U-Line Ice Maker Error Code R Door Open 5M

This error means the right door switch has been in the open state for more than five minutes continuously. The unit uses a cable arm with a magnet to signal door closure to a magnetic reed switch. When that signal is absent for over five minutes, the alert is triggered. The cause may be a door that is not fully closed, a displaced arm or magnet, or a failed switch.

A power reset may clear the displayed error temporarily, but the code will return if the underlying cause has not been corrected. The unit must be able to confirm a closed door through the switch and magnet system before the fault stays resolved. Address the door closure, cable arm, and magnet first before attempting a reset.

If the fix is simply repositioning the cable arm or closing the door properly, there is no parts cost involved. Replacing a missing or damaged magnet component is generally a low-cost repair, typically in the range of a few dollars to around twenty dollars for the part. A door switch replacement, including a service call, could range from roughly seventy-five dollars to over two hundred dollars depending on your location and service provider.

Start by confirming the right door closes completely and the gasket seals against the cabinet on all sides. Then locate the cable arm inside the unit, verify it moves freely, and check that the magnet is still attached and properly seated on the arm. If the door and arm are both in good condition, the door switch may need to be tested and replaced.

Continuing to run the unit with this error active means the ice maker may not be operating the ice production cycle correctly, since door position affects machine operation. If the door is genuinely not sealing, warm air intrusion can affect ice quality and cause excess condensation or frost buildup. It is best to diagnose and correct the fault before resuming normal use.
