- Bryan cover Wiring Diagram Tracing on Older RHEEM Condenser. He explains how to read schematics/diagrams on HVAC equipment and walks through an example. He takes a Rheem air conditioner and compares the physical unit to its point-by-point diagram and ladder schematic.
Point-to-point diagrams illustrate how each component is wired in a piece of equipment; these tend to keep the same orientation as the physical piece of equipment. Conversely, a ladder schematic illustrates the current flow from one side of the circuit to the other (for example, from L1 to L2). Ladder schematics generally show the high-voltage side on top and the low-voltage side on the bottom.
Although diagrams can vary by manufacturer, there are typically a few consistent components. One of these is the presence of optional components on a point-to-point diagram. These components are NOT installed from the factory and are generally indicated by some variation of (OPT) on the point-to-point diagram. Field-installed components are connected by a dashed line, and factory-standard components are connected by a solid line.
All diagrams will have notes and a legend or component code to help you interpret the schematic. The legend will help you make sense of the abbreviations you see in the schematic. (For example, it will tell you that “CCH” means “crankcase heater” or that “CHC” means “crankcase heater control.”) Notes will give you information about acceptable connections and other relevant information for wiring the equipment.
On a ladder schematic, you will be able to determine the number of poles and throws of a component by looking at the diagram. A single-pole, single-throw component can only open or close. Squiggly lines underneath a component indicate a thermal switch, and a bell underneath a component indicates a pressure switch. A ladder schematic may or may not indicate the colors of the wires. If a ladder diagram does NOT show the colors, you may need to consult the point-by-point diagram.
A point-to-point diagram typically abbreviates the wire colors, so you may need to check the legend or notes. (For example, “R” may mean “red,” and “BK” may mean “black.”) Point-to-point diagrams may also indicate the placement of additional parts that would also be installed with optional components, such as wire nuts.
In short, ladder schematics show WHAT is connected, and point-to-point diagrams show HOW components are connected. The legends and notes exist to help you understand both diagram types.

Thanks for sharing your know-how
*Used to supplement the up stairs when it gets hot outside this works very well and **Fastly.Cool** Also works good when the upstairs gets too hot in the Winter from the heater.*
These videos may seem silly to a lot of us techs, but when starting out this stuff is a God send. Good stuff Bryan.
I was eating this video up till that loud truck pulled in . Great video none the less . This was good. Clear to understand.
I like this!!! Exploring older units revitalized this channel for me
Thank you so much for these great videos! I’m learning a lot more on TH-cam vs trade school
Wow great explanation for the ac thanks sr.👍
I love these wiring diagrams explained. Thanks
Great teaching. Thanks Bryan.
Perfect, thank you.
Great job and video like always
This was super helpful, headed off to classes at the end of the month. Ik this exposure is gonna help a to.
Great explanation thanks for the vídeo sr
Thank you sir
Please do more diagram reading and components troubleshooting. Also explaining how more then one problem caused system to fail and finding them.
Hi Bryan , can you please make a video about Stay Brite 8 soft solder that is used on AC lines and their benefits or not compared to classical brazing. Can it also be used for refrigeration units
LIKE BEFORE YOU WATCH people no questions asked. 👍
hey this is my unit NOW in july 8th 2021,,i keep it running as much as i can i am old man money is tight , i still have a full jug of R22 and about 1/2 of another ,,,,,,i was wondering if it would be worthed to ? when the time comes buy a 410 unit change out the txv to a r22 and go that way ? or just sell my UN opened r22 that is sealed still and go with the 410 ? of course in central florida HEAT PUMP is needed couple more wires ,,,,,thank you for all your teachings its all good and it never hurts to review things especially when you cant work anymore god bless teachers .
Real question is, where are you guys finding the correct diagrams online? I try a few times per month when working on older stuff and I rarely find anything. I can always find carrier stuff thru the app, but I don’t have that kinda access with any other brands not affiliated with our company.
Bryan
will you be having your training seminar next march in Florida?
Russ Mitchell
It will be in February
@@HVACS please put me on your email list for reservations. thanks (rmitch2066@aol.com)

Jandy was here.
how do you explain a COMMON wire ? i was told back in school that its a wire by itself ,,,,do you have the same determination as that ? thanks
Think of common as the side that completes the circuit. Hot wire goes through a load and travels out through the common. Common is the "common" side of a circuit because all circuits/loads must complete through common.
Example: You turn on the thermostat to "cool." Red (hot) wire is jumped/connected to yellow (contactor outside) and green (indoor blower fan). When the current goes through each load it must travel back to common and through the transformer. Thus, common is the same (common) path for all loads in the circuit.
@@jericosha2842 your looking at this as a ground or return ,,,because i seen a hot wire being called a common ,,,,see the confusion that everyone has ? i get it that a circuit gets completed by A wire i am saying that its almost like asking 5 welders on how to do a job ,,,,we get 5 diff ways LOL ,,,,,
Why is it L1 and L3. Why not just L1 and L2 etc
🍺👍
Uhm, to reiterate, pull the disconnect BEFORE you jab in and pry away with a flat head.
