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 open.
2.
Check that the pilot is lit and is operating
properly.
3.
The gas control may be defective; replace if
necessary.
4.
Check high temperature safety switch.
Replace if defective.
5.
Check air prover switch as follows:
Move actuating lever at switch to make sure 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
switches 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. Clean out
flue and blower wheel.
2.
Blower motor may have overheated and shut
off on thermal overload. This condition will
correct itself when motor cools (20 minutes).
If problems with blower overheating persist,
call for service.
3.
If fryer is equipped with a Thermatron
Controller, the temperature probe or the
Thermatron board may be defective. Call for
service.
Main burner flames are small
and appear lazy; Frying
compound does not come up
to temperature quickly.
1.
Check gas pressure at the pressure tap of the
gas control. Use a standard water-type U-
gauge manometer. With the burner in
operation, the pressure should be about 4"
WC on natural and 11" WC on propane gases.
If not, unscrew the cover of the pressure
regulator adjustment, use a screwdriver to
turn the adjusting screw clockwise to increase
gas pressure (or counterclockwise to
decrease the pressure). Replace cover and
plug.
