Dryer no heat blows cold air what s a common fix gas dryer

SOURCE: Whirlpool 29"gas dryer Model#LGN2000LW1

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.

SOURCE: electric dryer only blows cold air......no heat

Your problem is associated with the heater element and or thermostats, you need to access these in order to determine the prob.
You have to lift the top cover and remove the front panel to do this.
Depending on your model of dryer, there are at least 2 ways to get into the dryer

It would take too long to fully explain the different ways to get into the dryer,so try this site which should give you all the info you need.
partselect.com

then click on free repair help then click on dryers, and then on my dryer will not heat up.

I would be grateful if you could let me know if you find the info you wanted from this site.
plz rate my solution.
Thanks.

SOURCE: Gas Dryer does not continue to heat.

Check the Following to address this issue--



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.

SOURCE: gas dryer wont heat up, blows only cold air.what would cause this

Could be a bad hi limit thermostat. Could be a bad glowbar ignitor. Check the glowbar ignitor at the gas valve, is it glowing bright orange/red? If not. Replace the ignitor.
