I'm starting to find your post confusing. In one post you say...

compressor fan stopped working.

Then in other posts you talk about the evap fan.

What fan is it that is not running for you?

Well, the condenser fan stops working when the compressor shuts off.  That doesn't usually last long, the condenser fan and compressor will turn back on, but, when they kick back on the evap fan doesn't turn on.  The evap fan started working this morning, but, then stopped when the fridge went into defrost mode then kicked back on.  Does that make sense?

With out a model number I can't say for sure, but I believe some older models had a thermostat connected to the evaporator fan. The coils would then have to get so cold first then the thermostat would close and then the evaporator fan would start to run.

This is all just a guess without being able to look up your model, but of coarse you can take it apart yourself, check voltages and follow wires to see what you got.

Mean while while the coils get cold all the food should that needs to be cooled will go bad, that seems like a really stupid set up.  He is a picture of what I am looking at.  It looks like someone put a defrost thermostat in there at some point.

I can't really see anything from your photo, it's so small.

I have not seen this type of set up for sometime now, but from what I remember the delay before the fan started running was not that long. Just long enough that you started to wonder if the fan was going to kick in or not and about the time you decided to take it apart to check things the fan started running...

In no way was the delay in starting the evap fan long enough to make food spoil.

Remove the bottom crisper bin to see if a model number is listed there.

On the Amana's the evaporator fan is wired through the defrost thermostat.  The fan won't turn on unless the defrost thermostat is closed.  So, if you're just starting up a warm fridge or it's just coming out of defrost, the fan is delayed a few minutes.

They want to wire it this way to get the evap really cold before starting the fan. GE has a similar wiring scheme.

So, in order to test if it is working properly.  I need to test the defrost thermostat and see if it is closed when the evap coils are cold.  Right?  If it is closed then I shouldn't get any continuity reading?  am I on the right track here?

Yes, that is correct.

If it's closed then you will get a reading of 0 ohms, just like if you touched the two meter test leads together.

Make sure when you check the defrost thermostat with your ohm meter that the refrigerator is unplugged and at least one lead on the defrost thermostat is disconnected.
