If you have no clue why your Samsung dryer dv42h5000ew/a3 isn’t heating, this piece of information will probably shed light on this issue. Before contacting a professional, implement several steps suggested by the manufacturer. Run a test using a timed cycle. To do this, set the dryer to Time Dry, make sure Eco Dry is turned off (if your model has it), and then start the cycle. After 30 seconds, open the door and feel inside. You'll be able to tell if the dryer has any hot air at all or if it's giving at least a little bit of heat. If it's giving at least a little bit of heat, the good news is you almost never need service. If the dryer has never heated since it was installed, review the installation. The following steps in the installation can cause no heat:
- Electric dryers require 240V outlets. If the outlet is not supplying enough voltage, the panel and motor may work, but the heater may not.
- For gas dryers, verify the gas line connection.
- For electric dryers, inspect the power cord installation.
- The exhaust vent must meet the dryer's requirements.
Cycle the circuit breaker. Turn the circuit off, wait 30 seconds, and then turn it back on. Electric dryers have two circuits. In most homes, these circuits are connected so that they will trip together. However, it is possible for only one of the circuits to trip. If this happens, the dryer will turn on and spin but will not heat. In case when the dryer refuses to heat despite all efforts, the heating element might be defective. Check to see resistance. Do not replace the heating element yourself, request service.
