KGRA806PWH00-Range powered off 2x after sel-clean cycle.
Replaced/reset thermal fuse. During cool down made loud vibrating sound from old blower motor.
ORIGINAL CAUSE IS BLOWER-OLD P/N-8300223 (1500RPM) with new blower P/N-9759320 (2250RPM).
Problem with old motor was it slowed down and could not cool properly due to C-Frame MOTOR armature (rotor) delaminating, getting caught in magnetic field slowing down, causing noise and vibration.
Relpacement was easy-All work done from back of range.
1.Pull range away from wall.2.Shut off gas and disconnect power.3.remove braces and back panel.4.blower cover is held in wit 4 screws. Rather than offset screwdriver-remove side panels to access 4 screws.5.Remove old blower.6.Replace new blower and reassemble all. Works better than new. Great air flow, no noise or vibration.
Good Luck and have fun!
