Old thermador 1950s wall oven, will not turn bottom elemnt off, does anyone know where to find a wiring diagram? Trying to find a replacement thermostat Maybe a WO 16 or WO 18, no tags or markings on it

Double check each connector to be sure it is installed (aligned on pins) properly. Also check wiring diagram for a safety limit thermal switch. If it has one, push to reset it.

go to sears and take the serial numbers off your appliance and they will get you a new element for it and you can take the old one out and the new one in. Ask them at sears how to do it and they will tell you.

Hello, Welcome to FixYa. Yes this has been a fairly common issue with the Thermador wall ovens as well as their freestanding ranges. Typically the remedy will be replacing the hinges, but there is a "fix" you can attempt in the interim. At least in hope of keeping the oven light from being on all the time, hence damaging the control board which houses the oven lights transformer.

The issue with those Thermador wall oven and freestanding range doors ( especially on the freestanding "professional" line ) is the weight of the door is so great, the hinge will actually move slightly over time, other times the entire hinge will need to be replaced.

This is what I'd recommend ( also official Thermador remedy, rest assured as I am a authorized factory trained Thermador service provider ) before pronouncing the hinges need replacing though.

**This does require a somewhat involved repair, so if you don't feel completely comfortable or have any reservation to trying this, please call in an local authorized Thermador ( B/S/H/ ) service provider.**

Recommendation: Adjust the door box hinge per instructions below.

1. Pull the oven away from the wall about 12".

2. Remove the hinge box cover plates.

3. Remove the vertical side trim piece. It covers one of the screws that must be loosened.

4. Loosen the 4 screws that secure the hinge box.

5. Place a rolled up dishtowel at the bottom of the door and close the door and apply light pressure to the door while re-tightening the four screws.

See fig below

6. Re-install the hinge box covers & side trims.

7. Re-install and secure the oven.

That should do it, ( or as stated, improve the situation ) if the hinges are too far gone they will need to be replaced unfortunately.

Let me know if you require further assistance or if indeed this solved your problem.

Thank you for choosing FixYa today and good luck going forward.

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).

I have just repaired two SC301 ovens myself, but it is alot of work. You can get the oven's LED lights reconditioned at a company called CGI industries. Look them up on the web and click on the link for thermador. Removing the led panel and oven relay board is an involved job, but easier if you do it the correct way. First, turn off the power to the oven. Then pull the oven out of the wall socket about 1 quarter of the way. Remove the top cover of the oven with a phillips screw driver. This reveals the oven relay board. Take a digital picture of the board to remember the wire positions, or alternatively write them down. You also need to remove the touch panel (two screws underneath) and gain access to the LED. Remove the LED panel and wires. ship both to CGI (boards only) and you will have them back in less than a week. Costs about $170 before shipping. Reinstall and turn power on. All is good.

The control switch may be bad on it. If there are 2 elements on the top, they both are not bad at the same time.Check to see if the wires have not burned off the control switch first. Check to see if your breakers are O.K. Turn them both(maybe 3) off and then reset.

very possible hat the element is no good, does it look physically burned???? if so replacing the elemnt is the only option,2 screws and 2 wiredis all, simple to replace, unplug/disconnect power first,,, the wires are always live to the elemnt!!!!!!!

since you said the broiler does work , take the wires off the broiler element and put on the bake . then when you put on the broiler the bake should work . the light bulb principle, just remember to wrap all loose wire with electrical tape and disconnect from wall while working.

ill aasumme that yo can see the elemnet in question, and its not a "hidden bake" elemnet located under the oven floor.. should be an easyrepair, with a little bit of patience. don trush shoudl only take 10 min anyway. TURN OFF POWER> LIVE WIRES TO ELEMENT AT ALL TIMES. REGARDLESS OF UNIT ON OR NOT!!! ther ewill be 2 screws along the bottom of the element holding the elemnt in the unit. after emoving carfully slide the old elemnt out a few inches, slowly pull out, for the wires are still attached to the back of elemnt and you want them to stay there you dont want them to disconnect and fall behind unit, (you will then need to remove the unit form the wall to access htem). so pull slowly espescially if you feel resistance in the wiring. after you getit out far enough simply unplug and plug in the new one reinstalll and you shoud be fine
