The evaportator fan runs erratically.
Answer Hello. Check and make sure the fan is running at full speed, and not slowing down. It comes on to circulate the air inside the refrigerator. If the refrigerator is not coming on properly and keeping cool, then you may have a thermostat problem. Hope this helps.

How do I test my thermostat to see if it is bad?
Could a bad thermostat cause the drain hose to freeze up?
Answer Test the temperature inside the unit. If the temperature is correct, then the thermostat is ok. The drain hose needs to be cleared out, where water flows freely down it. If the freezer temperature is to cold, it can cause problems with the drain.

Replaced start/relay. It was bad. Have no power to compressor or fan but the lights come on.
The most likely cause for the unit to not come on and there be no power to the compressor would be the defrost control board. If you check for power across the orange and red on the control board there should be 120 vac. The compressor and fans go through the board 2304099.
The temperature control is turned all the way to its' coldest setting. The refrigerator is cool enough, but it should be colder given the setting. I have also found a great deal of frost in the back of the freezer. What would be causing this?
Answer Hello Cindy. It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the back wall of the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
tested the cold sensing thermostat as per your instructions and the meter went to 0 as suposed to. Then placed in a freezer for 30min. and tested the lowest setting;supposed to go to infinity according to instructions. Is it supposed to drop to infinity? it didn't move.Then I tested it at maximum cold setting(while still cold) and the needle didn't move.Warmed it up in the sun and tested 0 again. Normal or not? Driving me crazy.Frig runs ok till defrost then takes so long to come back on it gets to 50deg in frig part freezer gets to above 30. Thanks Al
Answer Al, It sounds more like a defrost timer or thermostat issue. But the cold control/thermostat has a preset temperature range and a "cut in" and "cut out" temp. range.The cold control will have a high(000)resistance or "closed" circuit, until the selected temperature is reached. The diaphram in the control will "open" causing the switch circuit to "open" (infinite resistance) "0" until the temperature reaches the "cut in" temperature and the circuit closes the switch, and repeats the process. You stated the temperatures and the refrigerator works fine, until the defrost cycle, that pretty much takes the temperature control out of the picture. The basic defrost cycle on a timer controlled system lasts approximately 26 minutes, from shut down to restart of the compressor, And the heater cycle will be active(on) for approximately 12 to 15 minutes, or until the thermostat opens and breaks the circuit. If the defrost thermostat, is "sticky" or the timer is "hanging up" this could cause the extension of the defrost cycle, an cause the freezer and refrigerator temps. to increase.
