Error code Door Open 5M
Appliance Wine Storage
Quick answer

Door Open 5M means the left or right door switch has been open for more than 5 minutes.

Model compatibility: U-Line reuses codes across series and model years, so Door Open 5M may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

Door Open 5M means the left or right door switch is open for more than 5 minutes; verify the door is closed and sealing.

If your U-Line dual-zone cabinet shows Door Open 5M, one of its doors has not registered as closed for more than 5 minutes.

Left, right and models

You may see it as L Door Open 5M or R Door Open 5M. On the DWR and ZWC models L is the top zone or drawer and R is the bottom one. The U-3036BVWCS-00B follows the same convention, while single zone models do not use the indicators.

Owner steps from the manual

  1. Verify the door is closed and sealing.
  2. If the message persists, contact Customer Care.

What a technician checks

A technician verifies the door closes properly, inspects the cable arm, confirms the magnet is present and that the arm moves correctly, and inspects the reed switch wiring.

Related codes

  • Temp Hi 6H+, a warm zone over 6 hours, which gives the same door advice.
  • Evap T Open, a thermistor message that is easy to confuse with it on screen.
  • No Comm, lost communication with the display.
