I have a Fridgidaire side by side Model # FRS26R2AW4. It is thawed out in the morning but starts making ice again in the afternoon. I just put a new relay and plug and capacitor, run, 2 (ordered from you site). Plugged in and compressor and everything was running fine. Freezer cooled to 5.5 degrees. It satisfied itself, and temp is now at 40 degrees and it hasn't cut on again. It is making a "pinging" noise like it is trying to start back up. I have read on your site that it could be the defrost timer. (Is this the same as an ADC IV kit? If it is, the one in my fridge doesn't look the same as shown on your site. Mine is a white circuit board with a plug and 3 or 4 separate wires that plug on individual terminals. Your kit just shows one plug.)
I have read that the new ADC IV kit that you can order now, doesn't have the same number of wires as what is on the original. Also, does this come with a wiring diagram?
