Frigidaire Dryer Error Code EA3

EA3 means the dryer's control board has detected that the incoming AC line voltage is too low to operate safely. On a 240V system, the voltage must be at or above 180 Vrms, and on a 120V system, it must be at or above 90 Vrms. The code can also appear if the microprocessor has become corrupted or if the main control board itself has an internal fault. A technician will need to measure the supply voltage to determine the correct cause.

No, you should not continue running the dryer while EA3 is active. Operating the appliance with insufficient line voltage can stress the motor, heating element, and control components, potentially causing additional damage. Address the power supply issue or have the control board inspected before resuming use.

A reset may temporarily clear the EA3 code, and attempting a restart is a recommended first step after confirming or correcting the supply voltage. However, if the underlying problem is not resolved, such as a persistently low supply voltage or a faulty control board, the code will return. A reset alone is not a fix and should only be tried after the power supply has been verified to be within spec.

Some causes of EA3 are accessible to a knowledgeable DIYer. You can check your breaker panel for a tripped breaker leg, inspect the power cord connections at the terminal block, and test the outlet voltage with a multimeter. If the voltage checks out and the dryer still will not start, replacing the control board is the next step, which is a more involved repair that requires electrical comfort and proper safety precautions.

If the cause is a tripped breaker or a loose connection, there may be little to no cost involved. If the outlet or power cord needs replacement, parts and labor typically range from around $50 to $150. A main electronic control board replacement, including parts and professional labor, generally falls in the range of $150 to $350, depending on your location and the specific model.
