How Your Dryer Works

Lint

Filter

Section 2 Introduction

Cylinder

Heater

Duct

The dryer uses heated air to dry loads of laundry. When the motor is started, the exhaust fan pulls room temperature air in through louvers at the rear of the dryer and over the heat source (burner flame for gas and heating element for electric). The heated air moves through the heater duct and into the cylinder, where it circulates through the wet load. The air then passes through the lint filter, air duct, and exhaust fan, where it is vented to the outdoors.

light will flash a “Flash Code” when the control is in the lock-out mode. The light will flash on for 1/4 second then off for 1/4 second for each number. The pause between flash codes is 2 seconds. These flashes are caused by the control’s diagnostic test and can be interpreted by reading the following:

POSSIBLE CAUSE

Internal failure.

Air in gas line.

• Purge air from gas line.

Sensor coated with Aluminum Oxide.

• Wipe sensor clean or replace sensor if necessary.

Incorrect gas pressure.

Gas shut-off valve closed.

Internal failure.

TO CORRECT

• Reset dryer. (Refer to NOTE above.) If condition persists, then replace control.

• Check for correct gas pressure. If gas pressure is incorrect, then contact local gas company.

• Open gas shut-off valve.

• Reset dryer. If condition persists, then replace control.

Loose or disconnected wiring.

Open Igniter/igniter sensing circuit/ voltage measurement circuit.


• Check all wiring leading to, or coming from, the control module for secure connections.

• Check igniter and all circuits, replace if necessary.


• Check gas valve and replace if necessary.

Inoperative gas valve.

Inoperative sensor.


Incorrect wiring.

Incorrect polarity.

• Replace sensor/igniter.


• Check wiring diagram and make sure dryer is wired correctly.

• Contact a professional electrician to check the polarity, and correct any problems.

19. LEVELING LEGS


NOTE: Dryer should be installed on a solid and level floor.

a. Place dryer in position, adjusting the legs until dryer is level.

WARNING

W001R1

NOTE: Legs can be adjusted outside the dryer by using a 1-1/4 inch size wrench, or from inside the dryer (with lower front access panel removed) by using a 1/4 inch drive ratchet with extension.

b. Keep dryer as close to the floor as possible. All four legs must rest firmly on the floor so weight of the dryer is evenly distributed. The dryer

MUST NOT rock.

IMPORTANT: DO NOT move the dryer at any time unless the dryer is completely assembled. DO NOT slide the dryer across the floor once the leveling legs have been extended as the legs and base could become damaged.

To reduce the risk of serious injury or death by carbon monoxide and other gases in gas dryers, carefully read and follow all instructions given in this section.

25. BURNER SYSTEM OPERATION

(Gas Models – Refer to Figure 8.)

a. Components

This burner has four basic components: a silicon carbide (glow bar) igniter, burner tube, sensor, and a two-stage gas valve consisting of a split-coil valve and a secondary coil valve.

The split-coil valve is opened when the dryer thermostat calls for heat, while the secondary valve does not open until the igniter has attained ignition temperature.

b. Pre-Ignition Circuits

When the dryer thermostat calls for heat, circuits are completed through the holding coil, sensor, booster coil and igniter. Both coils must be energized to open the split-coil valve. Once opened, the holding coil can hold the valve open without assistance from the booster coil.

The sensor triggers the current to travel around the secondary coil and through the igniter, causing the igniter to get hot.

c. Burner Circuit

In approximately 30 seconds, the igniter attains ignition temperature and ignition is made. The heat from the burner flame causes the sensor contacts (located on burner housing beside the igniter) to open. A circuit is then completed through the secondary valve coil, opening the valve and allowing gas to flow.

d. Momentary Power Interruption

Upon resumption of power, sensor contacts will still be open, permitting secondary valve to open. However, with the secondary coil in the circuit, the booster coil cannot draw enough current to open the split-coil valve. When sensor contacts do reclose, the secondary valve will close, and the burner system will be in the normal pre-ignition circuit.

e. Flame Failure

In case of flame failure, the sensor contacts will re-close in about 45 seconds. This will close the secondary valve and the burner system will be in the normal pre-ignition circuit.

f. Ignition Failure

If flame is not established as sensor contacts open, secondary valve will remain open until sensor contacts re-close. Sensor will continue to recycle the igniter and secondary valve (about once per minute) until ignition is made or dryer is turned off.
