Hey everyone, I accidentally shut off my furnace's power while trying to turn off a different circuit breaker. It was only off for about 5-10 seconds, but since then, I've noticed that the blower speed has significantly decreased, and the furnace doesn't seem to run long enough to reach the set temperature. Before this, the blower was actually too fast and I could hear whistling by the registers, but it always managed to hit the desired temp.
I have a Honeywell T6 Pro thermostat which indicates that my system is a single-stage unit, but I thought it was a two-stage. My furnace is a Goodman GMEC960603BNBA, and the thermostat is currently set to auto for the fan. I plan to try shutting off the breaker for the furnace for about 30 minutes, as I read that might help.
Does anyone have suggestions on how to address these issues? Thanks for any advice!

After a power outage, your system usually needs some time to reset, and a few seconds might not be enough. If you've already waited a couple of days, it could be worth trying to turn off the breaker for a longer period, like 30 minutes, just to give it a proper reset. That might fix the blower speed issue. Let me know if that helps!
It might also be worth checking if your furnace has a GFI in the shutdown switch box. If it has tripped, that could be preventing power from reaching the furnace. That's always where we start in troubleshooting situations like this. Make sure you confirm it's getting power properly.

Got it! I'll give that a shot and see if it helps. Thanks!
