Re: noisy working
Have you checked the fan. I've had out of balance fan blades caused by a build up of dirt.
Remove fan blade and check the back of the center hub area for accumulated dirt.

Re: noisy working
I have just seen that Patrick Kotza in his book "REFREPAIR MANUAL", describes a situation that seems to be what you have.
If the slide on the 4-way valve sticks in some intermediate position, all 4 ports will be connected. This effectively short circuits the HP/LP, creating an unstable situation.
The vibration is the slide valve.
