Schwarfa for Model Number ERD36SBK Hello, the display has gone blank. What is difference between relay board and control board? Not sure which part to order. Thank you.
Answer Schwarfa, the relay board is responsible for relaying power to the clock/display control as well as the oven elements while the control is responsible for "communicating" information to the relay board on what relays to activate. If you access the control and test pin 14 and 15 at the connection coming from the relay board, you should have 24VAC coming from the relay board. If there is 24VAC, then you would replace the clock control. If there is not 24VAC, then you would check the wiring harness and if the wiring is good, you will want to replace the relay board.
