What is true of this model and changes how you fix it
- Fuel — confirm ELECTRIC or GASThis entry series came in electric (DV42H5000EW) and gas (DV42H5000GW) — check the suffix. Electric no-heat = element/240V half-breaker/thermal fuse; gas no-heat = igniter/valve coils/flame sensor/gas supply.
- VentingA vented dryer — clogged lint screen or blocked duct causes long drying and overheating. Clean both regularly.
- Feature tierAn older entry Samsung dryer with Sensor Dry; typically no Wi-Fi, so a long cycle is airflow or a mixed load, not a smart feature.
- Electric no-heatAn electric dryer that turns but does not heat has a tripped half of the double breaker, a failed heating element or an open thermal fuse. Reset both halves of the breaker first.
- Gas no-heatA gas dryer that does not heat has a failed igniter, valve coils, flame sensor or gas supply. It is not a breaker problem, and a gas fault belongs with a qualified technician.
- Airflow firstOn any vented dryer a clogged lint screen or a blocked duct causes long drying and overheating. Clean both before you suspect a part.
- An older, simple dryerWith no Wi-Fi, a long cycle is airflow or a mixed load, not a smart feature adjusting. Sensor Dry ends when the load reads dry.
- The thermal fuseA thermal fuse opens when the dryer overheats, often from a blocked vent, and cuts heat. Replacing it without clearing the vent only repeats the failure.
- Finding the model numberThe label is inside the door opening and shows DV42H5000 with the suffix and the serial number.
- A simple, older dryerWith no Wi-Fi or app, the controls are a dial and buttons. A cycle that stops early is usually the sensor ending the cycle on a damp-reading load, so a mixed load of towels and light fabrics can fool it.
- Where the thermal parts sitThe thermal fuse and the thermostats are on the heater housing or the blower housing, behind the rear or the front panel. Testing them needs the dryer unplugged and a meter; replacing a part without clearing the vent only repeats the fault.

Exact questions
Questions that only have an answer for the Samsung DV42H5000 dryer
My older Samsung DV42H5000 isn't drying well.+
Start with airflow regardless of fuel: clean the lint screen every load and clear the exhaust duct — a blocked vent is the top cause of poor drying on any vented dryer. If there is no heat at all, check whether yours is electric or gas: electric points to a half-tripped 240V breaker or the element, gas to the igniter and valve. Cleaning the moisture-sensor bars also helps if Sensor Dry is ending cycles early.
