Ariston Oven Error Code ER07

ER07 means the NTC thermistor on the oven's power supply board has detected that the board is overheating. The oven shuts down automatically to prevent damage to its electronic components. This is a thermal protection response and not a cooking sensor fault. The condition must be investigated and corrected before the oven can resume normal operation.

No, you should not continue using the oven while ER07 is active. The error indicates the power board is overheating, and continuing to operate the appliance could cause permanent damage to the electronics or create a fire risk. Leave the oven off and allow it to cool completely before inspecting the ventilation and installation conditions.

Repair costs depend on which component is at fault. If the fix is simply clearing blocked vents or repositioning insulation, there may be no parts cost, only a service call fee typically in the range of $80 to $150. A replacement tangential fan can add $50 to $120 in parts, while a new power supply board can range from $150 to $350 or more depending on the specific model, plus labor.

Some causes of ER07 can be addressed without replacing parts. Start by checking that the oven has adequate clearance from surrounding cabinetry and that all ventilation openings are clear of debris. Confirm that the internal insulation panels are properly positioned. If the tangential fan or power board needs replacement, those repairs involve working inside the appliance and are best handled by a qualified technician.

Resetting the oven by cutting power at the circuit breaker may temporarily clear the error code once the board has cooled down. However, if the underlying cause such as blocked vents, a failed fan, or bad insulation has not been corrected, the ER07 error will return as soon as the oven heats up again. A reset alone does not fix the problem.
