Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Verify supply valve open

    Locate the water shutoff valve supplying the Maytag MIM and confirm it is fully open.

    Common oversight — valve turned off for service and not reopened.

  2. 2

    Check and replace water filter

    If the ice maker has a water filter, inspect for clogs or expiration. Replace if older than 6 months.

    Expired filters severely restrict flow.

When to Call a Professional

Contact a qualified technician if:

  • Fill valve coil reads infinite on multimeter
  • Water supply verified good but LO persists
  • Frozen or damaged supply line
