### So far i didn't get watts on my compressor explaning LRA-does not help ! becouse don't have number to multiply by 220 V in order to get replacement supplyer need watts !

LRA= Locked rotor amps.
watts is voltage times current, So use 220 time the LRA get that watts or 220 times FLA to get that watts and
multiply 220 times RLA to get watts.

### How many amps does a 5.5 cu ft danby freezer use. Start up and running amps.??

easiest way to do this is look at the label on the compressor. I usually lists RLA. FLA is usually 5 to 7 times the RLA. For example, if RLA is 3.0, the the FLA is 15-21 amps. FLA is actually LRA for about 2 seconds.

### LRA how to convert in tonage so 10 LRA How many ton and 145 LRA Copland scroll compressor tonage value pleas give me answer

LRA on the data tag stands for "locked rotor amps" and has nothing to do with tonnage. In the model # there should be a number to use. And divide that # by 12 (12,000 btu/ton). So if I had a PFG24H200 it would be the "24"and a 2 ton unit

### My islandaire ptac keeps tripping the breaker what should i look at?

If it were me I would use an amp meter and take an amp reading of the compressor when it is fully loaded. then I would refer to my name plat. which should be located on unit or if you can read label on compressor that is even better. FLA is fully loaded amps. RLA is running load amps, and LRA is locked rotor amps. if your amp readings is close to LRA or higher than FLA then I would recommend changing your compressor, The last thing you want is a compressor burn out.

### On the unit model/serial# tag there is three terms.what do they mean,compressor lra/rla and fan fla

Compressor LRA ( locked rotor amps)meaning that if you hold that rotor and do not allow it to turn, it would draw that many amps.
Compressor RLA (rated load amps) meaning the amps the compressor will draw at a certain outdoor temperature usssually 95°.
Fan FLA (Full load amps) meaning that's the maximum amps the motor will run at continuosly.

### I am looking for specs, specifically the RLA, on a Carrier Model 48LH006600(?)-- not sure about model #, nameplate data is totally faded!

It will tell you on the metal plate on top of the compressor, or sticker what the R.L.A.are and the L.R.A's are. If you cant read them, try and get what information you can from the compressor, like the name, Tecumseh, Copeland scroll, ect, The 48 would be the tonnage, 4 ton, or 60 a 5 ton unit. You should have enough of the model number for a air conditioning wholesale parts house to tell you this. we deal with this in the field daily.
Good Luck, Shastalaker7 I hope this helps you.

### Have power and light. can't hear compresser run

could be a bad start relay or start cap. could be a bad compressor. if you have an electric meter you can test the ohms of the compressor and that can tell you if the windings are good, however it cannot tell you if the piston is locked. if you have a locked rotor condition and bad starting components you will not be able to tell until you replace the bad starting components and test run. if it hums and draws lots of amps its locked rotor. most compressors will tell you RLA and LRA amperage, LRA is locked rotor amps, RLA running load amps
