checked bottom oven and customer said it will stop heating and the temp display goes to all 0's. Power on from a cold start and the display did go from 325 to all 000 but went back to 325. Burners come on and it heats. Moving the control panel cause the temp display to go to 0 briefly. The time display is not affected . Temp control is acting up. Called SOUTHBEND and talked to Charles and he said it needs a new control. Got part and price. Ok order the part per Curt. 9/27/19 Removed faulty temp control and installed new temp control board . Power on and unit heats to set point @ 350° F and cycled it 3 times and temp calibration is ok. Unit did not fail. Back in service
