What to check in your Maytag gas
dryer when is not heating.
Warning: Please check with your city or state to see
if you need any permit or license to work on your
gas dryer before doing any repairs. Never disconnect
any gas pipes on your gas dryer, the repairs that we
show you how to do, don't require doing so.
The igniter is the part that ignites the gas in the
Maytag gas dryer. Long time a go the dryers use to
have a pilots. The pilots where on all the time,
even when the dryer was not been use.
This wasted a lot of gas and a new design was
needed. That is when the igniter or glow bar as is
also known, came to be. A bad igniter could be the
reason for your Maytag gas dryer not heating.
The radiant sensor is a small black box that
attaches to the combustion funnel. The job of the
radiant sensor is to allow the igniter to glow until
it is real hot, then it shuts the igniter off and
opens the gas valve to start the heating process. A
bad radiant sensor could the the reason for your
Maytag gas dryer not heating.
The gas valve has two coils or solenoids. These
coils job is to open the gas chambers inside of the
gas valve.
When one of the coils goes bad, the symptom is that
the igniter glows, but the gas valve won't open to
let the gas flow through the gas chamber to be
ignited.
A bad set of coils could be the reason for your
Maytag gas dryer not heating.
The hi-limit thermostat is located on top of the
combustion funnel, and its job is to open the
circuit to the gas valve if the airflow to the dryer
is restricted for any reason.
The cycling thermostat is use to control the
temperature inside of the dryer. It is factory
preset at 155 degree, in other words it will open
the circuit to the gas valve when the temperature
reaches 155 degrees.
This thermostat is opening and closing all the time
the dryer running. A bad cycling thermostat could be
the reason for your Maytag gas dryer not heating.
The timer is the part that direct the electricity to
the other parts in the dryer. This part works very
hard and the contacts wear out and some times they
burn out. If the timer contacts won't close, the
dryer will not heat.
The motor switch is another safety device that only
closes the heating circuit when the motor is
running. When the motor is not running the circuit
of the gas valve is open and the dryer will not
heat. A bad motor switch could be the cause for your
Maytag gas dryer not heating.
As you could see, there are a lot of parts inside of
the dryer that have to be in good working condition
for the dryer to produce heat.
