OEM Carrier Bryant Payne HK42FZ011. Furnace Control Circuit Board in Case. OEM in Carrier, Bryant, and Payne. Part / Model Numbers. Checked in and removed from a working furnace. By an HVAC professional. We observed it starting, running, and shutting down properly twice before removing it. There were no issues in the history. A control board has many functions. The most reliable way to confirm it works properly is to actually see it in operation working properly. After checking in the furnace, the circuitboard was removed from the case and inspected closely, to make sure there are no loose or broken parts or bad solder connections. You can see the Control Board Components on top and the Solder Connections on the bottom in the photos. This is the part you will receive. There is an excellent value. Please understand I work for an HVAC company. They are kind to allow us to sell parts equipment we removed. I do not sell within their service area, and do not take time off from work to meet someone to sell a part. Thank you for your interest in my listing. This is not dealer or a business. I never sell parts that have been installed, used or even handled since they were checked. You will never receive something from me that’s been used after checking it.. If the most important thing to you is knowing you are purchasing a part that’s been checked and kept secure since checking – I’m a good choice! I do my best to make this possible, including. All parts I sell have been checked as appropriate to be sure they work properly. Part and model numbers are included in the Title, the “Item Specifics” section of the listing and in the Description above. Clear photos of the part from multiple angles are included.. Some of these include the part numbers. After checking and taking photographs for listing, all parts are stored securely, safe from moisture and temperature changes. Control boards and electronic components are stored in static guard. I do not sell parts that have been out of my control at any time since checking. All parts are packed securely. Control boards and electronic components are wrapped in static guard. These are your responsibility. Buyers are responsible for purchasing correct part for their application. Relevant part numbers are included in multiple places of this listing.

Buyers are responsible for correctly diagnosing the need for this part. Most manufacturers and suppliers of HVAC equipment and parts recommend installation and servicing only by licensed HVAC professionals. A significant amount of education, training, and hands-on experience is required to become a licensed, HVAC Professional. In my area, it’s a five-year program, combining classroom and hands-on training, including 1,600 hours as an apprentice working with a licensed professional. While it is possible for someone to fix their own equipment by watching YouTube videos and viewing online suggestions – it is significantly more likely someone trying to fix their own equipment will have issues than a licensed, HVAC professional. You have seven days from the date you receive it to check it and report any issues. To all others, please understand you are purchasing this at your risk and not mine. You installed it incorrectly, or. You have another issue in your equipment that was missed or not diagnosed properly. If you bought the wrong part, or if it fails to fix the issue in your equipment – please write, and I will try to help you figure it out. I’ve done this for many people you can see their comments in my feedback. Please write if you have any questions. Thank you for your interest.
