A snapping sound often indicates a stretched transmission cable. In Cherwell, we replace these with steel-core timing belts that resist stretching. We also inspect the carriage wheels. Replacing worn rollers eliminates friction, allowing the door to glide effortlessly.
The powerhouse of your system in Cherwell is the High-Torque Drive Unit. When these fail, you might hear mechanical shuddering. We diagnose specific faults like encoder positioning errors and replace the unit with OEM parts to restore silent operation.
False activations, known as random cycling, are common in Cherwell due to weather interference. We calibrate Bea Eagle sensors to ignore interference. Crucially, we test the active infrared safety beams to ensure the door reverses upon obstruction.
