Thermador Oven Error Code F62

F62 indicates that the lower oven detected an over-temperature condition during a self-clean cycle. The control board monitors the lower cavity temperature through a sensor probe and triggers this fault when readings exceed the safe limit for the cleaning process. The oven shuts down the clean cycle automatically to prevent damage or a hazard. The fault must be diagnosed and resolved before the self-clean function can be used again.

You should not attempt to run another self-clean cycle until the cause of F62 has been identified and corrected. If the fault was triggered by an actual overheating event rather than a faulty sensor reading, using the oven in any mode could present a fire or safety risk. Normal baking may be possible in some cases, but it is best to have the oven inspected before resuming regular use.

Repair costs vary depending on which component has failed. A replacement temperature sensor typically runs in the range of $30 to $80 for the part, while an electronic control board replacement can cost between $150 and $400 or more for the part alone. Adding professional labor charges, a full repair could range from $150 to $600 or higher depending on the diagnosis. Getting a service estimate before authorizing repairs is always advisable.

Some steps, such as inspecting the temperature sensor and testing its resistance with a multimeter, are within reach for a knowledgeable DIYer who is comfortable working with appliances. However, diagnosing a stuck control board relay or replacing a thermal cutout involves working with internal components that carry high voltage risk, so professional service is strongly recommended for those repairs. If the temperature sensor tests out of specification, it is a relatively straightforward replacement part to install.

Resetting the oven by disconnecting power for a few minutes may clear the F62 code temporarily, but the fault will almost certainly return if the underlying cause has not been repaired. A stuck relay, failed sensor, or defective control board will continue to trigger the error under the same operating conditions. A reset should be treated as a diagnostic step rather than a fix.
