Most common repairs needed to fix a Samsung dryer
Heating Element Replacement
An open heating element could be causing the problem when your dryer has no heat. “Open” means that the heating element is broken and current isn’t flowing through the element to produce heat. You may not see physical damage on the heating element for it to be electrically open. An interior break in the continuity of the element can prevent it from heating. When your dryer isn’t heating, have a Sears Home Services Technician visit your home and fix the dryer.
Thermal Cut-off Fuse Replacement
A failed thermal cut-off fuse will prevent your dryer from heating. This fuse is a safety device that helps keep the dryer from overheating. Overheating is often caused by a clogged exhaust vent system in the dryer. Once the thermal cut-off fuse trips, it won’t reset. You’ll need to have a Sears Home Services Technician visit your home and replace the blown thermal cut-off fuse. The technician will check for the cause of the blown fuse and correct any additional problems so the dryer will heat and run properly after replacing the fuse.
Thermal Fuse Replacement
In a gas dryer that isn't heating, a blown thermal fuse could be causing the problem. The thermal fuse is a safety device attached to the blower housing that trips when the dryer overheats. A faulty thermal fuse may trip at a lower temperature than it is designed to trip at. When your gas dryer won’t heat, schedule a repair appointment through Sears Home Services and we’ll send an in-home technician to fix the dryer. The technician will check the thermal fuse and replace it if it’s blown.
Why is my Samsung dryer running but not heating?
Gas Dryer Heating Failure
When you find the air in your dryer not heating up, the culprit could be:
- Gas supply problems.
- Failed timer or electronic control board that controls the heat.
- Bad heater relay.
- Blown thermal cut-off fuse.
- Faulty thermistor.
- Broken operating thermostat.
- Failed high-limit thermostat.
In many gas dryers, a blown thermal fuse will prevent the burner from working.
Additional failures in a gas dryer not heating up could be bad gas valve coils, a failed igniter or a faulty flame sensor.

What to expect when you experience a Samsung dryer no heat issue
How is the no heat problem fixed?
Correcting most no heat problems usually involves replacing the heating element, thermal cut-off fuse or thermal fuse. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.
Sears Home Services recommendations for a dryer that won't heat
When the dryer has no heat it can be for many reasons. To avoid replacing unneeded parts we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. We provide Samsung dryer repair near you, and our technicians are experienced at diagnosing and fixing all types of dryer issues.
What to look out for with a dryer no heat diagnosis
Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your dryer problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.
Samsung DV42H5200EW/A3 Not Heating
When your find your Samsung DV42H5200EW/A3 not heating, start by resetting the house circuit breakers for the dryer. The drive motor will run and spin the dryer if only 1 leg of 240-volt power is supplied to the dryer. If the second leg of power is interrupted by a tripped circuit breaker, the dryer won’t heat. Reset both circuit breakers because it’s hard to tell whether a breaker has tripped.
If your Samsung DV42H5200EW/A3 is not heating after resetting the house circuit breakers, check the power cord to make sure it’s fully plugged into the electrical outlet. Plug in the power cord fully if you find it partially pulled out.
Check the power cord for damage and replace the power cord if it’s cut or crushed.
Reset the electronic control board in your Samsung DV42H5200EW/A3 dryer if the above tips don’t help you restore heating. To reset the control board, turn the dryer off and unplug the power cord from the electrical outlet to completely disconnect electrical power from the dryer. Leave the power cord unplugged for 2 minutes and then plug it back in to restore power. The electronic control board will reboot and the dryer may heat. If not, schedule dryer repair service and we’ll send a Sears Home Services technician to your home to fix the heating failure.
Samsung DV42H5000EW/A3 Not Heating
If your Samsung DV42H5000EW/A3 is not heating and the cycle ends quickly, a problem with the moisture sensor could be causing the problem. The moisture sensor bars attached to the lint screen housing inside the drum detect wetness in the clothes. If the bars are coated with lint and other deposits, the moisture sensor will detect that clothes are dry. The control will shut off heat and end the cycle even though clothes are still wet.
If this describes the scenario you are seeing with your Samsung DV42H5000EW/A3 not heating, check the moisture sensor bars. Clean the moisture sensor bars using rubbing alcohol and a lint-free cloth. Test the dryer to see if it heats and dries the clothes properly after cleaning the moisture sensor bars.
If the dryer doesn’t heat after cleaning the moisture sensor bars, reset the house circuit breakers for the dryer to ensure the machine is getting 240-volt power.
If the dryer still won’t heat after resetting the house circuit breakers, a broken heating element, bad electronic control board or a number of other failures could be preventing the dryer from heating. Schedule dryer repair service and we’ll send a Sears Home Services technician to your home to fix the heating failure.
Samsung DVE50M7450W/A3 Not Heating
A Samsung DVE50M7450W/A3 not heating could have one of these failures:
- Lack of 240-volt power. Reset the house circuit breakers to restore proper power to the dryer.
- Broken heating element. Have a service technician check this internal failure.
- Defective electronic control board. Schedule dryer repair service to have a Sears Home Services technician check the control board and replace it if necessary.
- Clogged venting. Clean the flexible exhaust vent hose behind the dryer. Clear lint and debris from the exhaust vent duct system going to the outside of your home. Have a dryer duct cleaning service clean the exhaust vent system if you aren’t able to clean the duct system yourself.
- Check the moisture sensor bars. Clean lint and dryer sheet residue from the sensor bars using rubbing alcohol and a lint-free cloth so the sensor will accurately sense wetness in clothes and won’t stop heating and end the cycle early.
Samsung DV42H5200EP/A3 Not Heating
Checking the house circuit breakers is the first step in dryer troubleshooting for a Samsung DV42H5200EP/A3 not heating.
The dryer motor will run and spin the drum if only the L1 leg of 240-volt power is making it through the circuit breaker to the dryer. If the second breaker controlling the L2 leg of 240-volt power is interrupted by a tripped circuit breaker, the dryer won’t heat.
It’s often difficult to tell when a breaker is tripped so reset both circuit breakers. If your Samsung DV42H5200EP/A3 is not heating after resetting the circuit breakers, one of these failures could be causing the problem:
- Broken heating element.
- Bad electronic control board.
- Faulty high-limit safety thermostat.
- Defective thermistor (temperature sensor).
- Broken motor centrifugal switch.
- Wiring failure.
Schedule dryer repair service to have a Sears Home Services technician visit your home and check these issues.
DV45H7000EW/A2 Not Heating
When your Samsung dryer DV45H7000EW/A2 is not heating, reset the house circuit breakers for the dryer in case one of the breakers tripped. Resetting the circuit breakers may restore heating in the dryer.
If not, reset the electronic control board by following this procedure.
- Turn off the dryer.
- Unplug the dryer power cord.
- Leave the power cord unplugged for 2 minutes.
- Plug the dryer power cord back in to restore electrical power to the dryer.
The control board will reboot and the dryer may operate and heat properly after resetting the circuit board.
If your Samsung dryer DV45H7000EW/A2 is not heating after resetting the control board, a broken heating element, defective electronic control board, bad thermistor (temperature sensor), blown thermal cut-off fuse or a number of other failures could be preventing the dryer from heating. Schedule dryer repair service and we’ll send a Sears Home Services technician to your home to fix the problem.
DV42H5000EW/A3 Not Heating
When your Samsung dryer model DV42H5000EW/A3 is not heating, reset the house circuit breakers in case one of these breakers is tripped. This may restore heating to the dryer.
If the dryer heats briefly at the start of the cycle then quits heating, check the moisture sensor bars to see if they’re coated with lint and deposits from dryer sheets. If the moisture sensor bars are coated in this manner, the bars won’t be able to sense wetness in the clothes. The control will shut off the heating element and run the dryer for a while with no heat. The clothes will still be wet and won’t feel hot after the dryer stops.
If you find the sensor bars coated with lint and deposits, clean the bars using rubbing alcohol and a lint-free cloth. The dryer may heat and operate properly to dry the clothes after cleaning the moisture sensor bars.
If not, schedule dryer repair service and we’ll send a service technician to your home to fix the heating failure.
A Samsung dryer cycling with no heat typically indicates a failed heating element or gas ignition. Multiple spins only hike utility bills. Instead, consult dryer repair near me for a targeted fix. Once heat returns, clothes dry more rapidly and fully.
