What DOOR Means
This alarm sounds at regular intervals when the door has been left open, or isn't sealing fully closed — interior temperature can begin climbing the longer it continues. Viking documents the pattern in the VUWC244DRSS service manual (2010, section 2.1.11, page 8): with the TruProtect system enabled the tone sounds three times every thirty seconds and an amber door message appears in the message center, and closing the door is what resets it.
Common Causes of DOOR
- Door genuinely isn't latched
- Something inside is preventing the door from sealing fully
- Door switch has failed and is reporting open even when closed
🔧 One Safe Check You Can Try
Check for a bottle, rack, or shelf liner pinching the door before assuming the door switch itself has failed.
