YSCFC24 SERIES FLATBOTTOM GAS FRYERS 

CHAPTER 7:  TROUBLESHOOTING 

 

 

 

FACTORY APPROVAL MUST BE OBTAINED PRIOR TO ANY WARRANTY WORK BEING 

DONE OR FRYMASTER CANNOT BE HELD RESPONSIBLE. 

 
The following procedures 

must be performed

 by Factory Authorized Service Technicians, and are 

provided as an aid to expedite troubleshooting and repair of YSCFC24 Series frying systems. 
 

 
7.1  PILOT BURNER MALFUNCTIONS 

 
 

PROBLEM

 

CORRECTIVE ACTION

 

Pilot will not ignite; no 
evidence of gas at pilot 
burner. 

Ensure the combination gas valve is in PILOT position and that 
gas is available at the control valve (check quick-disconnect 
and/or gas-line connections for proper connection). 

Pilot burner ignites but will 
not remain lit when gas 
knob is released. 

Pilot flame may be adjusted incorrectly.  Adjust flame to 1½" 
high by turning pilot flow adjustment screw. 

 

Pilot burner ignites 
properly and burns 
properly, but goes out 
when the exhaust blower 
comes on. 

1. 

Pilot flame may be adjusted too low, even though it 
appears to be satisfactory.  Re-adjust higher as described 
earlier. 

 

2. 

Pilot flame may be adjusted too high and is on the verge 
of blowing out. Re-adjust lower.
