Connect the desired speed tap to the “EAC” terminal and

the neutral tap to the neutral terminal on the ignition control

(refer to the furnace wiring diagram). The ignition control

will control the motor’s operation, including a nominal 20

second “on” delay with a call for heat and a nominal 180

second “off” delay when the thermostat is satisfied. It will

also operate the motor on a call for cooling, with no “on” or

“off” delays.

Verify that the unit is operating at the desired speed and

within the rise range as shown on the unit rating plate.

The correct replacement motor must be installed as soon

as possible to ensure continued satisfactory operation of

the furnace.

Control Diagnostics

Troubleshooting

Make the following visual checks before troubleshooting:

1. Check to see that the power to the furnace and the

integrated ignition/blower control board is ON.

The manual shutoff valves in the gas line to the furnace

must be open.

3. Make sure all wiring connections are secure.
4. Review the Sequence of Operation.
Start the system by setting thermostat above room

temperature. Observe system response. Then use the

information provided in this section to check the system

operation.

The furnace has a built-in, self-diagnostic capability. If a

system problem occurs, a fault code is shown by a red LED

on the control board. The control continuously monitors its

own operation and the operation of the system. If a failure

occurs, the LED will indicate the failure code. The flash

codes are presented in Table 12.

Fault Code History Button

The control stores the last five fault codes in memory. A

push button switch is located on the control. When the

push button switch is pressed and released, the control

flashes the stored fault codes. The most recent fault code

is flashed first; the oldest fault code is flashed last. To

clear the fault code history, press and hold the push button

switch in for more than 5 seconds before releasing.

High Heat State LED

On models, a green LED is provided on the control board

to indicate high heat state (see Table 13).

CFM LED

On models equipped with a variable speed motor, an amber

LED is provided on the control board to display CFM. To

determine what CFM the motor is delivering at any time,

count the number of times the amber LED flashes. Each

flash signifies 100 CFM; count the flashes and multiply by

100 to determine the actual CFM delivered (for example:

10 flashes x 100 = 1000 CFM).
