Marilyn B Sylvia , KS December 19, 2015 The oven thermostat knob had been destroyed on my tappan range Thanks to the handy parts cross reference guide and the blown apart schematics provided, I was able to locate the correct knob for my specific range in under a half an hour. Easy online ordering was a breeze and three days later, I had the part. Never thought it would be so easy and certainly not that fast. Thank you, Appliance Parts Pros.com.
