Question about Heating & Cooling
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.
