Hello all - hoping someone can give me some direction. I have a 5 year old Rheem Prestige 96V unit. I turned on the heat for the first time last night - everything worked fine and hot air was blowing until the house warmed up. Woke up this morning and the furnace wasn't working. Bumped up the thermostat and nothing. When I check the furnace - I could see when it tried kicking the heat on (lower case h) and then would eventually throw the error code of 45. Thanks in advance!

If the installers left the installation manual behind, it will tell in there. That's the farthest I can go. I think I know what it is and if so, would need test equipment to find out of bad component or it's doing its job and flagged a problem.
