I have a Kenmore Model 417.90862990. Gas Dryer wont heat. Does not glow. How should I trouble shoot the issue

SOURCE: kenmore gas dryer wont heat, model #11074832400

check the igniter,thermal fuse,operating themastat there is a small plastic piece on the lower left hand corner pop that out and when you turn your dryer on it should be glowing red if not its the igniter

i am sending you all the possibilities for your problem, check either of these causes ----and than let me know if it is solved----

Power from the house
Check to see whether there's power getting to the dryer. Is it plugged in? Check for blown fuses or tripped circuit breakers--your dryer uses two fuses or circuit breakers. The dryer could tumble but not heat if only one of the two fuses is blown. If you have circuit breakers, one of the two circuit breakers can trip, even if the two for the dryer are connected.


Heating element
Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable.


Thermal fuse
On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.)


Wiring
A common problem is for the main wiring connection from the house, at the dryer, to burn and break its connection. Because the dryer can still tumble with partial power, the connection may be only partially defective. You may need to replace both the power cord to the dryer and the terminal block inside the dryer that the wire is attached to.

does the dryer heat initially when you first turn on the dryer Or no heat at all?

the first thing i would check is tthe thermal fuse thats located on the back of the unit. test it with a multimeter and see if it has continuity, if it doesnt then replace that and your operating thermostat. the check to be sure you venting to the outside of your house is not clogged

Since your hot surface ignitor is glowing, that means it is trying to heat, or that all the temp. switches are good and the timer is sending the signal. First check that there is actually gas pressure to the dryer. But the common problem is the coils on the gas valve. There are two, called the booster/holding coil, and the secondary coil. They are purchased as a set (part #279834 / $20.00) if it is the same as my mdg8600aww model. If that doesn't work, then likely the gas valve itself.

Sometimes those coils will open circuit when they warm up, and close when they cool down, giving you an erratic operation symptom.

Check the following areas to combat this issue. the most common problem spot will be a blown Thermal fuse.


1. Gas valve coils
Igniter glows, then shuts off without igniting gas - the problem is probably with defective coils (black, located on top of the gas valve). It is recommended to replace all coils (usually two or three) if found defective.

Note: Sometimes the whole gas valve may be defective, thus not letting the gas out. However, this problem is not common.

2. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse.

3. Igniter
Igniter may burn out or break. Replace the igniter if found defective.

Note: Igniters are very fragile and break easily. It is recommended to handle the igniter only touching the ceramic part of it (usually white in color).

4. Flame sensor (or radiant heat sensor)
Replace the sensor (located near the igniter) if found defective.
