Identification
Different Whirlpool Gold models display error codes in different orders, but they mean the same thing. On your oven you will see either "E1 F5" or "F5 E1." Both errors address the same problem.
Effects
The "E1 F5" error code is a door switch malfunction. This may display if the door is not shut properly, if it is jammed or if the spring-loaded mechanism has broken.
Considerations
Try opening the oven door and shutting it while putting pressure on the center of the switch until you hear a click. Jiggle the latch to try and reposition it so that it shuts properly. Examine the latch to make sure it is properly attached.
Prevention/Solution
If none of those methods remove the error, you may need to replace the door latch. Visit the Whirlpool customer service website to find the correct part you need.
