    clean the lint build up inside for the moister sensor will keep the heat in check (shut off) until all vents are clean

Gas dryer heats up runs about 3-5 minutes then quits. Have cleaned all filters, exhaust and sensor with problem continuing


Gas Dryer no heat: or shuts down soon after heating CHECK:

Thermal Fuse
If the air flow in the dryer is restricted, the temperature in the heating chamber can get hot enough to blow the thermal fuse. If the fuse blows, it cuts power to the coils that control the gas valve. The fuse is usually mounted to the exhaust duct just inside the back panel. You can check its continuity with an ohmmeter. If, after disconnecting the fuse, you get any reading other than 0 when you touch the leads of the meter to its terminals, it has blown. There's no way to restore it -- you'll have to install a replacement.

Igniter and Gas Valve Coils
TEST with a multi meter: The igniter is an electric conductor that works like the element in an electric heater, glowing hot enough to ignite gas when you turn on the dryer. This conductor can burn out, and when it does, it may glow, but it won't get hot enough to ignite the gas. At times it may give a reading of continuity yet fail mechanically and not get hot enough to ignite flame though it gets hot and glows and even may show Ohms or continuity ( close circuit) ?

Occasionally, the Gas safety valve and the electric coils that control the gas valve are defective -- they can wear out when the dryer gets old. When this happens, the igniter glows, but gas never enters the heating chamber or does not stay consistant.
Performing a continuity test on either part will help you determine whether or not you need to replace it. But the coils should also be tested for amount of resistance as well as Ohms. As they may be showing ohms yet not putting out enough resistance to keep proper gas pressure flowing. Most coils should show at least 1300 ohms ( GIVE OR TAKE 150 OHMS). Anything significantly less Thus u get an ignition but then it soon goes back out. The flame does not stay lit.

Air Flow and Heat
The motor that drives the tumbler also drives a fan that circulates air through the heating chamber and the tumbler and expels it through the vent. If the air can't circulate, perhaps because of lint blockage, the heating chamber overheats, which prompts the cycling thermostat to turn off the gas. The thermostat resets when the chamber cools, but the chamber heats up quickly and the thermostat again shuts off the gas. The result is that the temperature in the tumbler doesn't stay hot, and your clothes take longer to dry, if they get dry at all.

Warning
There's a big difference between a dryer that doesn't heat up at all and one that just doesn't get hot enough to dry your clothes. In the first instance, the problem is usually a defective part, and things should be back to normal after you replace it. In the second instance, the problem is caused by restricted air flow, and you need to clear the lint filter and vents and take steps to prevent lint build-up. If you don't, you'll use more energy for drying than you need and the dryer may continue to malfunction. Worse, you may have a dryer fire.

Hotpoint nvl333gb5ww gas dryer not drying


Basically all gas dryers have the same setup on the gas assembly which is a sensor, an ignitor, and a pair of solenoid coils. The gas assembly gets its power from the cycling thermostat mounted on the blower housing. As the air moves through the blower the temp is being monitored by this thermostat. Wired in with this thermostat is also a fuse or a thermodisc which trips if the dyer overheats. So if either of these is bad then the gas assembly will not get any power. When power does go to the gas assembly all of the components are powered up at the same time. Why don't the gas come out? Because the majority of the power is being used by the ignitor. Their is simply not enough ampdraw there to open the valve. To open the valve the ignitor must be screaming hot AND shut off. That is the job of the sensor. Once the ignitor is up to temp it becomes a thermocouple. The sensor shuts down power to the ignitor and it generates through a 3 wire on the holding coil enough power to hold the valve open. If for some reason the flame did not ignite when the ignitor cools off the power to the holding coil diminishes and the gas gets cut off. So if the ignitor is doing its thing and the flame sensor is doing its thing then the coils which have been known to get hot and quit need to be replaced. Here is my home video:

Heat turns off while clothes still wet


change the gas coils on the gas valve by removing the 2 screws holding the bracket for the coils,remove the wire harnesses to each coil,dont worry one coil has 2 wires the other has 3 so quite hard to reverse

My dryer doesnt dry very well, what can i do to fix it?


Is that a gas dryer? I think I might know what it is if that is a gas model. The gas assembly consists of flame sensor, Ignitor, and solenoid coils. If the flame sensor does it's jobs and detects the ignitor heat and then it shuts down the ignitor like it is supposed to then the coils should allow gas to exit the valve. Over time them coils get hot and quit. Replace em and party on OR post a model numba fer a betta answer. themobilian_2241.jpg

I ahve a duet gas dryer and it will not get hot


Now did this happen all at once or did it slowly dry clothes slower and slower and then just quit? If it happened slowlt it is because you have some sort of ventalation blockage withing the dryer itself or in the wall of your home. When this happens it will the blow the thermal cut off and this will need to be replaced. If it happened over night then it could be the heating element or the thermal cut off & thermostat. All these can be checked with a volt meter using the setting for continuity.

MODEL PYGT444AWW GAS DRYER LITES UP OK BUT SHUTS DOWN HEAT TO SOON ALONG TIME TO DRY


there is a saftey relay that might be bad and needs replacing.. this is there for keeping dryer from starting a fire or over heateng.. when the dryer start heating the saftey switch is on and once it stops heating the switch is open and and will not dry.. it could be a heating element once it gets hot it expands and will not heat..

Runs and heats but will not dry


Fist need to know if it is gas or electric dryer, it makes a difference.

If an electric dryer, It is possible that one of the heating elements has failed (burned out), which would still allow the other one to get hot, but not enough to completely dry the clothes during the normal timed or automatic drying cycles.

You can check this with an ohm/amp meter if you are comfortable with working around 220V-AC voltage, etc. You'll need to remove either the rear cover, (if your unit has rear access) or the top of the dryer and then the drum, to gain access to the electric drying elements. This depends on which model you have and how old a dryer it is, etc.

Once you've done that, you can sometimes see a broken drying element, if not, you can check for continuity with the ohm meter (make sure the power cord is unplugged!).

If you are unable to determine with this method, you can restore power and briefly put the dryer into a timed dry cycle (drum and drive belt removed, while you visually check for heating elements turning red/orange as they heat up. Only do that long enough to confirm which element is good, be very careful, as they get extremenly hot. Once you know which one is bad you can order your replacement by model number , etc. Hope that helps.

Heating Problem


If this is a gas dryer, you probably have bad valve coils, they can work intermittently, usually for the first part of a cycle, but when they heat up the internal resistance gets too high and they fail to open the gas valve. Once they cool off, (by continuing to air dry) they will work again for a few minutes. They will also make a buzzing/rattling (maybe "metal" ) noise as voltage is applied. For any Kenmore gas dryer, get part #279834 it contains both valve coils. Very easy to replace. Another possibility is that your duct work is plugged, check airflow. Hope this helps.
