Welcome mild weather. The heater went out and a friend found a bad capacitor. But the problem returned, and we got a local company to come out. The friend admitted he wasn't experienced with electronic troubleshooting. It turned out to be a circuit board that controls the ignitor, which I did notice was slow to get hot. It gets hot in seconds, now instead of minutes. 10/10 would recommend that company, which was recommended to me. The system is over 22 years old (we've lived here longer than that), so I'm just hoping that it keeps on keeping on.
If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
