Ariston Oven Error Code ER92

ER92 indicates a Key19 fault on the Ariston oven's touch control panel. The oven has detected that touch button number 19 is malfunctioning, either reading as stuck, unresponsive, or producing an abnormal signal. This is most often caused by condensation affecting the touch sensor, but can also result from a missing inductive rubber component or a failed display board.

A power reset, such as switching the oven off at the circuit breaker for a few minutes, may temporarily clear ER92 if moisture was the underlying cause and the panel has had time to dry. However, if the inductive rubber components are damaged or the display board has failed, the error will return after the reset and the underlying hardware issue must be resolved.

If the fault is caused by condensation, there is no parts cost involved. If the display board needs replacement, parts and labor costs can vary, but board replacements on touch-control ovens typically range from around $150 to $400 depending on the specific model and local labor rates. Getting a diagnosis from a qualified technician before ordering parts is recommended.

Start by opening the oven door and letting the control panel dry out for at least 20 to 30 minutes, as condensation is the most frequent cause. If the error clears, the oven can return to normal use. If ER92 persists, check that all inductive rubber pieces behind the touch panel are in place and correctly seated. If the fault still remains after these steps, the display board will need to be replaced.

ER92 indicates the touch control system has detected a fault, which can affect the oven's ability to correctly interpret commands. It is best to avoid using the oven until the fault is diagnosed and resolved, as a malfunctioning touch board could lead to unintended operation or an inability to control cooking functions reliably.
