The infrared images of the frig compressor showed alot of  heat is generated 

Here in an older photo is the same compartment.

The exhaust air for the cooling air looked pretty warm also. 

The air flow - through the closed drawer and a fan pushes the air into the compressor compartment - the air flows up and into the cabinet.  see above. 

I noticed that when I opened the drawer the hot air flowing out increased.  

I've added a vent as seen below - there is a large gap for the air to flow around the drawer and into the compressor compartment. 

I'm not expecting a huge drop in running frig time but I'm hoping for more effective cooling by the compressor and thus less energy usage.
