- Check the appliance identification plate and any wiring or service documentation to confirm the transformer listed for that model.
- Inspect the existing transformer and its connections before ordering, so any associated damage to wiring or connectors is identified at the same time.
- Have the appliance safely isolated from the electrical supply before any work on the transformer is carried out.
