CABINET CONTROL PROBLEMS (cont'd)
Malfunction of Pilot Burner flame
The Pilot Burner should have a steady blue flame about 1" long which must envelop and
heat the thermocouple tip in order for the Main Burners to ignite on demand.
Check that required gas pressure is available to Gas Combination Control Valve.
Unusually strong floor drafts may interfere with pilot flame preventing it from properly
heating the thermocouple tip and result in ignition failure of Main Burners.
An inadequately heated thermocouple tip can result from an unusually short pilot flame
which most often can be attributed to insufficient or irregular gas supply to Pilot Burner.
Examine the gas supply tube (1/4" OD) that it has no severe kinks. Remove tube and check
that free flow of gas is possible through it. Also, if the orifice of the Pilot Burner
is slightly
plugged, gas flow will be impeded causing an irregular flame and will require replacement.
Main Burners refuse to ignite
Assuming that the Pilot Burner flame is of proper size and envelops the thermocouple tip,
but the Main Burners refuse on demand to ignite, then possibly the Thermocouple
Assembly is malfunctioning. Examine that proper contact of thermocouple to Gas
Combination Control Valve is being maintained by checking that the nut connection at Valve
is initially finger tight with an additional 1/2 turn by wrench. If malfunction persists, replace
Thermocouple Assembly and retest.
Finally, when all above corrections have been made, assume that Gas Combination
Control Valve is defective. Replace Valve, it is not recommended that disassembly and
repair be attempted.
