Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
When the dryer control calls for heat, line
voltage is applied to the ignitor. The ignitor
will heat up quickly and glow as it reaches
approximately 1200°C (2200°F) in about 30
seconds. Gas contacting the ignitor at this
temperature will ignite immediately.
Unplug dryer or disconnect power.
Turn off gas supply to dryer.
Remove gas burner ignitor
(See page 4-39).
Disconnect ignitor wire connectors from the
main harness connector.
Set the ohmmeter to the R X 1 scale.
Set digital ohmmeter to lowest scale.
Touch ohmmeter test leads to the 2-wire
connector pins. The meter should indicate
between 50 and 250Ω at room temperature.

Insufcient gas ow can cause problems.
Therefore, checking the gas pressure at the
time service calls are performed may avoid a
return call.
Gas pressure can be checked with an
instrument called a “manometer.” This device
can detect a “low” LP tank, restricted gas ow,
bad gas valve, a malfunctioning pressure
regulator, too many gas appliances operating
off of a small supply line, or an improperly
converted appliance from Natural to LP gas.
Other types of manometers exist; however,
the type of manometer we will discuss in
this manual is a water tube with a glass
tube inserted into it. Water is added to the
outer tube and it rises within the inner tube
to equalize and seek its own level, the same
method is used in both arms of a “U” shaped
tube Manometer.
A exible rubber hose is connected to the
upper, open end of the manometer and to the
gas source. Gas pressure is exerted on one
of the water columns, pushing it down. The
water level then rises in the other column.
The pressure is then read on the manometer
as the water column pushes downward.
The water column (W.C.) for a Maytag dryer is
3.5” W.C. for Natural gas and 11” W.C. for LP
gas.
