FAULT CODE 012, 013, 014 OR 015: OVERHEATING, EXCESSIVE TEMPERATURE AT FLAME SENSOR, POSSIBLE OVERHEATING DETECTED OR TOO MANY OVERHEATS. (Cont) -726250867

TM 9-2320-364-34-1

Remove all jewelry such as rings, dog tags, bracelets, etc. If jewelry or tools contact positive electrical circuits, a direct short

may result. Damage to equipment, injury or death to personnel may occur.

NOTE

Arctic heater flame sensor resistance is between 900 ohms at 13_F (-25_C) and 1100 ohms at 77_F (25_C).

CONTINUITY TEST

(1) Ensure arctic heater temperature is

between -13_ and 77_F (- 25_

and 25_C).

(2) Connect positive (+) lead to gray wire

at arctic heater internal harness

connector, terminal 15.

(3) Connect negative (-) lead to gray wire

at arctic heater internal harness

connector, terminal 16.

(4) Is resistance across arctic heater

flame sensor between 900 and

1100 ohms at room temperature?

(a) If resistance reading is between

900 and 1100 ohms at room

temperature, replace arctic heater

coolant pump (Para 18-2.2).

(b) If resistance reading is not between

900 and 1100 ohms at room

temperature, replace arctic heater

flame sensor (Para 18-2.2).
