B. Make sure that the Timer wiring is correct.
For the 60 Minute Timer: Terminal "4" on the back of the Timer should be connected to
the Oven Power Switch. Terminal "6" on the back of the Timer should be connected to
either terminal on the Buzzer Alarm. Make sure all connections are clean and tight.
For the 24 HOUR Timer: The Terminals marked "1a" and "2a" should be connected to
the Oven Power Switch. The terminal marked "1c" should be connected to the .063 amp
Fuse leading to
L–1 (120v)
on the
Hold
Control Circuit Board. The terminal marked
"2b" should be connected to the .063 amp Fuse leading to
L–1 (120v)
on the
Temperature
Control Circuit Board. The terminal marked "3" should be connected to
any neutral or group of neutral (WHITE) wire. Make sure all connections are clean and
tight.
C. Turn the Timer Knob back and forth several times to free it from any possible sticking.
D. If the Timer still does not run, or runs only after the Knob is turned back and forth
several times, the Timer must be replaced.
VIII. The Buzzer Alarm does not sound or is not very loud:
A. Because of space considerations the volume adjustment shaft on the Buzzer Alarm must
sometimes be cut off. Make sure the shaft stub is turned clockwise as far as it will go
(the highest volume setting).
B. Check the Timer for proper operation (refer to
VII - - Oven Timer Does Not Run
).
C. Make sure the Buzzer Alarm wiring is correct. One Buzzer terminal should be
connected to terminal "6" on the back of the Timer. The other Buzzer terminal is
connected to any neutral or group of neutral (WHITE) wire.
D. If all connections are correct, clean and tight and the Buzzer still does not operate it
must be replaced.
COOK–N–HOLD (optional):
IX.
The Temperature Controls are set and the 24 Hour Timer is at a setting
other than "0", but the Oven does not heat:
Your COOK–N–HOLD option is wired so that the Oven will bake at the indicated Oven
temperature for the period of time set on the 24 Hour Timer. When the 24 Hour Timer
reaches "
0
" the temperature then switches to the setting on the Hold Control. The product
will be held at that temperature until the unit is turned
OFF
or the Hold setting is changed.
INTERNALLY GENERATED STEAM (optional):
X.
The Steam Switch for INTERNAL STEAM is held ON and no steam is
observed after one to two minutes:
The INTERNAL STEAM option is activated by the spring-loaded Steam Switch. This
activates the Water Solenoid Valve, releasing a timed spray of water through the Injection
Nozzles and into the Blower Wheel. If the wiring to the Solenoid Valve and Steam Switch is
correct and all connections are tight, depressing the Steam Switch should produce an audible
sound from the Solenoid Valve and a fine water mist should be released into the Oven.
