DRAWER OPEN ERROR
Cause
Main PCB not detecting that Reed Switch 2 is closing when the drawer is closed.
Reed Switch 2 is a normally open(NO) switch.
Solution
Check drawer alignment and switch.
DETAILS BELOW:
1.) Is the drawer closed?
Is the drawer warped or misaligned?
2.) Unplug the unit.
Check Reed Switch 2 for a loose connection at switch & board.
3.) Unit still unplugged. Locate connector WH8 on the main PCB. Set your multi-meter to read resistance and test Reed Switch 2 measuring from pin7 white to pin8 white. Resistance should read < 1 ohm when the drawer is closed.
If the switch does not close, test the switch with your own magnet. If the switch closes now, suspect a drawer alignment issue or missing magnet in the drawer. If the switch still does not close, suspect a bad switch or harness failure. The part location for the harness that includes both reed switches is M022.
Below Info is from model WD200 (Always consult your service manaul for your specific model.)
For models WD300**
This Model has only one reed switch
To test, either access the reed switch by removing the front of the drawer, remove the two screws on both sides and the two screws behind the Control Panel. Once the reed switch is accessed use the connector to test the switch with an external magnet.
Or Access the Main PCB from the rear, find the White 5 pin connector with only two White wires. Disconnect and test the reed switch from there.
Either way when the Reed Switch closes when made by the magnet you should hear a tone when the meter is set to tone.
The reed switch is part of the harness, which runs from the front of the drawer inside the cabinet to the main PCB, where it terminates.

None of this is true ans we have no service info even in the service manual for WD300CB.BBLEEUS
The information here was taken from Model: WD200 and is accurate for that model. We will look into WD300 and update the article soon. Thank you for pointing this out!
