    I can turn my dryer on and it tumbles, but it doesnt heat. After taking a look inside of the dryer, with the front panel down. I noticed that after about 20 sec the heat lamp comes on but theres no burst of flame. The lamp stays on for about 10 secs and then goes off. I turned the gas line off and then turned it back on and still no heat.... Need a solution

Depending on the model, you may have a gas vale problem. The ignitor is working but gas is not being allowed to flow to the burner. It could also be one of the temp sensors or the control board for the system. Try unplugging the dryer and then replugging it back in after a few minutes.. If that fails to work after that.. provide brand and model so we can provide more detailed assistance...

Hello Friend, Your problem is very simple to fix. You're dryer needs a thermal fuse and or gas valve coils, and maybe an igniter all three are very simple and affordable to replace. To replace the thermal fuse just remove back cover of dryer and look down where the air blows out. Now, just to the left where all the wires are you will see a white plastic part with two wires plugged into it. This part is called a thermal fuse. Just remove these wires and replace the thermal fuse. Now, if this don't solve the problem you will need a gas valve coil kit. To replace coils just remove front of dryer body and look below drum you will see the gas valve. The valve coils are located on top of valve (two little round black cylinders). It's simple, just remove the two screws from the little metal bracket that holds them down, unplug the wires from them and just lift them straight up off of the valve. Take notice that one has 3 wires and one has 2 wires. Just replace with new coils and plug wires back in and re-fasten metal bracket. Your dryer will run like new, if it doesn't then you will need to check the igniter. The igniter is attached to the end of the burner assymbly by one screw and a simple two wire plug. Inspect for breakage, and replace if needed. Happy to help, Tim.

Warning! To avoid personal injury or even death, always disconnect your appliance from its power source--that is, unplug it or break the connection at the circuit breaker or fuse box--before you do any troubleshooting or repair work on your appliance. Also, because some components may have sharp edges, use caution while working on your appliance.

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. Once you access the site you will be able to navigate numerous pages of information on your product. You will need to enter your model number to access your product information.

Here are some things to look for:

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.)

It could be the ignitor, you have to open the dryer, take the belt off and start it, if you dont see a red glowing light could be the igniter, you have to disconect it and check for voltage, if you have voltage, replace the igniter

SOURCE: Amana ALG443RAW Gas Dryer will not heat up.

you can remove the lower acess panel (2) 5/16 screws along bottom. youll get a good view of workings there. turn on dryer (make sure a heat cycle is selected. you should see the ignitor light with in a few secs. if not unplug the ignitor(small white connector maybe 6inhes back from ignitor itself) and with a meter ck for 110v in that connection when unit is turned on, if you do have 110volts , you hav abad ignitor. ifyou dont get 110 volts you need to check the thermostat(s) located on top of the heater box right above the ignitor, if no continuity you need a new thermo.

SOURCE: dryer won't heat

i am sending you all the possibilities for your problem, check either of these causes ----and than let me know if it is solved----

Power from the house
Check to see whether there's power getting to the dryer. Is it plugged in? Check for blown fuses or tripped circuit breakers--your dryer uses two fuses or circuit breakers. The dryer could tumble but not heat if only one of the two fuses is blown. If you have circuit breakers, one of the two circuit breakers can trip, even if the two for the dryer are connected.


Heating element
Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable.


Thermal fuse
On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.)


Wiring
A common problem is for the main wiring connection from the house, at the dryer, to burn and break its connection. Because the dryer can still tumble with partial power, the connection may be only partially defective. You may need to replace both the power cord to the dryer and the terminal block inside the dryer that the wire is attached to.

SOURCE: kenmore gas dryer wont heat up

Check the following areas to combat this issue. the most common problem spot will be a blown Thermal fuse.


1. Gas valve coils
Igniter glows, then shuts off without igniting gas - the problem is probably with defective coils (black, located on top of the gas valve). It is recommended to replace all coils (usually two or three) if found defective.

Note: Sometimes the whole gas valve may be defective, thus not letting the gas out. However, this problem is not common.

2. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse.

3. Igniter
Igniter may burn out or break. Replace the igniter if found defective.

Note: Igniters are very fragile and break easily. It is recommended to handle the igniter only touching the ceramic part of it (usually white in color).

4. Flame sensor (or radiant heat sensor)
Replace the sensor (located near the igniter) if found defective.

TUMBLE DRIER STOPPED HEATING


Gas dryer?

If so, probably bad gas solenoid valves. They can safely be replaced without fear of releasing gas. Two phillips screws, two pull off wire plugs. That's it. Cost about $30 bucks depending on where you buy them. They are a universal part and will fit 99.9% of machines.
