3. Reading Ruud Model Numbers List

1. The first 2 numbers represent the factory where they were manufactured, the second 2 numbers are the year and the letter is the month where A is January, B is February, etc. An example would be 5800A12345. 58 is the factory, 00 represents the year 2000 and A means it was manufactured in January.
2. I have a split system Ruud condenser m # XXXXX s#7936 and Ruud Air Handler M# XXXXX S# XXXXX It has a Ruud heater 7kw model number RXBH-1724C07J. It's factory terminals were on 1 and 5.
3. How to read ruud furnace serial numbers Your Mac's serial number is the unique identity that distinguishes your Mac from all others. You must provide your Mac's serial number when you request warranty service. You might also want to look up your Mac's serial number if you report it as stolen. The easiest way to find your serial number depends.
4. For Ruud, you should look for the second cluster of digits of the model number. It will be a number divisible by 6 or 12, and represents the nominal BTU of the system in thousands. A ton of air conditioning equals 12,000 BTU, and 24 divided by 12 equals 2, so the data plate below indicates the system is 2 tons.

How may tons is my Ruud air conditioner or heat pump?

Water Heater Serial Number Decoder Manufacturer Brand Serial # Ex. Key American (Prior to 2001, American was owned by GSW Corporation and manufactured water heaters for nearly 50 different brands. American was acquired by A.O. Smith in 2001 and currently only manufactures American, American-Pro-line, Premium Plus, U.S. Craftmaster and Whirlpool brand water heaters.).

You can determine the “nominal” condenser tonnage of your HVAC system by examining the model number on the data plate at the side of the condenser (outdoor unit). Just like the nominal size of lumber or an air conditioning filter, the exact cooling capacity may be a little more or less than the nominal rating, but it’s close.

For Ruud, you should look for the second cluster of digits of the model number. It will be a number divisible by 6 or 12, and represents the nominal BTU of the system in thousands. A ton of air conditioning equals 12,000 BTU, and 24 divided by 12 equals 2, so the data plate below indicates the system is 2 tons.

Here’s a rundown of the range you will encounter: 18 = 1.5 tons, 24 = 2 tons, 30 - 2.5 tons, 36 = 3 tons, 42 = 3.5 tons, 48 = 4 tons, and 60 = 5 tons.

If you are unsure whether you have found the right two numbers, you can double-check it by looking for the “RLA” rating on the data plate. RLA is an acronym for Rated Load Amperage, and is what the maximum amperage should be when the condenser up and running. If you divide the RLA by 6 for older units and 5 or 6 for newer units, you should get a number that approximates (not exactly) the tonnage of the system. Make sure you use RLA and not LRA, Locked Rotor Amperage, which is the surge of amps necessary to overcome inertia and start the system. It averages around five times the RLA.
