Having problems with your Air Conditioners ?

Our ac is not giving any cooling effect even after a long running time kindly suggest samsung AST18WJWDB

Answers :

You need to make sure that the unit is clean and all filters are clean. This includes the indoor coil and the outdoor coil. After cleaning, and still not cooling properly, check that the compressor is coming on. If not, check that the compressor is being told to come on by the thermostat by checking the voltage. If not, then its the control board to the unit. If so then check the leads on the compressor by doing an ohms test on each individual lead and a ground source. Ohms should read infinite. Then test between each lead. If you get a reading less than infinite, then the compressor is bad.

Ruud Silhouette II furnace: comes on and runs for as long as it wants, then turns off. Sometimes turns off at pre-set temp, other times just when it wants. May turn on again, behave well for several cycles, or for 20 minutes. When I get too cold, I go out, downstairs, and thump it near the fan. Starts right up, runs for as long as it chooses. Nearly least energy-efficient kind, v. frustrating. Had trouble-shooter out a few years ago, couldn't find anything. An intermittent short?

I have a 8 years old window ac. It's working quite ok. I just want to know which mode is safer low cool or high cool when humidity is high but temp. is about 32-34 degree celcius. Technican advised me to run in high cool mode for some time n then switch is off, but i want long hr. running in low cool mode which is quite comfortable. Kindly advise.

Its not a mater of safety. Its only a matter of witch is best for you. If you want to maintain the temp then leave it on low temp. If you want to save money then you can switch it to power saver mode on high to bring the temp down. Hope this helps. G ... Air Conditioners

Have a 5ton straight cool ac system. It's a Payne puron split sytem. metering device,txv. It will run for about 5 miutes during that time u can feel some cool back on the suction line. after that run time it will start to make a hissing noise. Over amp and shut off on internal overload. Any suggestions? Complete system is brand new and was put in around November.

Brand new systems won't require cleaning. Debris could get trapped inside the internal parts/lineset and break loose and cause a blockage which could cause high head pressure, hissing and over amp. It is possible that the charge requires readjustment ... Air Conditioners

A) I am trying to obtain a manual for a model #HWR12XC6-RB air conditioner. Can you send me one via email? B) Although it seem to run, the compressor only seems to run for a minute or two before shutting down for a time. Then it restarts. The temperature display seems to decrease while the compressor is running, and rises again when it is not running. The temperature never seems to aproach the set temperature.

Blower runs slowly if at all. Give it a spin or two by hand and it will slowly build up to full speed, RUN AND COOL AS NORMAL. But it only runs for a short time (12 to 15 minutes) then the blower slows down gradually then stops.

The fan bearings have become gummed up and will need to be replaced or cleaned. I am assuming yours is not a split type. If so you will need to remove the whole unit from its casing. Have a look at this link : http://dl.owneriq.net/2/2dca85dd-1 ... Fedders Air Conditioners

I have a 18000btu LG mini split heat pump installed about 1 year ago in vacation home. In heat mode the unit cycles on and off when room temp is within 2-3 degrees of set point.

During this time, I check inside temp with accurate digital themometer mounted at the air intake of the unit and the temp does not change, assume because unit does not run long enough.

My unit has never worked properly as it is dripping water and ruining my wall and my filters. The business that installed my unit is giving me the run around and ignoring my requests to fix my unit once and for all. They have been to my house multiple times with different "solutions" to this problem. The last time I was able to get anyone on the phone from Air Masters, the owner told me that he would replace my unit with a new one, but that you guys would not stand behind your product. Now,

My central ac system occasionally runs too long and the temperature gets way too cold. The digital thermostat reads that the temperature is too high so the ac still runs. This doesn't happen all the time but last night we had the thermostat set on 74 and when my wife got up during the night it was 67 degrees in the house (another thermometer read 67, the thermostat read 78)

I have seen this is many digital thermostats. The worst problems usually come from the touchscreen thermostats. I would suggest installing a new thermostat. Make sure that you read the instructions before you even remove the old one. ... Air Conditioners

AC will run for several hrs, cooling then just shut off. You can restart it & it may run but not long. I wonder if it has a float switch that is cutting it off. This is a new unit. First time used. I was told to make sure the camper was level.

Camper level should have nothing to do with it. When it shuts off, can you run it in fan only mode? Pull filter down from ceiling assy.,when this happens and let me know if you see frost on the coils up in that part of the AC. Get back to me. ... Dometic Rooftop RV Air Conditioner

I installed my attic fan about 10 years ago. Now, it will not start without me giving the blades a push. It hadn't been lubricated since installation. So I applied some 3-in-one oil. Still wouldn't start on it's own. Then I tried some WD-40 and it would start better. But then, not running overnight, again it wouldn't start without giving the blades a spin. Any suggestions?
