Whirlpool Oven Error Code F02

The F02 code means the electronic control board has detected a welded, or stuck-closed, relay contact on one of the heating element circuits. The affected relay can no longer open to cut power to the bake, broil, or convection element. This fault is confirmed by checking continuity across the L1 supply terminals (P4-1 or P4-2) and the element connections (P5-1, P5-3, P5-4) with the oven unpowered. Because a welded relay can keep an element energized when the oven should be off, this code should be addressed promptly.

Resetting the power may temporarily clear the error code from the display, but it will not fix the underlying problem. If a relay contact is physically welded closed, the fault condition still exists and the code will return. A physical inspection and continuity test of the control board terminals is required to properly diagnose the issue.

Repair costs will vary depending on your specific model and labor rates in your area. A replacement electronic control board for a Whirlpool oven typically ranges from $150 to $400 or more for the part alone. If a heating element also needs to be replaced, parts costs will be higher. Professional labor to diagnose and complete the repair generally adds $100 to $200 on top of parts costs.

No, it is not safe to continue using the oven with an F02 error present. A welded relay means a heating element may remain powered even after you turn the oven off, creating a risk of overheating or fire. Disconnect power to the range at the breaker or by unplugging it until the fault has been properly diagnosed and repaired.

Start by disconnecting power to the range, then check continuity across P4-1 or P4-2 and each element terminal (P5-1 for broil, P5-3 for bake, P5-4 for convection). If continuity is present with the control unpowered, the relay on the electronic control board is confirmed to be welded shut. In most cases, the entire electronic control board will need to be replaced. You should also inspect the associated heating element for signs of shorting, since a failed element can be the root cause of the relay failure.
