7. The unit will deliver heat to the conditioned space until
the thermostat is satisfied.
8. The gas valve and combustion blower will be de-energized
when the thermostat opens.
9. There is an adjustable Heat Fan OFF of approximately
60/90/120/150 second delay (factory set at 120). The con-
trol module will de-energize the blower once the selected
time has elapsed. This allows any additional heat in the
heat exchanger to be transferred to the conditioned space.
RESET AFTER CONTROL LOCKOUT
Amana
®
brand PGA__C, PGB__C and PGD__C units built
prior to July, 1999, are equipped with the Honeywell "Smart
Valve" system. If the control senses a loss of flame, the con-
trol will automatically attempt to relight. A lockout occurs
only when the ignitor fails, roll-out switch, primary limit or
secondary limit opens. This causes the air circulation blower
to run continuously, and ignition is no longer attempted. When
this occurs, it may be necessary to reset the control by turn-
ing the thermostat setting below room temperature for sev-
eral seconds and then returning the setting to the desired
temperature. The roll-out and secondary limit are manual re-
set switches and require resetting before normal operation
can continue. A failed ignitor will require replacement. The
control may also be reset after a lockout by turning off the
electrical disconnect switch to the furnace for several sec-
onds.
IMPORTANT: If the furnace frequently has to be reset, it
means that a problem exists that should be corrected.

1. Remove wire connections from gas valve terminals.
2. Using an ohmmeter, test across the ignitor terminals,
(Terminals 1 & 2 on the Q3450 harness)
3. Should read continuity, if not replace ignitor.
4. Using an ohmmeter, test from flame sensor to ground on
the Q3450 harness.
6. If continuity is shown, replace pilot assembly.
7. Reconnect harness(es) to gas valve.
8. Restore power to unit.

9. Set thermostat to demand for heat.
10. Ignitor warn up is 5 Seconds. Amp draw to ignitor is 1 to
1.5 amps at 24 VAC. Use an Amprobe to verify current.
11. Using a microamp meter verify flame sense. Microamp
readings should be 0.3 microamps or greater.
12. Smart Valve will not allow main burner operation until pi-
lot is proven. NOTE: pilot positioning will affect pilot op-
eration and flame sensing characteristics. See S-314 for
proper pilot positioning
13. If pilot looses flame sense, valve will shut off main burn-
ers and attempt relight. The "Smart Valve" system will
not lock out from no flame sense, it will continue to at-
tempt relight.
