Bought a house with a Ashley 5660 US stove. Owner said is was recently broken. He ordered a controller board and it did not fix the issue. With the old board in there is no power/lights/ any signs of life except for the constant alarm from the speaker on the board. Attach new board and the fan and runs as well as the auger however no lights on the control board but it also constantly alarms. Tested fuses on power board and jumpered the over temp sensor. Ideas? Thanks
