. Yes the only way to stop this is to shut off the breaker.

SOURCE: Neff U1721 bottom oven not heating fan & light are ok

Yes it will need a new element, if the fan runs and temperature light comes on then the element is gone.

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 overtemp cut-out tripped. Did this problem start following a self clean cycle ?

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...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 you feel capable of repairing this yourself 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.

SOURCE: GE Monogram double oven. Zet2sm1ss F9

An F9 error code on a General Electric (GE) oven indicates that the oven's electronic control system has detected a problem with the automatic door lock. The automatic door lock mechanism prevents the oven door from being opened when the oven is set for "Clean" mode. The malfunction may be a jammed door lock mechanism, a pinched or broken wire, a faulty lock switch or a fault in the control board itself.
Disconnect power to the oven.

  • Open the oven door. Remove three screws from underneath the oven's control panel. Lift the control panel straight up to disengage the mounting pins on the top corners of the panel, then tip the panel toward you.
  • Inspect the door lock mechanism. The mechanism is in the lower left area of the space behind the control panel. Rotate the cam on the door lock mechanism to be certain it moves without binding. Replace the mechanism if its mechanical parts do not function properly.
  • Inspect the wires that connect the door lock mechanism to the control panel. Check for pinched or broken wires. Check for wires with frayed insulation. Repair wires as needed if defects are present.
  • Locate the six-pin connector on the door lock motor on the right end of the door lock mechanism.
  • Rotate the cam on the door lock mechanism to the unlocked position. Test the resistance between Pin 3 and Pin 1 of the door lock connector with the ohmmeter. The resistance should be 0. Replace Lock Switch 2 of the door lock mechanism if the resistance reads other than 0.
  • Rotate the cam on the door lock mechanism to the locked position. Test the resistance between Pin 3 and Pin 2 of the door lock connector with the ohmmeter. The resistance should be 0. Replace Lock Switch 1 of the door lock mechanism if the resistance reads other than 0.
  • Contact a certified GE appliance repair facility if the source of the F9 code has not been discovered. Troubleshooting the oven with the electric power turned on is a job for a certified technician
  • general electric stoves with electronic controls, if there is a problem it will display the problem with a F followed by a number here are some of the codes and what they mean.

    F1----STUCK KEY--DAMAGE CONTROL

    F2----OVEN TEMPERATURE EXCEEDS 590 DEGREES WITH DOOR UNLOCK

    F3----OVEN SENSOR DEFECTED

    F4----OVEN SENSOR SHORTED

    F5----ELECTRONIC CONTROL NEED TO BE REPLACED

    F6----THERE IS A PROBLEM IN THE KEY PANEL

    F7----REPLACE KEY PANEL

    F8----COMPONENT FAILURE

    F9----DOOR CIRCUIT---LOCK MECHANISM OR WIRING

    FC----DOOR LOCK CIRCUIT FAILURE

    FD----PROBE OR RECEPTACLE FAILURE

    FF----ELECTRONIC CONTROL FAILURE

    HOWEVER ON THE MORE EXPENSIVE MODELS AND PARTICULAR THE DOUBLE WALL OVENS THE COMPUTER CONTROL AND THE TOUCH PAD ARE TWO SEPERATE COMPONENTS.

    THE TOUCH PAD IS USUALLY IN THE GLASS FRONT THAT COVERS THE CONTROL--ON THESE MODELS YOU WILL SOMETIMES GET A ---F7--CODE----

    WHENEVER THERE IS A-- F7--OR--F1--ON THIS MODEL IT MEANS THE PROBLEM IS EITHER IN THE CONTROL OR IN THE TOUCH PAD

    C302U Double Oven cooling fans shut off immediately after finishing bake cycle. Replaced control board, still does the same. What controls the cooling fans to protect the circuitry?


    Newer versions of the control board software will run the cooling fans for a bit after the cycle ends, but many older models work like yours does

    I have a Thermador Model C302U wall oven the fan on the uppper oven starts and then stops and I get the F34 code I am thinking to replace the motor but I want to know if there are other things I should...


    When that fan starts up the air pushes against an air switch and that tells the board the fan is blowing. The stove uses a DAC system that relies on switchs to confirm the operations of the fan. the DAC control uses signal voltage to detect switch function. The air switches must physically close by air movement from the cooling blowers before the oven proceeds into a bake or broil mode. Reason being f the cooling motor does not function and the oven goes into a bake or broil mode, the oven will overheat and could damage the fancy smancy over engineered piece of garbage electronic components. My opinion. This is not for the DIY unless you are a TV repairman.

    CODE F64 WHEN TRYING TO USE THE BOTTOM OVEN.


    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).

    F64 error


    Hi,

    The F64 on those oven`s is indicating the onboard watchdog ( control board ) has detected the cooling fan for the lower oven isn`t being detected or isn`t funtioning.

    That may or may not be the problem though. I`ve found often it is actually the "sail switch" located in the vent of the oven ( at the bottom where the unit exaust`s ) is stuck either due to grease or being damaged during installation.

    You`ll likely want to call in a pro to actually determine what is in fact initiating this error code, but it is definetly related to the lower cooling fan circuit.

    Let me know if I can assist you further. Thank`s for visiting "fixya" for your oven inquiries and good luck.

    If you feel as though you are capable to service this on your own let me know and I`ll attempt to guide you.

    Thermador built-in double wall oven -- replace cooling fan?


    No, do not try it yourself. When the motor is bad sometimes it won't have the power to start itself. With a push it will take off. If you try to remove it yourself you will risk damaging cabinet, the oven itself, floors and/or yourself. Please trust your repairman. We are trained and experienced. Not everyone Is out to get you!
