- Testing the safety reverse
What moves it
Why two quotes differ
| Factor | What it does to the number |
|---|---|
| Brand | Sensors are not universal. A pair matched to your opener is the only thing worth fitting. |
| The wiring | The two-core wire is stapled along the wall and is easily nicked. A new run adds a little labour and is usually the actual fault. |
| Whether it is the sensors at all | A blinking sensor is a symptom. Alignment, sunlight and a damaged wire all produce it, and none of them needs a new part. |
