How to Fix / Troubleshooting
Safety: Work carefully around electrical outlets. Do not open the transformer casing.
- Check outlet power: Plug a lamp into the same outlet to verify power. Reset any tripped GFCI or breaker.
- Inspect transformer: Ensure the transformer is firmly plugged into the outlet and the low-voltage plug is connected to the control board.
- Test transformer output: If you have a multimeter and are qualified to use it, measure the low-voltage output. Replace the transformer if there is no output.
- Check control fuse (if equipped): Some models have an internal fuse on the control board. Replace only with the same type and rating.
- If still dead: The control board is likely defective and should be replaced.
