Possible Causes

Open or shorted thermistor, loose sensor connector, damaged wiring harness, failed main control board sensor circuit

How to Fix / Troubleshooting

Safety: Unplug the unit before opening the cabinet.

Steps:

  • 1. Identify sensor type: Consult the service manual or wiring diagram (often behind the front grille) to determine which sensor ES refers to on your specific Frigidaire model.
  • 2. Locate sensor: Find the indicated thermistor (room, evaporator, or condenser) and inspect its mounting and wiring.
  • 3. Test resistance: Disconnect and measure resistance at room temperature. Compare to spec. Replace if defective.
  • 4. Check board: If all sensors test good, the main control board may have a failed input and require replacement.
