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 KENMORE 80 SERIES GAS DRYER. WHEN YOU TURN IT ON IT FIRES UP AND GETS HOT. AFTER A WHILE (5-10 MIN'S) FIRE GOSE OUT AND WILL NOT COME BACK ON.


Hello,
If what happens is the flame comes on when it first starts,after the flame goes off you see the igniter glows then goes off but no flame,the coils that open the gas valve are working while thier cool but once the dryer gets running,when warm to hot the gas valve coils wont open the gas valve so when the igniter comes on and no flame the coils have failed to open gas valve and need to be replaced, all manufactures use the same coil supplied by one parts supplier, and them not opening the valve when warm is a very common occurence regardless of what brand gas dryer it is.
The part number for the coils is 279834 they could be picked up from your local appliance parts store for under $20 or online at;

Dryer starts, runs 10 min. flame shuts off, ignitor comes on again, but gas value does not open. i have replaced the flame sensor, but still will not open gas value.


What's happening is them solenoids are getting hot and when they get hot they fail if they are a bit aged. Replace em and party on.

RHEEM RGLE-10EQAGS Gas Furnace - Intermitent. Fans come on, Hot surface Ignitor comes on, then sometimes Gas Valve opens and all is fine, Other times, gas valve doesn't open and Hot surface Ignitor goes...


The sequence is Igniter comes on, valve comes on, flame sensor senses flame. If no flame is sensed after 3 tries, a lockout occurs. If you have a volt meter, check for 24-27 Volts AC coming to the gas valve, if your getting voltage to the valve but no gas, your gas valve is defective. It could be a intermittent problem, no matter, still a bad valve. if no voltage to valve, defective circuit board.

Dryer won't get hot


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 gas valve coils may have to be replaced. If the gas ignites but does not stay on either the flame sensor or the coils are at fault.

Lights once then not again


Hot Surface ('Glow Bar') Ignition System glow-amin.60x20.gif (most common)
This is the most popular system currently in use and is comprised of a control mechanism (whether thermostat or electronic control), the oven ignitor and an oven gas valve. What happens in this style control system is that the thermostat or electronic control supplies power to the oven ignitor and gas valve which are connected in series (one after the other). As power flows through the ignitor it heats and allows a specific amount of current to flow to the oven valve which is in the same circuit. If the oven valve senses the proper current flow, it opens to allow gas to flow to the oven burner where the glowing hot ignitor (glow bar) ignites it.

Maytag DG482 Dryer Won't Heat


The heat is regulated with a Klixon mounted next to the blower housing near the vent pipe so it can judge the temperature of the air coming out of the drum.Right next to it is a melting type fuse. If the dryer runs and gets too hot the fuse will melt.But the dryer will still run. So if the fuse is good(continuity) and the dryer control(cycle) thermostat is also good then you should have power going to the gas valve assembly when the machine is running unless the timer is in the no heat or wrinkle free/cool down mode. When the gas valve assembly is energized the flame sensor a%20flame%20sensor%202.bmp flame sensor mounted outside the burner chamber detects the heat from the ignitor. When the heat is very intense then the sensor shuts down the ignitor
a%20igniter.jpg Ignitor and that frees up the power so that the coils can be fully energised and open the gas gates. The gas comes out and hits the red hot igniter and you have ignition. It stays on for maybe 2 or 3 minutes or until the control thermostat is satisfied and shuts down power to the gas valve assembly. So... If your gas dryer has a good flame sensor and a good igniter AND the dryer will work some and quit, replace these: dryer%20coil%20kit.jpg Gas operator coils
part# 279834
The coils get hot and quit on these machines when they get a little age on them. It is aggrevating because it is a hard to diagnose thing. But well worth the 20 bucks. SOURCE

How do you light pilot light?


Dryer does not have pilot light.  There is an ignitor that glows when the dryer is started and lights the flame when the gas begins to flow.  With the front of the dryer off start it up and look for the glow. when it glows hot enough (or on a newer model it might be a spark) the gas should ignite.  When the flame sensor sees that the gas is ignited it shuts off the ignitor and keeps the gas valve open until the temperature sensor gets high and shuts it off.  When the temp sensor cools down the cycle repeats.
If no glow or spark-->bad ignitor If no gas flow-->bad flame sensor or bad gas valve coil If gas comes on and goes off quickly-->lint filter and/or vent pipe or outlet may be clogged or bad flame sensor.

Gas dryer don't heat, pilot ok


The ignitor is coming on so that means you have power to the gas assembly. Next the flame sensor should shut down the ignitor when the bi-metal inside it bends from the heat. This kills power to the ignitor, which allows for the power to activate the coils. The coils snatch open the gas valve and allow for ignition. The raw gas hits that screaming hot ignitor and ignites into a glorious flame, raising the temperature inside the drum. While that flame is on, the control thermostat is monitoring the heat within the drum. When the temperature gets to a round 140 F then the power gets killed to the gas assembly by the control thermostat. If all of that seems to be happening for say, the first time, then suddenly the ignitor comes on then shuts down and no flame comes out, then you have weak and intermittant coils. Replace these puppys:
