CHAPTER 7: TROUBLESHOOTING
7-2
7.1 Pilot Burner Malfunctions (cont.)
PROBLEM CORRECTIVE ACTION
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 previously.
2. Pilot flame may be adjusted too high and is on the verge of
blowing out. Re-adjust lower.
3. With the exhaust blower in operation, the extra air causes the
pilot to blow out. The pilot assembly may be too low between
the burners. Adjust the pilot assembly to where the pilot hood
is above the burners.
7.2 Main Burner Malfunctions
PROBLEM CORRECTIVE ACTION
Main burner will not
come on even though
air blower is in
operation; no gas
pressure at main
burner. 1. Check that the combination gas valve is ON.
2. Check that the pilot is lit and is operating properly.
3. Check high-limit switch. Replace if defective.
4. Check air prover switch (sail switch) as follows:
Move actuating lever at switch to ensure it is not dragging in
the slots (use long tool to avoid burns). If so, bend the arm
carefully to clear the obstruction. Check the air prover switch
for continuity and replace if defective.
Air blower is not
operating, although
power is present at the
fryer. 1. Cooked product or other material may have fallen into the flue
and lodged in the blower wheel, preventing it from turning.
Remove debris and clean flue and blower wheel.
2. Blower motor may have overheated and shut off on thermal
overload. Allow motor to cool (20 minutes) for condition to
correct itself. If problems with blower overheating persist, call
for service.
3. The temperature probe or interface board may be defective.
Call for service.
