HK42FZ011 - Upgraded Furnace Control Circuit Board Fits Brynat

Wiring was very difficult and different than the old board. I made a Youtube video Weathermaker 8000 Fix showing the wiring. I highly suggest buying this instead of fixing a broken solder joint. There are serious fire hazard with the old boards.

Perfect replacement. Label all of your wires, if possible, before removing the old control board--it will save you tons of time.

Product arrived as promised - 2day priority. At first we thought is wasn't the correct part and sent a request for return. Seller immediately obliged with a RMA. Fortunately with a call into a service technician, he identified the part as correct with some wiring changes but would not install it due to company policy. Quoted $895 for part and install. So, I took the time to study the old part and new part schematic and after a couple hours figured out how to install it. Turned on the power and blower started. It's been a few weeks and all is good.

Was in a bind -14 degree could not locate parts for my furnace the died in sub zero temps. Arrive quickly. I have minimal Electrical experience. Took me a little longer than I expected but everything worked.

The box showed up smashed, I'm currently waiting for the furnace tech to install it. I hope it works and doesn't have any damage. It really should have been in another box for shipping. The factory sealed box is not intended for shipping.

Nice

Works great. Need to be very specific reading and following instructions.

It fit perfectly and works, so far I have had no problem. Only time will tell, but I suspect that this unit will last for many years.
