The ice mager stop making ice, but I saw the froster on the pipe inside of the bin. I noticed that the exhaust fan for the compressor is not spinning, not sure if it is the issue.
You have frost on the pipe, that's good. It means the compressor and its charge of Freon is still OK. You didn't mention whether you had water flowing or not... I'll presume so. The fan by the compressor is crucial. It must be running in order for this unit to make ice. OK, you have removed the 4 screws holding the lower panel and removed the panel. The entire unit must be removed from the cabinet to proceed. Pull it out. *Take note of the drain hose, this may be difficult to re-install. After you have it out, unplug it, turn the water valve off and remove the cover off the back of the unit. Now reach in there with your hand and feel the blades on the fan, rotate them... do they rotate freely? If so, your condenser fan motor has failed and must be replaced. Getting to it... Go to the front of the unit, remove the two bolts holding the cabinet to the base. Then tilt the cabinet backwards, this will expose the problem child. (be careful not to bend/kink any copper tubing or wiring when you do this. And prop the cabinet so that it doesn't fall back down or fall all the way back.) Now, replace the fan motor with part #4387244, it can be purchased for about $70 at you local appliance parts store. Rebuild and you are good to go!

Here's how we test these...Completely remove the cutter grid, pull the plug on the water tank and let it drain so it runs empty.
Now, in "production" mode (water pump running) the evaporator plate (where the ice sheet forms) should begin to frost over fairly quickly beginning from the outside and working inward. This is good. There is a thermister (a temperature sensing device that communicates with the on board computer) beneath the evaporator, it will chill rapidly. When it reaches ~-2 degrees, the computer will initiate a "harvest". The time for the thermister to reach -2 is between 4 and 5 minutes.
If your computer never goes into harvest, and the evaporator plate is completely frosted over, you have a bad evaporator thermister. This is an easy repair, unplug the rear wire connector by the cutter grid on the right hand side. This is the thermister connector, by disconnecting it you set the computer to its' "default" harvest of every 20 minutes, period... regardless of the thermister problem.

OK, Now the fan is working, but it is still not making ice. It only has frost on the copper pipe inside of the bin. Except for not making ice, everything is good, the water is flowing and draining periodicaly, any suggestion ?
Thanks for the response. I checked the evaporator plate, it does not get frost after the water pumb is runing. The only frost I can get is from the copper pipe underneath the plate, and only part of the pipes is very cold with some ice and frost wrapped around it. Not sure what is the issue. This ice maker has been runnig ok for 4 years, never had any issue.
