I have two Trane XE1200 air conditioning units circa 1998 installed originally with the 50A50-571 control boards. One of the control boards became defective during 2008 winter and furnace would not start on call for heat. The second one went bad after few years this 2019 spring when call for cooling did not fire up the circulator fan. I found this one was replacement for the discontinued board. It is smaller size than the original board and connectors have been moved around. The manufacturer has provided few jumper cables to extend original wiring in case they are out of reach due to change in position. I had to use these cables as the original would not reach the new positions. For Trane application, one has to also use the supplied jumper cable to connect the terminals for the roll out switch.Read full review

This Furnace control unit was used on many older a/c-furnaces and based on my experience, they last around 10 years, so the cost per year is pretty reasonable. This is my third one (been here since 1992) and while it 's annoying to have your furnace or a/c go out (just when you need it) knowing it's a weak spot and can be fixed easily makes me feel a little better. As for a DIY project, it's a good idea to take photos of the wire placements so if you lose track during the replacement, you can go back to the photo.

Replaced my white rodgers 50A50-241 with 50A55-843 with no problems it was exact wire plugs. Had to drill four new holes for new Module but that was it. My old module would make my blower run by itself with everything on the off position and heater will run only for a short time then cut off and blower would continue on had to turn off at the breaker. Very satisfied with product would recomend.

My control board led wasn’t blinking even though it had power. I bought this and installed it by moving one wire at a time. When I was done, I turned on the power and the furnace lit instantly. This was an exact match and the job couldn’t have been easier. Highly recommended.

Instruction is easy to follow for installation and setting up the dip switch. You need to mount the module to a difference location if you are not going to use the jumper leads that come with it. Ran fine (I'm in HVAC field for a living).
