No- the first systems you checked were
1. the air distribution system (“not hearing the evap fan motor”)
2. the refrigeration system (“put ear against fridge to listen for any humming”)Then if the first system I checked was the air distribution system, then you are wrong too, because the correct answer you grade is the refrigeration system.
Which confirms my point that your question needs to be more precise, you yourself just disagreed with your exam.
Since the temperature control system controls when the refrigeration system operates, it is absolutely necessary for me to confirm the unit is calling for cooling before bothering to test if all the refrigeration system components are operating.
Let me try it this way, responding to a warm fridge and freezer, and remember, the idea is to be as efficient as possible.
Your way: I pull the fridge, which always presents a risk of floor damage regardless of precautions, remove the machine compartment cover, and see that the compressor is not running, and its room temperature. But the condenser fan motor isn’t running either. Since im here, ill check that i have power to the cabinet, and i do, but no power to neither the compressor nor the CFM. Nothing else to check since there are no other components back here. Furthermore, not going to bother testing the compressor since the issue i see right now, is there is no power being supplied to it. So I push the fridge back, open up the freezer door, and discover there is no evaporator fan motor running. I open up the refrigerator door, and i tap on the cold control, and low and behold, the fridge kicks on. I had to check the refrigeration system and then the temperature control system.
My way: I open up freezer door, not hearing the evap fan motor, i close door, put ear against fridge to listen for any humming. When i dont hear any humming, i tap on cold control, and fridge kicks to life. First system i checked was the temperature control system
This happens on almost any side by side whirlpool/kitchenaid that uses a 2198202 cold control. Now, the compressor is not running, correct? but since the refrigerator is not running, or calling for cooling, i would not expect the compressor to be running since the unit is not. So why would i waste my time pulling the fridge out to check the compressor when the refrigerator is not running?
So, my point of the whole post here, is that you need to be specific in your question, i.e., you need to specify that the refrigerator is actually calling for cooling in the situation you present. You only state that both compartments are warm.
Tell me how your way is more efficient?
What I mean is that checking to see if the compressor is running, doesnt tell me if it SHOULD be running. The only way to know if it should be running is to check the temperature control system to see if the unit is calling for cooling.
If I see a warm refrigerator and freezer compartment, the first thing i check is not going to be if the compressor is running. The first thing I check is if the refrigerator is running. Do I hear the evaporator fan motor in the freezer, or do i hear/see/feel warm air from condenser fan motor. If I dont hear any motors, or put another way, if i dont hear the refrigerator running, checking to see if the compressor is running is pointless, i already know its not, why pull the fridge to check something i already know.
I need to know that the refrigerator should be running first, so i would first check the temperature control system, then i check the defrost system. Once I know the unit is in refrigeration cycle, THEN i would check to see if compessor is running.
