Help!  I have a Whirlpool 'side by side' (model ED25RFXFW) that is about 7 years old.  The freezer and refrigerator are approximately the same temp. - 58 deg F.  The evaporator fan is NOT running; compressor runs continously and is pretty dang warm.  The condenser fan is running. 

The unit started to give me fits yesterday; I checked the evaporator coils, and they had very little frost.  The unit was unplugged for about 3 hours.  When I plugged it in, she started to cool just fine and I even had fresh ice this morning.  When I got home from work, it was apparent the evaporator fan was off and the unit was cool (58F as noted above).

Obviously, the lack of an evaporator fan is not good.  Any way I can verify that is the culprit?

Thanks!

After removing the evaporator cover in the back of the freezer to expose the evaporator fan, I plugged in the unit and turned it on.  The evaporator fan was making a slight hum.  I turned the fan blades and it started up; seems like something got hung up or my motor is going out. 

The unit is up and running, but I think I am going to replace the evaporator fan as it is relatively low cost compared to food potentially going to waste. 

The compressor was pretty warm when I turned the unit off a couple of hours ago; could a bad evaporator fan cause compressor damage?  I wouldn't think so, but I am a rookie...

Thanks...

The evaporator fan motor will quit on you again. Once they start doing that, they'll keep doing it, especially when the box pulls down to normal freezer temps. You can buy your replacement here: http://www.repairclinic.com/referral.asp?R=154&P=69

Update: The evaporator fan is working, but it doesn't sound so good.  As I noted above, I am in the process of ordering a new fan and installing it. 

Question:  I didn't put the cover over the evaporator coils (on the back of the freezer wall) but am running the refrigerator.  Since the fan gets hung up (and since I am going to replace it) I thought I would keep the cover off to keep the fan running.  However, the unit is not getting down to temperature (freezer about 20F and frig at 40F after ~12 hrs).  I assume this is because the rear cover is removed and the air flow is not forced accross the entire evaporator coil.  Is this a correct assumption?

The coils got nice and frosty overnight and the defrost cycle worked like a champ this morning.  So I am hoping the evaporator fan is my only problemo. 

Thanks...

Yes, the cover channels the air intake for the fan to pull the air across the coils. Without the panel in place, air will simply take the path of least resistance into the fan.

And, if you're hearing fan noise, the evap fan is probably not running at full speed and so is not moving the design volumetric flow rate of air.

with out the back panel in place and air flow not going over the evp.coil you should have a good frost pattern if you wett your finger and put it on the coil it should stick to the coil this is a good test but does not confirm temp to be 5 degrees.if you do not have a good frost pattern check on condenser fan operation.also check and see if condener is clean just helping cdwasher.

FYI - just to close the loop on this problemo. 

Frost pattern was good.  Condenser is clean and all else appeared good.  I replaced the evaporator fan motor and the unit works great - holds the freezer at -4 F and the fridge at 33 F at the mid-settings (damper between the freezer & fridge half open and the temperature control nob at the middle setting).  I should note the unit is much quieter.  The unit was steadily making more noise until the fan intermittently stopped working. 

Thanks again for your help!
