Note On Intermittents

If Code B113 is set with Code B115, check for an intermittent open in circuit No. 736. If an intermittent Code B113 is being set, manipulate related wiring while observing BD25 display. If failure is induced, reading will jump from its normal value to a reading outside the range of -29°F (-34°C) to 209°F (85°C).

If value indicated by BD25 display is not reasonably close to actual temperature of air at sensor, check for poor terminal contact or replace sensor.
