Igniter heats but gas valve does not open. should the flame sensor close or open to enable valve. could the drum over heat sensor (clickson?) keep it from opening.

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.

My Fridigidaire gasdryer will heat up for the first part of cycle


It sounds like the coil valves are not continuing to open.

If you can get the dryer open, (unit UNPLUGGED of course) you will see that the gas valve has two black cylinders on top of it with wires coming out. Electricity magnetizes these and that magnet is what opens the gas valve so that the dryer can heat. When they get old, the electricity starts to heat them up, and they stop working. You end up with a dryer that will heat up for the first 2 minutes of a load, and then stop heating.

The coils are very easy to replace, and are usually held in with a small bent metal plate and two phillips screws. Removing this plate and the coils doesn't interfere with the gas plumbing, but if turning the gas off makes you feel better, go ahead.

I'm not sure if those are the ones for your model or not, but that is what they will look like. Check the model number on the sticker inside the door to make sure you get the right ones. Be sure to get the kit of 2.

Kenmore gas dryer model 110.76814690 will not heat up


The bottom panel is held on by spring clips. Use a putty knife to access the bottom. The heat is regulated with a Klixon mounted next to the blower housing near the vent pipe so it can judge the temperature of the air coming out of the drum.Right next to it is a melting type fuse.8f17134.jpg If the dryer runs and gets too hot the fuse will melt.But the dryer will still run. So if the fuse is good(continuity) and the dryer control(cycle) thermostat is also good then you should have power going to the gas valve assembly when the machine is running unless the timer is in the no heat or wrinkle free/cool down mode. When the gas valve assembly is energized the flame sensor a%20flame%20sensor%202.bmp flame sensor mounted outside the burner chamber detects the heat from the ignitor. When the heat is very intense then the sensor shuts down the igniter
a%20igniter.jpg Igniter and that frees up the power so that the coils can be fully energised and open the gas gates. The gas comes out and hits the red hot igniter and you have ignition. It stays on for maybe 2 or 3 minutes or until the control thermostat is satisfied and shuts down power to the gas valve assembly. So... If your gas dryer has a good flame sensor and a good igniter AND the dryer will work some and quit, replace these: dryer%20coil%20kit.jpg Gas operator coils NOTE: The coils get hot and quit on these machines when they get a little age on them. It is aggrevating because it is a hard to diagnose thing. But well worth the 20 bucks.

I have a Whirlpool Gas Dryer LGV6848AWO.


the ignitor bar that lights the gas might not be coming on, the coils that open the gas valve in the dryer might not be opening the valve, or the flame sensor might be bad which would not allow power to the ignitor. these are the most common problems with whirlpool gas dryers
