Carrier HK42FZ034 Circuit Board

Exact replacement for OEM board that had developed an intermittent fault in the main power connector region leaving me with a chattering contactor and no ac. Arrived quickly and was a very reasonable price. Also easy to install based on taking pics of original board before disconnecting and using the wire harness on the furnace access panel. Biggest thing though is that it saved me lots of money to do it myself (saved ~$550.00 vs a quote). Very happy with the product and the seller!

This product hasn't been used yet. It's a spare. I took issue with the fact that this product was not what I ordered, and not the pictured product. It's a replacement unit ( not OEM) and came with an adapter which was the cause for much confusion. The seller was unable to explain the purpose of the adapter, and, in talking to the mfr, it was determined that the adapter isn't needed for my application. The product (not counting the adapter, which added to the cost) will probably suffice.

This will keep our 15 year old furnace working a few more years. Relatively easy to change out by carefully marking each old connection before removing old board.

Arrived early, direct replacement as described and had heat in no time!

I paid a little more money to get an oem circuit board for my furnace but I received an oem replacement not a carrier board. Description says carrier/Bryant brand but it is an ecm brand board. It doesn't even look like the picture, this board is green.
