How did you test the pressure switch? Are you using a vacuum gauge to determine inducer is pulling sufficient vacuum and that switch is indeed closing/
OK if you have proved the switch really is closing, make sure connections are clean and secure on board.If so it sounds like we have a bad board, not sensing the pressure switch is closed.
I totally understand that.I am a Rheem/Ruud dealer and am more than happy to guide in troubleshooting if switch was not closing to determine why, but if we know it is, but board says it is not, there is not much troubleshooting left.
If you need help finding best price on board give me model on furnace and I will be happy to help you do so.
Unfortunately there is no way to bypass .If it were a limit we could (although not recommended), but the board is the brain. It has to sense pressure switch is open before it will allow inducer and furnace sequence to start and then it has to sense it closed before it will allow ignitor and gas valve to open.
model should be inside furnace in burner compartment so I can provide guidance with this specific unit.Model will be on a label just above burners on right or left inside panel
That loos more like serial. Model should begin with letter R such as RHGPp7EAUER
Looks like Rheem used a couple of different controls on this model. Tell me if perhaps the 8th digit is first number you gave me might be an F instead of a 5
The most common is the 62-24084-02, Can you see if that number is ***** on your board?
You can Google that part number 62-241136-03 to find best price.
Wish I had better news, but I do appreciate you allowing me to work with you.Follow up is appreciated
