How to Fix / Troubleshooting
Safety first: Immediately turn off power at the breaker and disconnect if you smell burning. Do not continue to operate the system.
- Visual inspection: After components cool, open access panels and look for discolored wires, melted insulation, or burnt components.
- Tighten connections: With power off, tighten all screw and lug connections on contactors, breakers, and terminal blocks.
- Do not ignore: Do not restore power if you see significant damage. Components like motors, contactors, or boards may need replacement.
Because of fire risk, have a Trane technician inspect and repair any overheating issues before using the system again.
