What Door Open Alarm means on your Dacor refrigerator (dacor refrigerator door open alarm)
This is a SmartThings app alarm (and an audible chime on the unit), not an error code. It fires when a door has been open longer than the built-in time threshold, a straightforward and genuinely useful reminder feature rather than a diagnostic condition, in most cases.

Symptoms
Run your eye down this list and compare it with the refrigerator in front of you, because Door Open Alarm shares its symptoms with several other refrigerator problems.
- An audible chime sounds from the refrigerator after a door has been open for a set period.
- The SmartThings app shows a matching Door Open notification.
- The alarm normally stops as soon as the door is closed.
- The alarm may trigger repeatedly if the door is only partially closed.
Common causes
There is more than one road to Door Open Alarm on a Dacor refrigerator, and the list below walks them in the order a technician would on your refrigerator.
- Door genuinely left open — the most common and simplest cause, especially with a full refrigerator load or a busy kitchen.
- Door not closing fully — food packaging, a shelf, or a drawer blocking the door from seating completely.
- Worn gasket allowing the door to sit slightly ajar — a seal that no longer holds the door flush.
- Failed or misaligned door switch — the switch that detects open/closed status is not reading the door’s actual position correctly.
Troubleshooting steps you can try
Start at the top and work down your refrigerator: the checks get progressively less likely, and the point at which they stop being safe for a refrigerator is marked.
- Check for anything blocking the door from closing fully, such as a package or bin edge.
- Confirm the door swings and latches normally without needing extra force.
- Inspect the gasket around the door perimeter for gaps or wear.
- Close the door firmly and confirm the alarm stops within a few seconds.
- Book a technician if the alarm keeps triggering with the door confirmed fully closed and unobstructed, since the door switch may need replacing.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the door switch, door gasket, hinge, and alarm speaker. The right part for your Dacor refrigerator is matched from its model and serial number, and confirming which component failed keeps the refrigerator repair to what it actually needs.
When to call a technician
This is a low-severity convenience feature; a technician is only needed if the alarm triggers falsely with the door provably closed. There is no urgency at Low severity, yet a refrigerator that repeats Door Open Alarm after these checks deserves a technician’s eyes. The technicians who will see your refrigerator are ours, not Dacor’s, and their labor is covered for 30 days.
