Can anyone clarify how to check the pressure switch on a coleman model: DGAA056BDTB? I had one today that wasn't closing after booster motor came on. It has 2 pressure ports, one labeled + and one -. Its rated at -0.15, I put my manometer onto the 2 ports and got a reading of -0.30. So i went to get a pressure switch but when i got back, the unit started working again. I changed the switch anyway but I dont know for sure if i diagnosed it properly. When taking a manometer reading, should i measure only the negative hose? Also, side question, does it matter which hose i put on the negative and positive, or is it just a differential that the switch needs to close? Ive never found a bad pressure switch and i know that they very rarely go bad. Thanks fellas!
