UI Board Tests

• Run Test 01 for LED operation.
• Run Test 02 for viewing and changing model ID

code.

• Run Test 03 for UI software version.
• Run Test 18 for UI Critical Software Version.

UI Board Diagnostics

1. Check for 120 VAC at IMC J101 pins 2 & 3.

a. If 120 VAC is present go to step 2.
b. If 120 VAC is not present check house supply

voltage.

2. Check for 12 VDC between IMC J603 pins 1 & 4

and 7.5 VDC between IMC J603 pins 1 & 3.

a. If either voltage is not present replace the IMC

board.

b. If both voltages are present go to step 3.

3. Check for 12 VDC between UI J201 pins 1 & 5 and

7.5 VDC between UI J201 pins 3 & 5.

a. If either voltage is not present, check wiring

between the UI board and the IMC board.

b. If both voltages are present, replace the UI

board.

UI Board Removal
