Maytag Oven Error Code F5

F5 on a Maytag oven means the control board has disabled power to the element relays while in cook mode. This is a protective fault that prevents the heating elements from operating when the control system detects an abnormal condition. The cause is typically an intermittent problem with the temperature sensor, the wire harness, or the power relay board.

The F5 code indicates the oven has already disabled the heating elements as a protective measure, so the oven will not heat normally while the fault is active. Attempting to use the oven in this state is not recommended since the underlying electrical issue has not been resolved. The oven should be inspected and repaired before returning it to regular use.

Repair costs vary depending on which component is at fault. A replacement oven temperature sensor typically runs in the range of $20 to $60 for the part alone, while a power relay board can cost anywhere from $50 to $150 or more depending on the model. Adding professional labor, total repair costs commonly fall between $100 and $300, though complex wiring repairs or hard-to-find parts can push costs higher.

Some causes of F5, like a loose wire harness connection, can be addressed by a knowledgeable DIYer who is comfortable working with appliance wiring after disconnecting power. However, diagnosing an intermittent fault on the power relay board or replacing the temperature sensor requires more technical skill and familiarity with multimeter testing. If you are not confident working inside the oven's electrical system, a qualified technician is the safer choice.

Resetting the oven by disconnecting power for several minutes may temporarily clear the F5 code, but it will not fix the underlying problem. Because this fault is often caused by an intermittent issue, the code is likely to return once the oven is back in cook mode and the faulty condition reoccurs. A proper diagnosis of the sensor, wiring harness, and power relay board is needed for a lasting repair.
