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 150K ohms at -13_F (-25_C) and 10K ohms at
S
77_F (25_C).
A multimeter must be used when measuring continuity across overheat sensor. Failure to do so
S
may cause inaccurate readings.
VOLTAGE 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, replace arctic
heater overheat sensor
(Para 18-2.2).
(b) If resistance reading is between
10K and 150K ohms, replace arctic
heater control unit (Para 18-2.2).
