There's a piece of sheet metal lying directly on the coils of the freezer compartment of my GE PDS18SBMALBS. Is that right? I can't tell from the parts diagram.
Sheet metal in bottom-freezer refrigerator

Hi Wendy, there is an aluminum sheet laying directly on the evaporator of your refrigerator, that’s the way it was built and needs to stay
The aluminum helps trap the heat from the heater in the middle of the evaporator that defrosts it. It also protects the Styrofoam insulation above the aluminum sheet from the intense heat of the red hot heating element.
This aluminum sheet is very important not only makes the evaporator defrost properly, but also protects the plastic parts above the evaporator from severe damage from heat or possible fire.

Thanks a lot for confirming that; makes sense. I'm out of things to try to keep the crisper drawers from running too cold--things at the bottom of both drawers start to freeze, although higher up in the drawers is OK. I suppose something is wrong with the airflow, but I'll be damned if I can figure out what it is.
Hi Wendy, can you post a picture of the insulation you’ve added above the plastic floor of the refrigerator?
I’ve had many customers with the problem of freezing stuff in the crisper drawers at the bottom and we’ve always been able to solve it by adding adequate insulation sheet, there’s just no way things are still gonna freeze if you insulate it properly

Hi, What's the R value of that insulation sheet, my guess is that you may need 2 or 3 layers of that insulation sheet.
We have usually used a flexible closed cell foam at least 1/2" thick

I don't remember the R value, but it can't be very high because it's quite thin. In fact, I actually do have three layers folded. By flexible closed cell foam I take it you mean something like pipe wrap but flat. I could try that.
I notice cold air escaping from the sides and back of the Styrofoam under the FF floor. Should I block all that in as best I can with strips of Styrofoam or the closed cell foam? And I wonder if as a last resort I could raise the drawers one notch by raising the shelf they hang off of. A small waste of space, but if it lets the drawers be in use again....
Thanks for your ideas and expertise.

Could you possibly point me to the kind of insulation you're recommending at, say, Lowe's or Home Depot or Ace Hardware, all of which would be easiest for me to pick something up quickly? Thanks again, in advance this time.
