P6 Send 18 VDC to the Microwave board to snap K1 relay closed and 5 VDC to
the microwave board to activate the triac.
P9 Sends current to the upper oven latch switches. It is a 4 pin
header. All 4 pins are used.
P10 Sends current to p10 header on the display head. It is an 8 pin
header. All 8 pins are used.
P11 Sends current to Pl 1 header on the display head. It is a 9 pin
header. All 9 pins are used.
Pl4 Sends current to the upper oven double line break relay coil.
it is a 2 pin header. Both pins are used.
Pl5 Sends current to the lower oven double line break relay coil.
it is a 3 pin header. Only #l and #3 are used. #2 is missing on the
