Justin B Cypress , TX July 04, 2017 Appliance: General Electric Electric Oven JTP30SM2SS Ge Oven Jtp30sm2ss: Original faceplate brittle/cracking retrofit only option. How to replace Board Housing Assembly (Control Board). Purchased the following parts: AP4484499 - Panel and Bracket AP4484272 - Board Housing AP4484324 - Faceplate The original 752 screws DO NOT work for the retrofit. You will need the newer 752 screws (AP4380294) x6 or similar to attach the Board Housing to the Panel and Bracket. Also used some double sided sticky tape to reattach the GE emblem. 12 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
