i have a frigadaire air conditionermodel@ fac125p1a2. i need part# ap3681595. on the part diagram the part# is 3. but the model fac125p1a2eng says it is part #ap3997790. and on the part diagram the part # is 11.is part 11.is the slider that holds the accordian piece,the same as the part in the part diagram of model fac125p1a2 part #3 .all i need is the left hand slider frame that holds the accordian piece. to me part #3 looks like it could replace the other partfrom the other model,and it would be a lot cheaper if it would fit proper, any info on this would be much appreciated, GrindFreakMike@yahoo.com
