COMPONENT TEST
U CAVITY LED LAMP
1. Check for foreign material on cavity lamp hole and LED lens
2. When door is OPEN, check for approx. 24VDC across the connector terminal connected to LED
with the LED unplugged. This confirms that the PSU unit DPWB-B696DRKZ is working.
3. Check the connector and harness to the LED lamp to ensure sure they are properly secured
and not broken.
4. Checking if LED lamp is defective:
a. Open the outer case, unplug the LED lamp connection.
b. Use a diode function on the multimeter if available to check if the LED turns ON when the
positive probe is connected to the positive terminal (white wire) of the LED and the negative
probed is connected to the negative terminal (black wire) of the LED.
c. If the LED turns on (dimmer than normal), then the LED is working properly and the PSU
unit (DPWB-B696DRKZ) is not working or the harness has a defective connection or connector.
d. If the LED does not turn on, then the LED is defective.
