Glo-Bar Igniter Circuit Operation

The glo-bar igniter circuit is made up of the following components: a gas valve with safety and main valve s, a glo -bar ign iter , and a flame detector . The safety valve is actuated by a double coil, that comprises a safety coil (resistance approximately 1400 ohms) and a booster coil (resistance approximately 580 ohms). Both coils are needed to open the safety valve. Once energized, the safety coil alone will hold the valve open. The main valve has a single coil (resistance approximately 1300 ohms).

The flame detector (< 1 ohm) is mounted on the combustion chamber . It is normally in the closed position (N.C.). The flame detector is opened by the radiant heat produced by the glo-bar; and once open, the flame detector will be held open by the radiant heat produced by the gas flame.

When the control system calls for heat, the following circuits are energized:

1. N- through detector, igniter , outlet control backup, inlet safety thermostats to L1.

2. N- through detector, booster coil, outlet control backup, inlet safety thermostats to L1.

3. N- through safety coil and outlet control backup, inlet safety thermostats to L1. When the glo-bar is heating, the booster and safety coils are both energized and will open the safety

valve. The main valve is closed as its coil is bypassed by the N.C. flame detector . When the glo-bar reaches ignition temperature, approximately 60 seconds or less, the flame detector is heated and opens, which places the main coil in series with the glo-bar . The main valve opens, allowing gas to flow into the combustion chamber and ignite.

The main coil, now in series with the glo-bar , causes the glo-bar to cool down. However , the flame detector is held open by the radiant heat from the gas flame. The booster coil is now also in series with the main coil and is essentially inoperative. Should a momentary power failure occur , the gas valve will shut off and an attempt to restart will not occur until the flame detector cools and resets, approximately 30 seconds.

3. Remove 1 screw and the thermistor .

Inlet Safety Thermostat

An inlet safety thermostat is located on the left side of the heater housing on electric dryer models, and on the right side of the housing on gas dryer models. The electric model has an L210-30 °F rating and the gas model has an L300-40 °F rating. The inlet thermostat is wired in series with the outlet control thermostat. If the thermostat reaches 210 °F on electric models or 300 °F on gas models, it will open the L1 side of the heater or gas valve circuit, interrupting heater or gas valve operation. The thermostat will close when it has cooled to 180 °F on electric models and 260 °F on gas models, restoring heater operation.

Sensor Rod Circuit

The moisture-sensing rods are part of a circuit that is designed to utilize a low-voltage capacitor that charges to 5 VDC when the circuit is open and discharges to 1 VDC when the circuit is shorted. A space between the 2 rods causes an open in the sensor rod circuit. When wet clothes touch the two rods, they create a short, which discharges the capacitor. When the clothes become dry , they cannot short the circuit; and the charge across the capacitor builds to 5 VDC. If the electronic control board reads 1 VDC across the capacitor , it is determined that the clothes are wet. As the clothes are dried, the voltage across the capacitor increases. When the electronic control board reads 5 VDC across the capacitor , it is determined that the clothes are completely dry . The capacitor for the sensor rod circuit is in the wire harness near the sensor rods and can be replaced as a separate component.

Sensor

Rods

Note:

• Proper leveling of the dryer is vital for accurate sensor drying. Excessive rearward adjustment will cause clothes to tumble toward the rear of the drum, preventing contact with the senor rods, thus producing a false dryness reading.

• During sensor drying, if the sensor rods are not shorted within the first 6 minutes of the cycle, the unit will determine that the drum is empty and terminate the drying cycle.

The dryer will signal when the clothes are at 17% moisture level if equipped with a damp signal that has been selected.

Approximate values for dryness level: Damp = 1 7 %

Less dry = 10 % Dry = 2-6% More dry = <2%

– 27 –

Page 30

To test the sensor rod circuit: Place the dryer in service mode and index to the rod voltage test. The rod voltage, in hundredths of a

volt, shall be displayed on the DSSD. Open the door and touch the rods with your hands and view the DSSD. The voltage displayed on the DSSD should diminish, indicating that the capacitor is discharging properly . No change on the DSSD indicates that either the rods are not connected to the board, an open exists in the sensor rod circuit, or there is some other problem on the board. When the rods are released, the voltage displayed on the DSSD should increase. The sensor rods come as part of the air duct assembly .

Note: W ait at least 45 seconds before repeating the test to allow the capacitor to charge fully .

Electronic Control Board

The electronic control board consists of 2 circuit boards connected by 2 ribbons. The boards are attached to the back of the control panel and control all washer functions. The boards are replaced with the control panel as an assembly .

If a faulty board is suspect, check for continuity across the fuse and visually inspect the surge protector mounted on the board. If no continuity is read across the fuse or if the surge protector appears burnt or damaged, replace the board.

Caution:

FuseFuse

Surge

Protector

• When replacing the control panel, remove the protective coating from the overlay prior to power-up to prevent ESD from damaging the new board.

• T o prevent electrostatic discharge, ground yourself to the washer cabinet or use an ESD wristband.
