FD used rotary compressors till the end around 1980 But they did become more powerful in the larger refs around 1966 so they worked better. You may be able to install the later compressors in earlier models with a good deal of work, relays were generally different for different compressors.
If I were going to try to use and save one of these older FD FP refs that could benefit from a better larger capacity compressor I would use a 5-10 YO Embraco compressor from a GE or WP built ref, these newer compressors are far more efficient quieter and longer lasting that those old FD compressors.
I have an early 80s WP built upright freezer where we took out the R-12 rotary compressor and used an Embraco compressor [ R-134A ] and condenser assembly from a 5YO GE SXS and it works great, you barely hear it running and the freezer when running including inside fan draws less than 150 watts.

Thanks!! So is the 1966 version still a rotary compressor with the same internal design as the earlier Meter Miser? Why would it use a different relay I wonder? | ||

Frigidaire Demand Defrost System 1967 Hi Juke, Frigidaire tried some sort of demand defrost system for about one year and probably on one model and it seems you have one.
My limited understanding of this system was that there was no defrost timer at all or this system was at least designed to start the defrost cycle based on a combination of evaporator temperature and condenser temperature.
I need to go dig through my FD service manuals and see if I can find information about this interesting ref defrost system, thanks for bring this up, I had only ever seen one of these refs and it was about 35 years ago.
