Hey all - new to this forum.

I have had a problem with my furnace (rheem chriterion ii). I narrowed the search to a (hopefully) defective pressure switch so I bought a replacement. My question is this: As you can see, on the current part, there are two wires with two different colors that come out of the switch from the side of the switch. The replacement is a bit different and has these two prongs coming from the back of the switch. Which wires go to which prongs? Sorry, the one photo came through upside down.

I verified with the company that i bought this from that it will fit my model #.

Thanks!

You know Max??

Max ( makes ) no difference.:biggrin2:

Rheem changes mounts occasionally and it is just a simple switch and has no polarity.

Where the red tube attaches to the furnace, remove it and poke the hole thru with a drill bit as they get dirt in there.
