My receiver has a broken main volume control knob and I use a remote for this. However sometimes when reducing or increasing volume there is a sudden burst of volume, ie it increases automatically to the maximum.
Volume of the centre and surround channels plays at maximum even though you reduce it to minimum. I have since stopped connecting any speaker to these channels.
What could be the cause?

No, I don't think there is a motor that is supposed to turn the volume - I think the volume is a push button type with one button to increase and another for down that is pushed by a clever rotary mechanism or if it isn't exactly like that the principle is probably a similar use of pure electronics.
It is clear the link between the infrared receiver and decoder and the volume electronics is broken and it will probably need a service engineer to discover where and effect a repair.
Unless the system has some kind of automatic volume control on it, that can only be adjusted by the remote. I think you might have a faulty volume/tone control circuit. These days many amps have a single IC that will control the volume. If that goes the volume can get stuck on one level. Since the control knob you are turning is simply sending a signal to that IC. So if the IC has died the signal is not being received.
If you want to repair it yourself just follow the wires back to the board from the volume control. You should see a large multi pin black box that if your lucky is marked on the board volume control.
Check your owners manual for "factory reset" this will reset the main micro-processor. Otherwise the encoder (volume pot) needs cleaning, soldering or replacement. It could also be a cracked circuit board (if it has recently been hit)
It sounds like the volume control pod has gone bad and needs replaced (The knob shaft connects to the pod main body and the inside of the volume pod is what controls the rate of volume,If the inside becomes worn ,broken or dirty the volume will become erratic) Replace volume pod ! ..You may try cleaning by taking off the volume knob and getting a can of pressure air and blowing the dust out!
Please rate response!!
I located the remote control for the unit and it works fine. As the unit is not the primary amplifier for the home stereo system, I use the remote to control the volume. Thank you for your quick responce, and I will keep you in mind for any future needs.
Unfortunately, it sounds as if the encoder is broken. The encoder is a digital input which takes the place of a traditional volume control, and is what holds the volume knob in place and spins. Since it works fine with the remote, that means everything else is ok, but you will have to replace, or have a tech replace, the encoder itself.
Can I ask you something? I have the same but the remote doesn't work, and I have no sound in the B speakers. I wonder if there's something that I have to do with the remote, or there's a problem with the receiver, Thanks.
