Inlet Thermistor; Manual Reset Thermostat - GE DCCH480EK Technical Service Manual

Manual Reset Thermostat

The manual reset thermostat is attached to the top
of the heater assembly and located to the right of
the auto reset thermostat, as viewed from the back
of the dryer. Two blue wires are connected to the
manual reset thermostat. The thermostat monitors
incoming air temperature.
If the thermostat reaches a temperature beyond its
maximum temperature rating, it will trip and disable
power.
The manual reset thermostat opens at 293°F
(145°C).
If the manual reset thermostat trips, do not reset
until the following dryer components have been
checked thoroughly for damage or deformation.
Heater: Remove heater and check for any physical
and functional damage. (See
Motor: Check motor and blowers for proper
operation.
Air Duct guide: Examine carefully and look for
any deformation due to the excess heat that
caused manual reset thermostat to trip. A warped
or deformed air duct guide can effect drying
performance.
The manual reset thermostat is not available
as a separate part. To replace the manual reset
thermostat, it is necessary to replace the heater
assembly. (See

Inlet Thermistor

The inlet thermistor is located above the heater
assembly. The thermistor measures incoming air
temperature and responds to temperature changes.
The thermistor provides temperature change
information to the control board. The control board
makes heating decisions based on this information.
The thermistor has an approximate resistance value
of:
Temperature
32°F
50°F
68°F
86°F
104°F
122°F
140°F
158°F
176°F
194°F
212°F
Operation of the thermistor can be checked by
using the service test mode. (See
Specifi c failures associated with the inlet thermistor
can initiate error codes tE2 and od. (See
To access the inlet thermistor it is necessary to
remove the top and back cover. (See
.)
