Section 5 Service Procedures
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the dryer(s) before servicing.
• Close gas shut-off valve to gas dryer(s) before servicing.
• Never start the dryer(s) with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the dryer is properly grounded.

38. BURNER SYSTEM OPERATION
(Gas Models)
Refer to Figure 15
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 split-coil valve. Once
opened, the holding coil can hold the valve
open without assistance from the booster coil.
The current shunted around the secondary coil
by the sensor, passes through the igniter causing
it to get hot.
c. Burner Circuit
In approximately 30 seconds, the igniter attains
ignition temperature and the sensor (located on
burner housing beside the igniter) contacts
open. A circuit is then completed through the
secondary valve coil, opening the valve and
allowing gas to flow. Ignition is made and the
heat from the burner flame causes the sensor
contacts to remain open.
