Possible Causes

Open mullion heater element, Broken wire in door hinge area, Failed control board heater relay, Incorrect energy saver setting

How to Fix / Troubleshooting

Safety first: Disconnect power before accessing hinge covers or wiring.

Steps to resolve:

  • Check energy saver setting: Some KitchenAid models allow turning door heaters off. If you see condensation on door edges, turn the energy saver OFF to enable heaters.
  • Inspect door gasket and alignment: Poor sealing can mimic heater failure. Adjust doors and clean gaskets.
  • Inspect hinge wiring: Remove the top hinge cover and look for pinched or broken heater wires.

If E14 persists and condensation remains despite correct settings and good seals, the mullion heater or control board may be faulty. Replacement typically requires door disassembly and should be done by a technician.
