Having problems with your Air Conditioners ?
Descktop computer turns on, but no video
Hi,\015\012I'm assuming your motherboard has a built-in video card. Let's trying doing it by the numbers.\015\0121. Remove all memories, cards, FDD, IDE or SATA cables from the motherboard. What should be left are only the power supply connector, the CPU + Heatsink & fan;\015\0122. With the unit off & unplugged, pry/remove the 3V memory battery. Short the CMOS reset jumper. This is normally located very near the battery. If you can post brand/model of MB, we can probably point the exact location or you can go to the manufacturer's website and download the pdf file of the manual;\015\0123. Leave it with no battery and the CMOS reset (not default) jumper in place. Give it a couple of minutes;\015\0124. Re-insert the battery and remove the jumper from reset position and replace it back to default position (its original position);\015\0125. Connect keyboard, power cord, monitor video cable (onboard video connector is below the printer port and beside the serial COM1 port) and;\015\0126. Power up. Most cases you will have a series or combinations of beeps since there is no memory (and no video since the onboard video uses shared memory). Sometimes no beeps at all. Power off;\015\0127. Install a single stick of memory. It would be a good idea to clean the edges/connector pins of the memory stick with the use of a pencil eraser. Further use a clean/new paintbruh to remove any other dirt. Use the same brush on the slot where the memory is to be placed. Seat the memory into one of the memory slots. Power up, there should now be a healthy pre-post beep (if you do not have an onboard video, a long beep will tell you that no video card present). If no beeps nor display in your monitor, power off, remove the memory and place it in the other memory slot and try again. If still a no go, try with another memory following the same sequence.\015\0128. If still a no go, try with your videocard either in AGP or PCI-E slot as applicable;\015\0129. If it works, you're set to re-install everything else;\015\01210. If not, your motherboard and/or processor has to be replaced.\015\012Hope this works out for you. Good luck and pls post again how things turn up. Kind regards.
From the symptom, it could be the main mother board faulty. the cost of mother board is about the same as the video card.hope it would help.

My air conditioner only goes for a few seconds then turned off by itself. the technician that i called on the phone said, ''It's probably caused by the unstable voltage from the electricity company.'' The other night, I found out that i had to turn off my computer first so i could get the aircon to work. After the aircon is running, i can turn on my computer without any problem to the aircon. (The aircon and my computer is on totally different outlet) But today, in the afternoon, even without my

I have a Lennox pulse 21 furnace. It will not turn on when I turn it to cool or heat. I checked the main computer module and the LED light is off. I had reset the furnace by using the switch next to the furnace, and this will not turn on the light. Is there anything else I need to check before I call a service tech to look at the main module? The switch to turn on and off the furnace with the removal of the bottom door may be bad. Is there anyway to check this?
The switch you are talking about can be checked. Turn power off to unit. Disconnect wires on both terminals of this door switch. Next use a meter that will show Ohms or just connectivity to see if switch is closed when pressed all the way in. You cou ... Air Conditioners

The heat pump is not working properly. i think the problem is in the switch mechanism. when the heat is on and the thermostat is turned up it blows cold air. sometimes the compressor turns on and off. if you turn the other switch to the off position, then turn the thermostat up then turn it back to heat. it will blow hot air. if you then turn the thermostat down, wait till it turns off, then turn it back up, it will blow room temp air and sometimes the compressor will turn on.

My panasonic cs-e12hkr airconditioner will only run for approx. 20 mins then always turns off and will not turn back on no matter how hot the room gets. I have the timer turned to off, but it still turns off after a short while every time. I checked for a fault code and got F95, with 18 beeps from the unit. It seems that the timer is set to run for 20 mins and will not alter or turn off. The timer shows 8.00 as a start time and no end time, even when turned to off.

Hi, I have a goldStar GA 1866VHR split Airconditioner, (5050w cooling and 5040w heating capacity). Today I noticed that compressor/condenser unit was still running after I turned off the aircond: from the remote control. The fan unit turned off as normal. I had to turn off the isolation switch to turn off the compressor/condenser unit. After about 2-3 hrs I turned on the isolation switch and the compressor/condenser unit came "on" stright away without the fan unit. Went inside and turned on fro

The bard geothermal (open loop) furnace will not produce heat. I will turn on the heat and the furnace will begin to turn on. The water will start to flow and then the furnace turns off.

My unit is 4 years old. I always turn it off when I leave for work in the am and turn it back on when I get home in the pm. Last night I turned it on at 7:30pm. When I went to the front of the house about 45 minutes later, I noticed the unit outside was trying to turn on but would immediately turn off. I checked the breakers in the garage, turned them off and back on but still had the same problem. The fan inside the house is running but unit outside will not kick on. I looked for a magic

I have an old samsung airconditioner (Arc-102) and when I turn it on, it turns itself off at random times. Sometimes it stays on for 2 mins and others times 30mins. When it turns off the timer light flashes. I have turned off the timer settings using the remote and it still turns itself off randomly. We have 2 of these aircons. The other works fine, and when I use its remote I still have the same problem.

Dometic roof top AC unit compressor turns on even if T-stat is off. Only way to get the compressor from turning on is to turn the breaker off. Unhooked T-stat wires to see if issue was there but the compressor still kicks on when I turn the breaker back on. If I leave the auto t-stat on, the compressor will turn on for a bit with a loud hum until after a couple minutes or more it shuts off with a loud thud that will shake the RV. Then after a while it will do it again. Only let it happen twice
Sounds like you may have a couple of problems there. First, have you checked incoming voltage to make sure you are getting 100-120 VAC at the AC control board in ceiling? If that's ok, try removing/disconnecting Ac compressor wire at ceiling control ... Dometic Rooftop RV Air Conditioner

I have a Fedders AZEY18F7B a/c unit. I want it to turn on at 7pm and off at 7am everyday automatically. The timer setup is stupid. It says something like, how many hours from now do you wnat it to turn on, and how many hours from now do you want it to turn off. It doesn't not turn on when I tell it to. And if it did do what I programmed it to do, the instructions don't even say if it will repeat everyday. How can I get this stupid timer to actually turn on my a/c at 7pm and off a

We have a new house and it came with central air. I have turned on the air and turned on the circuits and noticed that the outside fan on the outdoor unit was spinning round (good) now, I checked and the fan is not turning.

First check to be sure the circuit breaker for the outside unit is not tripped. Turn the two pole breaker all the way off all the way off and then back on. If the outside unit still does not run you may have fuses in a disconnect box by the outside ... Air Conditioners
My fedders aircon compressor does not turn on again whenever its thermostat turns it off. what i had to do is unplugged the power cord and turn it on again to work. i already replaced the capacitor. what i observed is that the big normally open rely does not switch on. maybe a board problem? if i turn it off and turn it on again, only the fan rotates and not the compressor. i had to unplug the power and put it back again for the compressor to run again.
You have a time delay build in on the pc board of 3 minutes. If it takes longer than 3 minutes check your compressor overload protector, Maybe the compressor is overheating, check your coils for proper air flow. ultimately if the compressor checks ok ... Fedders A6X05F2D Air Conditioner

At this point the heat will turn on but when the thermostat shuts down the system it will not turn back on when calling for heat unless I adjust the screw again. Also, the switch will only turn on the system when set at 5 on the dial on the inside. Any i
