Good diagnostics, usually the 8 code comes from corrosion in the gas valve and isn’t as repeatable. Cycle power and it goes away, for a while. Then you get a call back and the board gets replaced and it goes away, for a while.

I may be wrong, but I think Carrier always uses brown as common.

@johnostro7153 8 ай бұрын

You are correct, the brown/uninsulated spade is always common. This was either not the correct board or an updated board with slightly different pin locations.

I had this same problem with a Cleveland tilt skillet. Would work fine on Low fire. Put it on high fire and the Honeywell would flash 6 times for internal control fault. COM and 24 were reversed. Luckily I found it b4 replacing control even though that was my first diagnosis but something told me to dig deeper.

Comstar was a Refrigerant manufacturer that made R-22 replacement refrigerant. If I remember right it did not sell very well and I think it had a really high glide. The last time I heard anything about the company was like 15 years ago.

The uninsulated spade should have been the common to the gas valve on virtually every carrier for the last 40 yrs, the new board may have had slightly different pin locations than the original but hard to blame the guy who installed it for putting the wires back exactly where they came from. I've looked and hundreds of those wiring diagrams and It does 1000% show you on the wiring diagram which wires go where by color or number and it would show that the gas valve was wired correctly according to the diagram. My guess would be that the boards installed were not the original part #, Carrier went through several iterations of that same board that all look and function almost identically and occasionally they even intentionally change pin locations on electronics for their down brand equipment to prevent people from buying cheaper replacement parts. Any time you're given a replacement/updated board to install you need to check EVERYTHING after installation. These boards will also give that code if the transformer tap was never switched on install and may not happen until the transformer "breaks in". You will also occasionally get that code from those boards just from having a bad/corroded connection at the gas valve because the input terminals at the gas valve tend to get snow on them in high winds. Also bad grounds and open or low impedance coils for the gas valve will give this code. And one time, literally ONE time I had the ignition wire bundle that runs down into the burner compartment get so overheated from a bad HX that the insulation had partially melted passing a stray voltage from a pair of the wires that were touching even though the insulation between them was not 100% melted through so manually separate all the wires as a precaution, if any of them stick together they were overheated and could cause a problem .

@mallow399 Жыл бұрын

Looks like there was some good hackery on that unit. Great find. In my experience if ya reset a code 8 and it runs fine and all wiring is good the board is pooched. Most code 8s re appear later down the road.

@HughesManHVAC Жыл бұрын

If the hi fire wire was disconnected it worked like a single stage valve or if it was only calling for first stage. If both stages were calling it would give the 8 flash code until I reversed common and 1st stage heat at the valve. I was definitely getting the 24v at the common terminal on the gas valve and not at the low fire terminal. After I swapped them everything worked fine and the valve acted properly and adjusted gas pressure when hi fire was called.

@EverythingHVACR Жыл бұрын

@HughesMan HVAC just trying to think electrically what exactly was happening, the board obviously caught the problem. My first thought was your feeding 24 volts to common, the fuse should blow, but you're not shorting it out. You are feeding the common of the valve with 24 volts. Good stuff Bro, someone smart on here will probably give a great answer, I'm not that guy 😆 .

@mrbugenhagen3364 Жыл бұрын

@@HughesManHVAC Never worked with gas but to me it looks like a two stage gasvalve is just two solenoids basically. So if the common on the gas valve is not connected to earth and is just one of each end of the solenoid coils tied together. Then you could swap them and one coil would work by itself. But if you have the other one connected aswell 24v would be on both sides of the second stage coil and it would not energize and 24v could possibly backfeed to something. I am sorry but I do not have enough knowledge about these boards to tell.

I always admired you commercial guys, Had the opportunity to move that way a while back with my current company. I had done some commercial with my prior company and was ok at it, but chose to stay in my lane with residential. I supervise a 12 man residential team so I like to think I made the right choice. But still like watching you guys. Residential 2 stage is similar, need to energize in the proper sequence. Just curious, with that big open hole in that condenser panel, would that not cause high head pressure in AC with that bypass air, especially combined with a dirty coil? I need to watch more of your stuff.

@HughesManHVAC Жыл бұрын

Thanks for watching! I did cover that open hole with some sheet metal but I didn’t film it. I did resi for about 14 years. I like both sides but the commercial stuff is more enjoyable for me. Thanks again!

@EverythingHVACR Жыл бұрын

There are actually some units like this that the disconnect is in the place of the hole on the condenser panel. They make all the panels the same even if your disconnect is in a different place, it's common to see these knock-out panels missing, I always cover them as Ryan said, it will bypass some condenser air flow
