Good day,

   Today I first confirm that both L1 and L2 are present at the incoming terminal strip

L1 (R9) to N (W3) 123VAC
L2 (BK-2) to N (W3) 123 VAC

Now before calling any bake or broil programs, I check all pins on EOC against ground with all wires connected

Bake P2 = 0 VAC
Broil P3 = 0 VAC
L1  P1 (Connected to L2 via BK-2) = 6.8 VAC
L2 Out P4 (connected to L1 via R-9) = 0 VAC
L2 IN P7 = 7.1 VAC
Between P4 and P7 = 35.9 VAC


Next Call for Bake at 350 and Check again

Bake P2 = 6.7 VAC
Broil P3 = 6.7 VAC
L1  P1 (Connected to L2 via BK-2) = 6.7 VAC
L2 Out P4 (connected to L1 via R-9) = 6.7 VAC
L2 IN P7 = 7.2 VAC
Between P4 and P7 = 250 VAC

One more time with Y-2 and BL-2 disconnected from OUT P7 (BR-2)

Bake P2 = 6.6 VAC
Broil P3 = 6.6 VAC
L1  P1 (Connected to L2 via BK-2) = 6.6 VAC
L2 Out P4 (connected to L1 via R-9) = 0 VAC
L2 IN P7 = 7.1 VAC
Between P4 and P7 = 0 VAC

and just so we are on the same page, this is how I am reading the schematic vs the physical layout

Schematic                            Board
Bake P2 ----------------------- Bake P2
Broil P3  ----------------------- Broil P3
L1    P1  ----------------------- L1  P1 (Connected to L2 via BK-2)
IN    P4  ----------------------- L2 Out P4 (connected to L1 via R-9)
OUT P7  ----------------------- L2 IN P7
