Viking oven not heating past 150 degrees - Viking VDSC365-6B Dual Fuel (Electric and Gas) Kitchen Range

you either have a bad bake element or control. also check wiring between

when you say now it lights. is just the ignitor lighting?or can you hear the gas flowing??? can you feel it heating at all?? should start at 100 degrees and climb up from there. no reason for it not to heat past 200 (unless set to Celsius which default setting of 350 =190degress) therefore will not heat past 200. and wont let you try to heat to 425 , that would be off the charts of Celsius conversion. sensor problem would eitherno t let stove come on or wouldnt stop from heating eitherway a code would come up in the display

this can be problem with the temp probe.and or the control board if your unit is equipped.

It sounds like a weak igniter.

One of the door hinges was loose. You have to lift the door by the handle to open it.

The element will have to be replaced if there is no power going to it.

u sure the flame is lighting sounds like it isn't make sure u physically see the flame u might just be seeing the glow of the igniter if it doesn't light more than likely the igniter needs to be replaced

Most of the time it is a temp sensor in the oven. We bought a service manual at houseneeds.com and fixed ours.

good luck.  We have the same range and have had issues with the ovens since the range was installed.  The overn does not heat evenly on convenction or bake.  Thermadore doesn't stand behind the product and neither does the distributor.  They tell us that Thermador isn't standing behind the product so there isn't anything that can be done.  We spent $8000 for an oven that burns the back corners of everything we bake.
