Question about Dryers

Gas dryer not heating properly, burner ignites at start up, then not again

I posted this problem earlier and received some solutions; however, it seems that I may have a faulty flame sensor or thermostat. What voltage or ohms readings do I look for to see if these components are not working correctly?

Please provide the brand and model number of your dryer.. However.. you state that your dryer is not heating properly and yet the burner ignites.. If you have a flame after ignition and your dryer is drying slowly, I would be inclined to look at the blower and or vent for restrictions in air flow. The heat generated by the burner will not be optimized in terms of drying clothes if you do not move that air out . Any and all restrictions to normal vent flow will make the dryer less efficient and dry times will be longer. If you are bound an determined to get into the flame sensor and thermostat logic, then please provide a brand and model number..
Hope this helps...

How do I light gas dryer


Thank you for your post, friend!

Typically, you would not have to light a gas dryer. The Frigidaire dryer has a burner and igniter already installed within the dryer that would automatically start. If you are not receiving heat you may need to seek assistance from a professional technician for proper diagnosis and repair. This would help avoid any future issues for your dryer. -Matt

I have a siemans wtxd5522uc 27" ultrasense gas dryer that the ignitor won't fire. What is the supply voltage to the ignitor? Is it usually the ignitor that goes or some sensor? Every thing else...


hi sir it ignites at the voltage bet 230v-250v.there will be a sensor problem where it cannot try to ignite try to clean ignitor area.. In a gas dryer, heat is provided by a gas heater that is controlled by an air shutter. The gas heater is generally the source of no-heat or drying problems. You can often correct such problems by adjusting the air shutter on the gas burner, which is located along the bottom of the dryer.
To adjust the shutter, take out the screws and remove the panel that covers the gas flame. Turn on the dryer so the flame is burning. If the flame has a deep blue color and you hear air whistling around the burner, the air/gas mixture is receiving too much air. If the flame has a yellow tip, the mixture is not receiving enough air. Turn the thumbscrew or loosen the two screws slightly to increase or decrease the flow of air to the burner. Keep turning until the flame is a light blue color, without any yellow, and the whistling stops.

Gas dryers use an electric ignition device rather than a pilot light to light the gas heater: An element becomes hot and glows like the filament in a lightbulb. Electric ignition systems are always sealed; you can't adjust or repair them. If an electric ignition device fails, call a professional service person for replacement.

My dryer is not heating when I turn it on the glow plug comes on but does not ignite the gas


The most common cause of a no heat problem on a GAS dryer is worn or blown igniter. These appliances are equipped with a burner assembly with electronic igniters. The following link explains a little theory about how these igniters work:

http://www.fixya.com/support/r401858-replacing_oven_igniter_gas_range

I know the link is for a gas range, but the burner assembly functions are nearly identical, as well as, the type igniters used.

If you are having ignition problems it is probably a simple matter of a weak or bad igniter. The burner assembly will ignite automatically as long as the gas valve, igniter coils and igniter are all functioning properly. It can take up to 90 seconds for the burner to ignite. As the igniter ages, you may experience longer ignition times.
NOTE: Just because the igniter glows, does NOT mean it is good. An igniter may still glow, but could be too weak to properly operate the gas safety valve.

Replacement parts can be purchased at any of the following websites:
searspartsdirect.com pcappliancerepair.com appliancepartspros.com repairclinic.com All these sites have competitive pricing, so shop and compare. The first three sites listed also have helpful exploded view parts illustrations to assist you with locating and properly identifying any parts you may need.

If you have any questions, please post back with your complete MODEL NUMBER and let me know. I hope this information is helpful to you.

The gas valve coils are getting weak. Replace the gas valve coils.

Gas dryer not heating properly


This sounds like the flame sensor is bad to me.

If it does not work properly, the unit will shut off for safety. The machine assumes that the burner did not light and rather than run gas into your house, it shuts off. It may try to start a certain number of times and then shut off.

You may be able to remove and clean it (flame sensor) lightly with a scotch brite pad and it may work properly again.

Otherwise it will need replacement.

This is a very common problem and the part is probably in stock.

Post a comment on your progress as this solution is likely to be useful to many people.

Thanks,

Tim

The problem is not the gas valve.

Below is a link to common solutions that will help you with parts and diagnostic procedures that are specifically tuned to your manufacturers data plate information.
It provides exploded view imagery, belt routing diagrams, parts imagery and function, parts ordering and shipping information, error code details, just about anything you need to get your appliance up and running again.


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.

If this doesn't help, post me back and I will do some more research to help resolve your issue.

If your dryer doesn't heat, check these:

Igniter
Gas valve coils
Thermal fuse
Igniter Modern gas dryers use an electric igniter to ignite the gas from the gas valve. When it's working properly, the igniter glows bright orange. When it burns out, the dryer tumbles but there's no heat because the gas can't ignite. When the igniter burns out, you need to replace it. If the igniter is held by a tension bracket, you very well may need to replace the bracket too.

The igniter is inside the dryer housing, near the bottom front, usually in a cone-shaped metal tube (the force cone). It's about 2 inches long. It's mounted to the far end of the burner tube, and it has two wires attached to it--or to the tension bracket, if there is one.

Gas valve coils Watch the igniter. Does it glow bright orange, then shut off without igniting the gas? (When the gas ignites there's a large blue flame.) If so, there may be defective coils on the gas valve. Mounted on the top of modern gas valves, there are black electrical coils. The coils, when energized, open the gas valve. If one or more of the coils are defective, the valve doesn't open and the gas cannot ignite. Because it's often difficult to properly test the coils, it's usually best to replace both (all) of them at the same time.

Thermal fuse On many dryers, there's a thermal fuse (a heat-sensitive fuse that blows if the dryer overheats) mounted to the exhaust duct inside the back cover panel. The fuse is about an inch long. It's usually embedded in black resin and mounted in a white plastic housing.

If the fuse has blown, it has no continuity. When this happens, your dryer either just stops heating, or it doesn't work at all. Be sure to inspect the venting/heating system before replacing the fuse to put the dryer back into operation. (You can't re-set this type of fuse.)

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.
