Introduction
The new GE dryer has the following features:
Large 7.0-cubic foot dryer drum
Drying Rack - Available on some models, for drying delicate items such as washable sweaters.
Drum Lamp
My Cycle selection saves a favorite cycle for future use.
Built-in service test mode. Specifi c dryer components can be operated. Error codes are recorded and
• accessible on the control panel's 7-segment display.
Dual Thermistors - Thermistors are more sensitive to temperature changes and can relay the
• information faster than thermostats. The dryer utilizes dual thermistors to monitor incoming air temperature as well as air temperature leaving the drum. The sensors work together with the variable heater and the blower to provide consistent, even heat.
Moisture Sensor - The moisture sensor allows the control to monitor the fabric for moisture content and
• end the cycle at the desired moisture level.
Flush Door Handle
Reversible Door
UV Stabilizers - The control panel, control panel cover, and door outer panel have UV stabilizers to
• prevent yellowing when exposed to sunlight.
The GE dryer can be installed on top of the GE
• Front Load Washer. (Stacking kit supplied with washer.)
Pedestal available at additional cost. White
• (model number SBSD227FWW) and granite (model number SBSD227FGG).

Operation Overview
Air enters the dryer cabinet, passing thru the heating elements and into the drum. The hot air heats the wet clothes, gradually removing their moisture in the form of water vapor. The moist air is vented through the dryer exhaust. Overall heater temperature is regulated by means of two temperature sensors, an inlet sensor, located near the heating elements, and an outlet sensor, located at the blower. An additional safety thermostat, located near the heating elements, shuts off the heating elements if they overheat. Also, the outlet backup thermostat, located near the blower, provides additional safety and cycles the heaters if temperature goes above the outlet temperature range.

The typical dryer cycle progresses as follows:
1. A cycle is selected and the start key is pressed.
2. The motor is activated.
3. The heater coils (burner for gas models) are activated. The coils (burner) cycle on and off to achieve the desired temperature throughout the heating portion of the cycle.
4. If sensor drying is selected, the heater coils (burner for gas models) are activated. The coils (burner) cycle on and off until the load has achieved the desired dryness level.
5. If timed drying is selected, the heater coils (burner for gas models) are activated and cycle on and off for the selected time at the selected temperature.
6. The heater coils (burner for gas models) discontinue operation after the dryness level or elapsed time has been achieved.
7. The motor continues operating until the clothes temperature drops below specifi ed temperature (Cool Down).
9. The display turns off.

Ignitor Circuit Operation
The glo-bar ignitor circuit is made up of the following components: a gas valve with safety and main valves, ignitor, and a fl ame detector. The safety valve is actuated by a double coil that comprises a safety coil (resistance approximately 1350 ohms) and a booster coil (resistance approximately 550 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).

Gas Valve Open
The fl ame detector (< 1 ohm) is mounted on the combustion chamber. It is normally in the closed position (N.C.). The fl ame detector is opened by the radiant heat produced by the glo-bar and once open, the fl ame detector will be held open by the radiant heat produced by the gas fl ame.
When the control system calls for heat, the following circuits are energized:
1. N- through detector, ignitor, 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. fl ame detector. When the glo-bar reaches ignition temperature, in approximately 60 seconds or less, the fl ame detector is heated and opens, which places the main coil in series with the glo-bar. The main valve opens, allowing gas to fl ow 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 fl ame detector is held open by the radiant heat from the gas fl ame. 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 fl ame detector cools and resets, in approximately 30 seconds.

Remove the 2 Phillips-head screws that attach
6. the power board to the power board support.
Note: The 2 sensor rods in the air duct assembly are not replaceable. To replace the sensor rods, replace the air duct assembly. (See Air Duct Assembly.)
The sensor rods are connected to the
• main control board. The rods are spaced approximately ½-in. apart, which creates an open circuit to the control.
The control board utilizes a low-voltage
• capacitor that charges to approximately 5 VDC when the circuit is open and discharges to less than 1 VDC when the circuit is shorted.
When wet clothes tumble across the two
• rods, the clothes create a very low resistance between the rods, which discharges the capacitor.
As the clothes become dry, their resistance
• value increases and the charge across the
capacitor builds to approximately 5 VDC.
Proper leveling of the dryer is vital for accurate
• sensor drying. If the front of the dryer is raised too high, clothes will tumble toward the rear of the drum, preventing contact with the sensor rods. This could produce a false dryness reading.
