Electrolux Dryer Error Code 0xB1

Error code 0xB1 means the dryer's control board has detected that the incoming power supply frequency is outside the acceptable configured range. The dryer monitors the AC line frequency continuously and will trigger this fault when it falls out of tolerance. The first step is to confirm the dryer is connected to a proper 208/240 VAC dedicated circuit supplying the correct frequency.

It is not recommended to continue operating the dryer while this code is active. The error indicates the control board has flagged an out-of-range power condition, and running the appliance under incorrect electrical conditions can cause damage to internal components. Have the power supply verified and the issue resolved before resuming use.

If the fix involves correcting the home's electrical circuit or outlet, costs can range from minimal to a few hundred dollars depending on the electrical work required. If the main control board needs replacement, parts and labor combined typically range from $150 to $400 or more depending on the model and local labor rates. Getting a professional diagnosis first can help avoid unnecessary parts replacement.

Start by verifying that the dryer's power supply meets the 208/240 VAC specification using a multimeter capable of measuring AC frequency. Check that the outlet or terminal block connections are secure and show no signs of damage or arcing. If the supply checks out correctly and the error persists, the main control board may have a faulty frequency sensing circuit and may need to be replaced by a qualified technician.

A reset may temporarily clear the error code, but if the underlying power supply issue has not been corrected, the fault will return once the dryer resumes monitoring the line frequency. Address the root cause at the electrical supply or wiring level first. If the control board is faulty, a reset will not permanently resolve the problem.
