Safety Considerations
Only trained personnel should install or service heating equipment.
When working with heating equipment, be sure to read and
understand all precautions in the documentation, on labels, and
on tags that accompany the equipment. Failure to follow all safety
guidelines may result in damage to equipment, severe personal
injury or death.
Introduction
The ICM282 fixed speed furnace control replaces the following
Carrier modules: HK42FZ004, HK42FZ007, HK42FZ008,
HK42FZ009, HK42FZ011, HK42FZ013, and HK42FZ016.
The ICM282 has incorporated LED diagnostics to assist in
troubleshooting. A fault code label is included in this package and
must be installed on the furnace.
Electrostatic Discharge (ESD) Precautions
CAUTION!
Use caution when installing and servicing the furnace to avoid
and control electrostatic discharge; ESD can impact electronic
components. These precautions must be followed to prevent
electrostatic discharge from hand tools and personnel. Following
the precautions will protect the control from ESD by discharging
static electricity buildup to ground.
1. Disconnect all power to the furnace. Do not touch the control
or the wiring prior to discharging your body's electrostatic
charge to ground.
2. To ground yourself, touch your hand and tools to a clean,
metal (unpainted) furnace surface near the control board.
3. Service the furnace after touching the chassis. Your body
will recharge with static electricity as you shuffle your feet or
move around, and you must reground yourself.
4. Reground yourself if you touch ungrounded items.
5. Before handling a new control, reground yourself; this will
protect the control. Store used and new controls in separate
containers before touching ungrounded objects.
6. ESD damage can also be prevented by using an ESD service
kit.

Specifications
CAUTION!
To service control, and prior to disconnection, label all wires.
Failure to do so may result in wiring errors that can cause
dangerous operation.
1. Turn thermostat to OFF position or set it to the lowest
possible setting.
2. Turn OFF electrical supply to furnace.
3. Turn OFF gas supply to furnace.
CAUTION!
Failure to turn off gas and electric supplies can result in
explosion, fire, death, or personal injury.
4. For 80% furnaces, remove control access and blower door;
for 90% furnaces, remove outer door assembly and remove
the two screws from blower access panel and set aside.
5. Disconnect thermostat wires and humidifier wires (if equipped
with a humidifier).
6. Disconnect line voltage, blower, electronic air cleaner wires (if
equipped), and transformer wires.
7. For 80% furnaces, remove retaining screws and remove
furnace control board from bracket; for 90% furnaces, remove
two screws from blower deck that hold the control box
assembly. Lower the control box assembly. Remove retaining
screw(s) from board and remove board from control box
assembly.
8. Remove wiring harness connectors from circuit board.
9. Examine control and control box to check for water stains.
10. Make repairs if any sources of water leakage are found.
Be sure to check humidifiers, evaporator coils, and vent
systems in the area of the control.
