It seems to be getting in from all the knockouts and around the inspection access doors. I have been sealing every hole with foil tape i can find in the trouble units i run into. Once i do this and put thicker gasket material on the top of the door it seems to be helping. The last one i had tripped the unit breaker and the 200 amp panel breaker. there was a 4"diameter hole on the control board.

Had a building with 18 green carrier weather makers with that awful giant panel that warps and fits rough and you need to zap self tapers into the panel so "snow" doesn't get in.

It is designed to be outside. We have ALOT of war time homes in my area. A lot of people have RTU beside their house on the ground and I have never seen snow inside panel. That's with snow drifts blocking the venter motor .

Maybe I'm lucky or you guys are just unlucky LoL

Where is it getting in?

Hahaha. I'm right there with you. I've seen rain get in through panels that were on but that's another story

Wherever it can.

Have had numerous Trane rtu's this winter with this issue, enough to cause tripped main breakers, have had to get heat gun out and dry electical.

Congrats,, I am looking forward to that.

The HX on those units shouldn't crack after 5 years either.... But they do!

Don't know about carrier, but some manufacturers offer an optional snow kit to prevent it from blowing in

Once last winter for me.

The new ones have a seal at the top of the door to prevent this.

Snow and wind and Carriers don't mix.

Snow in carrier 48tj electrical compartment

Has anyone else run into issues with these units getting snow in them. I have run into about 3 already this winter and have repaired many in the past years.
