did you check the heater at the bottom of the coil (evaporator)

Check continuity on the heater leads. Pay attention to the wires on the leads. I have seen them get loose and come off.

let,s start over, you say the coils are iceing up, does this mean there ice or snow? if there ice this may not be a defrosting problem it may be a drain problem ,on the model # i did not see a drain trough heater make sure there is no service flashes on this problem . Make sure the drain is completely clear. Then we go from there.
