GE Model DBXR463ED2WW TAKES A LONG TIME TO HEAT UP AND DRY CLOTHE

first things first. if any dryer regardless of brand takes 2-3 hours to dry cloths 90% of the time it is your exhaust duct. take the exhaust duct off the back of the dryer and dry some clothes if the clothes dry fast then you need to have your exhaust duct cleaned. either DIY or call a professional
if it still takes a long time to dry then it could be the thermostats or the thermistor.
but in my experience its normally the exhaust duct.

Hi,
Here is a tip that I wrote about dryers and noises...

This could be the clothes are coming out of the washer wetter than normal, or poor air flow. 80 min in a little long but a lot depends on the wetness and amount of clothes. If the vent system is clear then I would try smaller loads and checking the washer.

either the timer switch/control is defective or you have a broken or intermittant neutral wire and its backfeeding that open circuit to find another current path and this will trigger very strange operational issues

The exhaust hose or piping is clogged, try cleaning it or replace it.

no you can't

If you're experiencing a dryer that requires a longer time to dry, you may want to view this link:

Pay particular attention to the first major paragraph. I know the link is for a no heat problem, however, if you have a dryer that is starved for air, the heating circuits will eventually fail. In most cases, a no heat, or longer dry time problem is directly associated to clogged ventilation, kinked dryer vent hoses, improperly installed vent ducting, a clogged blower fan assembly, or rodents. Yes...the last one isn't always fun, but I have found bird nests, mice nests and even snakes inside dryer vents, clogging the air flow. The symptims were all the same - a dryer that would not dry properly. Before you assume you have a component going bad, take a good look at the way your dyrer is installed and inspect it thoroughly for what might be a good cleaning. The outsiode dryer vent should be at least 12 inches off the ground and a louver is recommended to cover the end to prevent critters from getting inside. In addtion, the SHORTER nd STRAIGHTER the dryer exhaust vent is, the better. If you have an exhaust vent with excessive bends, or excessive run length, this can contribute to poor heating of the dryer. Especially exhaust vents that run thorugh an attic or under a crawl space. They typcially develop sags, which create choke points where lint can accumulate to the point where it clogs. I do not know what your situation may be, but provide this as some helpful guidance just in case. I hope you find this information helpful. If you inspect your dyer and still have problems, please post back and let me know.

umplug your vent and run dryer see if that will make a different when dryer your clothe if not may be gas coils
