White-Rodgers 50A65-5165 White Rodgers Direct Replacement for Trane Single Stage Integrated Furnace Control, 80V Ignitor

My furnace was trying to start (Trace XE 90) but whenever the signal was sent to the gas valve it would lose it almost immediately (verified with a fluke). It would start sometime and run fine for a minute or 2, but then the gas would cut off and it would try and ignite it again. Verified the igniter, pressure switch and flame sensor were all working fine. Ordered this board Friday afternoon, received it Sunday evening and within 20 minutes of it landing on my porch had it replaced and the furnace was running with no problems. As said in other reviews - take plenty of pics before pulling out the old one so you hook it back up correctly.

This was a great economical replacement for my Lennox 50A65-120 control board. Only wish it came with a spade connector for the flame sensor. You’ll have to solder one on if you want to make it work. Everything else was plug and play

We had both furnaces get flaky when the renter didnt pay his bills & the gas & power were cut off, last winter. We had the older, bigger version from about 1987. We bought the smaller, less expensive, newer, open-box version & it fired right up, without incident! Our suggestion would be to get a set of good-quality vinyl wire labels to label all your wires before ever taking any wires loose! 100٪ mistake-free! Also, carefully consider the placement, because this unit is more compact than the 1987 version. On one Trane, we turned the unit upside-down to minimize wiring lengths. We used existing wire. On the second Trane, it has a tiny peephole to view the LED. In the original, the user had the squat down & look up to see the 1987 LED. We carefully adjusted the mounting so that the user can see the LED while looking down. In fact, the user can stand fully erect, across the hall, to view the LED. We highly recommend these as replacements! Note that after 10 to 15 years, the ignitor get oxidized & are slow to warm up. The first sign is that the unit is typically lighting on the second try. Consider replacing the ignitor to save time & trouble. In our case, these two $80 units saved us from having to replace perfectly-good $5500 Tranes! Plus you get to have the satisfaction of accomplishment in a job well-done! The supplied user manual that comes in the box is excellent & details the exact cycle lengths, so you know what to expect as the Trane lights up! Get one today! Keep those old Tranes rolling!

My inside AC fan would either run all the time, even when thermostat was removed, or would just run a few minutes then stop. Seems like it reset after turning off the breaker. The outside unit was still controlled by the thermostat, i.e. would run when it got warm in the house, even if inside fan wasn't running, The LED on circuit board (integrated furnace control (IFC)) in the inside American Standard furnace/blower unit was on on continuously. Diagnostic code listing on IFC sheet said that meant IFC board (this purchase) needed to be replaced. Some YouTube videos said to replace the relay on the inside blower, but on my American Standard AC/Furnace, it was integral to and soldered to the circuit board. The new integrated furnace control (IFC) was pretty easy to install, ended up using existing plastic fasteners and removing fasteners from new circuit board as this was easier than trying to removed them from the furnace. All electrical connections on new board were in the same place as on the old board, so I just removed wires/plugs one at time and connected them to the new board. It worked great, inside blower now responds to thermostat. Had an AC tech out to check freon levels a week later and he said he'd have charged me $485 to replace the IFC and that 98% of homeowners wouldn't try to replace it themselves.

Replaced my old one in a Trane 80XE, easy and worked out of the box. Cheaper than the $1700 quote from the local HVAC repair team...

Great product l. Great price.

This board is different part number but was exact replacement for my Trane XR80 board # 50A65-475.

My American Standard furnace was not lighting up. I determined it was the fact that the controller (CNT03076) was not providing the ~24V AC to the gas control valve during startup process. I powered the gas control valve directly from the furnace power supply (24VAC) and confirmed it was opening a closing so I know it was not the control valve or mechanical. Relay on the main board must have gone out that provides the 24VAC. Replaced the board with this one and all is good. Its been in operation for a month now. Allowed me to test and clean all the other components of the furnace like the limit switches and pressure switches etc. This was a great learning experience. Just take photos of all the wire locations when replacing. There are quite a few to keep track of. I listed it on eBay brand new six months old. $16 how things are with you
