Possible Causes
Control locked at maximum setpoint, Miscalibrated cabinet sensor, Faulty main control board
How to Fix / Troubleshooting
Safety first: Basic checks can be done without opening the unit. Disconnect power before any internal inspection.
Steps to resolve HI indication:
- 1. Confirm function: Some Brandt models use HI to indicate the highest settable temperature. Verify in the user manual.
- 2. Adjust setpoint: Try lowering the set temperature. If the display remains stuck on HI, perform a power reset.
- 3. Verify actual temperature: Use a separate thermometer inside the cabinet. If the actual temperature is normal but the display shows HI, suspect a sensor or control issue.
- 4. Test and replace sensor: Follow the E1 procedure to test the cabinet NTC sensor. Replace if defective.
- 5. Replace main PCB if needed: If the sensor is correct and wiring is intact, a faulty main control board may be causing the HI indication and should be replaced.
