Reset After Control Lock-Out

If ignition has not been achieved for any reason after sev-
eral ignition cycles, the electronic control module will lock-
out the furnace. Ignition is no longer attempted. On fur-
naces with a self diagnostic control module, the control di-
agnostic light will then repeat a single flash followed by a
pause. When this occurs, it is possible to reset the control
by turning the thermostat setting below room temperature
for one to twenty seconds then returning the setting to the
desired temperature. The control may also be reset after a
lock-out by turning off the electrical disconnect switch to the
furnace for one to twenty seconds. The control will auto-
matically reset after one hour.
IMPORTANT: If the furnace must be reset frequently to
obtain satisfactory operation, a problem exists with your fur-
nace that must be corrected. Contact a qualified servicer.

Turning Off Furnace

1. Set the thermostat to lowest setting.
2. Turn off the electrical power supply to the furnace.
3. Remove the louvered door on the front of the furnace by
lifting up and pulling forward.
4. White Rodgers Model 36E36, Honeywell and Robertshaw
Gas Valves:
Turn the gas control knob clockwise
position (Figure 2, 3 or 5). The knob should turn easily
by hand. Do not use excessive force.
White Rodgers Model 36E22:
Push the selector switch to "OFF". (Figure 4)
5. Close manual gas shut-off valve external to the furnace.
6. Replace the door on the furnace.
Auxiliary Limit Control (Figures 6 & 7)
A secondary limit control is located on the blower deck. Dis-
connect electrical power prior to removing the nonlouvered
door to reach the secondary limit control. The control is in
addition to the main limit control and shuts the furnace off in
case of a blower failure. This control is a manual reset con-
trol, which can be reset only once. If the unit goes off on
limit a second time, contact a qualified servicer so the prob-
lem causing the control to open can be corrected.
