At first we noticed that the frige would start the fan and it would go off again and then it would retry for a couple of times and then it would work till it shut off. Next time it would do the same actions, but now it just turns on then off, repeat, repeat repeat. We call a repair person and they said it was the temp control for the freezer (temp for the freezer seemed to be fine the whole time) He replaced that and frige still had same problem. Talked to another repair person and he said that it was most likely the evap. fan motor. He also said that sometimes is the motor goes bad that it will take out the control board. We replaced the evap. motor yesterday...nice and quite, but it is still tuning on and off. Just want to see if it could be anything else besides the control board as I don't really want to just keep throwing parts in the frige.
Please help.:confused:

Check the back of the fridg, does the compressor turn off when the evaporator motor turns off. If not, you probably have an intermittent wire to the evaporator motor.

The compressor doesn't seem to be affected by the evap. motor turning on and off. If I have the door open to the fridge for a little while then the evap. motor will kick on until( I'm assuming) the temp gets back to what the temp control is set at and then it will start cycling the fan on and off. There is no delay between it turning on and off once it reaches the desired temp in the frige.

Sure seems like a bad wire to the evaporator motor. To verify, get a voltmeter and verify the motor voltage is lost when the motor stops.

Having same problem, evap fan motor starts and stops, compressor running fine and fridge and freezer still cool and cold. Was it the control board (adaptive defrost control) or something else?

Amana SRD22S5E. Evap fan will run continuously for a while, then start and stop every 1-3 seconds for another while, then run continously again for a while before the compressor turns off. I can't hear any strange noises like the fan blades hitting ice, just seems like power to the fan is being cut off and on in the middle of its cycle.

You have a simple, mechanical cold control in this, most probably a bad/burnt wire to the evaporator motor.

Can you tell me what the cure was? My frige doing same. Evap motor starts and stops every 3 seconds, then runs a while. This all started after replacing start relay on compressor.
Frige started getting warm but freezer was fine.
Checked and found evaporator iced over. Thawed and everything normal till frige got to temp, then started with fan thing again.
The funny thing is, when evap was iced over, the fan was running constantly.
