The door lock assembly mechanically locks and
unlocks the door, and gives door switch and door
lock status to the IMC board. Each time the solenoid
is operated the position of the mechanical lock and
the door lock switch changes position.

The door can be manually unlocked by press-
ing down on the manual unlock lever (See Image
Above).

Locking and Unlocking

Neutral is switched to the door lock assembly by
the door switch. L1 is pulsed to the other side of the
solenoid from IMC J701-5 when the door is locked
or unlocked.

Door Position Detection

When the door switch is closed, neutral is present at
IMC J701-5 indicating that the door is closed. When
the door switch is open, neutral is not present
at IMC J701-5 indicating that the door is open.

Lock Position Sensing

When the door is locked the lock switch will be
closed, causing neutral to be present at IMC J701-1
indicating that the door is locked. When the door is
not locked the lock switch will be open and neutral
will not be present at IMC J701-1 indicating the door
is not locked.

Door Lock Assembly Tests

1. Enter Service Mode.
2. Run Test 14.

a. Press the

Start

button to begin the test.

b. The door will lock and the

LC

Door Lock Assembly Diagnostics

Solenoid Not Operating
1. Disconnect power to unit.
2. Disconnect IMC J701. While holding the door

switch in, check resistance between IMC J701-5
and IMC J101-6.

a. If resistance is greater than 15

Ω

, check wiring

and replace door lock assembly if wiring is ok.

b. If resistance is ~15

Ω

replace IMC board.
