I have a Rudd propain furnace and it is not igniting and the code lights on the unit are flashing twice and a 2 second pause. It is telling me it is a pressure switch is open on the main panel. Is this something a dyi person can fix and how do I fix it. Unit is 3 years old.

a blocked intake or exaust and a backed up drain will also cause a pressure switch fault
Yes! I CAN fix that!

Pressure switches are a real ease. Just be sure the power is off, that you match the replacement switch "pressure rating" and tubing connections correctly.

pressure switches are easy on ruud units there are two switches side by side if u are having a problem i suggest you change both the switches.. they are cheap and will save u alot of headaches... get in touch with your local ruud dealer and check with them because ruud had a recall on those switches.. i work on them on a daily basis u should follow my advice and your problems will be solved...
