Karl W Colorado Springs , CO November 05, 2014 Appliance: Model DACOR COOKTOP MODEL SGM464EM Dacor cooktop spill protectors indicator rings flanges had broken off so would not fit securely in the cooktop hole the original replacements were no longer available I looked for similar protectors, but the description indicated that the three would not work on my model cooktop. But since they looked like the discontinued part 86539, I measured the flange hole and e-mailed Applicance Parts to determine if the available disks would work with my model cooktop. A prompt reply was yes, so I ordered 2. The replacement parts 700666 arrived promply in a few days. They worked. The only difference was one indicator was not in red as in the original. The service and result was exceptional. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
