Condensate drain, very prone to leaking inside the cabinet. Picture 2 shows corrosion, did you pull the cover?

Thank you. What does it do? it looks like it has a plunger switch.
Sure did. I was hanging on to the trusses for dear life and standing on the V’s, no proper flooring in front of the unit. Rust stains was because a vent pipe above had a slow drip, had to be condensation. Thank you.[quote=“sbaker2, post:3, topic:194701, full:true”]

It’s a drain trap.

I’m not sure of the furnace brand and different manufacturers use different condensate drain traps.
That red part may be a connection for another drain hose location when the furnace is mounted in the vertical position.
When you have time, look up the model number and installation instructions just to become familiar.

I couldn’t tell the amount of “work space” from the photos so I thought I’d share this info on accessibility, just in case:
