Robert B Eighty Four , PA March 22, 2019 F73 Replaced main board. Board was in in a day. Easy to install. Note: I can read basic wiring diagrams, however the orange wires need to be installed in the same contact. TAKE A QUICK PICTURE WITH YOUR PHONE OF THE WIRING PLACEMENT. YOU “WILL” be glad you did. Excellent service from APP. Thank you. Rsb 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
