DEFINITIONS
The amount or the rate of flow of electrical current.
A coil used to assist the holding coil to raise the plunger in the gas valve allowing gas to
into the second chamber of the valve.
British Thermal Unit is the quantity of heat required to raise the temperature of one pound of
o
water 1 F.
A switch device in a motor used to change the path of electricity from both start and run
winding to run winding only. It also completes the circuit to the heat source when motor
reaches speed.
Air movement measured in cubic feet per minute.
Devices attached to the inside of the tumbler used to lift and tumble the clothes during
operation of the dryer.
A device which accepts and registers the number and denomination of coins used to start
dryer.
A construction of aluminum or galvanized steel pipe used to convey moisture laden air from
the dryer to the outside.
The process of expelling moisture from garments by heat and/or air movement.
A damper placed at the terminating end of the ducting which prevents air from entering the
duct when the dryer is not running.
A stationary bearing surface at the front on which the dryer tumbler turns.
A coil used to open the first valve in the gas valve assembly. It holds the valve open after
the initial assistance from the booster coil.
A silicon carbide igniter located on the burner bracket near the main orifice. It can reach a
temperature of 2200 o F. in 30 seconds to ignite the gas (when allowed to flow through gas
valve orifice).
A solid state indicator unit found as a single light and in a display Diode arrangement to
numbers and letters.
An instrument for measuring the pressure of gas or air.
The "brains" of the control board. A solid state "count and switch" processor device.
A unit of measurement of resistance (opposition to the flow of current).
A circuit in which there is more than one current path.
Thermostat-like device which reacts to the brightness or radiant energy output of a heat
source.
A coil operated switch used to control dryer motors, heating element or gas valve on
computer models.
A coil operated switch used to control dryer motors, heating element or gas valve on
Computer models.
A device used to limit the flow of current or reduce voltage.
The main electromagnetic winding in a motor.
A circuit in which there is only one current path through all components.
(Phase winding) An auxiliary winding used in an A.C. motor to assist the main winding in
developing starting torque.
A bimetal switch which reacts to temperature changes.
Cylinder which contains and tumbles clothes.
Wattage is a unit of measurement of the capability of electricity to do work.
