Gisele, a couple of things you can look at. I am making the assumption that you have a multimeter, or at least have access to somebody who does and that you have a few basic hand tools. First things first ;-) check to make sure that your dryer vent is not blocked, crimped or otherwise obstructed. Then try flipping the breaker off/on slowly a couple times. Sometimes you can loose half the line without actually tripping the breaker.

Check the voltage at the plug L1 to L2 should be 240 volts. L1 to Neutral and L2 to Neutral, both should be 120 volts. If that is okay unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out

Be careful as exposure to 240 volts is a hair raising experience and can be lethal.

If that checks out okay, unplug your dryer and remove the back of the dryer and check the heating element. You can check the heating element with a ohm meter or by removing it and looking to see if the element has a broken wire inside.

HEATER

1. Disconnect the electrical power to the dryer.

2. Set the ohmmeter to the R X 1 scale.

3. Disconnect one of the wire connectors from the heater terminal block.

4. Touch the ohmmeter test leads to the terminals on the heater terminal block. The

ohmmeter should indicate between 7 and 12 ohms.

THERMAL FUSE

Electric Dryers: The thermal fuse is wired in series with the drive motor. If the thermal fuse opens, 91°C (196°F), power to the motor is turned off. A centrifugal switch on the motor also opens the heater circuit. Gas Dryers: The thermal fuse is wired in series with the gas valve. If the thermal fuse opens, 91°C (196°F), power to the valve is turned off. A centrifugal switch on the motor also opens the heater circuit. Once the thermal fuse has opened, it will not reset, and must be replaced. Check for a failed thermistor, or a shorted heater element (electric dryers only).

1. Disconnect the electrical power to the dryer.

2. Set the ohmmeter to the R X 1 scale.

3. Disconnect the wires from the thermal fuse.

4. Touch the ohmmeter test leads to the thermal fuse terminals. The ohmmeter should

indicate continuity (0 Ω). If the meter indicates an open circuit (infinite), replace the thermal fuse.

THERMAL CUTOFF

(ELECTRIC DRYERS ONLY)

The thermal cutoff is a non-resettable device. The cutoff temperature is 178°C (352°F). If the dryer does not heat and there is 240 VAC to the dryer, perform the following test.

1. Disconnect the electrical power to the dryer.

2. Set the ohmmeter to the R X 1 scale.

3. Disconnect the wires from the thermal cutoff.

4. Touch the ohmmeter test leads to the thermal cutoff terminals. The ohmmeter should indicate continuity (0 Ω). If the meter indicates an open circuit (infinite), replace both the thermal cutoff and the high-limit thermostat. In addition, check for a failed heater element, or a blocked, or improper exhaust system.
