Mark W Prescott Valley , AZ November 05, 2016 Appliance: Frigidaire Frg/Freezer MFU17M3GW2 Frigidaire Freezer Mfu17m3gw2: Freezer shutting down by itself. How to replace Control - Temperature. I read a couple of similar symptoms on the Appliance Parts Pro website and determined it must be the Temp control. The compressor AND the defrost units were on simultaneously and i knew that wasn't right. I ordered a new temp control, installed it in 10 minutes and the freezer seems to be operating just fine. At 15 years old I hated to replace it, so glad this worked. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
