Milnor Washer-Extractor Message: A/D Board Is Not Talking

What does Milnor A/D BOARD IS NOT TALKING mean?

The E-P Plus control on Milnor H_J, V_J, X_J and MWR_ washer-extractors, such as the 36026X8J, depends on an analog-to-digital board, the A/D board, to read signals like temperatures and water levels. The board turns those signals into numbers the microprocessor can use. The microprocessor and the board are in constant contact, and when that contact fails the control posts the message A/D BOARD IS NOT TALKING. Without the board the controller is blind to the readings it needs, so the washer stops instead of running a wash it cannot monitor. The manual points to four places: the ribbon cable between the processor and the A/D board, the A/D board itself, the connectors, and power to the boards. A ribbon cable that has worked loose after years of vibration is a classic cause. Because the work involves the controller cabinet and requires locking off power, it is a job for a technician. The operator should switch the washer off and keep it out of service.

Affected models and control systems

This applies to Milnor washer-extractors with the E-P Plus control on the H_J, V_J, X_J and MWR_ models, such as the 36026X8J. Other Milnor controls use different messages.

Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

What you may notice

• A/D BOARD IS NOT TALKING on the display
• Washer stops and will not start a cycle
• No temperature or level readings available

Possible causes

Listed in Milnor's documentation

• Ribbon cable between processor and A/D board
• A/D board
• Connectors
• Power to the boards

Other likely causes — what usually sits behind A/D BOARD IS NOT TALKING on this control. A technician confirms which one it is before any part is replaced.

• Ribbon cable shaken loose by years of machine vibration
• Board power supply sagging after a laundry room power event
• Moisture or lint on the board connectors

Safe checks before calling for service

How a technician diagnoses A/D BOARD IS NOT TALKING

1. Read the message and note the washer model and control version.
2. Lock out and tag out power to the machine.
3. Inspect the ribbon cable seating at both ends.
4. Check the connectors for lint, moisture or damage.
5. Measure power to the boards.
6. Replace the cable or board only after the test.

How A/D BOARD IS NOT TALKING differs from similar codes

This message is about communication between the boards, unlike messages that name a single sensor or door.
