TROUBLE
SHOOTING
PROCEDURE
lf entire
unit is not working,
proceed
as follows:
1.
Check
circuit
breaker
box to insure
that breaker
for hood is not tripped.
2.
Remove
printed
circuit
board enclosure
cover
by removing
two screws
securing
the cover.
(See Figure
I .)
CAUTION:
SHOCK
HAZARD
SOME CIRCUIT
BOARD COMPONENTS
(INCLUDING
HEAT SINKS) ARE NOT ISOLATED
FROM
THE AC POWER LINE.
3.
Disengage
five pin connector
from P. C. board
and check
for 115VAC
(nominal)
AC line voltage
between
the black
wire socket
(end socket)
and white
wire socket
(center
socket)
by inserting
VOM probes
into sockets.
4.
If voltage
is not present,
proceed
as follows:
a.
Turn off power
at breaker
box.
b.
Check
connections
in rear power
entry
box. (See Fig. 1.)
(1) Push in filter
