Question about Carrier Heating & Cooling

Open Question

50DF024 Unit had too much oil put in by someone that didn't know better. Compressor died of course. Burnout. I put in a reman comp (06E)and a suction line filter core with cleanout filter. After start up, ran smooth, some oil migrated back to crankcase. High oil level, drained a gallon, oil level barely 1/8 in sight glass. Ran unit for 2 wks, (14 hrs per weekday only)all ok. Changed a filter core again, upon start up, comp was shaking badly and drawing high current. Enough to trip breaker. Oil level in glass appeared ok. Only been looking in the glass on same side as power connections. Didn't check other glass. Removed heads, found oil in cylinders (2 tablespoons or so)and in the discharge port in the block near the discharge valve. Same both sides. It seems like I need to get trapped oil out of the system. Help! Thank you Jaime

You MUST WEIGH IN THE NEW CHARGE OF R-22. There should be a label on the side of the a/c unit that states what the factory charge was. This is only a starting point. Once you have the factory charge in the system, then turn on the unit and allow it to stabilize (5 min) . Check pressure on low side and check teperature on low side pipe. Temperature of pipe should be 8 to 15 degrees above what the boiling point of the refrigerant is for the current pressure you are reading. If the temperature is more than 15 degrees, add R-22 in 4oz increments allowing 5min in between each time you add until you are in the "zone". When you do this, your head pressure needs to be 225-250. if you need to cover the coil or block the outdoor fan to do this then do it. Hook up the vacuum pump and start over

How to fix a grounded compressor?


You cannot fix a grounded compressor. It is better to buy a new refrigerator because a grounded compressor contaminates the sealed system with acidic burned oil that will burnout a replacement compressor if installed without a complete cleanout of the acidic oil remaining in the system

My 06e run high amprage anf trips my breaker


Hi jc escamilla
Check and repair your compressor unloader valves...
If they are stuck,broken,etc...then they will cause the problem you are experiancing.
Also check you oil level, low oil could be the cause also.

Who is performing this service ? The line he is referring to is the liquid (capillary tube) suction line which is welded together for proper heat exchange. If that is the case then this should be addressed by the manufacturer. Was the system properly evacuated and a new drier installed ?
Was the condenser clean ? The newer refrigerants along with overheated systems cause any moisture in the system to release salt which mixes with compressor oil. This sludge clogs up the capillary tube stopping refrigerant flow.

I've got a compair 660A air compressor and have oil leaking out of the body of the oil pump cover.


I didn't think this was a pressure lubed machine. Is it leaking around the shaft seal, behind the flywheel? If it's just the oil leak, and the unit runs/sounds fine otherwise, you could put a gasket and seal kit in it.

You can search online for parts, but probably have better luck calling it a LeRoi 660A. Compair bought them years ago, and let the piston compressor business slowly die.

Too long of a lineset for sure. You can put a suction line trap in and add 1.5 ounces more oil to new compressor. This should keep compressor better lubricated.

the turbo is a good start remove and check for excessive play on turbine/compressor sharft, one way to check is to press down on the shaft on the compressor end (silver side) and turn wheel,if making contact with housing then you have worn bearings causing wheel to drag slow down it's speed caursing it not to work,also check the condition of both wheels, compressor and turbine if pitted or worn replace unit, if cost is a factor then a reman or a good used unit will work,

Well I dont know what refrigerant your working wqith but I know the oil press sw's Ive dealt with open after a senmce of NO pressure Difference between Crank case and Oil pump Output pressure. You'll have to pump down the compressor and install an access tee for telling you what your oil pressure is and then subtract the suction pressure for true oil pressure. Usually the oil press sw is set at factory and is tween 7 and 20 psig. If it dosnt see this pressure a heater on the OP sw will energize and if the difference isnt senced withing the heater time limit it causes the points to open shutting off the compressor. If oil press is indeed low You could have bad oil, bad screen inlet to the pump or worn out pump or low oil. BEWARE LOW REFRIGERANT CAUSES OIL TO SETTLE OUT DURING A RUN CYCLE. So if you add some oil then Refrigerant Be ready to take the oil back out important to measure how much in so you dont take out too much. Low back pressure from anything from low charge to a TXV or other valve not feeding correctly. This pressure being low can allow oil to settle anywhere eccept tyhe crank case. The Refrigerant returning toi the compressor caries it back usually unless its piped in incorectly where the oil can trap OUT of the system and not be brought back. .

Split Airconditioner


you can add oil to unit from suction valve but you have to know how much == you have to remove the cmopressor drain it of oil and add the countity that wrighten on it between 500 and 750 cc appro
as i understand your question when you know that the comp needs oil change
its when it is over heated or work at high temp
so you can hear a noise or an usual motor noise
i wish it ok

The ac makes a noise


the problem is that someone didnt put enough oil in the a/c system so pretty much you need a new compressor u can probly get a reman. for about $150

NO POWER TO MY DEHUMIDIFIER


I took my dehumidifier apart and I found why the unit no longer would start.

First, there is a fuse inside the metal compartment that houses the control circuit board.
However, the fuse was not blown. Instead I found the relay that controls the compressor,
(circuit diagram calls it RY-COMP) was not functioning and was left in the open position.
The relay must switch the compressor on/off based on humidity, full water hopper, and
maybe other factors like temperature.

The RY-COMP is a large black plastic component on the circuit board with two
wires (blue and black) connected at the top. I tested the contacts and they remained
open when starting up the dehumidifier. Doing a small bit of rewiring so that the blue and black wire
were connected and also wired to RY-COMP terminal 3, the dehumidifier came back to life.
However, this is good for proving what broke but without an electronic control to cycle the
unit on and off and to halt when the water hopper is full it's not a valuable alternative and
it risks a burnout of the compressor from constant use.

I think the RY-COMP relay is a solid state relay which could have gone bad from a spike
in voltage when plugging the unit in or cycling on/off.

I certainly don't want to buy another unit where the circuitry is not robust enough to survive
plugging in every couple weeks. I was thinking I could try replacing the relay with a magnet relay which would probably survive spikes much better.
