Werhoo 41A5034 Garage Door Safety Sensor Kit for Openers Made After 1997

If you need to replace a failed garage-door safety sensor, this kit is aimed at compatible LiftMaster, Chamberlain, and Craftsman openers made after 1997. If you are shopping for a different opener system or a MyQ-compatible part, the listed compatibility is an important distinction.

The Werhoo 41A5034 includes sending and receiving sensors, mounting hardware, wire connectors, and installation instructions. It is described as a compatible replacement, not an original-branded part.

Key features

The sensors create an invisible beam inside the garage door opening. When something interrupts that beam, the opener is designed to reverse the door, providing an obstruction-sensing function. The sending sensor has an amber LED and the receiving sensor has a green LED, which offer visual indicators during setup and operation.

Compatibility is listed for LiftMaster, Sears, Chamberlain, and Craftsman openers manufactured after 1997. The product information specifically excludes MyQ. It also lists several replacement references, including 820CB, G801CB-P, 2610459, 012381050345, 041A5034, 801CB, 41A5266-1, and 041-0136. These references help identify whether this is the type of sensor you need, but they do not establish compatibility with every opener.

Buyers commonly describe the kit as straightforward to install and report that it can fit existing brackets. Feedback is not uniformly positive: some buyers say the included wires are short, and others dislike where the LED indicators sit relative to the brackets. Those details may matter if the existing wiring or indicator visibility is a concern.

Best use cases

This kit is intended for replacing a safety sensor on a compatible garage-door opener, rather than adding a new feature to an opener that does not support this sensor type. It includes one sending sensor, one receiving sensor, wire connectors, wing nuts, round-head bolts, and installation instructions. The listed dimensions are 4.4 x 2.8 x 1.6 inches, and the weight is 3.2 ounces.

It’s a great fit if your opener matches the listed brands and manufacture date and you want a kit with both sensors and basic installation hardware. How much work will the replacement involve? That depends in part on the existing mounting and wiring, the included instructions and connectors are intended to support installation, but the listing does not specify wire length beyond mixed buyer feedback.

Practical tips

Confirm the opener’s make and manufacture date before choosing a replacement, and compare its existing sensor and wiring setup with the included parts. The product information says to disconnect power to the opener before installing the safety reversing sensor. Follow the supplied instructions, then check that the sensors are aligned and the door reverses when the beam is obstructed, using the opener’s own safety-check guidance.

If your current brackets are staying in place, buyer comments suggest the replacement may fit them. However, reports about LED placement differ from what some buyers expect, so consider whether indicator visibility will matter in your installation. You may want to skip it if you need a sensor explicitly compatible with MyQ, since this kit is listed as incompatible.

Practical questions

Which openers is it listed for? The listing names LiftMaster, Sears, Chamberlain, and Craftsman openers made after 1997. It does not claim compatibility with every model, and it excludes MyQ.

What comes in the package? The kit includes a sending sensor with an amber LED, a receiving sensor with a green LED, installation instructions, wire connectors, wing nuts, and round-head bolts.

Do the sensors use a visible beam? The product description says the beam is invisible. The LEDs are separate indicators on the sensors.

When it makes sense

Choose the Werhoo 41A5034 when you have a matching opener and need a replacement kit with both safety sensors and installation hardware in one package. Buyers often find installation and bracket fit manageable, but feedback flags short wires and LED placement as possible annoyances. If you are comparing it with an original-branded replacement, note that this is described as a compatible spare, prioritize matching the opener and the existing installation over the reference list alone.
