Englander 25-EP Exhaust Motor Issue

[wildguy]

I have a 6 y/o Englander 25-ep. My problem is the exhaust motor stops intermittently. Sometimes will run for 8 hours or more and sometimes for only 30 min before it stops. The strange thing is once the exhaust motor stops, I power the stove down "off button" and the exhaust motor will immediately come back on. No errors. I have replaced the exhaust motor and the board. Not sure where to go from here. Anyone else with similar problem?

I would check wires, wire connections, thermal sensor clean and connections tight, pressure switch, pressure switch tubing and venting.
