Question and Answers

Q:

What does "F500 and "F20" fault codes mean?

A:

The "F500" fault code indicates a loss of communication between the Electronic Oven Control (EOC) and the Electronic Surface Element Control (ESEC). The technician would need to check the communication wire between P6 on EOC and P7 on the ESEC user interface board for loose connection or open circuit in the wire. If the wire and connection is OK and the fault code returns: 1. Replace the EOC. 2. Replace the User Interface Board (UIB). The "F20" fault code indicates the same failure.

I added an image below with the instructions on how to access the EOC and ESEC in order to check the wire connections at P6 and P7. Remove and clean the connection and then reassemble and check operation. NOTE: Disconnect or remove power to the range before removing the console.

I recommend calling a service technician to diagnose and repair your range.

Q:

Kenmore Elite Range 790.123400 F5-01 code after replacing all boards??

A:

Thank you for your question and I understand your concern.

The link Barbara H provided in the first response has some very good information. Installing the EOC kit #5304455004 should be installed to correct the issues.

When error code F501 appears in the display after replacing the Electronic Oven Control (EOC). The replacement EOC was modified to include updated software within the control, and will not communicate correctly with the original user interface board (UIB) and power relay board. The software was changed to improve performance.

The EOC Kit will contain the following components:

  • EOC/ Clock Timer
  • User Interface Board (UIB)
  • Power Relay Board
  • Instruction Sheet
  • Two Labels, (UIB, Power Relay)

I hope this is helpful. If I may be of further assistance as more details become available, please reply to this post.
