FAILURE
Drive motor runs, but
dryer does not heat.
(gas dryer)
CHECK
1. Is the gas turned on?
2. Disconnects power from the dryer,
raise the main top, reconnect power,
set the fabric selector switch to high
and start the dryer. Measure the
voltage drop between terminal 5 (the
terminal with the blue wire on it) of
the fabric selector switch and neutral.
3. Disconnect power and remove the
accumulator. Masure the resistance
between the terminals of switch B.
4. Disconnect power from the dryer,
turn the gas off to the dryer,
disconnect the belt from the motor,
and remove the front panel. Set the
fabric selector switch to high and
observe the igniter for one minute.
5. Measure the voltage drop from the
terminal on the sensor with orange
wire to neutral.
6. Remove power, unplug the igniter and
measure the resistance of the igniter.
Yes, go to step 2.
No, turn the gas on.
CORRECTION
If the meter read zero, go to step 3
If the meter reads line to neutral, go to step.
4.
If the meter read zero, the control thermostat
defective.
If the meter reads infinity, switch B is
defective.
If the igniter glows full brilliance or glows dim,
the full minute, defective sensor.
If the igniter close full brilliance then dims,
defective gas valve or gas supply.
If the igniter does not glow, go to step 5.
If the meter reads zero, defective safety
thermostat.
If the meter reads line to neutral voltage, go
to step 6.
If the meter reads infinity, they igniter is
defective.
If the meter reads between 50 and 400 ohms,
the drive motor is defective.
Note:
Always check for defective wiring between the components before condemning any component.
