PHASE 3 TESTING
Set the upper compartment TIMED/MANUAL switch to the MANUAL position.
IT.3-1 Does the burner fan motor start when MANUAL mode is set?
Printed 3/93
This phase of testing pertains to the components associated with manual] controlled
steaming functions. After completing Phase 2 Testing, verify that the following
conditions are set to start Phase 3 testing:
• The right side and front access panel are removed and the float assembly, relays
and contractors are clearly visible.
• The Main Disconnect Switch is in the ON position and the 3-minute blowdown
cycle has stopped.
• The ON/OFF power switch is in the ON position.
• Both upper and lower compartment TIMED/MANUAL switches are in the
TIMED position.
• Both upper and lower compartment timers are set for zero minutes.
a. For Key Pad Control Panels: The timer display is blank while the ON/OFF
switch is set to OFF. If the timer is not zeroed (00:00) when power is turned
on, press and hold the CLEAR key on the key pad control panel until the
timer is zeroed.
b. For Dial Timer Control Panels: Turn the dial counter clockwise until it
points to the 0 mark.
• The water in the steam generator has heated to pre-heat temperature. (i.e. The
burners have cycled from on to off at least once.) The burners must be off when
starting this test.
NOTE: Selecting MANUAL mode for either cooking compartment activates the
steam valve, the condenser valve, and the burner relay (R1 or R2) for that
compartment First test the upper cooking compartment.
NOTE: The burner relay (R1 or R2) energizes relay R3 starting the fan motor and
the burner ignition sequence. If the fan does not trigger the air prover pressure
switch, the burners do not light.
Failure of any of five components can prevent the burner fan from starting the burner
ignition sequence in Manual mode.
1. Check the TIMED/MANUAL switch according to component test CT:9.
2. Depending on the cooking compartment controls being tested, check the relay R1
or R2 according to the relay testing instructions in Component Testing
Fundamentals.
