ICM Controls ICM280 Furnace Control Replacement for OEM Models Including Goodman B18099-xx Series Control Boards, Multicolor

Replaced the board six weeks ago to restore AC performance. After sending heat through my HVAC system, the heater has ceased to be lit when the fan is turned on, even though everything seemed fine at the time. The warmed air has always been circulated this way in order to keep it warm between each heat cycle and has done so for The heater begins to heat up with the fan running, at the instant the ignitor ignites the gas and turns off the gas shuts off as well. After I switched the fan back to automatic mode, the heater was working fine again. I have a support email in to ICM, we shall see what response they give. If I see anything new, I will inform you. Announcing an update The ICM customer support team was on the line from 11 AM to 1 PM, Monday (I never received a reply to my email after one It appears that this particular model board DOES have the problem of the fan running continuously during As I explained to him, he understood exactly what I meant. Depending on a few factors, it may or may not work with the fan on and with heat turned on. This was bought in September when AC season was in full swing. To ensure the heat was working, I checked the heat while the fan was on manual control, however I did not check it while the fan was off. Be sure to test all 10 modes before the 30 days is up if you buy the ICM280! The factory computer glitch took me 3 weeks to discover after the 30 days return window had ended. As a result, I have a board with a known defect. In the meantime, I have replaced three electrolytic capacitors on the old original board and it is back in place and working. The total cost of the parts was I am 58.

This board has a safety feature that the original does not it cut off power to the system if the signal from the thermostat was too distorted. Due to having extra wires in my thermostat bundle, one of them I was able to connect to the ground in the furnace, while the other I connected to the "c" terminal in my thermostat, and that solved my issue.
If yours has the same problem, jump from R to W, and if it stops that is likely what is wrong. In order to eliminate my thermostat as the problem, I had already checked that before replacing the board, but the new board has this feature and the old one did not, so I had already eliminated that possibility. A star was taken away because this is marketed as a direct replacement, and it does not include any extra features the original does not have. Nevertheless, the board works great, is sturdy, and the tech support was good.

There is no need to worry about the square white connector on this board because the plug into it is included and easy to hook up to the thermostat connections, as another reviewer stated. All you have to do is put in a few wire nuts. The instructions explain it all. You should be aware that once you have finished and fired it up again there may be a delay of 5 to 10 seconds before anything happened, whereas on the old board, at least mine, the air blower would come on immediately when you powered it up. My original replacement turned out to be a failure, so I sat there wondering what I could have done wrong when it decided to stop working. Since then, it has been working perfectly. In my attempt to fix the problem, the furnace would sometimes fire up, and then shut down without cause. However, it still appeared flaky even when I tried new flame sensors and other tactics. Another suggestion I would make would be to move wires one at a time from the old board to the new one, rather than disconnect all the wires from the old board and connect them As far as the wiring and connections go, it does seem easier to do them one at a time. Also, make sure you take some photos of them before beginning, just in case you need to reference a photo you took.

My GMP 75 B18099-70 was very easy to install compared to the GMP 75 B18099 - 70. This mod is as simple as installing the 06 board, replacing the thermostat wires (color coded, new ones are included, super easy), and replacing 2 wires from the board to the transformer located right above the board. All in all it should take about 30 minutes to complete. In my old board, it was throwing out multiple errors depending on how it was feeling. There were days when the igniter or blower would turn on, but not the fan. The next day, the fans would begin to blow, but then shut off within seconds. I can report that everything has been fixed so far. Give it a go and you'll be surprised at how easy it is.

It occurred most of the time that when the thermostat called for heat, none of the heat was turned In any case, the exhaust fan would start and once it did, it would stay on. It was mainly the '5' error code that I was receiving. In light of what I found on Google, I decided to take a risk and replace this part myself, since I couldn't afford to hire an HVAC technician.

I was able to install the board pretty quickly as it got to me quickly. There was one problem I encountered with the instructions Three of the six wires on the circuit board weren't labeled. So, I stopped using an old wiring diagram and compared it to the new one to figure out where the wires go. It was super easy to install, aside from that. Using the new board has been a great experience. My heat works, It is imperative that both be done within one The control board is a joy to use all in all!.
