Power Supply Connections

I replaced the fan inside the Power Supply and am trying to determine
the placement, if any, for the connector labelled "P9". It has 2 wires,
one black and one white. I may have inadvertantly disconnected while
working on the unit.

Not every wire that comes off the power supply is used so this might be worrying over nothing. I'd give a quick look at all your components inside- especially the cd or dvd players as well as the CPU fan. If it looks like everything is okay, power it up. When your system runs its POST (power on self test), it'll tell you if something critical is missing. If not, use it as normal. If something really is unplugged, later on you'll find out because it either won't work or a function of it won't work.

How to replace the condensor fan on GE Mod.gdl20kcsabs --bottom freezer


How To Replace the Condenser Fan The condenser fan is located behind the refrigerator. It may be necessary to remove an access panel to reach it.
If the fan blade is damaged, it can be removed from the fan motor and replaced separately.
Caution:Please read our safety information before attempting any testing or repairs.
cautiontri.gif Before replacing the condenser fan, unplug the refrigerator to avoid an electrical shock hazard.

The fan motor is held in place with screws and possibly a mounting bracket. Remove the bracket and the screws and pull the motor back away from the housing.
The fan motor is connected by two or three wires. Label the wire placement on the motor before disconnecting the wires. The wires are connected to the terminals with slip-on connectors or a plug. Firmly pull the connectors off of the terminals (do not pull on the wire). You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If the connectors are corroded they should be replaced.


Remove the fan blade from the old motor and install it onto the new motor. Connect the wires to the new motor and install the motor into the bracket or housing. Make certain that all of the screws are tightened securely.
Replace the access cover (if any) and plug in the refrigerator.

What to do if the fan of the power supply is not working?


yeah see if the power supply fan is not working the easiest alternative is to replace the power supply but if you don't want to change the full power supply all because of just a fan then in that case unplug the power supply and all its connectors connecting to sata drives,ide drives,motherboard,graphics cards,pci-express and all .Unscrew the supply from the cabinet/chasis and take it out 2.after you are done open it there are fine threaded screws on it,locate all of them on the surface and open them now when you are done take the cover off and after that,unscrew the fan from the front of the supply it has four screws,after that its wires will either be soldered to the board or will have a connector .you are really lucky if it has a connector just plug it out and install the new fan in its place and tighten the screws of the fan but if it is soldered then YOU SHOULD ONLY ATTEMPT SOLDERING IF YOU ARE GOOOD AT SOLDERING AS EXCESSIVE SOLDER APPLIED CAN SHORT CIRCUIT THE TERMINALS INSIDE THE SUPPLY AND RESULT IN FIRE AS VOLTAGE IS 110/220VOL IN MOST PARTS OF THE SUPPLY .Use a solder of 25watt or less as excess heating can damage delicate components inside also be sure to connect the new fan in correct polarity + and - .... after you are done just assemble it and connect the supply to the system plug in all wires ..your problem is solved without changing the supply :)

Faulty power supply or MOtherboard?


Test the Power Supply first.

If you have a multimeter, use the Positive (Red) probe lead to connect to the power wire to be checked.
The Negative (Black) lead connects to ANY ground wire. (ALL Black wires are Ground wires)

Three main voltages are produced by a personal computer Power Supply.
1) Orange insulated wires are 3.3 Volt
2) Red wires are 5 Volt
3) Yellow wires are 12 Volt.
(Again, ANY Black wire is a Ground wire)

Or use an economical power supply tester.
One example,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5250576&CatId=5471

You are making a connection from the green Soft Power On wire, to any Ground (Black) wire with that jumper wire.

Using an HP Pavilion A1330E desktop computer for an example,
we can see that the main power cable is a 24-pin ATX main power cable.

This is readily shown by looking at the motherboard,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00496280&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=1829044

Scroll down to the motherboard illustration, and the motherboard photo underneath the illustration.

This is the pin-out for a 24-pin ATX main power cable, and connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

The Green wire (Pin 16) is the Soft Power On wire. The other end of the jumper can touch ANY Black ground wire.

1) ALL the lights use less than 1 Watt of power.
2) EACH fan uses 2 to 3 Watts.
3) A typical Processor can use anywhere from 51 to 125 Watts. Depends on what Processor it is.

The three Processor options for the Pavilion A1330E are, (Socket 939 style),

A) AMD Athlon 64 X2 4800+
B) AMD Athlon 64 4000+
C) AMD Sempron 3200+

The Sempron 3200+ can use up to 62 Watts
Athlon 64 X2 4800+, 110 watts, and Athlon 64 4000+ can use up to 89 Watts.

Point?
You have nothing but the motherboard plugged in, and the Power Supply takes a 'nose dive'.
Power LED turns off.

Bad Electrolytic Capacitors in the Power Supply.
Replace power supply.

What causes this?
1) Most computer failure can be attributed to the inside of the computer is dirty, as well as the Power Supply.

When the cooling components of the Power Supply, (Fan, and internal Heatsinks), are clogged, the cooling capacity drops tremendously.

Heat = Wasted Energy

The Power Supply tries to keep up with the call for power, and eventually components inside the Power Supply fail.

A can of compressed air for computers, used on a regular basis as needed could prevent this. (Observe Anti-Static precautions Before placing hands inside computer)

2) Cheap quality power supply.
Saves the computer manufacturer money.

My ice maker and water stopped. Now all I get is a beeping noise when I try to use them.


Either the circuit is frozen, or filter is clogged, or circuit is faulty. You can test the circuit with an ohmmeter or voltmeter to determine if ther is power the unit.

Water is not dispensing from the inside water dispensr. new filter in place but still not working


HI. Check the line inside the unit to make sure it is not frozen, If you have confirmed that a frozen line is not the issue, move on to the inlet valve assembly.



The water inlet valve is located behind your refrigerator. Find the water supply line coming into the valve and turn it off at the source (typically under the sink). Disconnect the supply line. Remove the screws that secure the inlet valve in place.

The water inlet valve is connected by two wires. Label the wire placement on the water inlet valve before disconnecting the wires. The wires are connected to the terminals with slip on connectors

Firmly pull the connectors off of the terminals (do not pull on the wire). You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If the connectors are corroded they should be replaced.

Inspect the filter screen where the supply line connects. Remove any debris or deposits that may have built up using a toothbrush, or warm running water. If you cannot clear the clog, it will be necessary to replace the valve (the filter is not removable on most inlet valves).


Test the water inlet valve for continuity using a multimeter. Set the multimeter to the ohms setting X100 (if available, otherwise use the nearest ohm setting). Place a probe on each terminal. The multimeter should display a reading of 200 to 500 ohms. Close inspection of the inlet valve and especially the coil may reveal the exact ohm resistance rating to test for. If the water inlet valve does not pass this test, it should be replaced.

Hp pavilion 764c wire diagrams


Take a picture of the inside of your computer and put it up on the website with the wire connectors that need to be connected. The connecting wires should be in four groups. 1. The power supply connectors. These connectors will supply power to to all the power using components not supplied power by the motherboard itself. 2 The connections to the other components in your system like the dvd/cd player and the harddrive and floppy drive.3. The motherboard connections for the case. The power switch connector andreset switchconnector. The power led and theharddrive activity light.The USB connector and the audio connector.The fan connections like the cpu fan and other fan only connectors found on the motherboard.The external fans ( Fans that need to be connected to the power supply).Most of these connections are labeled on the motherboard. The case connectors also should be labeled for the correct connection. The best way to find the answers to this hook-up, may be to call HP pavilion with your computer make and model number,motherboard model number including revisions number. Computer made by big manufacturers tend to have may revisions and the only way to make sure your are getting a correct hook-up to the motherboard is call them for assistance.Especially if the motherboard and case labels are not present or so small that they cannot be read.Hope this helps you with your problem.

Motherboard fried?


the problem is your power supply, since the power supply have differrent output voltage there is 12volts, 3volts and so on. the 12volts output voltage is not giving enough power. you can determine this by detaching the 20pins from your motherboard coming from the power supply then power-on the power supply then use a jumper wire insulated but scraped both ends (conductor visible) then connect it to the green connector and the grey connector if the fan of the power supply doen't rotate then you 12volts output voltage is busted.

Fan not working?


You may have a bad Evaporator Fan Motor. You can check with an ohm meter. Caution: Please read our safety information Before working on your appliance, unplug the appliance to avoid an electrical shock hazard. The evaporator fan is located at the back of the freezer. It will be necessary to remove back inside panel of the freezer. Remove any screws that secure the back panel. Next remove any screws that secure the fan or fan housing so that you can access the fan's wiring. Label the wire placement on the fan before disconnecting the wires. Pull the connector off of the fan's terminal. You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors for corrosion. If the connectors are corroded they should be cleaned or replaced. Remove the fan blade from the old motor and place it onto the new fan motor. The Fan blade may slip off the motor shaft. Or the blade may have a spring or "C" clip. Use a slotted screwdriver to pry off the clip Replace the fan onto the mounting bracket and back into the fan housing. Spin the fan to make certain it can turn freely. Replace the rear freezer panel and plug in the appliance.
