How a Tumble Dryer Works

1

2

3

Introduction

A tumble dryer uses heated air to dry loads of laundry. ① When the motor is started, the exhaust fan pulls

room temperature air in through the air intake at the rear of the tumble dryer and over the heat source (burner flame f or gas , heatin g elem ent for electric, and coil for steam).

② The heated air moves into the cylinder, where it is

circulated through the wet load by the tumbling action of the cylinder.

③ The ai r t hen passes through the lint filter, exha ust

fan, and is vented to the outdoors.

TMB2347S

Troubleshooting

To reduce the risk of electric shock, fire, explosion, serious injury or death:

• Disconnect electric power to the tumble dryer before servicing.

• Close gas shut-off valve to gas tumble dryer before servicing.

• Close steam valve to steam tumble dryer before servicing.

• Never start the tumble dryer with any guards/panels removed.

• Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the tumble dryer is properly grounded.

5. No Heat Condition (Non-CE and Non-Australian Models)

Ignition Control Module Function

There are four comp onents to the igni tion system : the module, the spark ignitor, the high voltage cable and ground wire. When 24 VAC is applied between the TH and GND terminals on the module, the module will send the high voltage signal to the igniter and 24 VAC to the gas valve coils. Gas will hit the sparking igniter and flame will be established. The igniter being engulfed in flame will create a millivolt electric signal that is sent back to the modu le by the hig h voltage cable; this is what th e mod ule sees as fl ame recogn ition . If the millivolt signal is not at the module in ten seconds, the module will go into safety lockout. The voltage will be cut from the igniter and gas valve coils and will not be stored until voltage is cycled at the module.

Intermittent Heat Test Procedure

On ignition control modules with date codes higher than 08t2, perform the following test.

Troubleshooting

Start the tumble dryer and run for 10 minutes (verify that the tumble dryer is heating properly). After the 10 minute cycle, re-start the tumble dryer and once again verify the unit is heating. Repeat this proc edure 3 tim es. If th e tumble dryer passes this test, the ignition control module is operating properly and SHOULD NOT be changed. Refer to SECTION 3 for additional service procedures.
