Runs doesn't cool
Where is the air filter for the ruud ( #uak037jaz) air conditioner
Hi, Give the first unit about 15 minuets and try it again. The pressures have to equalize it the system before it will restart each time the compressor kicks off. The second one sounds like its doing what it needs to do. There should be water on the fins but no ice.\015\012Hope this helps.\015\012kstfas

This is a heating and cooling through the wall heat pump. It works normally when heating is selected - the heat pump runs and both speeds of the fan blow warm air. But nothing runs when cooling is selected. In other words the unit works normally when "High Heat" or "Low Heat" is selected but nothing runs when "High Cool", "Low Cool" or "Fan Only" is selected. The position of the Fan Cycle Switch has no effect - behavior of the unit is the same in both positions of the Fan Cycle Switch.

Fedders Model No. A7U12W2A-A, 12000btu airconditioner. The unit has been cooling satisfactorily for two to three years. Today the unit was cooling and suddenly there were a couple of reasonably loud knocks and the compressor stopped cooling. The fan continues to run. In about five minutes the cooling comes back on. The compressor runs for abut four minutes and shuts down. Earlier today we had a power dip without losing all power.
Hi, the power dip when translated means low current actually affected the relay starter which is situated beside the compressor. Now the relay starter works and stop intermittently which is why the Compressor cools whenever it works and does not cool ... Fedders Air Conditioners
Air conditioner runs for a few hours and it works - it cools the house. Then it stops cooling - the fan still runs but it doesn't blow out cool air any more. It seems like it's overheating or something. It will blow out cool air if it has not been turned on in a while but once it's on too long it stops. I was told it could be the fan motor and the a/c guy changed the fan motor today but that didn't fix the problem. Now he says it might be the compressor or that I need a new system. I'm jus

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

19 seer infiniti system, system will run for 2 mins. and then cut off and it will not show a code to the outside unit board or the thermostat. Replaced the thermostat and the outside low voltage wiring, then went to test mode on thermostat. Turned high cooling for 15 mins, it will run for 10 mins and then cuts off. It still does not show a code. If you go to the thermostat and turn it off, and reset it to cooling it will run for 2 mins and will cut off.
This cut off is very likely being caused by a defective compressor module thermo limiter (prevents overheating the compressor), replace it. ... Air Conditioners
1994 corolla-I charged the air cond., and it was cooling fine. After about a mo., it was not cooling very good. I assumed it had a small leak. I put my guages on it and the low pressure was running 15 to 20. The high side was reading about 150.I put a can of stopleak and detector in it. Then I put a can of freon in it. While I was putting the freon in it the pressure started to drop on both the low side and high side. Now the low side pressure is running about 15 and the high side is running 0.W
Hi\015\012\015\012\015\012Thanks for using FixYa. This has happened because of the low side pressure on your AC pump isn't kicking on, because when the pump is off, the pressures equal out and the low side shows a high ... Air Conditioners
1996 Coleman Model 7333C8876. Have 2 units on our Motor Home one day it was hot so I had both units running controlled by a Electronic Climate Control system. It got cool in the evening so I turned them off. The next day when i fired them both up on high the rear was fine. But the front will only cool on Low. The fan will not run on high and you can hear a slight noise coming from the unit. But the fan will not run on high.

I also forgot to add in my last question that when its dry the AC will run cool and we are able to get the house down to 82the degrees. Only when it's humid does it not work right. Its not always cool usually when everyone is home we run it its usually over 100the and we kick it on to82 it will cool the house down then when it kicks off it blows room temperature after that.
In dry mode the compressor on and off frequently. If you want full comfort keep it in cool mode. ... Air Conditioners
A/c will not continue to cool.. Starts fine, runs fine.. but shuts down cooling ( comp shuts off but fan still runs) after anywhere from 5 min to multiple hours. No circuit breakers or fuses blow. CAN usually reset by cycling wall thermostat if that does not work can unplug 12v. connection to thermostat and it will most often start cooling again when asking via the thermostat.

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

Carrier thermostat Hello, My Carrier electronic thermostat is connected to a heat pump. It was set to the COOL position during a summer thunderstorm when the AC suddenly began running no matter what the SET temperature was. It works normally when I change it to the AUTO position. The HEAT and EHEAT positions work normally. I tried cutting power to the unit for 2 days, after which it worked normally even on COOL, but after a short power failure it resumed the problem of running the AC continuo
