How to Fix / Troubleshooting
Safety first: Unplug the unit before inspecting wiring.
- Step 1 – Inspect main sensor harness: Locate the multi-wire harness that connects various sensors (temperature, level, bin) to the main control PCB on your Teendow ice maker.
- Step 2 – Reseat connectors: Disconnect and reconnect each sensor plug one at a time, ensuring a firm fit.
- Step 3 – Look for damage: Check for pinched, rubbed, or chewed wires along the harness route. Repair any damaged sections with proper connectors and insulation.
- Step 4 – Test individual sensors: If available, follow the service manual to test each sensor’s resistance or function. Replace any that are out of specification.
- Step 5 – Replace control board: If all sensors and wiring test good, the main control PCB may have a failed sensor input and should be replaced.
