Checking Furnace Pressure Switches

[@gilbertopatino2616]

Thank you very much for a great video 👍

[@johnaries9301]

Can you wire a pressure switch backwards?

[@TECTubefilms]

switches are not polarity sensitive. they simply break the connection

What is the function of the yellow pressure hose?

[@TECTubefilms]

Which yellow hose? There is one on P1 and one on Pump in this video. Dave explains how to use in the video. Is there a more specific question you have?

[@bjams]

@@TECTubefilms Sorry, I mean the yellow pressure hose that is in the background. I believe it’s called the “condensate trap relief port” hose. I know that it connects one relief port to the other, but I haven’t been able to find any explanation for why that is necessary (or what might happen if it wasn’t there).

I believe the yellow breaks a vacuum between the drain box and the secondary heat exchanger

your hands are in the way the whole time

[@jongreenbaum250]

Can't see where you are checking the voltage. Your hand is in the way.

[@TECTubefilms]

It is a pressure switch video... He stated to check the voltage through the switch. There isn't much space there for Dave's beat up 'ol grabbers and show where, so he was very clear as to where to measure voltage in the beginning. Through the switch.

[@jongreenbaum250]

@@TECTubefilms You are assuming we all know how/where to measure voltage "through the switch." I don't know where to put the probes. If I knew this stuff I wouldn't need the video.

[@ryanhoger1]

A pressure switch in a furnace only has two terminals so when you test voltage or continuity "across" a switch... any switch... you put one probe on each terminal.

I have a Bryant 96% inducer motor with speed fluctuations 912SD42060 E17A - A I have a video to share let me know how to send the video

[@TECTubefilms]

Not sure what you mean. You should share your videos on your own KZbin account for your followers. This channel is just for our followers.

Nice stuff. Im 672 ABC .. I use these.

Nice video ! Please keep them coming out. Thanks.

Nice video. Thank you 👍👍👍

It was ok , yet your hands were in the Way to observe the actual connections ....!

[@jessemotola2763]

Guy just rambles. He says pressure switch 100 times. Can’t see where his hands are going. It’s scary these are the videos our new guys are watching
