SOURCE: Will Not Heat

On the outdoor unit the fan should not be running, on the indoor unit the fan should be running. If you then check the outdoor unit with fan not running, you should be able to hear clearly that the compressor is actually working. If this is all correct, it is possible that your fourway reverse valve is seeping and needs to be replaced.

SOURCE: Indoor unit temperature between 60F & 70F after R22 charge..

If anything, it appears undercharged. Purging is not recommended. @90 degrees the high side corresponding pressure is 168.4 and Low side coresponding numbers re70psi/68degrees. With all due respect to the tech I think . If your room temp is 80, the corresponding high aide pressure is 143.6 , Low side 85 psi Yup, undercharged. Now do me a favor and don't start any "but he said" wars going. If anything, Just call him back and tell him something is still not right. Ask him to bring you a pocket rergerence for temp/pressure relationships. The numbers I gave you are for R-22 which is commonly used in residential applications. Well, good luck and keep your cool. IDon't purge. R-22 is very expensive asis everything else. You may want to dispute anny additional service call charges. Good Luck

SOURCE: LG Ductless Mini Split System LAN125hv: Heat pump doesn't run.

First check your circuit breaker or fuse that supplies power to the outside unit. It's probably separate from the inside unit. Then try to turn unit on. If the fan and compressor just make a humming sound then turn it off and check the capacitor if you have a multimeter. You can also look at it and see if the top looks expanded. That's a good sign its bad, but not all bad one's look expanded. Tomorrow I will have access to an LG service manual and can let you know what the code means. Sorry I can't get it sooner. Let me know what you find.

Tip

Refrigeration and Absolute Vacuum


I have noticed some good advice here when it comes to pulling a vacuum and recharging a refrigerator. I also have seen some not so good response to answers when it comes to someone that is new to pulling a complete vacuum. *Refrigerators and absolute Vacuum are about the most difficult combinations to obtain. First mankind has never achieved absolute vacuum and the closest we will come in our life time to complete or absolute vacuum is in outer space. When repair is done to a sealed system there are a few things to remember. 1 Once a sealed system is opened never leave it unsealed to the outside environment. Most new refrigerators have ester oil as a lubricant and ester oil will draw moisture from the air and hold it in the oil resulting in the oil carrying moisture particles up the capillary tube and creating a blockage that appears as if the suction side is pulling a deep vacuum. 2 Always replace filter drier with a new filter drier and arrow pointed into the correct direction. 3Always find and fix a leak in a sealed system before recharging. * Some leaks are in the Yoder Condenser Loop and the only way to fix is to bypass. This will sometimes show up as sweating around the door frame but much better to deal with than complete refrigerator replacement. 4Pull a vacuum as long as it takes to boil off any moister that may be trapped in the sealed system. If system has no leaks and you use a heavy duty vacuum pump this is about a hour. 5Always test gauges for leaking seals in gauges before spending so much time pulling any vacuum. *Bad gauge seals will result in moisture or poor vacuum results. 6Always charge refrigerators by weight. *Refrigerators use very little Freon. 6-8 ounces, over or under charging will result in poor cooling results all the time. 7Never try to solder steel to copper piping with just silver solder. * Always use eutectic solder for soldering copper to steel. * In this case eutectic solder is defined as Flux-Coated Silver Brazing Alloy. For example Safety-Silver 45 by Harris. 8Always use the correct oil for the correct refrigerant. * Too much, too little or wrong lubricant will damage the system. If you have questions please let me know, Thanks, Sea Breeze Here is more....... As we talked earlier I did some research on Fijitsu Split systems and as always with these units they is very little in instructions or model/size category to give good solid answers to all the possible problems you may be having. I do know with my experience that the R410A are critical during installation that they havea very good and long vacuum during pre-charging the lines during installation. One little bit of outside air in the lines will cause extreme head pressures that will also simulate some of the symptoms you described today. R410a runs at 60% higher pressure that the older R22 units did and purge and clean silver solder of fittings is critical to the unit's performance. Even a crimp in a discharge line makes for problems during installation. here is a link=> Brochure here=> http://www.fujitsugeneral.com/PDF_06/halcyon06_brochure.pdf If you need more answers feel free to contact me here or through my profile and again Thanks for using Fixya, Sea Breeze

Iinstall a new 2.5 ton condenser unit, cooling coil and a 90,000 btu furnace in my condo. I have charged the system with R410 Refrigerant. The unit is not getting as cold as I suspected. Is there...


first, obtaining the correct charge is rather tricky .. it depends on inside and outside temperatures and humidity .. you need gages to measure both high side and low side pressures accurately and match those figures up to a chart that considers inside/outside temp and humidity ... in a new install you can calculate the required charge based on numbers given by the manufacturer modified by the length of connecting pipe set ... before charging, the system had to be vacuum pumped for an hour or more (unless the system came precharged) .. all vents in the house should remain open for air conditioning and the furnace blower speed chosen for a specific temperature drop across the cooling coil .. some AC repair people dont know how to do all that properly .. it takes a true professional to optimize the system .. if you can find someone that really knows how to do this then you might try to bargain for a good price for him to just trim you system ..

How to recharge a Comfortmaker 10 A/C with R22 refrigerant


Call an HVAC service company. You can't even buy R-22 without an EPA card. And you'll need to proper set of gauges to read the high and low side pressures and, to do it right, be able to compute the dry/bulb/wet bulb temp to determine the proper charge with a charging chart.

Fujitsu 18000 goes into defrost once an hour at 28to 32 degrees outside temp. trying to maintain 70 degrees inside . test run was ok on start up. just installed 3 days ago .. vacuum out the lines. lost...


what is the lowest outside temp manufacturer suggests? Heat pumps are not very good when it gets good and cold... call the installers and see what they have to say for you.

How to insert oil in outdoor of split type airconditioner


You shouldn't have to add oil. The little bit that leaks out with refrigerant isn't significant. I would be more concerned about the leak itself. Has it been located and fixed. If not it will no doubt leak out again. Also do you know how much refrigerant to put in the system? Have you vacuumed the air/moisture from the system etc. Is the system totally flat or is there still some refrigerant in it? Let me know so I can advise you correctly.
