Ruud heat pump capacitor size

Hi, I am currently working on a five ton Ruud heat pump. The run capacitor for the compressor is bad and all the information is rubbed off of the capacitor. Can you tell me how to get the correct size capacitor. everyone i talk to at the parts stores just tell me to use a hard start or the turbo 2000 but can not tell me the correct size. The condensor model number is upca-048jas and the compressor model number is elcrml 0400

A hard start or turbo 2000 will not work if the run capacitor is bad. You will need to contact a ruud supply house or dealer with model and serial to find out the exact match. I have checked my sources and came up empty handed. You could try getting a 35/5 MFD at 440V or a 45/5 MFD at 440V as these are the most common capacitors used in Rheem and Ruud equipment. The key is that you will need to check your amp draws on both motors against the nameplate rating to make sure that you are not over-amping the motor. Also check the nameplates on both of the motors. Most condenser fan motors and some compressors list the capacitor size they require in a somewhat less than conspicious location on the label.

Ruud 5 Ton UAKA Condensor fan running but compressor won't start. Internal thermal overload cycle.


Have you checked the wiring going to the compressor to make
sure it is not melted? Next, are you
able to put your hand on the top of the compressor? Check to see if it is hot or cold. You might have a bad run capacitor so let the
unit turn on, wait about 5 minutes, turn the unit off, and then tell me if the compressor
is hot or cold to the touch. Next, are
you comfortable with a meter?

My 4 year old Ruud home a/c compressor stopped working. inside fan blows but compressor won't turn on...what can I do prior to calling the gas company who installed the unit...


Ruud parts warranty from factory is 5 years, the capacitor has possible gone out, it will be in the contol compartment on the out side unit and is a dual run capacitor that controls the compressor and fan motor. Recommend if capacitor is bad to replace entire capacitor. As Stated above the parts are under warranty if under five years old. To verify age the date code is in the serial number after the "F" **** week/year of manufacture. Also outside unit has independent power supply so check fuses if any and circuit breaker.

I have a 25 year old Ruud A/C. The outdoor fan isn't turning and I can hear the condensor humming. There are 2 capacitors in the the electronics box that the schematic says are running capacitors. ...


The 3 microferad capacitor goes to the fan motor. The bigger one goes to the compressor. If the capacitor is swollen or pregnant looking it is shorted and needs to be changed. If it has discharged oil it has shorted out. If you can't read the mfd (microferad) you can go by the rated tonnage of the air cond for rule of thumb.

2 ton condenser = 25mfd capacitor
3 ton condenser= 35 mfd capacitor
4 ton condenser= 45 mfd
5 ton = 55 mfd

again, this is rule of thumb but should get your unit running again.

I have a Ruud Model # UACC-036JAS. Any idea on


Hi, yes the number you are showing me 036 indicates its a 3 ton unit. For every ton of cooling, you will have 12,000 btu's of cooling. 36 divided by 12=3 ton unit. Its showing me also its a Ruud Handler 2.0 ton which would be a Model# UACC-024JAS? If your mobel number is the one you gave me, UACC-036JAS, this is a 3 ton unit, absolutely no questions. I hope I have been of help to you. I am a licensed air conditioning / Refrigeration /Heating Contractor. Let me know if I have been of help.
Sincerely,
Shastalaker7
PS If this is a split system with the indoor air handler and condenser outdoors, both coils must be the same tonnage for it to work for you properly. You can't have a 2 ton indoor evaporator coil with a 3 ton condensing unit.

Compressor size


Square footage is how you determine what size of an AC you need, say two bedroom house with 1500 square feet would require a 3 ton unit but I would go to a 4 or 5 ton depending on brand and what you may do in the future, Like adding a bedroom or bathroom and how many people will be living in the house, a heat pump normally last longer the bigger it is and is more efficient than a smaller size. Just think like this, a 3 ton will run 30 minutes to an hour longer to cool the same space as a 5 ton so if the five ton does it 30 minutes faster it will not run as long. And when it has to pull down the temperature again it will do it much faster. So less run time means faster heat or cooling and less energy is used. I have found that the bigger units are made better and last longer as a general rule. And to understand the 3-ton and 5 ton let me say that it means how long it takes 3 tons of ice to bring the temperature down 10 degrees, the old BTU’s British thermal units. However the bigger the unit the more well built it is normally and the less maintenance required. 5 tons of ice would get it cooler faster. But one thing to keep in mind a heat pump is only good for 20 degrees temperature range, for instance if the high range is 80 then the low side would be 60 in order for it to be efficient so if you have it set in the house at 72 degrees on the high side and low side would be 52 degrees. But the larger the unit the less time it would take it to recover from the heat differential.

We have a fairlynew 5 ton Central Ruud or Rudd unit that it is so noisy in the yard that we can not stay out there. We thinkit is the compressor. Help


I have a new 13 seer rheem or ruud same thing. I can not here it run. Uou must have a bad compressor. Ruud put schroll compressor in and when they start to go out they will drive you nuts they are so loud. Get it changed before your warranty runs out. Ruud will change your compressor if it to noisy. No problem. Russ
