This post is about another case that reinforces my claim that “most repairs are easy” -especially when you know what to look for! One of my neighbours recently brought over a pressure cooker that had ceased to function. In quick initial tests, the unit powered up normally, and panel display and controls seemed functional, but the device heater did not come on.

This relay is of a common type used in many appliances and electronic thermostats to supply relatively high currents to resistive heaters.
