Adaptec 3405 making continuous noise RAID5 is configured on this. Observation :- This thing was observer first 4 days back when there was a power cut(I got UPS in place for power backup). Then i removed the card from its slot and re-installed in to the same slot and run ADAPTEC raid utility by Ctrl+a, the noice was gone. Again today it is making same kind of continuous noice, but this time there was no power issue. Please help me to solve this issue.

The belt tensioner bushing could be shot or there may be a piece missing from the belt. Did you check the back for a removable observation cover?

The compressor fittings may be loose and the mounting could have gone SOFT thereby making more vibration that radiates to the body and the plastic sections to make a larger noise.
You need to move the fridge forward and check the mountings of the compressor, the grills , the coils and the body . Switch on and observe the noise as the compressor runs and it will be possible to confirm with a good observation - use a good lamp to check for loose ends.

Hi.

It is an observation exercise where the observer has to follow specific parameters and to perform specific tasks, usually detailed in a written form or checklist.

If for example you do a guided observation of a teaching session you may be asked to base your evaluation of the lecturer on parameter such as:

Lecture structure.
Use of multimedia materials.
Time dedicated to pupil's questions.
Interactive activities.
Use of resources.
Inclusiveness.
Technical knowledge.
Professionalism.

The list of parameters written above will be the guide for the lecture's observation.

Regards.

Any noise must be identified with a good observation of the point of noise source.
This can be done with a good view with all safety precaution while the unit moves. Use good lighting and make sure that you are not putting your hands into any moving parts while the set works.
Now disconnect after observation and manually turn the drum, the motor and the rotor to fix the point of noise. this can be a faulty bearing assembly or a faulty suspension all of which will require a resetting/reassembly.

It all depends on the noise, the observation of the noise if coming from the outside or from within the engine.
Check your belts, fan, water pump bearings, pulley etc as the noise from the outside.
If this is inside noise you need to take opinion and estimate.

Turn your System OFF and put the Fan switch at your thermostat in the FAN or ON position. Allow it to run like this for 4 hours minimum. Before turning the system back on, ensure the air filter(s) and coils are clean. Also make sure all of the supply registers are open. All of these items affect airflow. Improper airflow is the number one cause of an iced up evaporator coil (as indicated by your observation of ice on the black hose). If, after doing all these things, you continue to have a problem, you most likely have a refrigerant problem (not enough or a restriction). This would require paying a CFC certified electrician to diagnose and repair. Try the air filters, coils, and registers first. :-)

either needs a new ignition relay or the wireing harness was not properly reconnected when the transmition was installed

My kawasaki has the same noise, specially when cold, but this should go off when your bike temp goes 1/4.thats my observation with my ZZR400
