Electrolux Dryer Error Code B2

The B2 code means the dryer's control board has detected that incoming power supply voltage is too high, outside the acceptable operating range. The dryer shuts down to protect its components from damage caused by excessive voltage. The issue can originate from the home's electrical supply or from a fault within the main control board itself.

No, you should not continue running the dryer while B2 is active. If the home's supply voltage is genuinely elevated, operating the dryer could damage the heating element, motor, and control electronics. Stop using the appliance until the voltage supply has been confirmed as normal or the faulty control board has been replaced.

Resetting the dryer by unplugging it for a few minutes may temporarily clear the B2 code, but the error will return if the underlying cause has not been addressed. If high voltage is present at the outlet, the board will detect it again and re-trigger the fault. A lasting fix requires either correcting the power supply issue or replacing the main control board if it is generating a false fault reading.

Some causes of B2 are addressable without professional help, such as verifying and tightening connections at the dryer's terminal block. However, diagnosing actual voltage levels at the outlet requires a multimeter, and any wiring issues found inside the electrical panel or home wiring should be handled by a licensed electrician. If the main control board needs replacement, a technician familiar with appliance electronics is recommended.

If the cause is a genuine high voltage condition from the home's wiring, electrician fees to diagnose and correct wiring issues typically range from $75 to $250 or more depending on the scope of work. If the main control board is the faulty component, board replacement parts and labor costs generally range from $150 to $400 depending on the specific model and service rates in your area.
