Error code EY (or5Y) ES.
Was recommended to place the main power board (under the front let side) used part number 241996320
Replaced the board yesterday and it started up and was running fine now late this morning it stopped again with the same error code.
What would you recommend next. The unit is 3 years old.

Hello
Look on the technical service data link below . The error codes you have cold be a few different issues Check wiring between evaporator fan and control board. Check for 12VDC to fan between red and brown wires. Check for variant voltage (depending on high or low speed) between yellow and brown. If correct replace evaporator fan. If error code still exist, replace control board. I know you already replaced the control board. Sometimes if the evaporator fan is drawing to much current it can damage the new board. In that case your board should be under warranty. Matt Ace technician
