Can I remove this whole house fan grate to replace with drywall?

We’re losing a lot of air through this old whole house fan. I checked it with my infrared thermometer last night, and at 9pm, the metal was still 87 degrees.
I don’t want to go through the process of dismantling the entire fan, but I also don’t want the thing collapsing into me if I remove the grate.
Plan is to drywall it with some insulation.
Edit - whole house fan doesn’t work

A simple [temporary?] solution to improve your situation is just install insulation on top of the grating. Go in the attic and look to see if this might work.
Then in the fall, when it is much cooler, you take down the grating and install sheetrock.

If that whole house fan is still functional, why not get in the attic and insulate it from the top with a bit of batt insulation that you'd use in ceilings.
Then when fall and spring temperatures are conducive for it, use the whole house fan to cool your house and get some fresh air circulating throughout the house.
If I had a functioning whole house attic fan already installed, I'd not want to disable it in any way.

nothing to it at all, drop the grill, cut foam board to size to fill snugly just inside the hole, then stick it in and then put the sheetrock in and its done. finish by going in attic and stuff the hole with fiberglass and safely disconnect any wires still going to it. ours has been closed in like this for 20 yrs now without issue.
we thought about taking it out completely but its a heavy bitch and they really arent worth anything to resell but it sure would be nice to have something like it in the garage area in summer

We used to remove those every chance we got, and father in law would make awesome patio fans out of them. Much better than the ones available at the big box stores.
But to your question, like keakar said, the grate is not structural at all. Remove, insulate, and drywall.

Don’t just try to cover it with insulation, remove it. Hot air leakage through the vents is the major issue. Sealing the area wil do more to lower the temperature than just putting insulation. I learned this the hard way, seal air leaks first then insulate.

We had one. Replaced with an attic ladder.
