Orifice
– A small hole of a specific calibrated size to provide proper BTU
output to a particular burner in a gas appliance.
Out
of balance trip
– Not a Spring Break drive to Florida, but a washer mechanism that’s
designed to be ‘tripped’ when a machine’s load goes out of
balance.
Oven
sensor
– Used in electronically controlled ovens, this little probe contains
a thermistor. This is a solid state device whose electrical resistance
varies with temperature. Its resistance is measured by the
microprocessor, which then cycles the oven heat on or off as necessary
to maintain the selected temperature.
Overload
protector
- A device that
protects against, well, overloads <grin>, that usually provides
both overheating and over-current protection, opening a circuit whenever
either happens. Most motors and refrigeration compressors have
these.
