Our previous service technicians had been out and looked at the furnace, but were unable to figure out the problem. They recommended buying a new furnace, so we decided to deal with it as it acted up, but it kept getting worse and worse until it became useless completely. The Johnson Controls G776RGD-, which had been leaking, was a really expensive and difficult part to replace, so I replaced it instead. I found an excellent link (search "cozy parts Johnson ignition control replacement") that had some extremely useful explanations about replacing the engine control with this new ICM one. Fortunately, making that change has solved the problem, and my 20+ year old furnace is once again working perfectly. Ignition Controls are subjected to a lot of electrical stress, and the Johnson Controls modules that were originally used in Lennox furnaces were found to be prone to failures, which exhibited intermittently in a variety of ways. A conversion kit, the 53L90, has been released by Lennox that lets users convert from a Johnson Controls box to a Honeywell box, complete with brand-new flame sensors There are only slight modifications needed to either the Honeywell Ignition Control or this ICM Ignition Control in order for it to work, and this is a much more reasonably priced alternative to that conversion kit. So far, this ICM control has been working nicely for me and I am quite happy with my purchase. It has restored an old furnace for $100, saving hundreds of dollars in repairs or thousands of dollars in a new furnace installation. During installation, keeping in mind that you will need to relocate a couple of wires in order to use this ignition control, keep that in mind. Due to this, you will need to replace two wire heads. If you have a wire stripper and $5 or less, then this will be fairly easy to do The old spade connector needs to be cut off (try to save as much wire as you can to make the connections easier), the wire should be stripped about 1/4 inch, a 1/4 spade connector added, and then it should be crimped. you'd like, you can wrap all the wires with some heat shrink (or buy insulated spade connectors) to make everything neat and tidy after you rewire it. In addition, you will need to replace the ground wire as well, since the Johnson Controls module only had a tiny ground wire connected to a plate on the back. As a result- It would just be a matter of removing the wire from one and plugging it into the same labelled socket on the other as with the old Johnson Controls module. Purchasing the connectors from the hardware store was the time-consuming part of the project.
This unit was used to replace a failed part in my older Lennox HVAC system (model A couple of new female spade connectors were spliced into the existing lines, and the install was straightforward. A 1/4" spade connection is used on all parts of the new ICM unit. In three of the wires, I had smaller female ends, so I had to replace them. It should be noted that this machine does not have the metal back plate of After that was completed, mounting the units was straightforward since the devices were the same size and had the same mounting points. It would have been better if I could have given this seller a higher rating, but I had to return the first unit I received and order a second one. One of the first ones I received was missing a spark plug connector, and had a broken insulator at the spark plug. It is obvious that this unit was used and has poor Above is an image of the unit I received for the first time. Located in good condition, the second unit was like new. It was an easy fix and saved me some spending money. Overall, I was satisfied with my ICM unit. Please read on to learn more about the symptoms of my HVAC When I turned on the HVAC, I discovered that it would only ignite after I cut the power to the system and then reconnected the power. At first, I thought it was the flame sensor, but after doing some troubleshooting, it was the fan motor. This is essentially a reset. In the event of restoring power and activating the demand for heat, I saw the led light up solid and heard the igniter click after doing so. Clicking could be heard on a continuous basis, along with the pilot light igniting, followed by the burners (flame sensor functioned well). In fact, once I turned off the system and restarted the demand cycle, I noticed the clicking was only "intermittent". There would be an attempt to light the pilot but this would not be successful, and the pilot would not light another time. The HVAC would need to be reset to begin the process again. It was decided to replace the ignition control module since the igniter was acting in some manner.
In order to replace my G776RGD, I bought this device The unit that was in there was number 11. It turned out to be a direct replacement for my unit with a different model number, even though I did not know whether the unit would work. I only had to replace some of the crimp wire terminals with larger ones in order for it to fit. Previously, my old box had a ground cable running from a ground terminal to some feet at the bottom of the box, this was not present. A simple fix is all that is needed. My furnace case has a screw that you can ground to the same wire.
The electric supply to my furnace had been shut off by a breaker (or switch on the furnace) so I turned off the gas (for safety). It was necessary to reduce the size of the terminal connectors for a couple of them and increase the size for a couple so they would fit. It is possible to cut the strip and crimp on another terminal too. My only observation with this unit is that it produces sparks for a longer period of time than before. I installed this unit, however, and since then the led has been on, and the furnace has not shut off prematurely.
Let me tell you what I can. There is no problem with it. Despite the price being right, I would recommend it. The installation is easy even for a layman. The furnace should be turned off by cutting off the electricity. You should take a photo of your original installation and double check the The process is easy. We will have to wait to see how long it will last. When I look back in 10 years, I will tell you.
Replaced my ignition control board and found it to be fairly straightforward and It did require me to replace a couple of ends of the wires coming from the furnace since the old ones weren't the same size as the new ones.
I am still very satisfied with the product a year after I purchased it We'll see how things pan out in time.
