Fresh Food Strip and
Wall LEDs
Diagnostic code 60 will turn on the strip LED lights in the
Fresh Food ceiling and the Fresh Food vegetable drawer,
and the circular LED wall lights. This test will turn on these
LEDs from dim to 100% within 3 seconds of activation.
The main board outputs 12 VDC on pins 5-6 (brown to
blue) for the ceiling strip and 7-8 (brown to blue) for the
vegetable drawer strip on the K107 connector.
The power supply board controls the wall LEDs, not the main board. The power supply sends out 24 VDC
on a series circuit for all LED boards from K301. Each LED board will drop 3 VDC and if one fails they all fail.
The individual LED boards can be tested using the Diode function on a multi-meter. Checking across the 2
pin connector on each board should result with a .7 VDC reading on the meter, an open (OL) reading would
indicate a failed LED.
