Seven year old Frigidaire side by side will not cool. Approx. 2 weeks ago, it went stopped working & we had the relay replaced. The frig worked again for one week, and then stopped (the night it stopped we had a series of low power flashes, about every 5 minutes for maybe 3 hours). I was told it needed a new cold control & defrost timer unit so I replaced this part today, but still no go. The fan is on in the freezer section, interior lights work, but the compressor & compressor fan are not working. Any assistance appreciated. Thanks!

Thanks richappy. I believe I replaced the part you refer to. In the schematic, it was described as: "control -defrost, adaptive Timer, pc board". It's listed as part# 240545403 on the Frigidaire website, but I was provided with an updated part # 240554502. It is described on my bill simply as a "defrost timer". Did I replace the wrong part? I cannot locate the number you provided (AP3214257). Also, I notice now that there is a bit of insulation near the compressor that has been shredded or melted. Have never noted compressor to be hot however. Thanks again for your advice.
