Hello all......researched, read the forums.......now it's my time.
Freezer quit cooling, fridge was not so cold. Let it thaw, two days worth.
I cleaned every coil, every spot, better than new.
Plugged it in, condenser kicked on, coils started frosting up, crossed my fingers, but no fan......
I guess I can assume from all I have read a new fan and board is in my future? Very handy, but not so much with multi-meters.....it's my own personal shame.
Any way to confirm I need the fan and board, or is there simply enough history with this model(s) to assume that's the case?
Thanks to all.

You probably don't need to replace both. If the fan test bad the the board could be ok. It would be worth the10 dollars or so and learn to use the meter.
For the condenser fan near the compressor. Spin the fan blade, it should move smoothly and freely. If the fan does not move smoothly, replace the fan motor. Test the fan motor for continuity using a multitester. Set the multitester to the ohms setting X10. Place a probe on each terminal. In the photo below there are three terminals, the middle one is for ground and does not need to be tested. The multitester should display a reading approximately mid-way between infinity and zero ohms. If the motor does not pass this test, it should be replaced. For the evaporator fan i the freezer: Spin the fan blade, it should move smoothly and freely. If the movement is not smooth, the motor should be replaced. For the evaporator fan in the freezer: Test the fan for continuity using a multitester. Set the multitester to the ohms setting X1. Place a probe on each terminal. The multitester should display a reading of zero ohms. If the fan does not pass this test, it should be replaced.

First, thanks for the thorough reply to my posting.....at 43, I have tried through the years to get proficient with the multimeter, sometimes with more reliable results than others. I will keep trying........it is my white whale.
I may have made the rookie mistake.
When I said the fan didn't engage, I was referencing the fan inside the freezer, the "evaporator fan". My apologies for any confusion.
The "condensor fan" kicked right on, the coils in the freezer began getting cool and starting to lightly frost, I took that as a good sign. I figured the defrosting process with ambiant air temperature and a short time with a hair dryer required the system to fully cool before the evaporator fan kicked on. I knew better, but it was my only hope.
So......with that in mind, everything seems to be fully operational, except the evaporator fan. I did remove the evaporator fan from the freezer, and tried the multimeter on the four wires that exited the fan. I placed a test probe on one of the wires and placed the other probe on the other three, each resulted in a number of 15 to 20 (this is where it gets sketchy....I don't know what setting I had the multimeter, the 15 to 20 is based on memeory from last night as i am currently in the office. I will try this again later today).
A note that I should have added previously (I saw mention of this in other postings), the evaporator fan was noisy at random times over the last few months. I assumed minor ice build up on the fan, but found none. From what I see in other postings, this may indicate a variable speed / voltage issue from the main board?
I don't like throwing money out the window or into a freezer without some reason for doing so, but the price of the fan and board is not crazy and would certainly be justified to stop dealing with life without a refridgerator. Yes, life as a bachelor has its priviliges, but the girlfriend is coming over this weekend, so I need resolution.
Any thoughts?
Thanks again.
