1.9 Troubleshooting Guides
FACTORY APPROVAL MUST BE OBTAINED PRIOR TO ANY WARRANTY WORK BEING
DONE OR DEAN 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 24G Series frying systems.
1.9.1 Pilot Burner Malfunctions
PROBLEM CORRECTIVE ACTION
Pilot will not ignite; no
evidence of gas at pilot
burner. 1. 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).
2. Remove pilot gas supply line and check for dirt. Blow out with
compressed air if necessary, then reinstall.
3. Check pilot burner orifice for dirt.
Pilot burner ignites but
will not remain lit when
gas knob is released. 1. Check that the lead from the thermocouple is tightly screwed
into the pilotstat power bushing on the gas control.
2. Remove end of thermocouple lead from pilotstat power unit
bushing and clean with fine sandpaper. Also check that
bushing is clean.
3. Thermocouple possibly defective (millivolt output should be 12-
28mv); replace.
4. Pilot flame may be adjusted incorrectly. Adjust flame to 1-½"
high by turning pilot flow adjustment screw.
Pilot burner ignites
properly and burns
properly, but goes out
when the exhaust
blower comes on. 1. 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.
2. Pilot flame may be adjusted too high and is on the verge of
blowing out. Re-adjust lower.
3. Pilot flame may be adjusted too low, even though it appears to
be satisfactory. Re-adjust higher as described earlier.
