I reset. Still two lights flashing after 45 seconds.
Yes still same code I removed 1 and tested and then the other. Reconnecting previous.
I was finally able to get multi meter and tested pressure switch. Checked out.
I also turned on furnace and blew switch open. The furnace fired up, but as soon as I put hose back Furnace shut off.
Is there any other test for circuit board being faulty.
I would hate to send for part and find it was not the problem.
they run about $125
I agree with Phil. Replace the board. I read all of his troubleshooting and he led you down the right path. Please remember that an expert is not always right but if they know more than you you should take the advice. Also remember to rate his help.
Yes it did. I also cleaned combustion motor and furnace is working perfectly.
I just finished installing this afternoon Great timing.
Thank you for your help.
You are welcome and I will pass the word along to Phil. One more thing, would you please finish the process by rating my help.
I look forward to helping in the future if need be.
