What are the symptoms of a faulty door sensor?

[SanJayden]

There are two main symptoms of a damaged door sensor. Symptom 1 of a faulty door sensor: A malfunctioning door sensor can exhibit various symptoms, with the most noticeable being abnormal door operation. You may feel irregularities when opening or closing the door, such as excessive door opening angle, difficulty in opening, or the door automatically closing by itself. These issues may indicate that the door sensor has deteriorated over time, resulting in reduced limiting effectiveness. Symptom 2 of a faulty door sensor: Unusual noises when opening the door are another sign of a faulty door sensor, usually caused by lack of lubrication. If the door sensor remains unlubricated for extended periods, it becomes prone to wear and metal fatigue. For this problem, you can visit a repair shop to apply lubricant or purchase and spray it yourself.
