foam block atop the compressor coil

M3 Pete · 07-15-2012, 12:36 PM

I took the cover off of my old Carrier compressor (38EB060350) yesterday to clean it out with a hose. On top of the coil (and maybe the bottom too) there is a 1x1 inch piece of black foam, to block air from coming between the coil and the top of the frame (so the air comes through the coil and not around it). The foam is crumbly and I lost quite a bit of it.

What is that foam called, and where can I get it? Can I use something else to replace it? I don't suppose I can use Great Stuff spray foam?

I know, I should have taken a photo but I did not. And I have not been able to find a diagram online that shows it.

Don't use great stuff anywhere near your coil.

Use thick weather stripping like you get for a window A/C.

strip of aluminum or galvanized sheet metal, from the local hardware, cut to size and held tight to top opening with heavy duty zip ties will do the trick too.
