Flame Sensor (Qualified Servicer Only)

Under some conditions, the fuel or air supply can create a
nearly invisible coating on the flame sensor. This coat-
ing acts as an insulator causing a drop in the flame sense
signal. If the flame sense signal drops too low the furnace
will not sense flame and will lock out. The flame sensor
should be carefully cleaned by a qualified servicer using
emery cloth or steel wool. Following cleaning, the flame
sense signal should be as indicated in the Specifications
Sheet.

Before Leaving an Installation

• Cycle the furnace with the thermostat at least three
times. Verify cooling and fan only operation.
• Review the Owner's Manual with the homeowner and
discuss proper furnace operation and maintenance.
• Leave literature packet near furnace.
