GE ZSC 1001 Low Voltage Transformer, To remove the selector board, To remove the control panel

Page 28

To remove the selector board:

1.Remove the control panel bracket. (See Control Panel Assembly.)

2.Pull the dial straight out from the control panel.

3.Disconnect wire harnesses from the selector board at locations CN9 and CN13.

4.Disconnect the wire harness from the control panel at location CN14.

5.Remove the 6 Phillips-head screws that attach the selector board to the control panel.

Low Voltage Transformer

The low voltage transformer is held in place by 2 Phillips-head screws.

The control panel must be removed to access the low voltage transformer. (See Control Panel Assembly.)

The low voltage transformer is connected to the power board at location CN7 and on the relay board at location CN1.

CN13

CN9

To remove the control panel:

To access the control panel it is necessary to remove the control panel bracket, control, display, and selector boards. (See Control Panel Assembly.)

Resistance Check

1.Disconnect the harness from the relay board at location CN1.

2.Check the primary winding for approximate resistance value between the white and black wires of 23.2 Ω.

3.Disconnect the harness from the power board at location CN7.

4.Check the secondary windings for approximate resistance value between:

•Yellow to black - 1.5 Ω

•Black to white - 5.2 Ω

•Red to brown - 1.1 Ω

Note: Voltage check for the transformer is:

•Yellow to black - 13 VAC

•Black to white - 20 VAC

•Red to brown - 8 VAC
