How to Fix / Troubleshooting

Safety first: Disconnect power before accessing heater wiring. Heater components can be hot.

Access evaporator heater: Remove the front panel and inner cover to locate the Adler harvest heater attached to or behind the evaporator plate.
Test heater element: Disconnect the heater leads and measure resistance with a multimeter. An open circuit indicates a failed heater.
Check thermal fuse and thermostat: Locate any inline thermal fuse or harvest thermostat in series with the heater and test for continuity.
Inspect wiring: Look for burnt connectors or damaged insulation along the heater circuit.
Replace defective parts: Install a new Adler harvest heater assembly or thermostat as required, following the original routing and securing of wires.
Run harvest test: Restore power and initiate a manual harvest (if supported by your Adler model) to confirm proper ice release and that E09 clears.

Display shows E09; ice forms but does not harvest properly, often sticking to the evaporator.
