red color. What does matt need to do:
A) replace the safety valve
B) clean or replace the pilot until the tip of the safety
heats cherry red
C) increase the gas pressure
D) replace the thermostat as the bypass must be
failing - ....ANSWER...B
,Jim is called out to service a gas fryer with a solid
state temperature control circuit. When the
temperature control calls for heat the solenoid
chatters on and off. Jim needs to:
A) Replace the solenoid valve
B) Connect a resistor across the solenoid valve
terminals
C) Replace the temperature sensor probe
D) Check the temperature control circuit to find the
cause of the erratic voltage - ....ANSWER...D
Joe is working on a heavy duty restaurant range. He
has his manometer connected to the main
burner manifold and notices that the pressure falls a
little more with each burner that is turned
on. The problem is ______?
A) Insufficient gas pressure
B) Insufficient gas volume
C) Excessive gas volume
D) Insufficient secondary air - ....ANSWER...B

are operating properly - ....ANSWER...D
Bob is working on a convection oven and the
customer is complaining that the pilot will not stay
lit. He connects his volt meter through the
thermocouple in line test adaptor and lights the pilot.
The meter reading slowly rises to 22 millivolts, but
when bob releases the button on the safety
valve the pilot goes out. The problem is:
A) A bad safety valve
B) A weak thermocouple
C) A pressure regulator problem
D) A low gas pressure - ....ANSWER...A
A gas fired conveyor oven is slow in firing but heats
to the set temperature. Then the high flame
disappears and the temperature drops until the oven
is barely warm. Then it heats to
