The gas valve must sense the burner is going or it will shut the gas back off, this information comes from a temperature sensor that in most dryers is part of the gas valve.

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 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.

No dryer heat


If the coils are bad the unit will light with flame for 4 - 8 times then all of a sudden the ignitor will glow, kick off with no gas coming threw valve. it sounds like the high limit thermostat is short cycling the flame. This is the thermostat that sits on top of the burner chamber. remove 1 screw from the thermostat and blend it upwards away from the heat. Then plug unit back in and test to see if the flame stays on longer. Click here to see maytag dryer no heat posts. Contact me anytime here. Hope this helps..

Stops and all the lights come on


Instructions
    • 1 Make sure the home's gas supply valve is turned on. Check your Maytag owner's manual to find the location of the dryer's gas shut-off valve. This is usually behind the dryer's front panel or in the back of the unit. Open the valve to allow gas to flow into the dryer.
    • 2 Open the lower front panel of the dryer to access the pilot light assembly. Press and hold the starter button as you light the pilot with a handheld lighter. If you have trouble getting it to light, release the starter button and wait a few minutes before trying it again. Once the pilot is lit, hold the starter button down for another minute to make sure it will stay burning.

    • 3 Close the dryer's front panel and run a test cycle to see if it is producing heat. Call a repairman to evaluate the problem if lighting the pilot did not restore the heat.

Ignition works but doesn't stay on long enough to heat dryer


its either the hi-limit switch is weak on the burner tube,or the gas valve coils on the gas valve are weak and can no longer keep the gas valve open to supply gas,if they appear warm after operation they are most likely bad

Dryer heats once or twice then stops heating


It's likely one of the coils is opening a break in the coil as the coil heats up. This coil will shrink when cool and be able to run again. The number for the coil kit, which will replace ALL the coils, for your machine is 12001348.

Disconnect power and turn off gas before working on this dryer. Working on gas dryers is not recommended for people who are not professionals.

Service on gas appliances should be undertaken by professionals only due to the danger of gas leakage which can cause fires or death by asphyxiation.

The disassembly procedure is covered beginning on page 3-10 of the manual listed at the link below. Operation and replacement of coils is covered at page 3-32. Replace All coils with Kit Number listed above. Take care not to touch or hit the ignitor or you will be replacing it also. It is VERY brittle.


Reverse process to re-assemble. Good Luck

Dryer start up fine then the gas turns off as ignitor continues


Hi Jim. Perhaps this will help you.

The burner assembly consists of the gas valve, the igniter and sensor, and the thermostats. The gas supplied to the appliance is turned on and off by the gas valve, as follows:


  • First--when you close the dryer door, set the timer, and press or turn the Start button--the motor starts. When it reaches full speed (in about a second) a switch on the motor turns on, which allows the electricity to flow through a simple thermostat to one side of the gas valve.

  • The gas valve then sends power to the igniter, which glows bright orange.

  • As heat and light from the igniter warm up a sensor that's right next to the igniter, the sensor circuit opens, then supplies power to the other side of the gas valve. This completes the circuit and opens the valve.

  • Once the valve opens, the gas rushes out and the igniter ignites it. As the gas burns, it keeps the sensor warm, which keeps the gas flowing.

  • When the dryer reaches the pre-set drying temperature, a simple thermostat turns off the flow of electricity to the gas valve and therefore turns off the gas.

  • When the temperature in the dryer falls about 20 to 30 degrees, the thermostat again allows the electricity to flow through to the gas valve, and the cycle starts over.

If you selected the Automatic setting, the cycle continues until the clothes are dry, then the timer advances and turns the dryer off.

If you selected a timed setting, the cycle continues until the time has expired, then the timer turns off the dryer

My maytag gas dryer ignites when you first start the ctcle then after 5 minutes the flame goes out and wont fire back up. I just replaced the ignitor and that heats up but no gas. if you wait a while it...


Hi, You will need to change the coils on top of the gas valve. The y will over heat later in the cycle and not open the gas valve.
Change them and you will be good to go. Please let me know if this helps you ir if I can assist you further,

Thanks

Dryer heats randomly..Igniter is working.


Generally operation when cold that worsens with use indicates a component that is failing when hot. Start at the burner with the coils and work your way back to relays on the control. Sounds a lot like a bad coil on the burner. I have seen these do 2 complete loads then fail. Setting over night and cooling off will work again the same way. Intermittent conditions are a real challenge sometimes.
