The dryer does not heat. We had someone out and he said the heat sensor was tripping because the dryer was overheating. He recommended that we have the duct cleaned out, which is was then and has been...

It is possible the over temp snap switch could be bad, but also they were in the right direction with an air flow problem too. The duct needs not to be restricted, and you must verify the blower fan is in good condition, turning, and also free of debris.

DBV512gfoww dryer does not dry clothes completly on auto cycle. I have replaced both gas coils.

If the dryer is heating up, and clothes are being partially dried, then your dryer may be overheating. Check the ducts for lint balls / clogs, pay attention to the exterior opening, as well as the duct tube on the back of th e dryer itself. If everything appears normal / clear, you may have a limit switch that is acting up.

If the dryer is not heating up, then likely air movement (through ducts) is not high / fast enough to trigger that indicates that air flow is okay. Check all the duct work. If clear, then sensor / vane switch for air movement may not be closing like it should, which won't allow the igniter / gas valves to function.

Heating element does not stay on long enough....replaced both thermostats on air duct already. maybe sensors and element bad?

Check your duct and outside vent! If it's blocked, your heating element will work only intermittently...

Took back off of whirlpool electric dryer to find where heating element is ocated,, where is it and what do i need to know from there to replace it ???? thank you

Depending on the model. The heating element is inside a piece of ductwork usually in the lower right hand corner of the back of the dryer.

You usually start by taking off the back cover *(which you did) and then you look for a section of round ductwork that has a couple sensors attached as well as wires going down to the bottom where the air enters the duct. The heating element is inside this piece of ductwork.

You need to takes the leads off the two sensors and the heating element first. Then you can remove the duct mounting bracket screw *(this one might need to be reached from the top of the dryer) and then you can slide the heater/duct section off the dryer and look inside to see your heating element. Just look at the element from one end to the other to check for breaks. Order a new element either from your local appliance parts store or get it off of Ebay. They usually are cheap and only take a day or two to arrive by mail.

Good luck and be careful. Always unplug your appliances before attempting any kind of work inside!

Dryer wont heat

Check to make sure you are getting full 220 Volt power to the dryer, if you are then:
Sounds like your problem may be with the heating coil.
Remove the back of the machine and try to locate the air duct going from the blower to the drum. Normally inside the air duct you will find the heating coil and the thermostats/thermistor.
Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if not you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor by removing the two wires and taping them together with electrical tape.
If the coil heats up then replace the thermostat/thermistor.
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST. This could cause a fire, as you have removed the safety of overheat from the machine.
I will include these two websites for parts and further help:
Both also have chat assistance 24/7.
Good Luck,
Hope this helps

Hi, i have a homebrand dryer. Model: TD50-89S. Without asking first,my son transferred washing to dryer. Unfortunately, there was alot of white fluff all over washing and he assumed the dryer could take...

Your duct work is probably clogged with the fluff, which will not allow the air to flow though like it should. When that happens, the heat builds up on the cabinet and the heat sensor shuts down the heat. Its an easy fix, it this is the case. Just remove the duct from the dryer, clean it out, clean out the fluff from the dryer duct connection, then go outside and inspect the outside dryer vent for clogs. Make sure the flapper is working on the outside vent as well. Good luck!

Dryer heats once or twice then stops heating

It's likely one of the coils is opening a break in the coil as the coil heats up. This coil will shrink when cool and be able to run again. The number for the coil kit, which will replace ALL the coils, for your machine is 12001348.

Disconnect power and turn off gas before working on this dryer. Working on gas dryers is not recommended for people who are not professionals.

Service on gas appliances should be undertaken by professionals only due to the danger of gas leakage which can cause fires or death by asphyxiation.

The disassembly procedure is covered beginning on page 3-10 of the manual listed at the link below. Operation and replacement of coils is covered at page 3-32. Replace All coils with Kit Number listed above. Take care not to touch or hit the ignitor or you will be replacing it also. It is VERY brittle.

Reverse process to re-assemble. Good Luck

Clothes Dryers

no, there is 2 sensors in the duct work that will shut down the heating element when the temp gets to a certain point. there may be a "punch out" in the side, but this is not for air to get out. the internal ducts in a dryer are sealed.
