FAULT CODE 012, 013, 014 OR 015: OVERHEATING, EXCESSIVE TEMPERATURE AT FLAME SENSOR, POSSIBLE OVERHEATING DETECTED OR TOO MANY OVERHEATS. (Cont) -726250865

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 overheat sensor resistance is between 150K ohms at 13_F (-25_C) and 10K ohms at

77_F (25_C).

A multimeter must be used when measuring continuity across the overheat sensor. Failure to do so

may cause inaccurate readings.

CONTINUITY TEST

(1) Ensure arctic heater temperature is

between -13_ and 77_F (- 25_

and 25_C).

(2) Set multimeter to ohms setting.

(3) Connect multimeter positive (+) lead

to blue wire at arctic heater internal

harness connector, terminal 11.

(4) Connect multimeter negative (-) lead

to blue wire at arctic heater internal

harness connector, terminal 17.

(5) Is resistance across arctic heater

overheat sensor between 10K and

150K ohms at room temperature?

(a) If resistance reading is not between

10K and 150K ohms at room

temperature, replace arctic heater

overheat sensor (Para 18-2.2).

(b) If resistance reading is between

10K and 150K ohms at room

temperature, go to Step 2 of

this Fault.
