Electrolux Oven Error Code PUOr

PUOr means that one or more user-configurable parameters stored in the oven's control board memory have been detected outside their acceptable range. This is a control system error rather than a heating or sensor fault. It most commonly results from a power disruption that corrupts stored settings. Resetting the oven's user parameters to factory defaults is the standard first step.

PUOr is a settings and memory integrity error, not a direct indication of a dangerous heating or electrical fault. However, because the control board's stored parameters are in an invalid state, the oven may not behave predictably, including temperature calibration that could be unreliable. It is advisable to resolve the error before using the oven for cooking to ensure it operates within expected parameters.

The most effective prevention is using a surge protector or whole-home surge protection device to shield the oven's control board from power spikes. Avoid unplugging or cutting power to the oven during active operation or while the control panel is saving settings. If power outages are frequent in your area, investing in a UPS or dedicated circuit protection can reduce the risk of memory corruption that leads to PUOr.

A factory reset of the user parameter settings will clear PUOr in many cases, particularly if the error was caused by a power surge or a setting that was manually entered incorrectly. If the error returns shortly after the reset, the control board's memory may be failing and a reset alone will not be a permanent fix. In that situation, the main control board would need to be replaced.

If the issue is resolved by resetting user parameters, there is no parts cost and only a service call fee if a technician is involved, which typically ranges from $75 to $150 depending on your region. If the main control board needs replacement, parts and labor combined generally range from $200 to $500 or more, depending on the specific board and local labor rates. Getting a diagnostic visit first can help confirm whether a board replacement is actually needed.
