BURNER IGNITOR
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 2200°F in about 30 seconds.
Gas contacting the ignitor at this temperature
will ignite immediately.
Unplug dryer of disconnect power.
Turn off gas supply to dryer.
Remove the gas burner ignitor
(See page 4-40).
Disconnect the ignitor wire connectors from
the main harness connector.
Set ohmmeter to the R X 1 scale.
Set digital ohmmeter to lowest scale.
Touch the ohmmeter test leads to the 2-
wire connector pins. The meter should
indicate between 50 and 250 Ω at room
temperature.

MANOMETERS
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 dryers operating off of
a small supply line, or an improperly converted
dryer 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.
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.
