I have a viking...

I have a viking VGSC with 12" griddle. The griddle will only turn on when the knob is all the way to 400 degrees, and then it turns off before it heats up

Contractor's Assistant: Can you guesstimate how old your Viking is? And just to clarify, what's the exact model?

The VGSC is the model #

Contractor's Assistant: Do you plan on doing the work yourself?

Yes

Contractor's Assistant: Anything else we should know to help you best?

It has a copper thermocouple connected to a copper wire that slides under the griddle

Unfortunately this is a common issue with Viking griddles over time. This issue means that your thermostat with the thermocouple connected to it has gone bad and needs to be replaced. This is the part that your knob itself attaches to which you turn when you twist the knob. Now if you order a new one, you can order one at AllVikingParts.com if you give them your full model number. The key when replacing the part is to route the thermo couple so that it does NOT touch the flame at all. When the griddle is seated down, if the flame touches the copper wire this thermostat will fail much quicker than intended so make sure it runs directly down the center of the burner into the channel below the griddle where it monitors temperature.

We are on the honor system here.

you are saying the thermostat has gone bad, or the thermocouple? Where is the thermostat located?

It's all one part. That thermocouple is attached to the thermostat which is the part that your knob attaches to on the front of the control panel.

I can not find it on their website under the griddle section. They are unable to help me because the serial # is worn off. Any idea what group this item would be under?

Hi Tyler, I finished the repair today, and you were correct, it was that part. I gave 4 stars because after you pointed me in the right direction, I found that you could do a resistance test on the thermostat to verify that it was bad, and I felt like it would have been helpful of you to mention that there was a very simple test to do on the part to verify it was the culprit before spending over $150 on the replacement part. Thank you for your help, Jon

Alright well I'm glad I could help you. I understand you would have liked to do a test on the thermostat, that being said as a technician I wouldn't have even thought about doing such a test because nothing else can cause the problem so there was no need to test given the possibilities.

Well, after heating it a few times to varying degrees of heat to re-season the cast iron, I went to actually use it the morning and it again would not turn on until the knob was at about 350, I doubt it will fully heat but I will wait and see. The copper wire is as far away from the flames as possible.
Customer reply replied 1 year ago
after working 3 times, I am now back to square 1

The new thermostat has been ruined again. Somehow that wire isn't routed properly and the flame is touching it is if was ruined after 3 times. Hopefully you can return the thermostat and get a new one, but it's not being routed properly if it failed so quickly again.
