Door Lock Assembly - GE PGS908 Technical Service Manual

The thermal switch has a resistance value of 0 Ω
below approximately 190°F (88°C).
The resistance of the thermal switch can be checked
on the ERC. Place the control panel in the service
position. (See
Touch Panel and ERC
PGS908-Test at location J1 J1 pin 3 to pin 2 (door
locked) or pin 3 to pin 1 (door unlocked), for 0 Ω.
PGS968 and PGS975-Test at location CN2 pin 5 to
pin 4 (door locked) or pin 5 to pin 3 (door unlocked),
for 0 Ω.
Thermal Line Break Switch
The thermal line break switch disconnects power to
all range components when an over-temperature
condition exists in the burner box. The thermal line
break switch will open at 250°F and is not resetable.
Determine the cause of the over-temperature
condition before replacing the open thermal line
break switch.
The thermal line break switch has a resistance value
of 0 Ω below approximately 250°F (121°C).
The resistance of the thermal line break switch can
be checked on the ERC. Place the control panel in
the service position. (See
PGS908 - Test at location L1 to the non-ribbed (line)
side of the power cord for 0 Ω.
PGS975 - Test at location COM to the non-ribbed
(line) side of the power cord for 0 Ω.
To remove the thermal switches:
1. Remove the maintop burner assembly (see
Maintop Burner Assembly).
2. Note the placement of the wiring to the thermal
switch that is being removed. Disconnect the
wiring.
3. Remove the 2 hex-head screws that hold the
thermal switch in place.
4. Remove the thermal switch.

Door Lock Assembly

The door lock assembly consists of a lock motor
cam and switch assembly, lock hook, and mounting
plate.
The lock motor is energized when the control is set
for CLEAN and CLEAN TIME is selected. The K4 relay
contacts will close and complete the circuit that
supplies the voltage to the lock motor.
