About a week ago my heater stopped working and red service light was on. No codes were showing on the display.
I removed the panels looked at the the led on the back side of the control unit and the SFS led was lit. I replaced the SFS sensor and everything worked great until today when the same problem happened. I supposed it is possible for the SFS to go bad in a week, but I suspect something else is causing the problem. If the sensors are failing, why wouldn't I get an E05 Code?
