Frigidaire Dryer Error Code E5C

E5C means the dryer's control board has detected a voltage level that is too high from the incoming power supply. The board monitors line voltage continuously and triggers this code when it exceeds the safe operating range. This is typically a power supply issue rather than a problem with the dryer itself. The first step is to have the utility company check the voltage and frequency of the power being delivered to your home.

You should not continue operating the dryer while E5C is active. An over-voltage condition can damage the control board, motor, and other internal components over time. The dryer may also pose a fire or shock hazard if the elevated voltage is caused by a wiring fault. Leave the dryer unplugged until the source of the problem has been identified and corrected.

Cost depends entirely on what is causing the over-voltage condition. If the utility company corrects a supply issue on their end, there may be no cost to you. Electrician labor to inspect or replace a breaker or outlet wiring typically ranges from $100 to $300 or more depending on the repair scope. If the dryer's control board has been damaged by the over-voltage event and requires replacement, that part alone can range from $150 to $400, plus labor.

Some steps are DIY-friendly, such as visually inspecting the power cord, outlet, and dryer terminal block for obvious damage. However, testing incoming line voltage with a multimeter and diagnosing circuit breaker or utility supply issues involves working with high-voltage electricity, which carries serious safety risks. It is best to contact your utility company first and then a licensed electrician if the issue is in your home's wiring.

Resetting the dryer by unplugging it and restoring power may temporarily clear the E5C code, but the error will return if the underlying voltage problem has not been fixed. A reset does not address the root cause. The code will continue to appear until the incoming power supply is confirmed to be within the correct voltage and frequency range.
