Whirlpool lgq9858pw1 will not heat

SOURCE: Whirlpool Estate Dryer TGDS840JQ1 dryer runs but

when you say heat up is it at least getting warm...
you may have a igniter gone bad or your thermostat may have failed... your igniter is what has to ignite the gas to burn to make it hot. If its electric then your heating coil has failed and needs to be replaced

Check the following to address this issue.




1. No power to the dryer
Make sure there's power getting to the dryer. Check for tripped circuit breakers or blown fuses. An electric dryer uses two circuit breakers or fuses, and if only one of two is tripped or blown, the dryer might still run but not heat. Sometimes the power cord disconnects or burns at the dryer, if this is the case, the wiring and the terminal block must be repaired or replaced.

2. Heating element
A burned out heating element will show no continuity when measured with a meter. Replace the element if found defective.

3. 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....

SOURCE: Whirlpool Duet dryer not drying like it used to

If your duet isn't heating properly and you have taken care of the lint problem then you could have one of two problems. Either you have a bad heating element or you have a bad fuse or temperature sensor.
If your dryer is not heating at all then it is most likely the fuse or temp sensor. If it is heating and just not enough it is probably a bad heating element.
Both problems would require a repairman to come and fix normally, however if you believe it is the heating element that can usually be replaced by the homeowner without too much trouble. Just make sure to ask where it is located from whatever place you but the new element from.
