I can not switch the water temp on my kenmore elite front load washer


I don't know about your problem specifically, but my washer wouldn't click on. After I set the cycle and pushed start, it just clicked but not on. It turns out that the mother board wires have a loose connect at that particular spot. The service man, not a Sears since they couldn't make it there for a month, unplugged the machine, opened the lid (screws on the top back) and pulled out and re plugged some wires. When he tried to start it again, it worked perfectly. Occasionally it will do the same thing, so I UNPLUG the machine, take the back off and wiggle the wires (I know which ones they are by now), put the lid back on, plug in, and wala, she works.
Like I said, this doesn't address your problem specifically, but it seems the wires in the mother board tend to rattle loose. I hope this is an easy fix for you!! I was relieved. Sears may have sold me a new mother board at the tune of $??? That service call was a year ago and, although it is sometimes annoying, I haven't had to purchase any parts.

most likely the surge fried one of your ram chips... this is where i would start first sometimes the ram will work as a surge protection for your motherboard

My computer wont turn on


take out the psu completely from the cpu/tower, plug in the power cord,if there is a switch on the psu turn it on, next locate the main power connector (24pin) and find green wire,take a piece of wire and insert it into the green wire connector,next touch the other end of the wire to the psu outer case or a black wire on the main connector,if all is well the psu will turn on,if you have a dc voltage tester check the voltages on the red and black wires on molex connector...5vdc,yellow and black...12vdc.if ok look at the main board and inspect the capacitors to see if they are swollen, if ok
replace psu and disconnect hdd,cd/dvd,floppy ect from main board only leave memory,processor and video, power on if ok shut off and reconnect hdd, power on, if ok shutoff and connect floppy, if ok power off and connect cd/dvd drive.during this testing you will know what is bad.let me know how it turns out.email; arjoon.ken@gmail.com

MY PC WONT COME ON THE SCREEN IS BLACK


The mother board has a battery if thats the one you took out you reset the bios, Try pressing the delete simutanuosanly after turning on the computer then in the bios goto boot device priority and select your hard drive press f10 which is the save and exit. Try turning on your pc again and see if it boots off the hard drive make sure you give the computer time to re-boot itself after you change the setting in the bios.

OK. Thanks for the response. That message is telling us that the monitor is getting no signal from the computer. In your case, it sounds like it is working part of the time. So, here are the things that can cause the problem, starting with the monitor and working backwards.
1) The monitor may have an internal problem.
2) The cable connector that goes into the monitor may have a loose connection or be bad. Check for loose or bent pins in the connector plug and socket, and that the plug is seated properly and is tight.
3) The cable itself could be damaged and have a wire that is cut or pinched. Look for cuts or heavy crimps on the cable.
4) The cable connector that goes into the computer may have a loose connection or be bad. Check for loose or bent pins in the connector plug and socket, and that the plug is seated properly and is tight.
5) There could be a problem with the computer that is internal. If there is a video card that plugs into the mother board, you could unplug it, clean the dust and such from the contacts on the card and around where the video card plugs in the mother board and reinsert the video card. Also, the video card itself could be bad,in which case it would need to be replaced. Some systems have the video function as a part of the mother board. If that's the case, the mother board would need to be replaced.

One thing that you can try when it is failing. While watching the monitor, firmly wiggle the cable and each of the connectors to see if the signal comes and goes. You may want to enlist someone to watch while you wiggle, or wiggle while you watch (That sounds kind'a bad doesn't it? <Grin>) But, that could tell us something.

Hope this helps and will be waiting to hear back from you on this.

If computer is not powering on then open u r cpu and check the SMPS i.e Switch mode power supply which converts AC to DC it gives a output of 5v & 12v in that the 20 pin or 24 pin connector which is connected to the mother board remove that and short the wires Green and Black and make sure to remove all the power connectors i.e,hard disk,Cdrom or cd writer or DVD writer or any other device and one more connecto which is a four pin connector which is connected to the mother board please remove and test the 20 or 24 pin connector by shorting green and black and behind the smps u have a power cord of ac 220v just plug it and switch on if smps fan rotates that means it's fine then the problem willbe on the mother board just try this

Power Green Light Flashing HP Desk Top PC m7250n


During a power outage their is a surge when power come back on the grid (surge can be caused by lighting strikes akso). This surge trips the internal procters inside the power supply to protect the Mother Board, hard drive, processor and fans and any device that pulls wattage from the power supply. Since all these power using devices are trying to pull power at the same time to boot the computer back up one ends up with a loop of surge thrugh the power supply with a protective trip, reset, surge again and trip again. This will continue in this loop as the computer is trying to boot all the devices at one time (Mobo, Hd, processor, cooling fans and other devices). Simoly, more power wattage is being demanded than the protectors will allow at one time causing a protective shutdown followed by a restart followe by a protective shutdown in a continious loop.
The normall sequence for a boot is to boot the board, processor and fans followed by a boot of the hard drive, and other boot devices once the board is energised, NOT all devices at the same time, as this results in an overload and trips the protectors. This protective loop is indicated by the blinking light as the power is turned on and then shut down for protection as the wattage pull is over the demand that the protectors will allow.
Blinking light indictes you are in the protective loop.
SOLUTION: 1. Disconnect the Mother Board connector, with the computer unplugged, this will allow the power supply to reset at maximum wattage upon reboot.
2. Disconnect the Hard Drive power connector and ay boot device power supply cables, this will allow the Mother Board, processors and fans to boot without an overload of the protector inside the power supply.
3. Plug in the computer and the indicator light will be solid green indicating that it is reset and out of the loop.
4. With the computer pluged in and the Power Supply fully energised, plug in the Mother Board. The computer will now boot, and the processor fan will come on and the cooling fans.
5. After computer has rebooted, shut the computer back down and connect the Hard Drive power cable and any other power cablis that were unplugged.
6. Reboot with all cables connected and you are up and running again.

POWER SUPPLIES HAVE AN INDICATOR LIGHT FOR A REASON.
REMBER - BLINKING LIGHT IS AN OVERLOAD OF THE PROTECTORS AND ELLIMINATING THE OVERLOAD SOLVES THE PROBLEM AND THAT THE POWER SUPPLY IS WORKING AND CONVERTING POWER.
NO LIGHT MEANS NO POWER OUTPUT AND THAT INDICATES THE POWER SUPPLY IS NOT FUNCTIONING AND NEEDS REPLACED.

Hope this helps everone with power outages and lightining strikes. It is a rather common problem and can also occure when building a computer and one missmatches the power supply with the board wattage needs. If the board wattage needs are greater than the power supply output you will get stuck in a potective loop eventually. WHEN BUILDING A COMPUTER ALWAYS MAKE SURE THE POWER SUPPLY CAN PRODUCE MORE WATTAGE THAN YOU CAN CONSUME AT THE MAXAMUM LOAD.
Have a great computing experiense.
