Softener display is blank but outlet has power

Safety first: Unplug the transformer from the outlet before inspecting the control head.

Steps to check:

• 1. Test outlet: Plug another device into the outlet to confirm it has power.
• 2. Check transformer output: Use a multimeter to measure the low-voltage output of the Whirlpool transformer. Replace if no output.
• 3. Inspect connectors: Ensure the low-voltage plug is fully seated in the control head. Check for corrosion or damage.
• 4. Replace control board: If the transformer is good and connections are secure but the display remains blank, the control board is likely failed and must be replaced.

When to call a technician: If you are not comfortable testing electrical components, contact a professional.
