Question about Dryers

1 Answer

My gas dryer starts and runs ok except the heat is inconsistent. When heat is called for, ignitor glows but secondary gas solenoid fails to open for several (between 4 and 7) cycles. What can I look for or replace to correct this problem?

Hi,
As crazy as this sounds your ignitor is going bad...

The most common problem with a gas and no heat is the ignitor going bad...

I have a GE gas dryer DBVH512GF1WW. The heat is inconsistent. I noticed the ignitor glowing and then a flame shortly after on the initial time I turned the dryer on. Then after the flame going out after...


sounds like bad gas coils located on top of the gas valve,when the coils start to fail the ignitor will glow,the coils let the gas in until the coils heat up and then ignitor glows but no gas.when the coils cool down they might work again for a short time until they heat up and fail again.if the flame lights and goes out after like 30 seconds and goes out and keeps doing this you have a block either in the dryer or the vent line but it sounds like you have bad gas coils.unplug the dryer,get at the valve,pull off the wires going to the coils and check them with a meter,one should be open,just remove the two phillips screws pull off the cover and slide the coils up off of the posts,unplug them and put the new coils on,you'll see like a little piece of plastic on the top of the coils,this fits intoo the cover so they line up correctly and holds them in place,also on the larger coil there's a spacer on the post,if you don't see it look inside the old coil,poke out the spacer and slide it onto the post and then install the coil.

My gas dryer keeps shutting down the heat cycle and I have changed the hot surface ignitor


The gas valve assembly consists of the ignitor, the flame sensor, and the solenoids.
In order for the gas valve assembly to operate, the ignitor must come on, the flame sensor must then shut the ignitor down in order for them solenoids to activates. Them selonoids won't activate untill the ignitor is glowing. Once the ignitor is glowing, it then acts as a thermocouple though the secondary winding on the primary solenoid. As long as you have igniton the ignitor keeps the power to them solenoids on. If fer some reason the gas did not ignite, then after the ignitor cools back down the gas would be shut down and that is your built in safety. So what goes wrong? With a bit of age them solenoids work a little then overheat and quit, making it a very difficult diagnosis. But now you know the secret right?
Swap out them lame solenoids and rock on!

I have a 7yo Kenmore Elite gas dryer w/no heat. I tested all the possible culprits with my ohmmeter. I found the ignitor was not glowing so I replaced it. Now it glows but I still have no heat


The glowing if the ignitor indicates that the circuitry is good but the flame/radiant sensor is bad and/or one or both of the gas valve solenoid coils are not working. The flame/radiant sensor bypasses one the solenoid coils then when power is applied to the ignition circuit, the first coil opens the first valve, the ignitor glows and the flame/radiant sensor gets heated. It's contacts then opens when heated enough to unbypass the second coil and allow the gas to flow and be ignited.

Make sure the flame/radiant sensor is properly in place and aligned with the ignitor to allow proper heat sensing. You may check the continuity between the sensor's contact terminals as the ignitor glows. At first, the terminals should read close (zero resistance) and then open (infinite resistance) after about 30 seconds or so. If this is not the case, the sensor is not working and must be replaced.

The solenoid coils, one with 2 prongs and the other has 3, sitting on top of the gas valves must be both replaced if the flame/radiant sensor turns out good. But before doing so, make sure to run a test with the dryer completely assembled because sometimes the gas do not ignite when the dryer's cabinet is open. This is to prevent unnecessary replacement of the coils.

Feel free to update us about the result and if you need further advice.

I have an Amana Dryer Model # LGD20AW and when the dryer is first turned on the glow plug will heat up and ignite the gas but as the dry cycle continues the glow plug will heat up but no flame will ignite...


The glow coil or glow bar heats up and a sensor on the side reacts to the heat and then sends a signal to a gas valve.(solenoid valve) When the gas doesn't ignite when the coil is glowing... here are some reasons. 1. The sensor on the side of the burner assembly isn't working or sending power to the valve. 2. The valve is getting power but not opening. 3. The ignitor is not glowing hot enough to activate the flame sensor. Usually it is the sensor or the igniter not the valve.

Dryer will not heat up


Unlike electric dryers gas dryers will continue to run if the thermal fuse is blown. Usually some sort of air blockage will cause the thermal fuse to blow. The control thermostat powers up the gas assembly.cd79cfa.jpg It judges the drum temp as air passes over it on its way out the exhaust. It opens(quits sending electricity to the gas assembly) at 160f for cotton and closes(starts sending power to the gas assembly) again at 105f.
When the dryer is running and the timer is set for heat, the control thermostat is energised. It powers up the flame (ignitor) sensor, the ignitor, and the solenoids. The gas does not come out with those solenoids energised because the ignitor is using most of the power to get it lit. When the ignitor is glowing wide open the heat from it causes a bi-metal in the flame/ignitor sensor to bend and open the circuit to that ignitor. That kills power only to the ignitor. The resulting power surge causes the solenoids to yank open them flood gates and raw gas comes out onto that screaming hot ignitor. KAWOOOSHHHH Houston we has ignition. At this point the ignitor becomes a safety device. As long as the flame is washing through that ignitor the current keeps flowing to them solenoids and the gas keeps a coming. If for some reason their was no ignition the ignitor would cool down and shut off the solenoids. More here

How do you relight the pilot on a kenmore 80 series gas dryer?


Their is no pilot light. The system uses a glowbarce9a48b.jpgOPERATION
The newer dryers use a silicone carbide ignitor for ignition. If the Fuse is ok482c508.jpg the gas assembly gets power from the control thermostatfa8083a.jpg. The flame sensor allows the ignitor to go cat go. The coils themselves10e9e78.jpg cannot open the gas because the ignitor is using a lot of power. When flame detectc5ddc7a.jpg gets warm enough then it shuts down the ignitor and power is redirected on the other side of the 3 prong coil. The ignitor is not finished. It now is hot enough to act as a path to the secondary coil which energizes and sends that raw gas to the 1800f screaming hot ignitor. Igniton occurs and keeps the ignitor hot. If ignition at this point were to fail the ignitor would cool down and shut off the power to the secondary coil. Clever ain't it? So what can go wrong? Worn out flame sensor takes longer to reset, ignitor open. Clogged vent012c9c0.jpg overheat fuse blown, bad thermostat, and faulty solenoids.If all is good it should continually shut on and off all during the cycle to regulate the heat

Starts up and runs but there is no heat ,have gas supply but burner does not fire ,looks like i ahve voltage to all componets except to the hi heat thermostat


check the thermal fuse in the dryer vent conduit near the exhaust vent,then the cycling and high-limit switches/thermostats,your radiant sensor on the burner tube,your glow coil that ignites the gas,and finally your boost and secondary solenoids on the gas valve for continuity

Dryer runs, tumbles and is putting out air, but the it won't automatically shut off and is not heating up. Suggestions please????>


If electric then the thermostat or the heating element has failed.
If gas: First thing to check is the ignitor underneath the drum. (You have to open the panel to see it) It should glow shortly after the dryer starts, then the flame starts and the ignitor shuts off. If the ignitor does not glow then it or the thermostat is bad. If the ignitor is glowing but the gas does not light then the flame sensor may have to be replaced. If the gas ignites but does not stay on either the flame sensor or the coils are at fault.

Make sure the lint filter and the exhaust vent pipe are not clogged.

No Heat on a whirlpool dryer. 14 years old.drum turns,timer moves,getting gas to valve,tapped solenoids-no change.burner not lighting. thanks for any info


if ignitor not coming on could be flame sensor mounted on side of burner housing or ignitor ..if ignitor glowing but burner no lighting replace both solenoids bad connections interally on solenoids..also if ignitor not glowing possible small white thermal fuse open.. sensor and fuse can be jumped across to confirm ..
