Litter Robot motor and circuit board

My litter robot stopped working. The red flashing light comes on when the switched is turned on. I replaced the motor and circuit board in the Litter Robot Tm with the circuit board and motor I just bought from you. The red flashing light came and stays on. Any recommendations?

Hi,
we believe that we have already answered you in our support center.

But the red light issue is mostly related to the sensors of the machine, we suggest you test the Cat Sensor firtst.
