Electrolux Range Error Code 1,2,3,4

These codes all indicate a Runaway Temperature fault, meaning the oven detected that its internal temperature exceeded safe operating limits. The control system triggers this fault to shut down heating and prevent damage or a fire hazard. The most common cause is a faulty oven temperature probe, followed by a defective electronic control board.

No, you should not use the oven while a runaway temperature fault is active. This code indicates the oven may not be able to regulate its temperature properly, which poses a risk of overheating, food burning, or a potential fire hazard. The fault should be diagnosed and repaired before resuming use.

Resetting the range by cycling power at the breaker may temporarily clear the fault code, but it will return if the underlying cause has not been fixed. A failed temperature probe or defective control board will continue to trigger the fault during oven operation. A reset alone is not a repair and should only be used as part of the diagnostic process.

A knowledgeable DIYer can start by testing the oven temperature probe with a multimeter. If the resistance reads between 1050 and 1100 ohms at room temperature, the probe is functioning correctly and the electronic control board likely needs replacement. Probe replacement is a straightforward repair, but control board replacement requires careful handling of wiring connections and is best suited to someone comfortable with appliance electronics.

If only the oven temperature probe needs replacement, parts typically cost between $20 and $60 depending on the model, plus labor if you hire a technician. If the electronic control board is the cause, parts can range from $150 to $350 or more, making professional labor costs a significant additional factor. Getting a diagnosis first helps avoid replacing unnecessary components.
