Here is a way to deduce the replacement thermocouple you need.
Over the years, Force 10 has made stoves with 3 styles of top burner caps - each of these stoves uses a different series of thermocouples for the various burners:
Model years from 1987 - 1999 have top burners with black cast iron caps that have tabs or holes on the sides. The thermocouples for the top burners are no longer available, but the oven burner thermocouple is still available; use part #890763. If a top burner thermocouple has failed, you will need to upgrade the entire burner. Use kit #89013 to replace the smaller burner (burner cap is approx. 2" across), and kit #89012 to replace the larger burner (burner cap is approx. 3-1/2" across);
Model years from 2000 - 2010 have top burners with a silver cap secured by 2 screws. These stoves use thermocouple #89216 for each top burner, #89282 for the ("tube style") oven burner, and #89283 for the broiler burner.
Note Year 2010 was a transition year, with stoves with two top burner styles being produced. Check your top burner cap to make sure of the style if you need a thermocouple for a 2010 year stove.
Model years from 2010 - Present have top burners with polished silver, dome shaped, twist-on caps. These stoves use thermocouple #60032 for each top burner, #70655 for the oven burner, and #70063 for the broiler burner.
Some Benteau Yachts have a 2-burner custom Force 10 stove #632071 installed. This stove uses thermocouples: #89216 for each top burner, and #89215 for the oven burner. (This stove has no broiler.)
