motor Help with motor

[Karen Moore]

The motors are not working and I don't know why. I have replaced the batteries and when turn on light is green but then turns red immediately. There is a constant bleeping sound. The cogs seem blocked... I am new to this so am hoping it is something easily fixed. Anyone know how? Any advice greatly appreciated. Thanks

It would help if you let us know which mount.
