Viking DED0530TSS oven calibration?

Please provide more info re what needs calibration on your Lily, and which model of Lily is it.

use a digital thermometer with a probe inside the cavity, normal preheat is 30 mins to 350, wait until the 3rd cycle to see what temps are in the cycle, record high , low temps add and divide. plus or minus 10 are in scope. ex 350 on at 340 off at 360 will avg 350. depending on the serial and age, there is no calibration unless your Electronic thermostat would be suspect. Hope this helps.

i couldn't find your model on the sears site,every viking stove i've worked on had two ignitors,if one of the ignitors isn't working correctly could cause heat changes in the oven.if you pull out the racks,then remove the side rack holders,lift up the floor so you can see the ignitors,start the oven,as soon as the ignitors start to glow time them,if they don't ignite the flame within 40 seconds the ignitor is bad.if this is the problem you don't have to calibrate the oven.also if the ignitor or both are bad check the burner tube to see if there's a hole in it.my friend john had trouble with his oven,i went over,had to change out both ignitors and both burner tubes,the ignitors weren't working correctly and burnt a hole through the tube.so check the ignitors first,if you want to calibrate it look at your manual and it should tell you how to do it,or oull off the thermostat knob,look on the back there might be screws there to calibrate it or if there's a hole in the shaft in the shaft that you pulled the knob off of you might need a small screw driver to stick in there,turn it slowly and not to much to the right to increase the temp.hope this helps but start with the ignitors,they are usually the problem.

Not familiar with the brand of course but if your model has an Eaton oven control like this one for Viking Page 23 their is an adjustment screw for calibrating the oven temps. Other controls use an adjustment inside the shaft of the oven control itself.

Go to partstown.com and look up the service manual and calibration steps for your stove.

Without the Model Number I can only give you Basic instruction.

If your machine is Digital the best way to calibrate if find the manuel of your machine useing your Model number.

Some of the digital models : select bake and press and hold the up or down Temp button for 5 Sec to enter the calibration mode.

Some models require you do get the temp to over 400 deg befor you can enter the Calibration mode.

If your machine has a turn knob ... Take the knob off and see if there is a small screw in the center... This is the calibration screw.

It does not sound like the guy is trying to rip you off. Most mechanical thermostats are adjustable by a center screw in the oven control knob stem behind the knob. The problem is when an oven is off by more than 30 degrees they become almost impossible to calibrate correctly and it is better to replace it. There would not be any danger in just using the thermometers and just living with the problem. It would be a very expensive fix for a Viking and if you can live with it then you are better off. The parts alone will probably be over $300 and then there is the labor charges. The thermostat assembly also includes the tempature probes so it requires major range dis-assembly to replace it. Sometimes the oven control knob will have an adjustment screw on the knob istelf(back of knob) to adjust the position of the dial ring to match the correct oven tempature. This can allow you to change the position of the knob to match the actual tempature of the oven. They usually will only go 30 degrees one way or the other though. So my advice is that if you can live with it and are able to still cook properly then put off fixing it. If you find that over time the cooking tempatures start increasing then you might have no choice but to have the thermostat assembly replaced.

Sorry for the cookies have you tried going to the viking web site and downloading a manual on your oven. Usually they will explain how to calibrate the oven. Hope that this helps if not let me know please thanks

how bad is the temp off?

Take the oven knob of and in side the shaft of the thermostat there is the adjustment screw for the calibration. first set the oven at 250 degrees and check in 20 minutes without opening the oven door,now check the thermometer. if it's lower turn the screw just lest then a quarter of an inch, the same way the oven knob goes from low to high, holding the shaft of the thermostat so that it will not move.

Electric ovens are calibrated behind the temp knob. Pull the knob straight off of the shaft and look at the back of the knob. There should be a metal slide with a scale and a little set screw. Loosen the screw and move the slide in the direction indicated for your needs.
