Question about Medion MD-1768 PC Desktop

1 Answer

I blew the tower out with compressed air and replaced the thermal glue on the back of the proccessor. I also started to remove the front cover, but then decided to put it back on.. it didn't want to go back on and took a bit of elbow grease to snap back on. Now the power button blinks rapidly with the fan running low when I apply power to the tower. any help or suggestions would be appreciated

    Computer unplugged from power. Check for pinched wires by that Front Panel. Also I hope you cleaned the top of the Processor's case, and the bottom of the Heatsink THOROUGHLY, (Not shouting), before reapplying thermal Paste. (I hope it isn't thermal glue!) I use an old plastic credit card, and Q-tips with Isopropyl Alcohol, (Rubbing alcohol. CAUTION - FLAMMABLE!), to scrape the Processor, and Heatsink clean, then follow with the Q-tips/Alcohol. Make sure the Heatsink is sitting flat on the Processor. Three screws tight, and one loose will cause problems. Using clips to hold the heatsink on, finesse has to be used as the Heatsink could be tilted off to one side, if one clip is snapped into place, then the other. Best method is to snap both clips in place simultaneously. Using TOO much thermal paste can be as detrimental, as using no thermal paste. When the Processor heats up to normal working temperature, the excess thermal paste will ooze out, and make it's way down to the pins of the Processor, and any exposed solder joints. If by chance a thermal pad was used, never reuse it. Thermal pads are junk anyway, toss it in the trashcan, use thermal paste. Thermal glue is not a good idea, because the next time you want to replace the thermal media, the Heatsink will be glued to the top of the Processor case. Generally you have to use a hairdryer on low heat, (Moving back, and forth), to get the glue to soften enough so you can GENTLY twist the Heatsink sideways, back and forth, to remove it. NO FUN! Puts sweat beads on your forehead. I hope you observed anti-Static precautions, when you went to replace the thermal substance.

Have a GFSF6KEXAWW and would like advice on cleaning the coils. Do I need to remove the back cover?

Yes ,remove the back and front cover and use a well direct burst of compressed air to clean the coils. You can use a brush, but the best cleaning method can only be effected with compressed air.

Cycle stops and F35 displays flashing

I blew mine out with compressed air and it worked, You have to take the cover off and remove the small rubber hose. Then blow out the hose and blow into the small hole on the sensor. It is easy to remove from the machine, 3 screws in the back then remove the rubber hose, twist the unit so the bottom is facing the back of the washer and it pops right out, then remove the wire plug.

Did you clean the exhaust from the wall behind your dryer to the outside. This is more important than the dryer exhaust system itself. If not get behind dryer and remove exhaust to the wall and using a leaf blower,(electric) put it inside house vent then push dryer back to hold in place go outside and watch to see what all blows out. Good luck.

If ventilating helps, check that the vents on the bottom and where the fan blows out warn air are'nt blocked, try gently hoovering around area witha nozzle.
