Question about Dryers

1 Answer

I have a JC Penney dryer that is very slow drying cloths. The Igniter and Gas Valve are both working. When I turn the dryer on I can see the burner light but it only stays on for about 15 seconds before it goes out. After about 1 1/2 minutes the Igniter lights up and the burner comes back on for about another 15 seconds and then shuts down. It repeats this cycle over and over. Is the problem with the Thermal Fuse or Radiant Sensor or is there another problem. Thanks for your help.

HI, First thing you want to check is your venting to the outside. Make sure it is clean all the way out and that it is not pinch/kinked. Please let me know if I can assit you further.

THanks

Will start, clothes will tumble but will not heat up to dry the clothes


Run it with the vent off if you feel some heat for the first minute and the airflow is strong you best bet is to change the valve coils.The vent is not a part in the dryer the vent is was connects to the back of the dryer pull the vent off and run the dryer to test.
The coils are on the top of the gas valve.

Gas dryer with no heat: The parts that I have pointed out with the arrows are the parts that you will need to check with an ohm meter if the dryer is not heating. First check and see if you have 110 volts coming to the gas valve at this type of a connector. If you have voltage, then unplug the dryer and check the parts I have pointed to. Some dryers have 3 coils instead of the 2 shown here. If you do not have voltage coming to the burner, then you will need to check the timer contacts that feed the gas burner, hi limit thermostat, operating thermostats, the safety switch on the motor, and any other point that you can see on your wiring diagram picture that feeds voltage to the burner. The coils on the gas valve are very bad for working once or twice and then quitting. If you find a open circuit on one of the gas coils, replace them all = less problems later on. If the glow coil does not work ( get red ), check it with a ohm meter for continuity. The next thing to check if the glow coil does not come on would be the radiant sensor. Inspect the igniter for small burnt spot on dark gray or black part of igniter or check for 110 volts to igniter wire plug when dryer should be calling for heat. Sometimes the ( older style ) igniter is separate from the holder and the holder can no longer hold the igniter tight enough and the two parts burn/arcwhere they touch each other = new igniter and holder ( some manufactures have new kits to replace these older style parts ).
Does the igniter get red and stay red, or does it get red, you hear a click and it goes off, then a minute later its gets red again?....if so you possibly have a bad set of coil valves. If the igniter gets red and stays red constantly then its the flame switch that is bad and maybe welded closed.

Dryer seems to run fine but does not get hot. (72882 series)


The cause of a gas dryer not heating can be many things. You need to diagnose the problem starting at the gas valve from the wall all the way through the dryer to the burner. Is the gas on? You may remove the flexline and check for gas. Reattach the flexline and see if the igniter is firing. It could be a faulty igniter. there are temprature limit switches that check if the dryer is overheating, if they get too hot, the dryer turns off the burner. switches are about the size of a quarter and there are usually two or more. One is a lower limit and the other is an upper limit switch The switches go bad after a while because they heat and cool many times over their lifetime. The way to check if it is a limit switch is to remove it from the circut and bypass it temporarily to see if the burner fires. If it is not a limit switch, it could be the gas valve. The valve is the brains and costs about $100 generally. Sometimes the valve can stick and believe it or not a good wack can unstick it.
Good luck....

My dryer is not getting my clothing dry. what could be the issue of not drying my clothing?


Blocked air vent. Check where the vent exits to the outside, as usually condensation builds up on the "bird blocker" which attracts dust, which attracts condensation, which attracts dust... etc.

Gas valve coils. The gas valve is opened by two electromagnetic coils. When they start go go bad, they will open the gas valve in the beginning of the cycle, then as the current heats them up, they will quit working, and you will lose heat partway through the cycle.

Igniter. The gas is lit by an electrical lighter similar to the cigarette lighters cars used to have. If the igniter breaks, then the gas valve coils don't turn on, and you get no heat at all.

Dryer blows cool, not hot, air


Clean the burner exhaust and intake vents of dust and lint. Make sure the gas is turned on to the machine. Watch the burner while trying to dry clothes--the igniter should turn red, then the main valve should open to start the burner. If the plate turns red, but no fire, the control valve assembly may need to be replaced. Is the unit under warranty? If so, you may need to take advantage. Hope this helps!

Dryer start up fine then the gas turns off as ignitor continues


Hi Jim. Perhaps this will help you.

The burner assembly consists of the gas valve, the igniter and sensor, and the thermostats. The gas supplied to the appliance is turned on and off by the gas valve, as follows:


  • First--when you close the dryer door, set the timer, and press or turn the Start button--the motor starts. When it reaches full speed (in about a second) a switch on the motor turns on, which allows the electricity to flow through a simple thermostat to one side of the gas valve.

  • The gas valve then sends power to the igniter, which glows bright orange.

  • As heat and light from the igniter warm up a sensor that's right next to the igniter, the sensor circuit opens, then supplies power to the other side of the gas valve. This completes the circuit and opens the valve.

  • Once the valve opens, the gas rushes out and the igniter ignites it. As the gas burns, it keeps the sensor warm, which keeps the gas flowing.

  • When the dryer reaches the pre-set drying temperature, a simple thermostat turns off the flow of electricity to the gas valve and therefore turns off the gas.

  • When the temperature in the dryer falls about 20 to 30 degrees, the thermostat again allows the electricity to flow through to the gas valve, and the cycle starts over.

If you selected the Automatic setting, the cycle continues until the clothes are dry, then the timer advances and turns the dryer off.

If you selected a timed setting, the cycle continues until the time has expired, then the timer turns off the dryer

Dryer turns on and spins, but will not heat and dry clothes


Here is a quick course on the reasons why a gas dryer won't heat. If you are not mechanically inclined you will have to get a repair man because none of these reasons are quick fixes.

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.)
