Review on Controller Combustion Detector with TOPCHANCES Compatibility by Charles Butler

I wasn't sure if this part would work for me. But the part was identical in number and appearance. I tried it for the F5 series. Received it quickly and it was identical, I was able to install it in minutes and within minutes the burner was up and running. I've had no problems at all and if it takes me even half the time I'll love it. The original only lasted about 10 years, so there is definitely nothing to complain about. Will do business with seller again in the future. ***Update: It's now late November 2021 so it's been 3 years and it's still working, no issues. I felt like I had to post this update.
