Troubleshooting F64 error. DIY at this point; three techs did not fix issue. If both ovens are on, they will simultaneously shut off with F64 error. Will not turn on unless cooled down, and then only one. Does not happen consistently. Thinking it could be 1. faulty blower; 2. faulty PCB; or 3. problem with the air flow in back, ie the back of the oven leaking air somehow. Thoughts?

SOURCE: Error code F64 on lower

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).

SOURCE: Bottom Oven Does not work - F64 Code on Panel

If you look under the bottom door you will see a 3/4" tall slot the entire length of the door. This is where the cooling air blows out. In the middle of this slot is the air switch enclosed in a 5" long metal housing. You can see a thin metal paddle sticking out of each side of the housing. These paddles are spring loaded to angle slightly back. When the fan is on, the airflow will push the paddles forward. If they do not move forward, then you will get the error code. The simplest solution is to vacuum out all of the normally collecting dust that keeps the paddles from moving. To better access and clean the area, the black trim piece that forms the slot can be removed by unscrewing the two retaining screws. That can be more easily accomplished by first removing the lower door. This is very simple. With the door fully open, rotate the small metal clip on each hinge so it hooks over the protrusion on the other part of the hinge. Then lift up on the door (close it part way) and slide (pull) the door and hinges out of the hinge slots. There is no need to remove the entire unit from the wall.

Error F68, beeping continuously

Hello Rasheda, this is Z. Thank you for your post!

If you are getting an error code F68 on your Electrolux oven, it typically means that your appliance may be experiencing an issue with the incoming line voltage. One of the best ways to determine if this is a false error code is to rest the power to your oven by either unplugging it or flipping off the breaker for about ten minutes. If the error code persists, it would be advisable to contact an experienced appliance repair tech since this is not a simple DIY job. He/she would need to determine whether the problem rests with the power supply voltage or EOC (Electronic Oven Control). I hope this helps explain the error code you are receiving.

I am getting an F64 error message. what is this trying to tell me?

Hello,

Welcome to FixYa.

The "F64" code on your model of Thermador double oven indicates the control has detected an error with the airflow for the lower oven ( all lower codes start with "6", upper start with "3" )

This could indicate a faulty blower motor, not coming on at all, or if it does come on and still initiates an F64 error it is likely the sail switch is sticking. It can be removed and cleaned as they do become contaminated with dirt, grease and dust over time.

The sail switch is located at the very bottom of the ovens where the grill is, under the lower door.

( F64 can also be initiated by a failed "K4" relay on the control board, but that is less likely )

It can be accessed by way of removing that grill, however it is something usually best left to an authorized B/S/H/ service provider as it can be quiet involved and is better to pull the unit from the wall.

**Turn off the 40 amp breaker to the oven before attempting any service...safety first**

B/S/H/ is the parent company for Bosch, Thermador, Gaggenau, Siemens.

Let me know if I can assist you further regarding this issue and I`ll try to be available asap.

Good luck.

Oven keeps switching off

Hello



First double-check the gas supply. Look over the gas valves on the back of the oven to make sure gas is able to flow into the oven. If those look OK, call the gas company to see if there has been an interruption in service to the area or to the house.



If the oven grows too warm, the thermostat might malfunction and the thermostat is probably to blame for what you are experiencing.

The thermostat is the part of the oven that tells it when it has reached the desired temperature, shutting off the heating process. If one of the thermostat's components is broken or dirty, this can render the thermostat useless.

Cleaning and replacing the thermostat components is a process best left to professionals because untrained hands can easily break a thermostat that simply needed cleaning. If you suspect this is the issue, contact your local gas company. Sometimes, gas companies offer oven thermostat repair services.

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.
