Have E 22 fault code which I know is the fresh food fan. Problem is code will not reset and nothing else will start up on the unit. Can here the control board click but compressor never cuts on. Any ideas?

I would try to put the unit in diagnostic mode first. This model will store the errors. If you cannot get into diagnostic the only option is the main control board. Please let us know if this corrects the issue. Matt Ace technician

Are the lights coming on when the doors are open? If not plug something in to the outlet like a small lamp to make sure you have proper voltage. We use a Amprobe ST-102B Socket Tester with GFCI see link . http://www.amazon.com/Amprobe-ST-102B-Socket-Tester-GFCI/dp/B008E07HM2/ref=sr_1_1?ie=UTF8&qid=1439819835&sr=8-1&keywords=WALL+CIRCUIT+TESTER . If you have improper polarity or a bad neutral or ground you will also get error codes and a stalled unit that will be unresponsive. Did you unplug any wire harnesses? I would checked all the connections on the main control to make sure there is not a loose connection. If all of these items check out, I would try to put the unit in the diagnostic mode. See link below for diagnostic mode. If you cannot get into diagnostic mode you need to replace the main PCB board. Matt Ace technician

The lights do come on but that is all. I can hear the control board clicking and water dumps in the ice maker but then it stops there, nothing else. I cannot get any key to work on the dispenser it just blinks 22E so looks like a control board is in order.

E22 OR 22E This is a Refrigerator evaporator Fan motor error.
The fan usually stops working due to ice obstruction when the defrost terminator or sometimes called termination switch has gone out and u get ice build up? You can check the terminator with a multi meter for continuity but do not check at room temperature. stick the terminator in cup of ice water for 20 minutes then check it for continuity, should be closed when cold and open at room temperature. You also may just have a defective evaporator motor. If motor and terminator check out got to the cold control thermostat with a meter for both OHMS and volts ( VOLTS is a live test with fridge plugged in so be careful) It must show 110 volts. An open or thermostat that reads infinity will not allow the proper cooling and defrosting cycles to operate and may in fact stop anything from happening as if there is no power to the unit?
ALSO CHECK THE AIR FLOW VENT SYSTEM At times it can get stuck to far closed or open. Some units feature a digital electric adjusting vent system while others are manually set. Check for any ice build up or other obstruction in the vent damper, see if u can manually open or close it. Some times when u have the settings set to the highest it closes off one area while allowing to much cold air flow to the other area!
Hope this helps

The homeowners had the unit unplugged for a day when I had arrived…..according to them there was no ice build up. When I plugged the unit up I get the 22E code and nothing else will function, and I cannot get it to reset on the display. Where would I find the cold control on this unit as it is a dual cool with all digital setting I thought were control by the main board.
