Display shows "Hi" for temperature; unit may run continuously.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Open cabinet sensor circuit, Disconnected sensor plug, Broken sensor lead, Faulty main PCB input

Safety: Disconnect power before accessing interior panels.

Steps:

Inspect sensor connection: Remove the interior rear panel and locate the cabinet sensor. Ensure its connector is fully seated.
Test sensor: Measure resistance at room temperature. Infinite resistance indicates an open sensor. Replace with a Fagor-compatible NTC sensor.
Check harness continuity: Test from sensor to main PCB. Repair any open wires.
Replace main PCB: If wiring and sensor are good but "Hi" remains, the control board is likely faulty.
