CHAPTER 7: TROUBLESHOOTING
7-2
7.2 Pilot Burner Malfunction (cont.)
3.
Check all connections for cleanliness and security.
C.
Pilot flame of proper size, but is unstable. Flame wavers and does not envelop the
thermopile completely at all times.
1.
Check for drafts that might be caused by air conditioning equipment or make-up air
apparatus. Turn air-moving equipment off and recheck the pilot.
7.3 Main Burner Malfunctions
A.
Main burner will not come "ON"; gas not detected at main burner.
1.
Check that the gas valve is open.
2.
Check that the pilot is ignited and is operating properly.
3.
Factory Authorized Servicer Only: Check the high-limit switch for continuity.
4.
Factory Authorized Servicer Only: Check the combination gas valve and replace if
defective.
B.
Main burner flames are small and appear lazy; shortening does not come up to temperature
quickly.
1.
Factory Authorized Servicer Only: Check gas pressure at the pressure tap of the gas
valve. Use dial type or standard water-type U-gauge manometer. With burner in
operation, the pressure should be 4" W.C. (10 mbar) for natural gas, and 11" W.C. (27.5
mbar) for propane. If not, remove the pressure regulator adjustment cover. Use
screwdriver to turn the adjusting screw for proper pressure. Replace cover, re-check
pressure and re-install pressure tap plug.
C.
Signs of excessive temperature; shortening scorches and quickly becomes discolored.
1.
Check operating thermostat. May be out of adjustment or calibration. Recalibrate if
necessary.
2.
Check gas pressure as outlined above.
3.
Shortening used is of inferior quality and/or shortening has been used too long. Replace
shortening.
4.
Ensure frypot is clean when refilling with new shortening.
