Same here. Your temperature difference is normal at 15d. Need to know your set-point. If the unit cycles on close to set-point, Then it's probably normal. Without more info your question doesn't make sense.

SOURCE: Cools for a while ... keeps running but stops cooling.

If the refrigerant has been accurately charged and diagnosed, I would look for an air restriction. Check your filter first of all. It sounds like it may still be trying to freeze up. Make sure all the vents are at least a little open and the return grill is not blocked. In the Rocky mountain region we like to see around 44- 50 deg. at the vents. 65 would tell us that everything is not ok.

SOURCE: Split system getting cold at first then just not cooling the room

Split Air Conditioners are not meant to run constantly. so check this first . you may have a faulty component i.e. compressor, condenser, evaporator, or evap fan. Depending on your technician you may have gotten ripped off. You need to find out if he checked the system for refrigerant (gas) leaks. A good way to tell if your ac is leaking is feel the low and high side copper pipe in between the inside and outside units.
the smaller pipe (high side) should be hot be carefull maybe touch it with an ice cube. The Large pipe should be cold but not iced over.
if there is ice on any component you should call a qualified tech. you probably have a leak. you should also clean your air filters which are right above the vents. I am a certified AC mechanic and i have seen this problem. in Iraq because of ambient temperatures being high the systems take alot of abuse and we dont fix them because repair costs exceed replacement costs alot of the time. good luck.

Hi, dealing with these ductless split systems on a daily basis, I can say you have checked some of the things I would have wanted you to check, which is good on you're part.Blowing Room Temp. air in both heating and cooling indicate that the compressor is not running even though the outdoor condenser fan is on.There are several things that could cause this. You have a compressor run capacitor that starts the compressor, but I am thinking on you're unit, it has a dual capacitor that runs the compressor and fan together. Fan is on, so I will rule this out.These units are notorious for leaking freon as the Liquid line and suction lines are not brazed, they are put together with connectors that tend to leak over time. If it is low enough on Refrigerant gas, the compressor will shut off and stay off on low pressure. This unit has a low pressure switch that has normally closed contacts, that opens and stops the compressor from any damage which in turn, you will have no cooling or heating.Do this for me, turn the unit on in cooling, lower T-stat way down so outdoor unit comes on. Go to the out door unit and where the elect. wiring and lines go into unit you will see to copper lines. The largest of the 2 lines is the low or suction line.Wrap you're hand around it and it should be nice and cold. If it is warm, just touch the smaller line, it should be rather warmer, almost hot.If both lines are of normal temp. you are either out of freon or the compressor isn't running.You can remove panel to get to it and put your hand on it to see if it is on. If the lines were of normal temp. and the compressor is not on, more than likely you have lost the charge.Look it over, the wiring to see if you see anything burned or connections burned off and so on. You can check the 3 wires going into the compressor by turning off the power at breaker and removing the cap covering wires just to make sure these wires are intact. sometimes one will get hot from power and burn off. If you see this problem, it would be something you could fix.If all looks good, go back to the copper lines and being this is a Heat-Pump, you should have 3 fittings where we install our gauges to check and fill systems with freon. Look for one that is on the unit itself and remove the plastic cap.Don't be alarmed if you do as nothing will come out.If you look inside the valve, and you see a Schrader core, you can depress it with a nail or something small, just enough to see if it has a lot of pressure in it.If very little or none, the system is out of freon. You will have to call a tech out to find leak and evacuate and re-charge system.I wanted to give you many things to check so you and I would know what the problem is, a process of elimination. If you have a lot of pressure, then more then likely you have a faulty compressor. If you feel that you would rather not check the electrical or depress the Schrader, I fully understand.You can at least check the temp. of the lines and listen to see if the compressor is running, and if it is with warm lines it is still low on freon.Please keep me informed, and again the long explanation was for you to understand more about you're system operation. Sincerely, and best of luck,

Yeah Mate,just put another can of coolant in the system.You get a hose with a kit that only fits on one of the two fittings.Any auto parts store has the stuff.To get ALL the coolant out of the can,stick the can in a bucket of hot water while it's loading the system.Old school trick.

Over heating and radiator leaks. overheats after sitting at idle for around ten minutes. its a 5 speed manual transmission 2000 chevy 2 dr cavalier.


if there is a leak then of course you will get overheating from the engine..Be very careful as this can cause permanent damage to the head gasket and it will cost a lot more to fix..First try to stop this leak before you proceed further.

Over heating triumph sprite motor cycle 955cc


Sounds like an airlock. When it fell over an air bubble would've gone to the highest point of the cooling system, & when you picked it back up the air gets trapped, if it gets trapped near the thermostat it will send the computer a false reading & fans wont turn on causing an overheat. Give the cooling system a flush. Remove lowest cooling system hose you can find I think its the water pump hose, & remove the radiator cap all the coolant will drain. Put your garden hose in the radiator turn it on & start your bike, run the hose through it for about ten minutes or untill the water coming out of the hose you removed runs clear then shut the bike off. Put the water pump hose back on, clamp it up, & fill the radiator 50/50 water/glycol. Leave the radiator cap off start the bike & get it to normal operating temperature, as it warms up air will rise to the radiator cap & the coolant level will drop just top it up accordingly. Once the bikes warmed up & bubbles stop rising,  put the cap back on & take it for a ride. Hope this helps!
