Inlet Control Thermistor; Inlet Safety Thermostat - GE DHDVH52 Technical Service Manual

Inlet Safety Thermostat

The inlet safety thermostat is located on the top
left area of the heater housing. It is left of the
inlet control thermistor. The thermostat monitors
incoming air temperature.
If the thermostat reaches a temperature beyond its
maximum temperature rating, it will trip and disable
power to the heating elements.
On electric dryers, the inlet safety thermostat opens
at 210°F (99°C) and will automatically reset at 180°F
(82°C). On gas dryers, the inlet safety thermostat
opens at 300°F (149°C) and will automatically reset
at 260°F (127°C).
To remove the inlet safety thermostat:
1. Remove the top, control, and front panels. (See
Top Panel, Control Panel
2. Remove the drum. (See
3. Disconnect the black and orange wires from the
inlet safety thermostat.
4. Remove the single Phillips-head screw then

The inlet control thermistor is located on the
top left area of the heater housing. It is right
of the inlet safety thermostat. The thermistor
monitors incoming air temperature and relays the
information to the power board.
Inlet control thermistor resistance values:
80 Ω at 86°F (30°C)
•
100 Ω at 77°F (25°C)
•
120 Ω at 69°F (20.5°C)
•
Operation of the inlet control thermistor can be
checked by using service test mode t08. (See
.)
Test Mode
Specifi c failures associated with the outlet control
thermistor can initiate error codes E02 and E04. (See
