Motor controllers and dimmers are commonly built around a simple circuit. Sometimes, this can fail, but may well be repairable.
Summary
Many household appliances such as vacuum cleaners and kitchen mixers and blenders have a continuously variable speed control using a triac. Older light dimmers use the same circuit though they work poorly with low energy CCFL and LED bulbs
Safety
- As with all mains-operated devices, an understanding of electrical safety is essential for any dissasembly or repair.
