Samsung dryer Mod DV328AEW/XAA electric 220v dryer tumbles but does not heat.I've checked and power is 220v (working) There appears to be no burnt wiring, inside. and heating coils appear to be intact.

HI. Ok, this unit is equipped with four thermostats that monitor the cycling information and the heater box for optimal operations. All of the thermostats should be tested for proper functions. I suspect that the culprit will be the thermostats mounted on the heater box, but test all to isolate.

Here are all the thermostats that are to be tested, below:

1. Thermal fuse - This will be mounted on the side of the heater box(chamber). Test properly to confirm its functions.
2. Cycling Thermostat - This will be mounted on the blower housing.
3. Cycling thermostat(2) - mounted on the blower housing
4. Hi-limit thermostat - Mounted next to the thermal fuse on the heater chamber/box.


Concerning the element:

You cant always tell by looking. This device must be tested to confirm that it is indeed working as designed. It should show some signs of continuity if it is indeed functioning.

Proper testing technique for most thermostats and fuses:

Label the wires and connections so that you can properly reconnect them later. The wires are connected with slip on connectors. Firmly pull the connectors off of the terminals. You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If either is corroded they should be cleaned or replaced.To test the thermostats or fuse, set the multimeter to the ohms setting X1. Touch one probe to each terminal. You should get a reading of either zero or infinity. At room temperature, the thermostats should have a reading of zero. When the thermostats are heated to their limit temperature, they should switch off and you should get a reading of infinity. The fuse should be tested at room temperature for continuity.
