Compressor Failure Reasons

There are a variety of reasons why a compressors usually fails and I felt it would be a good idea to list and comment on the most common mechanical and electrical reasons for failure.

Electrical Reasons. 
Start winding Burn

This is one of the principle reasons why a lot of compressors fail and can be caused by a technician not wiring up the compressor properly. Other reasons why this failure occurs include:
- Wrongly sized or bad capacitor
- Loose or badly corroded terminals
- Compressor short-cycling
- Motor overloaded due to pressures not equalised
- Low voltage
- Compressor not turning
Run Winding Burn Out
A run winding burn out often appears as a general burnout due to the start winding getting burnt out also. The reasons associated with start winding burn out are very similar to a run winding failure..
Spot Burn

Spot Burn is usually caused by a surge in electrical current or voltage to the compressor. This is usually out of the technicians hands due to an electrical supply problem. A spike in voltage or current can result in arcing through the winding points of weaker insulation. A spot burn is a localised burn which can be within a winding, between windings or from winding to ground.

Mechanical Reasons

Liquid Floodback / Flooding
Liquid Floodback is when liquid refrigerant returns back to the compressor while running.  As we already know liquid cannot be compressed. The liquid refrigerant floodback will also dilute the compressor’s oil which causes pistons, cylinders and ring wear.

To prevent floodbacks happening an accumulator can be placed between the evaporator and the compressor which will catch any liquid refrigeration before accessing the compressor acting like a reservoir for any liquid.
Liquid Slugging
Liquid slugging is a condition which occurs when liquid is allowed to enter one or more of the compressor cylinders. Slugging can occur when moisture has entered the sealed system of from floodback problems mentioned above.
Because liquid is practically non-compressible, the compressor seals may be compromised when the pistons attempt to compress the liquid. Liquid slugging can lead to permanent valve damage and reduced compressor efficiency.

Low Compressor Oil
Compressors have moving parts and need oil to avoid seizure and overheating. The parts that compress the refrigerant vapour have to be lubricated and some oil always leaves the compressor with the refrigerant.
There is a certain amount of oil pumped out of the compressor with each stroke of the piston (usually 3% of discharged volume). The same amount of oil must return to oil-sump if the compressor is to be sufficiently lubricated. In a properly designed refrigeration system the oil travels along with refrigerant, completing the full circle.
The following can lead to lack of lubricant in the crankcase:

- Gas velocity too small to pick-up the oil:
- Due to lack of refrigerant in the system
- Due to oversized suction line
- Compressor short cycling
- Blockage in the system

High Discharge Temperatures
Occasionally discharge temperatures in a compressor can become so high oil can lose its viscosity for proper lubrication. This results are similar to having low oil where the parts that need lubrication start to wear out and become damaged. Evidence that this problem has occurred can include:
- Discoloured valve plate which can’t be rubbed clean
- Burned discharge valve reeds
- Burned and worn pistons, rings and cylinders
- Stator spot burn from metal debris.

In general, the biggest reasons for high discharge temperature are:
- High condensing pressures
- High system superheat
- Low suction pressures
- High compression ratios

How to Delete Undeleted File

"How to delete undeleted file?" or "How to delete unwanted programs?" etc. are the common question and queries when you failed to delete any unwanted file or program? Sometimes, it's really taugh to delete or remove unwanted program. The reason behind this type of situation is that a piece of adware or spyware continuously keep it busy and when you want to delete them, you get messages like the followings:

• Cannot delete YourFielNamefile: Access is denied.
• There has been a sharing violation.
• The source or destination file may be in use.
• The file is in use by another program or user.
• Make sure the disk is not full or write-protected and that the file is not currently in use.

This page will provide you to solve this type of problem. Keep reading...

Step 01:

• Click Start -> Search -> All Files and Folders
• Type the name of the undeletable file in the search box shown and lastly clickSearch.
• When you find the file or program, right click on that and go to Properties and make a note of the file location & close search window. It may be similar to :

c:\windows\system32\Name-of-undeleted-File.exe

Step 02:

• Click on Start -> Run -> type CMD  -> Press Enter to open a Command Prompt window.
• Don't close Command Prompt window, but proceed to close all other open programs. 

Step 03:

1. Click on Start -> Run -> type TASKMGR.EXE -> press Enter to start Task Manager -> Click on the Processes tab,
2. Click on the process named Explorer.exe and click End Process.
3. Minimize Task Manager but leave it open

Step 04:

1. Go back to Command Prompt window (step 2) and change to the directory where the file is located by using CD command. [ Example: to change to theWindows\System directory, write cd \windows\system32 and hit Enter]
2. Type DEL undeleted-filename Example: del undeleted-filename.exe. [undeleted-filename means the file or program you want to delete.]

Step 05:

1. Press ALT+TAB to go back to Task Manager
2. In Task Manager, click File -> New Task  -> Enter EXPLORER.EXE to restart the Windows shell.
3. Now, close the Task Manager

By follwoing these steps, you can easily delete any kinds of undeleted files or programs.

Moreowver, if you think that those setps are hard you may take help form any software like unlocker, Remove on Reboot Shell Extension etc.

Thanks....delete the undeleted files or programs....and smile...

How to force uninstall a program you cannot uninstall

At one point or another this happens to every computer user in the world: You install a program, find out that you don't like it, or need it, or that it's plain useless for the task you wanted to use it for, and you want to uninstall it. So you open up the Windows Add/Remove tool, click the button to uninstall the program... and find out that you cannot uninstall the program. In this article I will try to explain how to force uninstall a program, that you cannot uninstall using the Windows Add/Remove tool. Before that, however, I will try to explain what happens during installation.

What you need to know to uninstall a program manually

There are several things that happen during the installation of a program. First, of course, is the copying of files to the specified program folder (which is usually somewhere inside the Program Files folder). Also some files such as shared libraries (.dll files) can be copied into a folder inside Program Files called Common Files and some files such as drivers or shared libraries (again) are copied into the‘WINDOWS\System32' and ‘WINDOWS\System32\drivers' folders. After that the installer makes some changes inside the windows registry. The windows registry is a unified place where all the settings for programs and for windows itself are stored. The installer can make changes inside the registry for several reasons. For example if a shared library needs to be registered. Or if certain types of files need to be associated with the program being installed, so that the user could open them (e.g. if you install Microsoft Word, then you will be able to open Microsoft Word documents). After this is done, a key is added to the windows registry in a place where the Windows Add/Remove tool looks for installed programs. During the installation all these operations are logged in a special file (e.g. setup.log), and the installation program usually puts that file inside the application's folder along with the uninstaller. When a user tries to remove a program through the Add/Remove tool, windows looks for the registered uninstaller inside the registry, and executes it. The uninstaller goes through the log file and undoes all the changes done during installation. That is, it deletes all the files that have been copied, all the registry keys the installer created etc.

However, if there is no log file, or if there is no record of the changes made to the registry the uninstaller might fail to uninstall the program, and it will stay there untill it is removed by other means.

So if a program won't uninstall, how do you perform a force uninstall?

Well, if you know how to work with the windows registry, you probably can perform a manual force uninstall.

Before I go into detail about how to do this manually, I'd like to say that this is pretty advanced stuff, and if you're not a power user, then perhaps you should consider using specialized software such as the Perfect Uninstaller which allows you to do this in just a few clicks.

If you are a power user, then let's continue. First, let's see how to remove the program from the list of installed programs. To do that you need to open the registry browser:

1. Click Start and choose Run in the menu (If you're using Windows Vista then press Win+R on your keyboard).
2. Type regedit and hit Enter.
3. On the left side is the registry settings tree, use it to go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
4. Inside that key you'll find a lot of keys that belong to different programs. Some are named after the program's name, others as a mix of numbers and letters that makes no sense. Look through each of them until you find one that has the key DisplayName (on the right) with your program's name in it.
5. Notice the key UninstallString - this key points to the uninstall program, and the log file usually resides in the same folder as that program.
6. If you delete the key in which you've found the DisplayName key with the value equal to your program's name, then your program won't appear on the Add/Remove programs list.

Some programs create new entries in the registry to store their configuration options, these entries can usually be found in the HKEY_CURRENT_USER\Software or in HKEY_LOCAL_MACHINE\SOFTWARE - look for the program name or the name of the company that made the software. Don't delete Microsoft though - that contains Windows settings as well.

Next we have to find all the files that have been copied. Open the folder in which the uninstall program should be, and look for files which are named uninstal.log or setup.log or something similar. The list of files that have been installed is inside this file, you can open it in your notepad and find all of the files that have been copied onto your system. Delete the files and you'll get rid of the program almost fully.

Again, I'd like to stress that if you're new to the windows registry and all of this stuff, and if you don't feel like experimenting with your computer, then, again, please consider using either the Perfect Uninstaller or similar software, I do not want to be responsible for breaking your computer.
