How Do I Get A Long Life From A Transformer?

January 29, 2006

A quality transformer, when treated properly, should have a lifespan of 30+ years. (Pictured: Lionel CW-80 80-Watt Transformer)

The golden rule is to ALWAYS operate the transformer within its rating. It is also important to keep the transformer dry and avoid damp areas (take particular care in basement locations).

When not using your train layout unplug the transformer. Don’t walk away and leave it plugged in and unattended as it could start a fire. If a transformer gives off a burning odor, or expels smoke, heed these warning signs and immediately replace it or take it in for servicing.

A loud BUZZING noise coming from a transformer could be due to the transformer’s core laminations moving. Servicing would be needed as this vibration can cause damage to insulation in contact with the moving metal.

A transformer’s circuit breaker can trip occasionally. If this happens simply unplug the transformer and let it cool off. The transformer will usually work again after it has cooled down. However, if the transformer continues to trip without a load, it will need servicing to fix the problem.

One more thing; NEVER use a transformer with a damaged, split, or cracked power cord. If in doubt have the transformer serviced immediately.
