OK do you have a pin connection style thermostat, meaning when you take the head off it has pins that contact to the base?
OK often the small pins get a little dirty or the tabs where they connect and slide in the base do not make good contact. I recommend taking off the head cleaning the pins with some fine sandpaper and carefully bend the lot tabs where the pins slide in together tighter so they make better contact with the pins and try it.
Yes sometimes you are moving the thermostat and those pins making the connection when turning it on and off. This happens a lot with that style thermostat.
No I thought you meant the switch on the thermostat, if you cycled the main power switch you may have had an error on the furnace board flashing and then you would have reset it. If it happens again take the panels off the furnace and check for any flashing error on the furnace control board, they are listed on the panel to identify an error if flashing.
Yes a dirty flame sensor would be a good thing to clean off with some sand paper as well and then see what happens the key is to not shut the power off when it happens as you want to see the error.
You just need to remove the panel to get at the board should be just two screws and it should lift off.
Give it a few days and see what happens it will not hurt anything, if you can get at and clean off the flame sensor I would do that anyways as that is a common failure on the Goodman units as well.
Seriously? It is 1:33am do you work for free at 1:33am at your job? Probably not, you probably get double time. Take care customers like you make me appreciate the good ones.
Take care I wish you the best
