Possible Causes

Failed ambient thermistor, Sensor dislodged from correct location, Wiring damage near top or rear of cabinet

How to Fix / Troubleshooting

Safety first: Disconnect mains power before removing any covers.

Step 1 – Locate ambient sensor:

On many Brandt models, the ambient sensor is located behind the top front trim or near the condenser area.
Remove the top cover or control housing screws to access it.

Step 2 – Inspect and test:

Check that the sensor is not touching hot components (like the condenser) and is properly positioned to sense room air.
Disconnect the sensor and measure resistance with a multimeter; compare to expected values for room temperature.
Replace if open, shorted, or clearly out of range.

Step 3 – Refit and test:

Install the new sensor in the same location, away from heat sources.
Reconnect wiring, reassemble covers, and restore power.
Verify that E7 clears and that the unit cycles normally.
