What is an RTU Unit? RTU stands for roof-top unit. All the components, including the coils, compressor, and fan, are packaged into a single unit on the roof. Traditionally, most HVAC systems have some components that exist outside, and some that exist inside.
The RTU HVAC unit provides all the heating and air conditioning needed for your space. The heated and cooled air reaches different areas in the building via ductwork and registers. You’ll also have return registers to pull air back into the system.
Other types of HVAC systems have separate components. In an air-cooled split system, for example, the condenser is typically located outside, and the evaporator and fan are inside. Also, you’ll need a separate boiler or furnace for heat with a split system unless the system is a heat pump.

On those older York boards you can bypass the compressor delay. If you hold the test and reset buttons on the board it’ll let you bypass it. Good stuff!

Sometimes I'll use electrical tape and use that to mark what it is and where it goes. Most manufacturers use a number system with or without a letter as well. Trane is a perfect example. Every wire is black and you absolutely need the wire identification to know, unless you mark it. I just replaced 2 of the 3d scrolls on an intellipak. Everything started up with no issues because i marked the wires and used the diagram to confirm. Mark your contactors too.....helps the next guy or an inexperienced guy out.

@ugeneous Ай бұрын

Don’t waste your time the leak is on the condensing unit. They use the aluminum coils at the copper connection. Every single one of these units leaks in the exact same spot. And if it’s not there, it’s under the pressure fitting on the discharge line right at the compressor. It cracks as well due to vibration.

@HonestyHVAC Жыл бұрын

What was the return temp? And what was the code you cleared when you reset it?

@JumpermanTech Жыл бұрын

Return was around 75 degrees & I didn't notice any error code. The unit never was able to receive an error as the face of the thermostat wasn't on its base to even start the machine. Also, it doesn't look like the low pressure control is working as it had a low back pressure for 410a & kept operating. Thanks for watching!

@treborwhite Жыл бұрын

If you notice in the beginning of the video you had a 6 flash code. That’s a low pressure lockout on circuit #2.

@JumpermanTech Жыл бұрын

@treborwhite Thank you for that! I didn't notice that. I believed it was circuit 2 that was running. Found it strange that circuit 2 would come on first instead of circuit 1. The pressure was definitely really low for R410a. I was surprised it was running.

@JumpermanTech Жыл бұрын

@treborwhite OK so the LED on the left that flashed 6 times is flashing a code indicating an issue. Noted👍

@HonestyHVAC Жыл бұрын

The cutout is 50psi so it likely turned off again after you left since it was running just above 50psi when you were gauged up, given what you’ve found I would be looking for an airflow problem

@treborwhite Жыл бұрын

You can spin the covers around on those contactors, so the specs are right side up 🤟

Also the 6 flash code on the simplicity board was a low pressure lockout on circuit 2.

When you walked up to the unit, the flash code said low pressure compressor too, and then you reset it and did all this extra work but still have not fixed the actual problem

@@JumpermanTech you can do the back mounting plate as well. So the coil line’s up with the control wires and mounting screws. Make it work for you. So when the person sees that you took the time to make it look right. Respect! I worked for JCI/York for years as a start up and Warrenty tech. I always did that especially if they knew your a factory dude. I retired after 35 years last March. I miss the crew and the accomplishments fixing things. Just my body couldn’t do it anymore.
