The short answer
This page covers a KitchenAid refrigerator that reports a door as open when it is visibly closed, or leaves the interior light on. That is the door switch or sensor rather than the gasket or the alignment, and the interior light is the fastest way to tell: a light that stays on with the door closed proves the appliance still thinks the door is open. The companion pages cover the gasket and alignment.
Causes, ranked for this Kitchenaid refrigerator
- Door switch stuck or dirty — Why: The switch is pressed thousands of times and gets sticky with spills and dust, so it holds in the open position while the door itself is perfectly shut.
- Magnet or sensor misaligned on the door — Why: Models using a magnetic sensor need the magnet in the door to line up with the sensor in the cabinet, and a door that has settled moves it out of range.
- Wiring chafed in the hinge loom — Why: The switch wiring flexes at every opening, so a conductor eventually chafes and produces an intermittent alarm that follows door movement rather than door position.
- A door genuinely not closing fully — Why: An overfilled bin or a sagged door leaves a real gap, in which case the alarm is correct and the companion pages cover the fix.
- Control board or its input — Why: Last, because a stuck switch and a misaligned magnet imitate it exactly and both are far cheaper to check.
What to check, in order
- watch the interior light as you close the door. — Because: a light that stays on proves the appliance still thinks the door is open.
- press each door switch by hand and feel whether it moves freely. — Because: a sticky switch is the top cause and it is felt rather than seen.
- confirm every door is genuinely fully closed with nothing in the way. — Because: a correct alarm on a real gap is a different problem entirely.
- note whether the alarm follows door movement or door position. — Because: movement points at chafed wiring; position points at the switch.
Checks you can safely do yourself
- Close each door slowly and watch the interior light, noting any door after which the light stays on. — Tools: none — Time: several minutes
- Press each visible door switch by hand and confirm it moves freely and returns, cleaning around it with a dry cloth. — Tools: a cloth — Time: several minutes
- Check nothing in a door bin or on a shelf is holding a door fractionally open, and empty the bins to be sure. — Tools: none — Time: several minutes
- Open and close each door repeatedly and note whether the alarm follows movement rather than position. — Tools: none — Time: several minutes
- Switch the unit off at the breaker briefly and restore it to see whether the alarm clears. Stop here: switches and hinge looms need metering. — Tools: none — Time: several minutes
Before you open anything
Safety

Kill power at the breaker before touching any wiring or removing a trim cover, and never chip frost inside with a metal tool. A door carrying a dispenser has water lines and wiring through its hinge, so never lift one off alone to inspect a loom.
Where the owner fix ends
Cleaning switches, emptying bins and observing the light are owner work. Call a technician when the alarm persists with a freely moving switch and fully closed doors, when it follows door movement rather than position, and when the compartment is warming because the appliance believes a door is open.
