Electrolux Dryer Error Code EH2

EH2 indicates that the dryer's control board has detected a power supply voltage that is too high, outside the acceptable operating range. This fault is designed to protect the appliance from damage caused by overvoltage conditions. The cause can be actual high voltage at the outlet, an incorrect MCF setting on the control board, or a failing main control board.

It is not recommended to continue operating the dryer while EH2 is active. The fault indicates a potentially damaging overvoltage condition, and running the appliance under those circumstances could harm the control board, motor, or other electronic components. Address the voltage issue before resuming use.

Repair costs vary depending on the root cause. If the issue is a wiring correction or MCF reconfiguration, costs may be minimal, primarily covering a service call in the range of $75 to $150. If the main control board needs replacement, parts and labor combined can range from $200 to $450 depending on the specific model and labor rates in your area. An electrician may also be needed if the overvoltage originates from the home's electrical system.

Start by measuring the actual voltage at the dryer's wall outlet or terminal block using a multimeter to confirm whether an overvoltage condition is present. If the voltage is within the correct range, verify that the MCF configuration on the control board is set correctly for your dryer's rated voltage. If both checks pass without finding a problem, the main control board may need to be replaced.

A reset may temporarily clear the EH2 fault, but if the underlying cause, such as high supply voltage or an incorrect MCF setting, has not been corrected, the error will return. Resetting without diagnosing and fixing the root cause is not a permanent solution and may allow repeated exposure to damaging voltage levels.
