No DIY advice. Call a professional. Do not attempt any other repairs yourself - you could hurt yourself, your family, or your equipment.
If you need help finding a contractor in your area. Use the contractor locator map on this site.

Why did you change the pressure switch? There are more false codes related to it being the pressure switch than any other, it's almost like when the board can't figure it out, it just says it the pressure switch.Originally Posted by nevets1215
