Any LR2 expert here? When my 7 years old LR2 stopped working, I decided to give it a tune up. I replaced the circuit board, motor, and power supply, gliders, among misc items. I verified that the power switch, cat sensor switch and motor connection are still working properly. To my surprise, the unit still won’t power up. The only thing I can’t electrically verify is the hall effect sensor. If the hall effect sensor is bad, would it stop the circuit board from powering up? I have spent about $150 already with nothing to show for, now I’m hesitate to replace the wiring hardness (which includes the sensor). Any help would be appreciated.

Hello @KevinK,

Welcome to RobotShop community.

We are sorry to hear that you are having trouble with your Litter-Robot.

Usually, the sensor harness gives an error regarding the position of the robot, however, in some rare cases, the robot would stop completely and doesn’t show any power.

Since you have already replaced all these parts, you should replace the sensor harness as well.

And check all the connections from the power adapter all the way to the circuit board to see if there’s any damaged or disconnected wire.

Let us know how it goes.

Sincerely,

I was adjusting my litter robot II and accidentally disassembled the entire foot sensor - spring and all. A second nut that fell out in addition to the ‘top’ nut and I can’t manage to get the foot assembly back together and working appropriately. I can’t figure where the second nut goes - if there are any diagrams or descriptions as to to how to assemble, I would greatly appreciate it.

Hello @footinmouth,

Welcome to RobotShop community.

We are sorry to hear that you are having trouble with your Litter-Robot.

Here’s a guide to show you how to assemble the CAT sensor again:

There are other guides for all the parts of the robot so you can follow them to locate the place where the other nut should be installed.

Let us know if you need further assistance.

thanks - it’s not the sensor I am struggling with but rather the trigger plate/spring loaded foot apparatus. There is a second nut that seems to lock the foot in place but I cannot get it to work again
