Subject: Tips to Determine Oven/ Griddle Pilot Outage Root Cause
Please be advised we have had instances of pilot outages on our new range line, where the onsite
technician has not been able to determine root cause. Enclosed is a list of items to review, to
determine intermittent pilot problems.
1. Check the Thermostat knobs. Knobs that have the tabs broken or are mis-aligned on the
thermostat bodies will cause pilot outage while trying to adjust temperature values. This will
not apply to any Flame-failure type units.
2. Ensure Back Guards and High-Shelves are properly mounted on the rear of the range. Any
deviation or leakage on the guard or shelf install could cause the unit to “front-vent” and
extinguish the oven/griddle or top section pilot.
3. Ensure dynamic manifold pressures are according to factory specification. Check incoming
supply values, and /or any type of supply pressure fluctuation. * NOTE* 48” and 60” models
require a 1” regulator to ensure proper manifold pressures are within defined specifications.
4. Check for Ventilation cross drafts, or drafts along the floor. Inconsistent vent pressure or flue
blockages can conceivably cause the pilots to “drop out” during normal cycling of the
thermostats
5. Ensure pilot and burner orifices are sized correctly to ensure the proper amount of fuel at
the pilot and burners to ensure stability of the pilot flame. Check that the pilot orifice is
seated properly on the pilot olive sleeve and there are no leaks at the compression fittings
or pilot line.
6. Check milli voltage from the thermocouples to ensure the correct amount of milli voltage is
present. Refer to your unit’s technical service manual to determine the correct amount of
voltage.
