These parts... Part Number: AP2106141 and Part Number: AP2107936
Made by FRIGIDAIRE (Knob - rotary) seem to be identical. I was wondering if they were interchangeable since I would prefer to buy the one that is least expensive! Thanks.

Answer Hello Paula. We recommend that you purchase the knob that is called out according by model number 131141105. You are more than welcome to try the other knob, we are unable to advise if it will be compatible or not. The difference on the two could be the lenght of the shaft, which we have no way of determining.
