Introduction
Electrostatic Discharge (ESD) Precautions
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.Disconnectallpowertothefurnace.Donottouchthecontrolorthewiringpriortodischargingyourbody’selectrostaticcharge
to ground.
2. To ground yourself, touch your hand and tools to a clean, metal (unpainted) furnace surface near the control board.
3.Servicethefurnaceaftertouchingthechassis.Yourbodywillrechargewithstaticelectricityasyoushufeyourfeetormove
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 the used and new controls in separate;
containers before touching ungrounded objects.
6. ESD damage can also be prevented by using an ESD service kit.

Flame Sense Troubleshooting Tips
Flame not established
1. If ame is not established during the 4 second initial sequence then the control will start the next trial for ignition in 60 seconds.
2. There will be 2 more attempts to ignite after the 60 seconds delay, before the respective fault code is triggered and the ignition
trials are stopped.
3. If ame has not been established after the 3 trials for ignition; the control will enter a 60 minute soft lockout and ash the
respective fault code. The lockout can be cleared by cycling the W call or the input power.
4. The blower motor is off until 30 seconds after ame is established and sensed.
Flame out
1. Flame out is considered when ame is lost during heating.
2. When a W signal is present and ame is not sensed, then gas valve will disengage until the next trial for ignition.
3. If ame is not established on the immediate sequence (2 above) then the control will continue with 2 additional trials for ignition.
4. The Inducer and Blower motors will continue running during the ame out scenario.
Flame out of sequence
1. Flame out of sequence represents a scenario when ame is sensed while the gas valve is de-energized.
2. The Inducer and Blower motors will be engaged (if not already running) and continue running for as long as the fault condition
is present.
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. Verify the sequence of operation.
Install New Control
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, re, death, or personal injury.
4. Remove furnace blower and control access doors.
5. Disconnect thermostat wires and humidier wires (if equipped with a humidier).
6. Disconnect line voltage, blower, electronic air cleaner wires (if equipped), and transformer wires.
7. Remove screws and any other fasteners, and the old circuit board.
8. Examine control and control box to check for water stains.
9. 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.
Remove Existing Control
Sequence of Operation
On the application of power, the ICM2812 will continuously monitor the rollout switch, limit switch, pressure switch, gas valve output
and ame sense.
During a Call for Heat, the control makes sure the limit switch is closed and the pressure switch contact is open before turning on the
Inducer blower, which will be energized for the 30-second pre-purge. Following the pre-purge period, the pressure switch contact is
closed and power is applied to the hot surface ignitor (there is a 19-second warm-up period), both gas valves are energized. Once
ame is established and sensed the ignitor is turned off.
1STG (Single Stage): After the 30 seconds heat blower on delay the high (HI HEAT-H) speed is energized.
2STG (Dual Stage): After 5 seconds the high gas valve (MV HI) is turned off. The low (LO HEAT-H) speed blower will energize
after the 30 seconds heat blower on delay. The ICM2812 will switch to second stage heat after 5 minutes of
continuous operation; the high gas valve (MV HI) is re-energized along with the low gas valve (MV LO) and the
main blower will switch to the high (HI HEAT-H) speed for the duration of the heat call.
Once the heat call is satised; the blower is switched to the low (LO HEAT-H) speed; the Inducer Draft motor turns off after the 25
second post purge delay and the blower motor turns off after the preselected heat blower off delay of either 100 or 150 seconds.
Fan: A fan call from the thermostat will energize the blower motor without delay at low (LO HEAT-H) speed. The blower is turned off
without delay when the Fan call is removed.
Cooling: A cooling call from the thermostat will energize the blower motor at high (COOL-H) speed after the 6 second cool blower
on delay. The blower is turned off 45 seconds after the cooling call is satised.
To review the fault history; press and hold the Fault Recall
button and release once the LED goes out. The previous
ve fault codes will be displayed. The LED will turn off
momentarily and then go solid after the last fault has been
displayed.
The ICM2812 will not respond to thermostat calls while the
fault history is being displayed.
To clear the fault history; press and hold the Fault Recall
button and release once the LED starts ashing. The LED will
turn off momentarily and then go solid after the fault history
has been cleared.
The fault history will not erase while the ICM2812 is
performing a heating or cooling call.

Note 1: For American Standard/Trane, York PCLU and York P3UR furnaces: Install the black wire labeled “10” from pin 5 to pin 11 of the
12-pin harness which is connected to the furnace.
Note 2: There are some Rheem/RUUD furnace models which performed ame sense differently. Please read the information below before
testing the furnace!
1. Rheem/RUUD furnaces without a separate ame sensor will require the purchase of a Rheem ame sensor kit (62-24044-71) to be wired to
pin 7 of the 9-pin harness which is connected to the furnace.
2. Rheem/RUUD furnaces with a separate ame sensor which is NOT routed through the 9-pin harness will require removal of the ame
sensor wire from the existing connection and rewiring it to pin 7 of the 9-pin harness which is connected to the furnace.
3. Rheem/RUUD furnaces which have a separate ame sensor already routed to pin 7 of the 9-pin harness will not require this modication.
Connect the other end of the furnace harness into the ICM2812 harness labeled “2”, connect the other end of this harness to the ICM2812
circuit board and connect the orange wire to the “FS” (ame sensor) terminal.
