"Just What Was Needed"

The weather went from hot, about 80 degrees in October to very cold, about 30 degrees in one day and my furnace chose to stop heating. Called HYVAC repairman and was told the control board was bad and would be $700 to replace. To make a long story short, I purchased the exact board for about a $100 bucks from PEX Supply that arrived very quickly and replaced the board with the instructions provided. Today it is 27 degrees in Alabama and my furnace is working great! Of course, it will be back up to 70 degrees in 2 days... Crazy for sure! Would definitely purchase from this company again.

Armstrong Ultra SX 80 furnace circuit board

My Armstrong Ultra SX 80 furnace circuit board cooling fan control failed during a heatwave. I wired the fan motor direct. Ordered the new board. Supply House promptly shipped it. Unfortunately UPS lost it for a week. I installed it with no issues. about 2yrs ago I bought a draft motor assy. from Supply House. No issues. Thank You Supply House.

Q: Difference between Armstrong r40403-003 circuit board and Lennox 19s83? I have Lennox g20q3e-75 furnace. Can I use the Armstrong part?

Hi Cris, thanks for writing in. The parts list for your unit specifically calls for Lennox part number 19S83, so that is the board you should go with to replace the existing board.

Taletha, The Parts List we have does not show the Board. You should contact Armstrong directly for confirmation.

Tony; Although I am not specifically familiar with your furnace model I would expect that this circuit board will work on your furnace as is it a quite universally used board in many furnace units of Armstrong or Lennox make.  If you are able, you might look in the circulation fan compartment of the furnace and find the circuit board mounted there.  You can easily read the part number on the board to  verify the model.I researched the web quite thoroughly when I repaired my furnace and found Pex to have the best price and service available.  I highly recommend them. Best wishes,Jon

Skip; Regarding your inquiry as to the application of the described blower control circuit board I can tell you that I don't know for certain it applies to that model of furnace but I would bet that it is the appropriate circuit board. That particular circuit board is very common and used in many applications so I'd bet that it would work in yours. Also, be aware that Armstrong and Lennox are the same manufacturer so you might cross reference it that way too. I'd say that you would be safe to use it. Jon

Yes; this board, R40403-003, would be the replacement for your unit (model EG6H80DC14-1) for the cooling side. If you needed to replace the heating side of your unit (on model EG6H80DC14-1), you would need part number R38691B-001, which is an ignition control.
