What has been the main issue with the Samsung DV42H5000EW not heating anymore?? I've had one a couple of years and all of a sudden it quit heating/drying clothes. We replaced the 2 thermostats and it's still not heating. Should I replace the heating element, or thermistor or just sell it and buy a different brand that will last more than a couple of years??
Does the unit have no heat at all or not enough heat?
Check how much heat the dryer gives.
Clean the moisture sensors.
This type of issue will need to be addressed by having the unit serviced. If the unit is in/out of warranty you can use the following link to find a list of service centers near you that can do the repair: http://www.samsung.com/us/support/service/location.
