2003 St Croix pellet stove. Have been getting a blinking 3 red light. Its been 5 weeks and no go. A new ciruit board, exhaust fan, pellet auger,4 POF switches and a new igniter. The 4 POF switches test just fine with the meter, tested each wire in the wiring harness and all have continuity ,put 900 dollars in new parts same blinking light. I put the button to the manual position. The pellets light and start to burn and the 3rd light blinks. Right after pellets start to burn I unhook the POF switch and put a jumper in. the heater blower starts to run and all works just fine. First time i had heat in weeks. Then as soon as i unhook the jumper and hook up the POF switch again number three blinks again. I just took the stove and blew it all out and exhaust pipe is clean also. I called and texted Even Temp and they dont answer or email back. Bought all new parts from east coast hearth. Had to buy a heated throw blanket just to sit in the front room. After all the new parts it should work fine. Thanks .Any help would be appreciated.
