This is the little Blue relay down on the cooling deck. It is controlled by the motherboard and turns the compressor on and off. The compressor WILL NOT COOL OR EVEN COME ON unless the drink module is plugged into the Snack module and they both have power. The 901 control board has to be on and operating before it will tell the compressor to come on. This part is not used if you have a 243 control board, as it has mechanical Thermostat and Defrost Timer. (DLAA6583, DLAA6584) ***** If you unit is not cooling, go into the test mode on the 901 motherboard and try toggling the relay on and off. ( option tE Selection 3 ). A.) If the relay comes on, but the compressor does not then you probably have a problem with the compressor. B.) If the relay comes on and the compressor begins cooling, you probably have a problem with the Temperatre probe (The electronic thermostat built onto the motherboard.) (DLAA6574) C.) If the relay does not toggle, Ie the menu stays on ZERO or 0 then most likely this is the pieces that has gone out.
The relay may or may not say GOODSKY GU-SS-124DFS GUSS124DFS GUSS124
