Hi,

If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.



if you dryer is gas check out this gas no heat tip....



If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.

Will start, clothes will tumble but will not heat up to dry the clothes


Run it with the vent off if you feel some heat for the first minute and the airflow is strong you best bet is to change the valve coils.The vent is not a part in the dryer the vent is was connects to the back of the dryer pull the vent off and run the dryer to test.
The coils are on the top of the gas valve.

Gas dryer with no heat: The parts that I have pointed out with the arrows are the parts that you will need to check with an ohm meter if the dryer is not heating. First check and see if you have 110 volts coming to the gas valve at this type of a connector. If you have voltage, then unplug the dryer and check the parts I have pointed to. Some dryers have 3 coils instead of the 2 shown here. If you do not have voltage coming to the burner, then you will need to check the timer contacts that feed the gas burner, hi limit thermostat, operating thermostats, the safety switch on the motor, and any other point that you can see on your wiring diagram picture that feeds voltage to the burner. The coils on the gas valve are very bad for working once or twice and then quitting. If you find a open circuit on one of the gas coils, replace them all = less problems later on. If the glow coil does not work ( get red ), check it with a ohm meter for continuity. The next thing to check if the glow coil does not come on would be the radiant sensor. Inspect the igniter for small burnt spot on dark gray or black part of igniter or check for 110 volts to igniter wire plug when dryer should be calling for heat. Sometimes the ( older style ) igniter is separate from the holder and the holder can no longer hold the igniter tight enough and the two parts burn/arcwhere they touch each other = new igniter and holder ( some manufactures have new kits to replace these older style parts ).
Does the igniter get red and stay red, or does it get red, you hear a click and it goes off, then a minute later its gets red again?....if so you possibly have a bad set of coil valves. If the igniter gets red and stays red constantly then its the flame switch that is bad and maybe welded closed.

Sg7800 maytag dryer stopped giving heat


Sounds like burner not igniting. On front of dryer in the lower right there should be a gas valve/burner access panel. Usually you just have to pry out at bottom of panel & swing out and up to remove. This gives you access to valve coils and igniter. With panel removed set timer for heated dry and start dryer, observing first the igniter which should glow bright orange-red, then after a couple seconds you should hear a "Click" which is gas valve opening and a blue flame ignites for heat. If no glow is seen after a few seconds or at least a minute, igniter is bad, if it does glow and no click is heard from the gas valve, the coils (electro magnets) on the valve are bad, or the "Flame present" sensor is bad. Chances are it's either the coils or igniter.Try this on all heat settings, if you get heat at only one setting it might be in timer contacts, but not common. Again you can repair/replace both the igniter (usually just plugs into a receptical) and the coils (2 donut looking objects on the gas valve, replace both.) Access door may be on back if not on front, but normally their on lower right of front.

Maytag gas dryer. Heating element comes on however, not every time does the gas click on so I get heat. Gas line is fine. What causes the click that gets you heat for dryer?


That would be the "igniter" you hear. You may have a problem with the igniter or the 2 coils on the gas valve. Below are links to the parts.

My whirlpool gas dryer model no LGR7646A has no heat, not sure iof this has a pilot or not, if not could it be some sort of safety switch taht shut down the dryer


I am 99% sure it is electronic ignition. There a dryers that had pilots but those are very old. So what you can do is start with the basics. Make sure the gas valve for the dryer is on and there is gas pressure coming from the connector. Make sure there is no debris blocking gas flow in the gas line. If the dryer has a removable door or burner inspection hole on the bottom pull it loose with a screw driver otherwise you will need to remove the back cover of the dryer. Turn on the dryer and watch for the hot surface igniter to come on. It will glow very bright then you should hear the gas solenoid valve click and the burner should come on. If the solenoid opens and the igniter does not come on inspect the burner orfice for any blockage. If the igniter does not come on then you will need to test the igniter for the proper ohm reading with a fluke meter. You will need to verify the igniter is getting power. If the igniter tests good it might be a bad solenoid valve(there are two) or a grounding issue.

My GE Dryer, model number Model# DSXH43GV1WW doesn't heat up anymore. The dryer turns on, the drum spins, in all the three types of available cycles, just no heat at all. Any ideas?


First make sure that the gas valve is on. Then verify that the gas connector is not kinked or restricted. then remove the connector at the back of the dryer and make sure there is gas pressure. Then visually inspect the pipe at the back of the dryer. Use a flashlight to inspect inside the pipe and make sure there is no debris inside the pipe that could restrict gas flow. On this dryer there is no removable burner door cover on the front or inspection window so you will need to remove the back panel of the dryer. Once the panel is removed you can turn on the dryer. You should first hear a click sound. That is the first gas solenoid valve opening. Then the igniter should start to glow. Once the igniter reaches 2200 degrees the secondary gas solenoid valve should click and the burner will come on. If you do not hear a click when the dryer is first turned on you will need test the first gas solenoid valve. Make sure it is getting voltage with a fluke meter. You can also touch a piece of metal to the top of the valve and the top should be magnetized when active. If you hear the first click but no igniter glow then verify the igniter is getting voltage and test the igniter with a fluke meter. You will need to test the ohms and most should be 500 to 700 ohms. If the igniter does not get a good reading or none it is probably defective and needs replacement. Usually most places that sell appliance parts will test the igniter for free. Just because the igniter glows does not mean that it is good. It can glow but not reach the 2200 degrees needed for the proper operation. Now if the igniter is good and you hear a second click then there might be a restriction somewhere in the gas line between the solenoids or the gas orfice at the burner. The sensor Gort was talking about is the flame rectification sensor and can detect the flame. It is rare for this to be faulty but not impossible. If you get flame for a couple seconds and then it shuts off it could be this sensor. Blow the burner assembly and this area off with compressed air and lint can block the sensor's ability to detect the burner flame. Also I believe your dryer has a larger fan blower than standard dryers. If this blower motor is not working the rest of the system will not come on. make sure the assist fan is working and that the vacuum switch is working and not stuck. Also check the vacuum line is not disconnected or restricted. And always remember that there are exposed power connections inside the dryer that could shock you and cause injury. use caution and if you do not feel comfortable working on this you might want to call a professional.

Things that could stop a gas dryer from heating:
- glow bar igniter, thermal fuse ( not all models ), coils on the gas valve, gas valve, thermostats,motor heat switch, timer, selector switch, sensor.

Pilot Light? Are you sure? All the gas dryers I've ever worked on were pilot-less. There should be a glow-type igniter that heats up when the dryer is turned on. When it reaches a certain current potential a gas valve is opened and the burner ignites. How old is this dryer? Maybe this is something I've never seen before. Is the dryer working at all? If not, here's a way you can narrow down the possibilities of problems:


You need to gain access to view the inside of the dryer, first. With the dryer plugged in, push the start button. If you hear a "click" and the igniter still does not come on, you probably have a bad igniter. If you don't hear a "click", the radiant heat senor is probably bad causing the igniter not to glow. You have to listen very carefully for the clicking noise, though. It's not very distinct with some dryers. Now, the igniter can glow sometimes and still be bad. The way your dryer works; it looks for a certain current potential (roughly 2.7 to 3.2 amps depending on type of igniter) on the igniter before the gas valve opens to ignite. If the igniter is weak, the gas valve may not open. This is a safety feature that prevents gas from leaking into your home. I hope this may help you. Let me know if I can assist further.

After a few heating cycles the burner does not ignite


The problem you are describing is usually associated with a bad gas valve coil. The dryer runs normally until it gets hot, then starts making a strange clicking noise. After it cools down, the dryer runs normally again. The gas valve coils (there are two of them) usually run about $20 a piece. I recommend replacing both of them at the same time just to be sure. I hope this helps.
