It takes 2 or 3 cycles, even for small cycles to dry. The heating element seems to cut off after a few minutes, I checked the duct and it does get hot, what do you think is wrong with it?
Answer Hello Robert. It sounds like the venting system is clogged or kinked. You will need to check the vent and clean it out. Be sure and clean the vent pipe and the dryer air duct assembly. If the air flow is not good, the unit will retain moist air causing the clothes not to dry. Try running the unit with the vent unhooked from the back of the dryer and see if the dryer works properly.
I thought the heating element was bad but I removed it and put power to it and they heated up fine. Is there another part or parts that could be causing the heating element not to get hot?
Answer Hello David. Check and make sure you have 240 volts coming to the dryer. Check and make sure the unit is not set to Air Fluff. Also check the heater and thermostats and see if they are good. You can test these with a multi-meter TJMA-DM1. They should read closed for continuity. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
My renter says that they now have to go through 2 drying runs to get the clothes dry. That would seem to indicate that a heater element is bad and that the unit has two heater elements. They said that the dryer is still producing heat. Can the heater tray be removed from the back of the washer/dryer unit.
Answer Hello Clint,
This is most likely not a dryer problem. Think about it like this, the heat doesn't dry the clothes. If it did, you could put the wet clothes in the microwave to dry them. The heat from the dryer helps to evaporate the moisture so the air flow can more easily carry the moisture away. Thinking like this, the longer, more complicated (un-necessary elbows and turns), and the more restricted the duct is, the longer the clothes will take to dry, the more wear and tear on the dryer (the sooner it will give problems since it's being worn out to dry one load), and the higher the electric bill will be. So you can see why technicians place such high emphasis on the importance of the dryer exhaust duct. Many times I have entered a customers' home and showed them the flex duct smashed flat behind the unit and didn't even have to work on the dryer. Correcting the duct eliminates the customers' complaint.
Another point I need to make is that when the exhaust cannot escape the dryer cabinet since the restricted duct caused the heat, lint, and moisture to blow past the felt dryer drum seals, this heat that is blown back into the cabinet will cause the thermostats to open. This is about the time the customer will check on the clothes and they think it isn't heating. Most of the time, if the ducting is corrected before a component in the unit fails, the dryer will not require servicing at all.
To answer the last question, the heating element cannot be serviced from the rear. The dryer will require a complete tear down to access the heating element.
