Still running good since last post. Has been two days straight now with no issues. Hoping it stays. Fingers are crossed. No idea how the replacement pressure switch would have gone bad in two months. Will update in a few more days and then call it good at that point. Thanks again for everyone's help!
Furnace still running good. History still clear. Must have been another bad pressure switch. Thank you beenthere, aa7483, and yuri for all of your help. I now have a great tool to use later on when testing furnaces and feel even more comfortable troubleshooting furnaces. Hopefully I am not back on here anytime soon. Hope others can learn from this post. Thanks again!
Glad to hear it is working. Pressure switches are all cheaply made offshore these days and you get duds. Years ago they lasted for 20 yrs or longer but they don't make that quality anymore in appliances or anything.
