Frigidaire Dryer E5C error code

The control board detected voltage above what it can safely handle. This is a power supply problem or a failing main control board.

Also shown as: E5C, 5C

Last updated: October 6, 2026

Quick answer: Frigidaire dryer error code E5C: voltage too high. The most common cause is voltage spike or surge from the power grid. Try this first — power-reset the dryer. If that does not clear it, look for wider power problems. If the code persists, call a qualified technician.

What causes the E5C error?

  • Voltage spike or surge from the power grid
  • Dryer wired to the wrong voltage
  • Loose neutral connection in the house wiring
  • Failing main electronic control board
  • Storm or utility work disturbing the power supply

How to fix Frigidaire E5C — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Power-reset the dryer
    Unplug the dryer or switch off its breaker for 10 minutes, then restore power. If a brief surge caused the code, the reset clears it. Run a short cycle and watch whether E5C comes back.
  2. Look for wider power problems
    Check whether lights flicker or other appliances act strangely. If the whole house is affected, the problem is your electrical supply, not the dryer. Note when it happens and tell your power company or an electrician.
    Safety warning: Do not probe the dryer outlet with a meter yourself. Dryer outlets carry 240 volts.
  3. Use a surge protector going forward
    Once the code is cleared, consider a whole-home or heavy-duty surge protector for the laundry circuit. Repeated surges shorten the life of electronic control boards.
  4. Call a technician if the code returns
    A returning E5C with normal house power points to the main control board. Board diagnosis and replacement involve live-voltage testing and are technician work.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • E5C returns after a power reset with normal house power
  • Lights flicker or breakers trip elsewhere in the house (call an electrician first)
  • The dryer was recently moved or rewired
  • You smell hot plastic or see scorch marks near the control panel

Frequently asked questions

Can a thunderstorm cause E5C?

Yes. Lightning and grid switching cause voltage spikes, and the dryer logs E5C when the spike exceeds what the board tolerates.

Is it safe to keep using the dryer with E5C?

Reset it once and try a cycle. If the code returns, stop using the dryer until the cause is found. Running on bad power can destroy the control board.

E5C vs E5B: what is the difference?

E5C is about incoming voltage being too high. E5B means the dryer tried to heat and the temperature never rose. Different problems, different fixes.
