GE side by side 33 years old, TFF24RCB. Compressor stopped running, cycled and clicked, unplugged. Did some research, found both the relay and gaurdette are NLA, so I bought a Supco 410 hard start, and waited for my electrically savvy friend to have time to look at it.. Relay appeared to have failed, no engagement for start, so no start when run voltage present.Installed the hard start, compressor started right up and fridge cooled down "close" to spec, maybe 5F higher than expected from diagram.
Problems are running too long, but does cycle, front face next to door seal is hot, about 125F. All accessible coils and air path brushed out and vacuumed prior to fix.
Relay WR7X138 and Gaurdette WR8X44 are both NLA, but IC102 has been suggested as a replacement relay, no idea on Guardette replacement, but it sure looks like a common part.
Hard start has C, M, S that goes to compressor, and two black wires that were connected with wire nuts to the 3 wires from the fridge harness. Originally the condenser fan connected to temp control out on one end and between compressor and gaurdette on other end. Not possible with 3n1 hardstart as the thermal overload is internal, but pretty sure it was or has been running.
Thanks.
