WIRING SCHEMATIC

49. BURNER SYSTEM OPERATION (Figure 50)

Components

This burner has four basic components: A siliconcarbide (glow bar) igniter, burner tube, flamesensor, and a two-stage gas valve consisting ofa split-coil valve and a secondary coil valve. Thesplit-coil valve is opened when the dryerthermostat calls for heat, while the secondaryvalve does not open until the igniter has attainedignition temperature.

Pre-Ignition Circuits

When the dryer thermostat calls for heat, circuitsare completed through the holding coil, flamesensor, booster coil and igniter. Both coils mustbe energized to open split-coil valve. Onceopened, the holding coil can hold the valve openwithout assistance from the booster coil. Thecurrent shunted around the secondary coil by theflame sensor, passes through the igniter causingit to get hot.

Burner Circuit

In approximately 30 seconds, the igniter attainsignition temperature and the flame sensor(located on burner housing beside the igniter)

contacts open. A circuit is then completedthrough the secondary valve coil, opening thevalve and allowing gas to flow. Ignition is madeand the heat from the burner flame causes theflame sensor contacts to open.

IGNITION SYSTEM FEATURES (Figure 50)

MOMENTARY POWER INTERRUPTION: Uponresumption of power, flame sensor contacts willstill be open, permitting secondary valve to open.However, with the secondary coil in the circuit,the booster coil cannot draw enough current toopen the split-coil valve. When flame sensorcontacts do reclose, the secondary valve willclose, and the burner system will be in thenormal pre-ignition circuit.

FLAME FAILURE: In case of flame failure, theflame sensor contacts will reclose in about 45seconds. This will close the secondary valve andthe burner system will be in the normal pre-ignition circuit.

IGNITION FAILURE: If flame is not establishedas flame sensor contacts open, secondary valvewill remain open until flame sensor contactsreclose. Flame sensor will continue to recycle theigniter and secondary valve (about once perminute) until ignition is made or dryer is turnedoff.

87. CONTROL REPLACEMENT (Figure 64)

When a problem with the electronic control isdetected during the diagnostic cycle, or whilemaking the electrical tests we have discussed,the control is replaced as a complete unit. Due tothe sensitivity of the electronic control, carefulhandling is required. As a precautionarymeasure, we recommend the use of a groundedwrist strap when handling the electronic controls.The wrist strap, cord and alligator clip aredesigned to carry away any electrostatic chargefrom your body and to direct the charge to anavailable ground. By using this static protectiondevice, potential electrostatic discharge problemsassociated with the handling of the electroniccontrol will be minimized. Always handle theelectronic control by the metal edges. If a wriststrap is not available, touch the dryer while it isplugged in before handling the control todissipate any charge.

To replace the control, first unplug the dryer.Remove all of the wires connected to the controland take out the screws securing the control tothe control hood. When removing wires from thecontrol, hold down on the board near theappropriate terminal, and disconnect the wiresusing a pliers. Do not pull on wires.

Figure 64

The new control is supplied in a special anti-static wrapping, and protected by anti-staticfoam. While holding the metal edges, remove thecontrol from the foam and the wrapping. Lift theinoperative control off the mounting bracket andplace it on the anti-static wrapping. Beforepositioning the new control in the control hood,peel off the protective plastic coating from thefront side of the control, then fasten the controldown with the screws. Following the wiringdiagram, reconnect the wires to the new control,then replace the control hood.

IMPORTANT: Take care when handling theoriginal control. It must be carefully placed inthe anti-static wrapping and the anti-static foamwhich was removed from the new control. Acopy of the replacement report, shown on Page87, must be completely filled out and returnedwith the control. Warranty credit will not beissued if the control is not wrapped properly.

The AUTOMATIC CYCLES will determine thetime needed by use of a moisture sensor locatedbelow the lint screen (Figure 41) and athermistor.

The TEMP/DRYNESS control should be set justto the right of MED/NORMAL.

90. NO HEAT

This cycle will tumble and circulate roomtemperature air through the load. Use for anyitems that should not be dried with heat.

Set TIMER for length of time desired.

91. TIME DRY

The TIME DRY cycle will operate the dryer forthe number of minutes set by the user. In thiscycle, the temperature is set by the TEMP/DRYNESS control.
