Bob for Model Number PLRU1778ES0 Fridge cooling to 48 F on coldest setting. When I removed dial to check t'stat (216715503) I found a small screw next to dial shaft. When turning it counter-clockwise compressor started and c/w stopped it. Is this a control feature and how many turns would lower temp by 12-15 degrees? Thanks. Bob
Answer Bob, This set screw is for adjusting the temp but you will have to adjust it a little bit at a time to get it to the proper temp. You may not be able to adjust 10 to 12 degrees so it may be necessary to replace the temperature control. Read More... Answered by AppliancePartsPros.com | Tuesday, February 10, 2015
