Furnace issues after power reset

Hi - I was wiring something in my house and went to turn off the circuit breaker to it, but accidentally turned off my furnace's circuit for 5-10 seconds. It's also possible the thermostat lost power during that while I searched for the right breaker (I can test that out by flipping the circuits again, if needed). I noticed that since then the furnace has reduced its blower speed considerably and when it kicks on - it doesn't stay on until hitting the set temp. Prior to this, I felt the blower speed was actually too high because I was hearing whistling around my registers, but it would always get to the set temp. I have a Honeywell T6 Pro. I was looking through the settings on the app and it says my furnace is a 1 stage though I thought it was a 2 stage. Furnace is a Goodman GMEC960603BNBA. The thermostat has the fan set to auto currently. I am going to try to turn the breaker to the furnace off for 30 minutes per another thread I found on here. Any idea what I can do to fix these problems? Thanks in advance for any help! submitted by /u/AKPatel [link] [comments]
