9371DO-HS-0031 - Coleman OEM Furnace Replacement Air Pressure Switch

Had the old one go out the light was flashing 3 times got. this I ordered this one and it went in very easy and works great. Did not have to call out a AC repair company so it saved me a lot of time and money.

This worked great! Make sure your hoses are connected in the right configuration

Old pressure switch failed. This one works. Flow direction would be helpful. Had to swap inlet and outlet tubing. Easy enough, just had to move the switch because tubing was too short.

My furnace stopped working and the light on it was flashing 3 times, indicating the combustian air flow switch failed to close. My old switch would work if I blew through the right hose at the right time and I could hear it click and my furnace would then allow the ignighter to heat up and it fired and I had heat. I ordered this replacement unit which has slightley larger breathing holes in it. I was slightly weiry but the info said it was the right replacement for my old switch. It was easy to install with the instructions supplied and now my furnace works fine. I also saved a bunch of money doing it myself.

This fit my Coleman furnace exactly that wasn't the exact one that was in there but it came instructions to be an exact replacement I am a heater Tech so I wanted to go back with the exact one that was in there but this is an upgrade and it works fantastic

Should have 2 hoses but only had one

I ordered this as a direct replacement for my OEM switch and it does not work in my furnace.

I’ll buy again if needed. Good price. Quick delivery.
