Trouble shooting

■ Oven temperature rises too fast. [Electric malfunction]

Oven Temp 

 

rises to fast.

*  Check to see if oven exceeds 400℉(202℃)

with in 9 minutes of room temperature 

operation .

*  Check the harness connections at PCB 

terminals (RY201~RY204) and PCB 

connector(CN301) to make sure the  

harness does not have a short in it .

* Check the broil and bake burner operation .

END

* Repair or replace the harness .

* Replace the PCB .

*  Faulty broil & bake ignitor,
