If the igniter works either a valve for gas or the thermocouple are suspect here.

SOURCE: dryer wont heat

About all that is left to replace is the flame sensor mounted at 9o'clock on burner flame tube, but I would double check your airflow, This is CRUCIAL to the normal operation of the dryer.
Also, a lint filter with an invisible coating from fabric sheets can cause an airflow disruption, try running without clothes and the filter removed.
Tip: Always provide the complete information provided on the manufacturers product information data tag, located on the unit, and not in the user’s manual. This will help you acquire a more accurate and expeditious response to your complaint.

The machine will check all safety features first. check the overlimit by the burner. It may have a reset. If not, turn power off and check continuity (ohms). Good luck.

Replace the 2 burner coils ,if the igniter keeps cycling trying to start the flame. If it doesn't replace the flame sensor mounted on the side of the burner tube.

A very common problem in a non-heating gas dryer is what is called the gas coils, especially if it will light briefly and then go out and not relight. You should also check the igniter and make sure there are not cracks or burned places, also thermal fuse and thermostat could cause a no-heat.

Maytag gas dryer runs but does not heat


If yo smelled gas then the ignitor may not be working.
First thing to check is the ignitor underneath the drum. (You have to open the panel to see it)  It should glow shortly after the dryer starts, then the flame starts and the ignitor shuts off.  If the ignitor does not glow then the thermostat is bad.  If the ignitor is glowing but the gas does not light then the gas valve coils may have to be replaced.   If the gas ignites but does not stay on either the flame sensor or the coils are at fault.

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.

Igniter works fine but there is no flame so therefore no heat


Replace the coils on this burner assembly. this will fix this issue you are having at this time.

The coils open and close the valves, which are responsible for gas flow. these coils are damaged.
