    That's sweet I just saw the same thing yesterday. Service sticker had something on there about once a year for the past 5 years or so about checking press switches, clearing drains, etc.

    Looks like a Rheem pressure switch on a Carrier Furnace... The wrong pressure spec. Not all hockey pucks are the same.

    The one I was on had a .6 single port to the collector box. The tube from the tee was just tucked behind the switch. People amaze me.

    Yeah lol. The sad thing is it was only my company stickers on the furnace. Makes me look like a jerk.

    Yep, that's why I was there. I just followed the stream to the furnace.

    Thought it looked familiar. PITA to work on. Carrier never puts the make or break specs on their P/S's.

    Any tips or customized tools for getting the flame rod in and out when the intake is on the left and the pvc is butting up against a return or gas line?


    Also, I'm thinking of carrying my gallo gun for a quick and easy way to blow out the lines and trap for Carrier 90's on PM's. See any issues with this?

    I'm also hoping to be at the very end of my working days before all I am confronted with are 90 percenters. I awoke covered in sweat in the wee hours the other morning, having had a nightmare about a horizontal 90% in a tight attic, mounted a foot in the air with a drain pan sticking out 15" all around...

    Good one!

    For that I am glad to be south of that line!

    Had an issue with a Lennox G32 the exhaust fan had a mouse stuck in the fan wheel, never saw this in a condensing furnace. Found a nest in the exhaust pipe solidly made out of dog hair, smart SOB mouse, except not smart enough to stop before the big drop into the wheel of death.
