Kenmore Dryer Error Code EA3

EA3 means the dryer's electronic control board has detected that the incoming line voltage is too low. The dryer requires a proper 240-volt supply to operate, and if that voltage drops below the acceptable range, the control board triggers this fault code. The cause can be a household electrical issue such as a weak breaker or poor wiring connection, or in some cases, a faulty control board that is misreading the voltage.

You should not continue operating the dryer while the EA3 code is active. Low voltage conditions can cause the motor and heating components to draw higher-than-normal current, which can lead to overheating or component damage over time. Address the voltage issue or control board fault before resuming normal use.

Repair costs vary depending on the root cause. If the fix involves resetting or replacing a circuit breaker, costs are typically in the range of $5 to $50 for parts. Replacing a wall receptacle generally runs $10 to $30 in parts plus labor if a technician is used. If the electronic control board is the source of the fault, the board itself can range from $80 to $200 or more depending on the model, with additional labor costs if you use a professional repair service.

Start by measuring the voltage at the wall outlet using a multimeter to confirm the supply is providing the correct 240 volts. If the voltage is low, check for a tripped breaker, a failing breaker, or a loose connection at the outlet or dryer terminal block. If the line voltage is correct and the error persists, the electronic control board is likely faulty and will need to be replaced.

A reset may temporarily clear the EA3 code, but it will return if the underlying cause has not been corrected. If the line voltage is genuinely low or a connection is loose, the control board will detect the problem again during the next cycle. Resolve the electrical supply issue or replace the control board before relying on a reset.
