Question about Dryers

The igniter lights. The gas comes on and ignites. The problem is the flames go out after less than a minute. I checked for lint build up and there was none.

Does the air blow out of the vent when running? Even without heat.. Sounds like the vent pipe maybe partially or mostly blocked. If all clear, maybe a bad sensor.

I would look for air restrictions. Improper air flow will cause overheating. This will cause the components to shut down prematurely.The igniter lights. The gas - themobilian_133.jpgthemobilian_134.jpgthemobilian_135.The igniter lights. The gas - themobilian_136.jpg><img src=

Heater is cycling on and off, less then one minute cycle time between cycles. Sometimes SPK code comes on and stays on without firing. Have shorted water press switch with no effect. Pretty sure gas...


The SPK Code, indicates that there is power to Igniter and should be producing a Spark to ignite fuel! If this is actually the case, then it is NOT a safety sensor issue, The igniter serves a dual purpose: produce a spark, and then CONFIRM a flame is consuming the fuel. If it does not get a proper Milivolt reading, then gas valve will shut off, hence a cycle occurs. Not enough reading is the same to the heater as no reading! Safety issue. If gas valve stays open, and no flame to consume raw fuel, it will build up and accumulate then when ignition takes place, it go...BOOM! Not Good.
Either insufficient fuel supply/pressure or faulty igniter. It's also not a Gas Valve. It's a simple switching valve, either open or closed.

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.

Gas dryer does not heat


A gas dryer is nothing to mess with if it does not fire up the flame. Pull the lower kick plate off the front of the dryer, unplug the unit and clean out dust/lint build up. Vacuum as needed.
Then after checking that the gas valve that is connected to the end of the gas line that connects from the dryer to the wall, I recommend you get a professional.
Common failures are the pilot / ignition system / thermocouple.
No way to be more specific unless you provide the brand and model number of your dryer.

Intermittant Heat on Gas Dryer


Check the venting tube. It maybe clogged full of lint somewhere inside of it. If so the moister contro sensor will shut off the burner within due time such as yours

Rheem powervent ignites then goes out, electronic ignition.


Sounds like a bad thermocouple. This part sends a millivolt signal to keep the gas valve open but shuts it off when it cools - or if something goes wrong with the ignighter - to prevent fires. It's easy to replace and not super expensive. See your local Rheem dealer.

Rheem gas furnace pilot lights, but no burners or fan


If the burners do not fully ignite, the sensor will shut the furnace down. The lack of sufficient burner flame is a gas valve or gas pressure problem within the valve.
Replacing the gas valve with the original one may get you going. I surely suggest a professional service company for safety reasons and a thorough inspection. A 20 year old furnace is past it's normal life span.
