For a detailed answer, read below

There could be several reasons why a garage door opener starts and stops intermittently. This issue can be frustrating and inconvenient, but it is not uncommon. Let’s delve into some possible causes and explore the topic in more detail.

  1. Malfunctioning sensor: One of the primary reasons for an intermittent start and stop of a garage door opener is a faulty sensor. The sensors are typically located near the bottom of the garage door tracks and are designed to detect obstructions in the path of the door. If there is an issue with the alignment, dirty lenses, or a faulty sensor, it can cause the opener to stop and reverse its movement.

  2. Motor problems: A malfunctioning or overheating motor can also contribute to the start and stop issue. Over time, the motor components may wear out, particularly if the opener is old or not properly maintained. Motor-related problems can result in inconsistent operation, leading to the opener starting and stopping unexpectedly.

  3. Remote control or wiring issues: Problems with the remote control or the wiring connecting the opener to the power source can cause intermittent operation. A damaged or malfunctioning remote control can send inconsistent signals to the opener, causing it to start and stop abruptly. Additionally, faulty wiring or loose connections can disrupt the power supply, resulting in inconsistent operation.

  4. Environmental factors: Certain environmental factors can also affect the performance of a garage door opener. Extreme temperatures, high humidity, or exposure to direct sunlight can impact the functioning of the opener’s components. For example, extreme cold can cause lubricants to thicken, affecting the smooth movement of the door.
