DURING DAYTIME WHEN HOT OUTSIDE 35-40 DEGREES C, AC TRIPs off

I am from India. Whole of the night My Window 1.5 T AC works efficiently but DURING DAYTIME WHEN IT IS HOT OUTSIDE 85-90 DEGREES C, Voltage suddenly drop down to 100 and it causes copressure to trip and some time mail MCB also. When again switch on the AC, comressure starts after 3 minutes delay but again after 5 to 10 minutes voltage (of the ac line only) starts drpping down to 100 or even lower and compressure and then MCB trip. One 1 T AC is also intalled on this powe line which works well. Thanks, AKS

Units are not able to work properly above 90, 1.0 T not go for more than 1 room. is outside of unit clean? if not turn off power to unit then spray 409 or simple green or something along those lines of cleaners on the coil part (soak it real good) it should cover entire coil as much as possible. let cleaner sit on it for about 10 minutes then use water hose to rinse as good as you can. wait about 10 minutes then try unit - so work better.

LGWHD1500ER 12 amp 15,000 btu Window a/c unit.


the condenser is in the hot sun and the fan that moves the air is not cooling or removing the heat from the condenser fins
This places the head pressure of the compressor too high and so the circuit breaker trips from the excessive current draw to run the compressor under this load
The answer to this problem is to place shade cloth on a frame which covers the air conditioner by placing it in a shady area
another solution is to replace it with a split system where the outside unit can be placed away from the sun

How to cool big home with small air conditioner(s)


A lot of people have only one or two rooms that can take an air conditioner in the window. Often times, the air conditioner is also rated at a cooling power that would make you believe that there is no way that it can to cool the whole house/apartment. You can crank it to the max to try to cool as much as possible, but then this makes one room too cold and the others still stay too hot. You can try blasting the cool air down a hallway with a fan on maximum speed, but that only works so well. And, it's noisy, too. Well, I have two 260 sqr ft rated room air conditioners and I am cooling 2000 sqr feet of house to a comfortable 72 degrees in all rooms and it's been 95 outside all day. How to do it?

The trick is setting up your home to take advantage of laminar air flow. Set your air conditioner to say 68 degrees and start it in the middle of the morning before it feels hot outside. Put the AC deflectors pointing downward and towards the door. Put fans in the doorways pointing out of the rooms that have the AC. Point them level to the floor (not up) and put a fan to one side near the end of long hallways. Set the fans on the lowest power setting (not high). If the hallway branches out into a bigger room, put a fan in the room that is blowing across at a right angle to the entry, pointing the air flow parallel to the wall. This will circulate the cool air around the room. Keep the fans on low and pointed parallel to the floor, not up!

What you have created is a re-circulating air flow system, much like the North Atlantic Current that moderates the temperatures of Europe. You can check this by taking a tissue paper and holding it up to the top of the doorway. The air flow should be pushing the tissue away from the room without the AC and toward the room with the AC. This happens because the warmest air will be toward the ceiling and you want that warm air to make its way across the ceilings and back to the room with the AC, so that it can be cooled again. The cooled air from the AC will sink to the floor and the fans will gently push the air out of the room with the AC. It will stay low and travel along the floor in the opposite direction and into the warmer rooms. If you crank your fans up, you will create turbulent flow and that will not cool your house as efficiently as will laminar flow. Monitor the outside temperature and when it gets cooler outside by a few degrees, turn the AC to fan for about 10 minutes to eek out the last of the cooling. Then open the windows for the night to take advantage of the free cooling that nature provides. That's it! Enjoy the summer!

Heat pump not keeping up to set temperature on thermostat but never drops below 63 degrees whens its 20 degrees outside.


It may be getting low on refrigerant due to a small leak. I'd have it serviced soon. When running at less than peak efficiency it will much more often switch on the heat strips and they are not cheap to operate.

SPLIT AC CONDENSER TRIPS AFTER 1 OR 2 MINS, ONLY DURING THE DAY TIME


The condensor is not cooling fast enough. Try cleaning the condensor coil. Also check that the fan goes on. At night the outside temperature is cooler and does not need much work to cool down the condensor.

Domestic a/c runs fine for hours then trips circuit breaker


Check the difference between your incoming voltages at these times, it may be, if your plugged in to park power, the voltage getting to you may be less due to neighbors using more. If you have a genny, try using it when this happens and see if it trips. More lights, TV's etc are probably being used at night by others.

AC not cooling during the day


Your AC cooling efficiency is low when he ambient temperature is high and naturally it cools well when the outside temperature drops.

Please remove the filter on the grill and try to clean it under the tap water and after removing all the dust fix it back to the unit. This would increase the cooling efficiency of the unit.

Your AC is also five years old. Please avoid frequent opening of doors or windows.

Ensure that the exhaust fan and the blower of your unit are functioning normal.

The technician might not have done a proper job in fixing the area where the refrigerant would have leaked out. Please check the refrigerant pressure to ensure that no further refrigerant leak has taken place. Or even servicing your unit he would have punchered the tubes resulting in very slow leak of refrigerant resulting in no cooling or less cooling. It takes around a month to feel the pinch of it and the refrigerant. One fine morning after sometime the unit will run and it would start throwing hot air instead of cool breeze!

579 series, 13.5K BTU Rooftop trips AC circuit breaker in hot weather...


Is your condensing unit located in a well ventilated area and have an ample space, atleast a foot, from the rooftop flooring? Just make a check that free flowing outside air properly ventilates the condensing unit specially on high ambient temperatures. Hope this would solve your problem

RV ROOF TOP AIR CONDITIONER TRIPS BREAKER


Possible low voltage condition would cause that kind of a problem. To small a cord without the ability to carry and maintain the voltage would cause a voltage drop. I would test the voltage supply and make sure it is within 10% of that required for your A/C to operate properly.
