I am not sure what part you are wanting to replace. Without a complete model number I can't access any information on your range.
Your range probably has a safety thermostat located under the cooktop. This thermostat would cause the oven to stop working.
The temperature of the oven is controlled by the clock which is an electronic oven control. There is an oven temperature sensor mounted to the rear wall of the oven.
You can see a parts diagram of the range at [www.partsdirect.com?sid=MMLxexpertxmerch
]. You need to get the complete model number off the range to be sure you are ordering the correct part. The model number is on a tag on the frame of the range. It is located around the opening the storage drawer slides into.
There is no service manual to get, but we can send you images showing instructions for replacing parts on the range.
If you have more questions, reply on this thread and include the complete model number of the range, I will be glad to help.
