I would like to start off by saying I'm not a complete dumbass, but I might have done a dumbass thing to my furnace. Well, we just kicked on the heat for the first time this year and the furnace was blowing out cool air, probably more like room temperature air. I went down and looked at it this morning half asleep and cold without my contact lenses in yet and moved my high limit switch to where it threw a spark then my furnace quit blowing air. I went back to look at it a couple hours later, this time with my brain functioning. I checked the "blinking red light" so I could look up the code and the blinking red light is not blinking or coming on at all. I looked it up and the code is CHECK POWER. I flipped the circuit breaker off/on, it was fine, and went back to the furnace where I flipped the power switch off/on a few times. I noticed a very low humming noise like something is getting power. Just to be thorough, I turned off the thermostat and checked again. This time, as expected, there was no humming noise and still no blinking red light. Right now, I have the thermostat off and will leave off for a few hours before checking again (is there a certain amount of time I should wait? I read to leave off a few hours so I'm trying it). If this doesn't do anything, any ideas? Thanks in advance! I will do some more searching in the meantime to see if I can find any ideas myself.
