ICM284
Fixed Speed Furnace Control Replacement Module
Replaces York modules: 03101280000, 100-825-04, 031-00661-701, 031-01280-000, HS 8201, 100-00825-04
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 ICM284 xed speed furnace control replaces the following York modules:
03101280000, 100-825-04, 031-00661-701, 031-01280-000, HS 8201, 100-00825-04
Specifications
Electrical
• Voltage Range: Line (208 to 240 VAC) @ 60Hz
• Ignitor: 5A @ 30 VAC
• Cool Blower: 30A, 2HP, 240 VAC
System Tests
Step 1: Flame Sensor Operation
Connect a DC microammeter in series with ame sensor. Initiate a heat call. After burners
ignite and stabilize, measure ame current. Nominal ame current is between 2.0 and 4.0
microamps DC. If ame current reading is less than 2.0 microamps DC, either replace or
remove and clean ame sensor with a ne grade steel wool. When the ame current falls
to 0.5 microamps DC, the furnace control will lock out.
Step 2: System Operation
1. Perform necessary safety checks. Consider ame safety, limit switch, and vent system.
2. Operate unit through a complete call for heat cycle.
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 shufe 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.
Step 1: Remove Existing Control
CAUTION!
To service control, and prior to disconnection, label all wires. Failure to do so may
result in wiring errors which 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.
4. Remove furnace blower and control access doors.
CAUTION!
Failure to turn off gas and electric supplies can result in explosion, re, death, or
personal injury.
6. Disconnect thermostat wires and humidier wires (if equipped with a humidier).
7. Disconnect line voltage, blower, electronic air cleaner wires (if equipped), and
transformer wires.
8. Remove screws or any other fasteners and old 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 humidiers,
evaporator coils, and vent systems in the area of the control.
Step 2: Install the New Control
1. Ground yourself. When handling circuit board, hold it by the edges.
2. Fasten circuit board with retaining screws.
3. Connect all line voltage, low voltage, and accessory wires.
4. Connect a 9-pin Molex connector to circuit board.
