Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.
I need the actual model number of your furnace. It on the rating tag inside the burner compartment
Ok, get me the info when you can b at the furnace to trouble shoot this. I'm online until ~7 pm EST. I do take breaks and I'll get back to you as soon as I can. If you want to troubleshoot later then just relist this question. Please do not pst a duplicate question
Ok, this is a draft pressure switch error so you need to check the exhaust vent for blockages, check the tubing connected to the switch (is it kinked, blocked , have water in it?), also check where the tubing connects to the furnace. You can poke a paper clip into the port where it connects to the furnace (not the switch). If you don't find anything you could have a bad switch or a weak draft inducer fan (is the fan running?)
If the inducer isn't running then nothing else matters. If he inducer doesn't run nothing else will happen. If you have no power to the inducer and you have a call for heat (jump thermostat R & W on the control board to be sure) and no voltage to the inducer then the board is suspect or you have a bad connection between the board and the inducer.
The blower should not run with a call for heat until the burners fire up. If there was an open limit error the inducer should also run so a bad board is a likely culprit.
Not likely and that's not relevant now with no power to the inducer
