| Sep 15, 2022 at 23:32 | comment | added | HelpEric | @Ruskes sorry one more time. When you say pull up, you mean away from the board? or up vertical (to the side relative to the board) I still can't get these things to budge at all on the heat/cool or even the spare, using needle nose pliers, etc. they wiggle, but never come loose. | |

| Sep 8, 2022 at 20:03 | comment | added | DIY75 | @HelpEric They are pull up straight. BUT sometimes like in your case there is a small plastic flap (on the left) that holds them in place. Very gently push the plastic flap away and pull the plug up, you might have to wiggle it bit to come out. | |
| Sep 8, 2022 at 19:59 | comment | added | DIY75 | @HelpEric can I see a pic of where do you plan to stick the black in and where is the Yellow ? Also NOTE, changing the Fan speed will impact the cooling performance. PLEASE read the manual that I posted for you. | |
| Sep 8, 2022 at 19:12 | comment | added | HelpEric | @Ruskes - one more simple question - should the wires just come out or do these lock in? I tried pulling on them and using needle nose to pull straight back and none of the current or the "spares" really budged much either. Maybe they are just stuck in, but I don't want to break the board in the process of trying to move things around. Ideas? | |
| Sep 8, 2022 at 14:26 | comment | added | FreeMan | @HelpEric I doubt that setting the motor to blow at the lowest speed would cause any problems, or they wouldn't give you that lowest speed. Also, it's important to know what model you've got and where you fall in the "Notes" column, but you can also determine that by simple experimentation. It's odd that the Yellow & Blue are opposite on some models, but it won't hurt anything to run it at the "wrong" speed for the model you have. Instead, it'll just be a different speed that what you may have expected. | |

thank you. Before changing anything, I want to attach photo to my original question and confirm - To me it looks like currently cool==black wire == hi speed. So if I were to switch the heat and cool at the bottom left corner then I should expect it to be less loud and I could switch these when the season change again if I feel the heat is too loud? This should be less risky then going yellow which is med low as that might not be fast enough and could cause a problem with overheating from insufficient speed?

| Sep 8, 2022 at 4:12 | comment | added | DIY75 | @HelpEric I wish they would instal a switch at least, but the philosophy is you do not use it often, if at all. At least they put multiple speed motors. Yes, you would be 92%. You can not miss the fan motor, then just follow the wires | |
| Sep 8, 2022 at 3:44 | comment | added | HelpEric | As a follow up, I could also foreseeably get a variable speed motor that is compatible with the system? I am surprised there isn't some type of device that could work like a switch/toggle or emulate the difference based on measuring some other input. | |
| Sep 8, 2022 at 3:41 | comment | added | HelpEric | thank you, i will start by taking a photo with the power off. I assume I will be looking for it to be labeled "cool" and "heat". In the table you posted, I am the second line, "92%", correct? Will also go and read the manual. | |
