What 0xB2 means on a Electrolux dryer

Error code 0xB2 on an Electrolux dryer indicates that the control board has detected a power supply amplitude that exceeds the acceptable range for the appliance. Specifically, the line voltage coming into the dryer is reading higher than the product's rated specification. The main control board continuously monitors incoming AC voltage, and when that voltage climbs beyond the threshold the board is programmed to accept, it triggers this fault to protect internal components from damage caused by overvoltage conditions.

The most likely cause is an issue with the home's electrical supply rather than a faulty dryer component. Utility voltage fluctuations, problems at the breaker panel, or wiring issues in the wall outlet circuit can all result in elevated line voltage reaching the appliance. For electric dryers, the nominal supply is typically 240V in North America, and significant deviations above that threshold can trigger this code. A true voltage reading at the outlet using a multimeter is the essential first diagnostic step.

If the measured line voltage is within the product's specified range and the error persists, the main control board itself may be misreading the incoming voltage due to an internal component failure on the board's power monitoring circuit. In that scenario, the board is generating a false positive fault rather than responding to an actual overvoltage condition. Distinguishing between a genuine supply problem and a failed board requires confirming the actual outlet voltage before condemning any parts.

Common causes of 0xB2

  1. 01

    Elevated Line Voltage at the Wall Outlet

    Wiring / connection

    The utility supply or home wiring is delivering voltage above the dryer's rated specification. Measure the voltage at the dryer's outlet or terminal block with a multimeter to confirm whether the supply is out of range.

  2. 02

    Utility Voltage Fluctuation or Power Surge

    Wiring / connection

    Temporary spikes or sustained high voltage from the utility grid can trigger this fault. Check with your utility provider if neighbors are also experiencing voltage issues, and inspect for any recent surge events.

  3. 03

    Wiring or Breaker Panel Issue

    Wiring / connection

    A faulty neutral connection, miswired outlet, or problem at the breaker panel can cause one leg of a 240V circuit to read abnormally high. A licensed electrician should inspect the panel and outlet wiring if the multimeter confirms overvoltage.

  4. 04

    Faulty Main Control Board

    Part replacement

    If the line voltage measures correctly within specification but the error code persists, the main control board's voltage sensing circuit may have failed and is generating a false fault. Replacing the main board is the corrective action in this case.

Frequently asked questions about 0xB2

What does 0xB2 mean on a Electrolux dryer?
Error code 0xB2 means the dryer's control board has detected that the incoming line voltage is too high, outside the acceptable range for the appliance. The dryer shuts down to protect its internal components from overvoltage damage. The fault points either to an actual high-voltage condition at your home's electrical supply or to a failure of the main control board's voltage monitoring circuit.
How do I fix error code 0xB2 on my Electrolux dryer?
Start by measuring the actual voltage at the dryer's wall outlet or terminal block using a multimeter and compare it to the dryer's rated supply voltage. If the voltage is high, contact your utility provider or a licensed electrician to investigate the supply. If the voltage reads correctly and the error persists after restoring power, the main control board may need to be replaced.
Will resetting my Electrolux dryer clear the 0xB2 error code?
A reset may temporarily clear the code, but if the underlying cause is not resolved, the fault will return. If the line voltage is genuinely too high, the dryer will continue to detect the problem and re-trigger the error. The root cause, whether a supply voltage issue or a faulty control board, must be corrected for the error to stay cleared.
Is it safe to use my Electrolux dryer when the 0xB2 code is showing?
You should not attempt to bypass or ignore this error. An actual overvoltage condition can damage the dryer's electronics, create a fire hazard, or present a shock risk. Do not operate the dryer until the line voltage has been confirmed to be within the rated specification or the faulty component has been repaired.
How much does it cost to repair a 0xB2 error on an Electrolux dryer?
If the problem is a home wiring or supply issue, electrician fees typically range from $75 to $250 or more depending on the scope of the repair. If the main control board has failed and needs replacement, parts and labor for that repair generally range from $150 to $400 depending on the specific model and local labor rates.
