How to replace high pressure switch on Lennox A/C

[@brainkill7034]

3:20 - you’re not putting much tension on the cables which is good, but you’re scraping it against the edge of the aluminum which is a quick way to shred the shielding. Keep a shop towel with you and you can place it in between the cables and condenser and not have to worry about it. Can also use it to protect your hands when removing the fan and dealing with other sharp edges, but I see you’re wearing gloves. Could be a nice alternative to gloves when it’s really hot out. Just a thought. Nice video, thank you for sharing!

Thanks for your video but Your audio recording in the field is terrible, with very low volume and quality.

Why do those low pressure switches go out? I'm dealing with the same issue low pressure switch stop working.

[@hvacculture]

Good question, everything breaks and this is not an exception.

I definitely feel like I’m being conned by my local HVAC company. They are charging me $400 for the switch and $600 for the refrigerant. WOW.

@@james4wbhsbasketball yeah, that sounds too much, where are you located?

[@ericanos9465]

bro the condensor was a blanket of dirt on it no wonder its going on high pressure lol

[@hvacculture]

The unit wasn't going on high pressure. I agree that condenser is very dirty but there is no way it will get to 600psi to trip that sensor just because of dirt. That sensor designed for any major issues like restriction in refrigeration circuit for example that might cause extremely high pressure but definitely not to go off on dirty condensers.
