Richard W Saint Joseph , IL August 16, 2015 The food in the lower crisper drawer was freezing The appliance repair technician showed me that the blue flab of this air vent was missing. He said that the part would cost about $150 so he put a piece of tape over it to limit the air flow. This might have worked fine but I had used AppliancePartsPros.com to keep a dishwasher going previously and checked what they wanted for the part. I found it available, affordable and had the factory like repair done in a few days. The part just snaps into place requiring no tools or skill!
