What Does Monogram Oven Error Code F5 Mean?

The F5 error code on a Monogram oven or range indicates a loss of relay drive circuit on the electronic range control (ERC) board. The relay drive circuit is responsible for sending control signals to the heating element relays. When this circuit fails, the control board can no longer reliably switch heating elements.

Common Causes of the F5 Error Code

  • Failed relay drive circuit on ERC board – An internal component (transistor, driver IC, or trace) responsible for energizing the output relays has failed.
  • Failed output relay – The relay itself on the ERC board may have failed open or developed a high-resistance contact.
  • Power surge damage – Voltage spikes can damage the relay drive circuitry.

How to Troubleshoot the F5 Error Code

  1. Reset the oven – Power cycle via the circuit breaker for 5 minutes. F5 from a temporary glitch may clear with a longer reset.
  2. Test oven function after reset – Check if the bake and broil elements cycle on and off normally.
