The E71 error on your Frigidaire dryer means the control board has detected a communication failure between the main control board and the user interface (touchpad/display) board. The dryer will usually stop mid-cycle and refuse to start again until the fault is cleared. Checking the wiring connections between the two boards is the best place to start.

Error code E71
Meaning Communication error between the main control board and the user interface board
Severity Medium — dryer won’t run until fixed, but no safety hazard
Time to fix 15–45 minutes
Tools needed Phillips screwdriver, nut driver, multimeter (optional)

What the E71 error means

Frigidaire dryers use two separate boards: a main control board that runs the cycle and a user interface board behind the touchpad and display. These two boards talk to each other through a ribbon cable or wiring harness. The E71 code appears when that communication link drops out, usually because of a loose connector, a damaged cable, or a fault on one of the boards themselves.

This is one of the more common dryer fault codes and, in most cases, it is caused by something mechanical (a loose plug) rather than a fully failed board.

Common causes

  • Loose or partially disconnected ribbon cable between the control board and user interface
  • Corroded, bent, or dirty pins on the connector
  • A damaged or pinched wiring harness behind the control panel
  • Moisture or humidity affecting the control board contacts
  • A failed user interface (touchpad/display) board
  • A failed main control board

How to fix the E71 error

  1. Power cycle the dryer. Unplug it or switch off the breaker for 5 minutes, then reconnect. This clears many temporary communication faults.
  2. Open the control panel. Remove the screws holding the top control panel in place and gently tilt it forward to expose the wiring.
  3. Check the ribbon cable and connectors. Locate the cable or wire harness linking the main board to the user interface board. Unplug and firmly reseat each connector, making sure it clicks fully into place.
  4. Inspect for damage. Look for frayed wires, bent pins, or scorch marks on either board. Straighten bent pins carefully with tweezers if needed.
  5. Test with a multimeter. If you’re comfortable doing so, check continuity across the ribbon cable to rule out an internal break.
  6. Replace the faulty board. If reseating connections doesn’t clear the code, the user interface board is the more common failure point and should be replaced first. If the error persists, replace the main control board.

FAQ

Can I still use my dryer with an E71 error showing?
Usually not — the dryer typically won’t start or will stop mid-cycle until the communication fault is cleared.

Does the E71 code always mean I need a new board?
No. Most E71 errors are caused by a loose or dirty connector rather than a failed board. Reseating the connections fixes it in many cases.

How much does it cost to fix an E71 error?
If it’s just a loose connection, it costs nothing but your time. A replacement user interface board typically runs $80–$180, plus labor if you hire a technician.

If you’re dealing with error codes across other Frigidaire appliances, it’s worth checking guides like the Frigidaire EF Error Code: Causes and Fixes, Frigidaire CA Error Code: Causes and Fixes, or the Frigidaire CE Error Code: Causes and Fixes for similar board and sensor communication issues. Frigidaire refrigerators can also throw related faults covered in the Frigidaire EC Error Code: Causes and Fixes, and if you have a Maytag washer in the laundry room too, the Maytag Washer E1 Error Code: Causes and Fixes guide covers a comparable communication error on that machine.
