Hi,Welcome to Just Answer, My name isXXXXX will be helping you with your appliance issue today.
this has two compressors in it, they are in the top where you cleaned the condensor coils the one on the right ride is the fresh food comnpressor, is it running? is it warm, hot, or cold ? does it vibrate?
its probably in a defrost cycle right now but the compressor should be warm, its not running, the smaller one is for the refrigerator, this could be a number of issues it may have a bad start relay or a bad cold control or the compressor itself could have failed, you would need a voltmeter and wait for this to come back on and test for voltage to the smaller compressor at the relay, these are difficult to work on and I'm not sure if you have the tools for that, usually if you don't have the correct tools it's best to call a technician to look at this, they would also have the relay with them most likely if that's what it is., We see that a lot, the first step is to see if the compressor is getting power, if it is and it's not starting the relay is probably failed, I'm sending you a link to the diagram, hope this helps, thanks, Bryan,
