I am running into issue with having solar. The control board in my AC/Furnace is bad. I think is was bad when the home was delivered. The tech told me today that my solar voided my warranty "because of unstable voltages and the control board is sensitive" what a load of crap. I unloaded on my salesman and they are covering the cost. I'll do the swap.
I once bought a replacement 1012-930 control board for my furnace on eBay. Prices range from $25 to $150
That was maybe a decade ago. I've had a couple faults past couple years. Fan had been kicking on needlessly (thinks there is an over-temperature sensor or open wire), just recently was igniting gas and shutting off after seconds. Tried replacing flame sensor but that didn't fix it.
Both of those I fixed by removing board (photograph, also mark wires or bundle with tape so you get a couple dozen flying spade terminal wires back in the right place.) Put in a sandwich bag with IPA (rubbing alcohol, not the stuff you drink.) Shake and invert to clean. Remove and dry with hot air gun to ensure no shorting by water. Reinstalled, and it works. (I've been running electric duct heater, want gas option available for high time of use rates or battery operation.)
