Presto Heat Dish Problems

The Presto Heat Dish is a small electric space heater that heats a small area. It can fail for a variety of reasons. 

A blown fuse or circuit breaker is the most common cause of a malfunction. The heater will not turn on if the Presto Heat Dish is plugged into an outlet and the fuse or breaker is tripped.
