All dryers need three things to work.

  • Heat
  • Tumbling
  • Airflow

No Heat

The electrical requirements for most electric dryers is 240 volts. There could be 120 volts missing. A possible fix for this is to throw the breaker for the dryer all the way off, then back on again. Then test the dryer. If the electrical is ok, the heating element, thermal cut off, thermostat, or terminal block could be bad. In rare cases the timer or motor could cause a dryer not to heat.

Won’t Tumble

The most common cause for a dryer not to tumble is a broken belt. If the belt is broken, it is necessary to check the tension pulley for abnormalities. If the tension pulley is bad, a newly installed belt will not last.

Dryer Not Working at All

Check the breaker first then check the lid switch. If the lid switch is broken, the dryer will not operate. The other possibility is the thermal fuse or the terminal block. Unplug the dryer and make sure the plug terminals are good as well.

Heats But Not Drying

Make sure that the dryer is tumbling. If it is, then remove the vent hose from the back of the dryer. Turn the dryer on and test for good airflow from the back. It should be as powerful as a hair dryer on low setting. If the dryer is producing a good airflow, the vent ducts in the house might be clogged. This will keep the dryer from drying.

Dryer Repair and Maintenance

Overheats

This is usually caused by an internal build up of lint or a blocked vent hose. The vent hose can also be smashed behind the dryer. If the dryer can’t blow enough air through the heater coils, the dryer will overheat. If it gets too hot, the terminal protectors could engage disabling the dryer.

Dryer Odor

It is rare that a dryer, electric or gas, will malfunction and cause an internal odor. Odors usually come from external sources such as an old rag with turpentine or possibly lint that fell on the heating element.

No heat gas dryer

There is a thermal fuse, gas coils, flame sensor, and gas valve coils that can cause no heat problems.
