What triggers Door Open 5M
A door on the cabinet has not been seen as shut for more than five minutes, so the control raises Door Open 5M. The display may add a side letter: L Door Open 5M, R Door Open 5M or (L) (R) Door Open 5M.
Which side is L and R
DWR and ZWC models: L is the top zone or drawer, R is the bottom zone or drawer.
U-3036BVWCS-00B: the 3036 dual-zone unit uses the same L and R convention.
Single-zone units do not use the indicators.
What the owner can do
Verify that the door is closed and sealing.
If the message persists, contact Customer Care.
On the technician’s list
Check that the door closes properly.
Look at the cable arm, then confirm the magnet is there and that the arm moves correctly.
Inspect the wiring of the reed switch.
Codes to compare
Temp Hi 6H+ shares the same door advice, but concerns a zone running warm.
Evap T Open is a sensor-circuit message that appears in the same table.
No Comm means the unit lost its link to the display.
