UNIT DAMAGE HAZARD
Failure to follow this caution may result in damage to unit
components.
Make sure limit switch wire does not contact any metallic
component such as the gas valve. If wire is shorted, the 5-amp
fuse on furnace control board will open and the unit will
not operate.

To retrieve last code, remove 1 of the red main limit wires for 1 to
4 sec until the LED light goes out, then reconnect it. (Do not leave
red wire disconnected for longer periods of time as the control will
assume an overtemperature condition exists and will respond with
blower operation.) This places the control in the status recall mode
and displays the first code stored in memory.
