Thermador... | Answered 13 hours ago


I wanted to post this up in case someone has trouble finding an answer and what worked for me. I found somewhere else that the 43 code (4 preheat;3heat) blinks was specific to the cooling fan or the temp sensor. I had started to remove the temp sensor off the back wall of the oven but was unsure where the wire ran to. There is a specific Ohm value it should have around 1080 I think (not 100% postive).
What I found during that search is what solved the oven problem for me. On the top of the range, if you pull off the grill grates and remove the center stainless cover you can access under the burners. You can do this without removing any wires or hardware. In the back of this area is a small cover held in by 4 screws. Remove that. Underneath it is the cooling fan switch. It is a mechanical switch that when the fan kicks on it pushes a metal sail that then causes a connection in the switch letting it know the fan is operating. This switch had a little bit of corrosion on one terminal but it is also prone to getting dirty. Clean it off and try to restart the oven. The sail should move forward and the switch makes connection. For me once it was cleaned and any corrosion cleaned off, my oven worked just fine. This is a pretty easy check with the 43 code since it does not involve a lot of invasive work. Hope this helps someone.

Hello Amvmotors,

I understand that you want to convert your Natural Gas unit to LP (Propane) gas you will need to purchase a conversion kit. Please give me about an hour or so and I will locate it and the instructions to convert.

Thank you for choosing FixYa.com

Thanks Marty for the info on the sail switch. We experience the same error code 43 problem. Seemed like the sail switch was stuck in the back position and didn't come forward when the fan started. So I bent a metal coat hanger and used it to pull the switch foward to "unstick" it. I tested the oven turning it on and off a few times and made sure that the switch moves forward with the blower fan starting when the oven was on, and moved back when the oven was turned off. Should be obvious, but make sure the blower is not running and the oven is turned off before you stick the wire hanger back there. A pretty quick and easy thing to try before calling the repairman.

you have to turn all knobs to off including the outer selector dials on the outer part of oven temp knobs
once everything is turned to off shut breaker down for 2 min then turn on should reset

This is a very involved job. The cooktop has to be removed to gain access.

Take the bad one out and one that you know works. Compare them to see if the tube is clear and the air shutters are adjusted the same openings

That error is indicative of a failure of the software in the display module. You can try to reset it by unplugging the appliance for a few hours. If no change, the display module will probably need to be replaced.

your oven does not have a glow coil ignitor it has an electrode and a 3 dsi ignition boards 2 broil 1 bake
your dsi spark coil has failed or you have a grounded ignition wire
you need to call for service
DO NOT MATCH LIGHT THIS OVEN
it has its own saftey device built in it will try to fire and proof flame up to 3 times then lockout to avoid gas building up
