How to Fix / Troubleshooting
Safety: Ensure the outlet is not live before handling the plug; always unplug before opening panels.
Steps:
- Check external power: Test the wall outlet with another appliance. Reset any tripped breakers or GFCI outlets.
- Inspect power cord: Look for visible damage along the Transtherm power cord. Replace the power cord if damaged.
- Access control board: Remove the control cover and locate the small fuse on the main PCB. Test it with a multimeter and replace with the same rating if blown.
- Evaluate board: If the fuse blows again immediately or there is no low-voltage output, the main control board is likely faulty and should be replaced.
Warning: Never bypass or upsize the fuse; this can cause fire or further damage.
