Litter-Robot II Basic Troubleshooting Guide | RobotShop Community

@Clifford The motor connection should be; White+Brown and Green+Red. If it is like that, then we suggest you to verify the cat and safety line sensors, which would be triggered, having the Litter-Robot to turn the wrong way.

My LR2 stopped working, Iā€™m wondering if there is a problem with the power supply or where the cord attaches to the base

@Lemond Adams The problem can be caused by the power supply, the power jack or the circuit board. We suggest you to test the power supply with a voltmeter.

Tried the troubleshooting guide a few weeks ago and got the Litter Robot to cycle. It has stopped again with the yellow light staying on even after disconnecting power and checking/testing switches. Connections all seem to be good. Tested the gear for rotation and it does not regardless of effort. I am thinking it is the motor. Should I be able to manually rotate the drive gear?

If so, I guess I need a new motor.

@Kyle We do not recommend turning the gear manually. The problem you are experiencing seems to be caused by the motor, we would suggest you to replace it. You can purchase one here.

Our little robot is about 3 years old. It does not automatically cycle when the cat does his thing. It cycles fine when I cycle it manually. Does the sensor need to be replaced or do you think the sensitivity just needs to be adjusted?

@Jess Maybe the sensitivity needs to be adjusted. Verify the user manual at page 18 to help you with the adjustment. You can also remove the drawer and remove the black cover to reveal the cat sensor. Verify if the metal piece is still touching the cat sensor switch.

I replaced the circuit board and power supply todayā€¦ I put it back together and when I power on the unit I hear the motor engage and the yellow light comes on steadyā€¦ Then after a couple of minutes it starts flashing redā€¦ Thoughts?

@Scott Make sure you have installed the circuit board properly. Follow this guide for the installation. It is likely that you installed the wires the wrong way. Let us know how it goes

PERFECT! You were correctā€¦ one of the plugs backwardsā€¦ Thanks for the great support to solve my issuesā€¦

Iā€™ve had my Litter Robot for several years. Last year the motor went out, so I bought a new base unit. Now Iā€™m losing litter, and I canā€™t tell why or where itā€™s coming from. The unit seems to cycle just fine. But Iā€™m finding mounds of litter on the floor to the side of the unit. I donā€™t think that Iā€™m over-filling it. Besides, if that were the case, my cats would be tossing the litter out as they cover their messes. This is like litter leaked out while the globe was spinning. Btw, as I look at the unit, the litter is on the right hand side. Since the globe spins counter clockwise, itā€™s not coming out the openings on the side. I took the thing apart, gave it a good cleaning and even replaced the seal strips. Iā€™ve looked inside the globe to see if there was a tear in the lining, and it seems okay. But Iā€™m still finding litter outside and on the floor. Help! Do I need a new globe?

@Dyan We suggest you to press the cycle button and verify on the side of the unit if litter is coming from globe. If it is, you should see it coming out from the grate. It can also drop from the flap doors if the litter is sticking on it when the Litter-Robot is cycling.

I have a little robot to that is not cycling. Turn the power switch on it will start to cycle then all 3 lights flash. It does this even with the globe not on the base. Iā€™m guessing weak motor any thoughts?

@Craig Usually, this is the sign of a bad motor. We would suggest you to replace it, you can find one on our website.

The waste doors on the robot wonā€™t open at the end of the cycle. It goes through the whole process and just spins back around with the waste still inside. The doors are not stuck as I can open them manually without difficulty.

Waste port doors are not opening during cycle because peg on back of globe does not stick out far enough to engage.

@Robyn Unfortunately, you would need a new globe, which you can find here.

4 year old Litter Robot II.
The motor was struggling harder and harder over a few days. Not related to the amount of litter in the box.
Finally it stopped mid-cycle and didnā€™t turn ever again.

I ordered a replacement motor, swapped it out, now at power-up the yellow cycling light just flashes repeatedly, motor is not turning the globe. Iā€™ve left it for 4 or 5 minutes, no change. Took it apart, checked all connections, still same result.

I donā€™t see constant flashing yellow error light described in the manuals or troubleshooting guides. What to check next?

@Mathieu The motor you linked to says ā€œcompatible with Litter Robot IIā€ only. The front panel simply reads ā€œLitter Robot TMā€. How can I determine if it is a 1 or a 2? Thanks.
