Hi,
Check the lamp cooling fan of your projector one more time. may be its has some problem. its not running at the correct RPM. Do one thing, Remove the fan from the projector. In the fan there will be a specification sticker. Remove the sicker. now you can see a hole in the center. its the bearing part of the fan. put one drop of oil in it. u can use any type of lubricating oil. rotate the fan leafs with finger for some time. after that re-stick the spec sticker. insert the fan in the projector. power ON the projector and watch.
ok

Why does it run for a few minutes, then shut off?


Might be the fan, might need a lube but more likely to be a thermostat.

Ok So We Bought This. But We Have A Problem Does It Take Water Or Not? Thats What I Need To Know! Please Help!


The DeLonghi PACA120E Portable Air Conditioner quickly cools rooms up to 400 square feet and comes equipped with several functions that make operation easy and low maintenance. Its 3 operating modes are supplemented with no-drip technology, an adjustable thermostat, 24-hour timer, and much more. This unit truly takes the work out of cooling medium- to large-sized spaces. Multiple Modes and Functions The DeLonghi A120E-also known as the Delonghi Pinguino PAC A120E-offers 3 operating modes and 3 additional operating functions that make this model versatile and energy efficient. Cool Mode: 12,000 BTUs of cooling power help cool large rooms, offices, or basements. Dry Mode: Reduce room humidity by removing excess moisture from the air. Fan Mode: Circulate air to keep your room comfortable without using a lot of energy. Low, medium, high, and an auto-speed are all included (auto speed selects a fan speed for you). Smart Function: Your AC uses Cool and Fan mode based on ambient room temperature. This function will also select your fan speed and keeps your room comfortable without wasting energy. Sleep Function: Using a low fan speed, the AC gradually reduces operation so your room remains comfortable but the AC runs more quietly and efficiently while you sleep. Boost Function: This function is ideal for the summer months and uses the maximum fan speed to rapidly reduce your room temperature. Useful Features Using DeLonghi's patented no-drip technology, this unit is "dripless" under normal conditions, meaning the AC will discharge all of the moisture collected from the air-so you typically won't have to worry about draining the water. When dehumidifying a lot of moisture in Dry mode, excess water may collect in the internal collection tank. Once the tank is full, the air conditioner will automatically turn off to avoid overflow damage. You can also use the included continuous drain hose as a no-fuss way to eliminate excess water as needed. An adjustable thermostat provides additional convenience by allowing you to set your room temperature. The DeLonghi portable AC will cycle on and off to eliminate over-cooling and maintain the set temperature. Additional Features Washable Air Filter: A washable air filter helps remove allergens and other particles from incoming air and saves you money on replacement filters. Quiet Operation: High efficiency compressor and components result in quiet performance. Electronic Controls: The LCD screen displays the timer and temperature settings, while intuitive indicator lights accompany each operating mode. 24-Hour Timer: This feature lets you program your AC to turn on or off up to 24 hours in advance, so it only runs when needed. Window Bracket: Double window bracket is included with purchase for flexible installation. Self-Diagnosis System: The unit includes a self-diagnostic maintenance system that identifies malfunctions should they occur. Remote Control: Use the full-featured remote control to change modes, set the timer, and select a fan speed up to 23 feet away from the receiver (on the front of the unit). Portability: Easy-roll casters and dual carrying handles make it simple to move this model from space to space.

My 1986 Toyota Corolla overheats in traffic it has a brand new radiator and a brand new battery, I changed the coolant and oil, and it still overheats??


Is the radiator fan operating full speed when it overheats? If so inspect your radiator hoses to see if one of them has collapsed and gone flat.

If the radiator fan is not operating then possibly a relay or fuse has blown in the supply, or your engine temperature sensor has failed.

If fan and hoses are OK it is probable your thermostat has failed in the closed position.

What would cause my aspire 5630 to shut down sporadically?


Shut down sporadically, caused by rising temperatures on the processor (processor overheat). Processor overheat, caused by damage to the processor fan. Processor fan function to reduce the processor temperature.

Possibilities and solutions
1. The possibility of sluggish processor fan. Processor fan spins, with a low speed, so it can not reduce the processor temperature.
Solution: clean the processor fan with a vacuum cleaner, or replace the processor fan.
2. The possibility of fan processor die.
Solution: replace the processor fan.

The characteristics of damage to the processor fan
After the laptop is turned off (more than 1 hour), the laptop can turn on and survive + - 30 minutes. In the period of + - 30 minutes, the laptop died suddenly, because the processor temperature exceeds safe limits (shut down temperature).

How to check
Laptop is turned off (more than 1 hour), then turn on. Download and install software to check the processor temperature. Ex. Real Temp 3.60. See the change in temperature. If the temperature continues to rise, it can certainly cause damage to the processor fan.
- Normal temperature, when first turned on + - 38oC
- Normal temperature, after turn on for hours 40oC - 45oC
- Temperature overheat processor, when first turned on 60oC - 65oC

Acer z5610 suddenly turns OFF Temperature is normal, no overheat, new thermal grease System scanned for errors, viruses - nothing WHAT DOES IT MEAN?


Are you sure the temperatures are ok? When I run DIVX Plus Converter on the Z5610 the CPU (intel Q8200) is running (naturally) at a high load. Speed Fan 4.42 shows rising temperatures going north of 90 degrees C. If only DIVX Converter runs the temperatures of the CPU cores is around 92 to 94 degrees C. But if I start browsing the internet the temperatures go close to 100 degrees C. When one of the cores reaches 100 degrees C Speed Fan shows MINUS temperatures on the cores (-10 to - 20 deg C). Speed Fan is just monitoring as it can not even detect the Fan.
When that happens the Fan stops completely!! And short after that the computer switches of (same as if you would pull the plug).
Obviously there is a bug in the BIOS or the Motherboard which leads to interpretion of temperatures above 100 degrees C as MINUS temperatures which leads to the stop of the fan.
I am sure that also happens whenever you use a CPU intensive program (like a game or any other video converter/rendering program). You might download a temerature monitoring program (i.e. Speed Fan - its free) and see for yourself. Also listen whether the fan stops working compltely (goes completely silent) when the PC overheats and short before it switches off. Let's see what ACER says to that.
I used to like ACER. But first Aspire 4310 tripping frequently because the VGA chip overheats and now that stupid fault ==> never ever ACER again. I will use the Z5610 for internet surfing and get a real all-in-one which you can use. That is a clear sign for me that ACER does not test their machines at all under full load - or knowingly sells faulty machines.

Cooling fan intermittantly speeds up.


This is normal

Your fan speeds up and slows down in response to temperature inside the computer. More so the CPU.

I would suggest getting a can of compressed air made for computers

take it outside, take of the side and blow all the gunk out of there, Really go to town around the fan (you might want to wear eye protection)

Depending upon the way in which the lamp finally smoked, it is not unusual for the feeder fuse to blow. Replace the fuse and try the projector. As long as you haev a new lamp, it should work OK.

Soleus KFGHP-09-ID Mini Split


This is normal operation for these styles of minisplits. The thermostat is not in the remote but is located on the return air of the indoor coil, so the air needs to be flowing in order for the thermostat to measure the rooms temperature. Set your fan speed to auto and the fan will slow down when setpoint tempurature is met.
