A bimetal switch used to open the electric circuit to the defrost heater once a set temperature is reached. The defrost cycle will continue until the timer advances into the cooling cycle, however the heater will no longer be energized. This thermostat will reset to a closed position once a set colder temperature is again reached.
An electro-mechanical clock device that periodically switches from cooling to defrost to remove the buildup of frost from the evaporator.
An appliance designed to extract moisture from the ambient air by means of a refrigeration system. Warm moist air is drawn by a fan across the cold evaporator which causes the water vapor to condense onto the coil and drop into a container. The cooled air is then passed over the condenser where it is warmed before being passed back into the surrounding area.

A pan-shaped panel used to collect condensate from the evaporator during a defrost cycle. It is usually located above a condenser coil or atop the compressor.

A term used to describe any device that turns electrical power into mechanical work or vice versa.
Refrigerator- A switch that when activated opens a circuit to an electric cabinet perimeter heater, to turn it off, to save electricity Air Conditioner- A switch that when activated allows the thermostat to cycle the fan motor on and off at the same time as it cycles the compressor.
That part of the refrigeration system in which the refrigerant evaporates, absorbing heat from the surrounding area.
A male connector that attachers to a water faucet allowing a female connector, (such as a dishwasher uni-couple) to attach to it.
An electro-mechanical device that opens a valve to allow water to flow. The electric current causes a magnetic field to develop in the solenoid coil which in turn then moves a metallic plunger. The plunger is attached to a diaphragm which opens the valve.
A device containing screen and absorbent material through which refrigerant gas is passed in order to remove moisture that would be detrimental to other components and the functioning of a refrigeration system.
A device containing a porous material or a material itself, through which a liquid or gas is passed in order to separate suspended particulate matter. Common filter materials are activated charcoal, polypropylene and HEPA (high efficiency particulate air [filter]).
Trade name for a family of synthetic chemical refrigerants manufactured by DuPont.
A type of appliance that automatically defrosts by means of a timing device.
An abbreviation for Factory Specification Parts. Used by Whirlpool to differentiate genuine factory replacement parts from those of After Market or universal replacement parts.
A resilient or flexible material used between mating surfaces to provide a leak-proof seal.
An unpowered pulley used to put tension on the belt of a dryer or washing machine.
A solid state semiconductor, usually made of Carborundum that produces heat when a current is applied. Typically used to ignite natural gas or propane in heating appliances, such as ranges, dryers and water heaters.
A switch that controls the amount of heat generated by an electric range surface burner. It accomplishes this by quickly cycling the voltage on and off to achieve an intermediate range (e.g. at medium it may supply 100% voltage for only 50% of the time it is switched on). It does not act like a rheostat and reduce the voltage, to lessen the heat generated.
The heat energy absorbed in the process of changing the sate of a substance (e.g. from solid to liquid to gas, or vice versa) without changing the temperature or pressure.
A bimetal switch used to open the electric circuit once a set temperature is reached. This thermostat will usually reset to a closed position once a set colder temperature is again reached.
A type of refrigerator that does not have a mechanical defrosting system and must be defrosted manually. This type of appliance usually has one main outer door with a small door inside, covering the evaporator box.
An appliance that uses microwaves (radio waves in the microwave spectrum) to create friction at the molecular level, to generate heat in food.
A piece of plastic used to cover the joint between the inner and outer cabinet of a refrigerator or freezer.
An electric heater mounted inside the mullion to prevent moisture from forming in humid weather.
The stationary part of a structure between two doors.
An abbreviation for Original Equipment Manufacturer. Usually used to differentiate replacement parts supplied by the appliance manufacturer and those of after market or universal replacement parts (e.g. FSP® is used to denote genuine Whirlpool OEM replacement parts).
An electric switch that senses temperature or current (amperage) to stop operation of a unit if a dangerous condition arises.
An electric switch activated by air pressure. This device detects air pressure exerted on it through a flexible tube connecting it to part of a water tub. When activated, this switch then opens an electrical circuit stopping further filling of the machine. May also be called a Water Pressure Switch or Water Level Control.
A machine or device used for moving or compressing fluids or gases.
R12 (dichlorodifluoromethane) - is typically used in household refrigerators, freezers and older car air conditioners. R22 (monochlorodifluaromethane) - is used in window air conditioners. R134a (tetrafluoroethane) - is now used in many domestic refrigerators, freezers, dehumidifiers and car air conditioners.
A substance used in a refrigeration system to absorb heat in the evaporator coil, by means of a change of state from liquid to a gas, an to release its heat in the condenser as the substance returns from the gaseous state back into a liquid.
An appliance designed to transfer heat from the interior of the cabinet to the exterior.
An electro-mechanical switch that diverts the current when the flow is changed or when an external current is applied.
A silver-alloy solder containing 5-15% silver. Is is used to weld copper to copper joints in refrigeration systems and is able to withstand high pressures.

An electro-mechanical device that produces a magnetic field, to move an internal metallic plunger, when power is supplied. When power to the electromagnet is discontinued, the plunger is free again to move by other forces. This plunger can be attached to other devices (levers, seals, etc.) to do mechanical work.
A male connector that attaches to a water faucet to allow a female connector (dishwasher unicouple) to attach to it. This device sometimes includes an aerator and is more properly called a dishwasher Faucet Adaptor.
