STRIP CIRCUITS

•    Before checking the oven circuitry, be sure to check the line voltage and the fuse or circuit breaker.

•    Check for loose or incorrect wiring inside the range.

The following strip circuit diagrams are to aid the servicer in diagnosis and repair. The diagrams are shown in the ON position.

1)     Ref Line (Reference Line) is the (+) positive potential of 12 VDC. Main PCB Board switches the (-) negative potential of the 12 VDC to each relay coil. With BK meter lead on Pin 1 Ref line and RD meter lead on Pins 2 thru 6, your meter will show -12 VDC.

2)     DLB will have -12VDC along with BAKE, BROIL, WM DRWR, or CONVECTION relay. Measure from Pin 1 (Orange) to any relay coil being tested.
