New subscriber. I have been watching your videos starting with the oldest. I am amazed at how far you have come since the early videos. Honestly, your knowledge is impressive as hell. It definitely takes me back to how I felt in the beginning and how I progressed with my troubleshooting skills and confidence. I think you are way ahead of where I was when I was your age. With all of the people hating on the trades, and the lack of people getting into the trades, it's awesome to see a bright humble guy having a genuine good time fixing shit. Thanks for spreading the positive vibes. 👍
Very nice catch. Glad to be retired after 50 years of working on boilers and not having to put up with that kind of crap anymore. Those types of issues are certainly frustrating. I remember when the Honeywell RM7800 series was first introduced, and it proved to be a very reliable control. Wonder what prompted that change? But I will be the first to admit that the diagnostic readout was a huge step forward. Especially coming from the vacuum tube era.
Very strange seeing a new 7800 series control bad out of the box. I work for a boiler manufacturer and we have put 10’s of thousands of these over the years on boilers. 7800L, 7800M, 7895’s, etc. We also have a few that Honeywell made specific for us. It’s a pretty robust control. Good job figuring it out. Having the display is great for troubleshooting these.
Had to replace a control board on a brand new KCD outside unit... hadn't even been started up once and the board was bad.. swapped it out and sent it back under warranty... KCD ran like a charm after.
Gotta love when the manufactuer releases a fix for something that wasn't really a problem and the fix causes more problems.
Where ya been!??? Glad to have to new videos
Man, I wish you released more videos!

The rm7800 relay doesn’t like water. A drop of water will fry the relay. Next time try swapping the chip before the relay
