Walter H Bremerton , WA April 29, 2017 Appliance: Model CYL222OBDB Range oven would not stay lite once i had the pilot light lite but released the knob I ordered a new thermocouple. The first one I ordered was the wrong one for my model range. My fault...I couldn't find the model number of my range until after I ordered the replacement part. When the right thermocouple came in I installed it and tested the over...works well now. If you ever have to replace the thermocouple, you do have to remove the range in order to replace it. There is a clamp in the back of the oven that will have to be removed that holds the gas lines and thermocouple to the back of the range. Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
