Maytag Gas Dryer doesn't heat up
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.
