Although it’s universal and works with several voltages, it was easy to install and worked great. I would purchase it again.

It's very easy to install if you know what your doing. The component is working great as of now.

I was repairing my a/c unit and this was much faster and less expensive for me than making the 90 mile round trip to the HVAC supply house. It was the exact replacement which I needed to get back in operation.

My furnace stopped working and as you know hiring a company I could have easily paid 300.00 to fix it , if not more bec if you do not know anything, they can sell you a new equipment. It cost me 15.00 dlls to fix the problem. But you have to know what you are doing or else you will fry the board. Part material is cheaper then the original but it does the job. Happy is working again!! Thanks Amazons for selling almost everything! I hope it last.

I had to replace a transformer in my furnace... this did the job perfectly. I'm 4 months in, and it's still going strong.
