The Ultimate Dryers Quiz
by Staff
Clothes dryers are found in almost all homes. They are a reliable and relatively inexpensive appliance, and will get your laundry clean on a rainy day. Take this quiz and see how they work.

Just how complicated is the average clothes dryer?

  • It is an extremely complex appliance.
  • Depends where it's made.
  • It is a simple appliance

What is common to all clothes dryers?

  • All have a tumbler, heater and exhaust vent.
  • All have a heating system and a separate container for delicate items.
  • All gas powered dryers are top-loading.

Where does the air enter the dryer?

  • via the exhaust vent
  • through openings in front of the dryer
  • no air enters, except for the air in the clothes

After the air enters the dryer, where does it go?

  • The air is drawn into the tumbler where it is heated.
  • The air is first filtered by a lint screen then goes past the heater into the tumbler.
  • The air is heated by the heating element and then moves to the tumbler.

What do you think is the purpose of the lint screen?

  • The lint screen is made to remove lint from the clothes.
  • The lint screen prevents lint from reaching the heating element where it could catch fire.
  • It will prevent the exhaust fan from getting clogged with lint.

After a trip through the lint screen, what is the destination of the air?

  • back into the tumbler for a second round of drying
  • the exhaust pipe via the fan
  • the motor, to cool it

How much power does the heating element of most dryers consume?

  • 2,500 to 3,500 watts
  • 4,000 to 6,000 watts
  • more than 6,000 watts

How does the fan work?

  • The spinning motion causes a partial vacuum causing the air to rise through the exhaust pipe.
  • The fan removes impurities from the air, which becomes lighter enabling it to rise out of the dryer.
  • It pulls air from the tumbler and forces it out through the exhaust pipe.

How complex is the gear system of the dryer?

  • It is a belt drive without gears.
  • The higher power dryers have a complex gear system to gain maximum revolutions per minute.
  • The smaller dryers need a gear system to make them more efficient.

From what you know about motor-driven appliances, what do you think is the weakest link in most dryers.

  • motor
  • fan
  • belt

What is it that most tumblers lack?

  • thermostats
  • bearings
  • rustproof interiors

What is the purpose of a cycle switch?

  • controls speed of tumbler
  • controls fan
  • controls heating elements

If you push one of the control buttons while another is depressed, what happens?

  • You'll have two depressed buttons.
  • Depressed button will pop up.
  • You could short-circuit the system.

Does the dryer have a safety system?

  • There are temperature shut-off switches.
  • A thermometer in the tumbler monitors the temperature.
  • The micro-circuit in the cycle switch measures power-consumption.

What happens if airflow is cut off and the first sensor has no air on it to monitor for overheating?

  • The control panel thermometer will detect an anomaly and switch off the dryer.
  • If the fan doesn't work an automatic circuit-breaker kicks in.
  • The heating element sensor will detect overheating and shut off the power.
