How do I Fix an Oster Steam Iron?

A broken steam iron does not necessarily mean you need to buy a replacement. Most steam irons are relatively uncomplicated, and often the problem can be resolved with part replacement or even a thorough cleaning. Oster irons in particular feature a temperature indicator for safe storage, a non-stick soleplate and a variety of settings. Some also offer a self-cleaning option, though if you've been having trouble with your iron you should try cleaning by hand. If the problem is internal or electric, you should either consult a professional or replace your iron; it may be less costly than rewiring internally.

  1. 1

    Unplug the iron and make sure it is cooled. Some Oster irons have indicator lights letting you know when it is safe to handle or store the iron.

  2. 2

    Give the iron a deep cleaning. Iron cleaning gel is available to remove built-up grime from the soleplate. Apply the cleaning gel and use a sponge or steel wool to scrub the soleplate, allowing the iron to cool again and use a toothpick to remove any residue from the steam vents. For the steam valve you may need a needle to pick out mineral deposits.

  3. 3

    Flush the water tank. Undistilled water can eventually damage the iron. Use equal parts vinegar and warm water to clean the tank by steaming over the sink or a strainer, then use filtered water in the future and drain between uses.

  4. 4

    If your iron is still heating erratically, it may be a problem with the electrical cord or thermostat. Check several outlets and adjust the thermostat to determine the problem. Replacement cords and thermostats are available, ranging from $20 to $50 dollars depending on model. Contact Oster about replacement parts to decide whether it is more cost effective in your case to repair or replace.
