Electrolux Dryer Error Code H2

The H2 code means the dryer's control board has detected that the incoming power supply voltage is too high, exceeding the acceptable amplitude range. The dryer shuts down automatically to protect its internal components. The fault points either to a genuine high-voltage condition at the electrical supply or to a failed control board that is misreading the voltage.

No, you should not continue operating the dryer while the H2 code is active. Sustained high voltage can damage the control board, motor, and other electronic components. If the voltage at your outlet is genuinely too high, it also poses a risk to other appliances and electronics in your home. Stop using the dryer and investigate the power supply before restarting it.

Repair costs vary depending on the root cause. If the problem is a utility or wiring issue, an electrician's service call to diagnose and correct the wiring typically runs in the range of $75 to $250 or more depending on the complexity. If the main control board has failed and requires replacement, parts and labor combined can range from $150 to $400 or higher depending on the specific board and local labor rates.

Some steps are DIY-friendly, such as measuring the outlet voltage with a multimeter to check whether the supply voltage is actually out of range. However, any work involving the electrical panel, outlet wiring, or neutral connections should be handled by a licensed electrician. If the supply voltage is normal and the main control board needs replacement, a technician familiar with Electrolux dryers is recommended for that repair.

A reset may temporarily clear the code, but if the underlying cause is not corrected, the H2 fault will return. If the supply voltage remains too high, the control board will detect it again and re-trigger the error. A reset is only useful as a step after you have confirmed and corrected the root cause, such as after resolving a wiring issue or replacing a faulty control board.
