S-313 CHECKING INTEGRATED IGNITION

CONTROL BOARDS

NOTE:

Failure to earth ground the furnace, reversing the

neutral and hot wire connection to the line (polarity), or a

high resistance connection in the neutral line may cause the

control to lockout due to failure to sense flame.

WARNING

The ground wire must run from the furnace all the way back

to the electrical panel. Proper grounding can be confirmed by

disconnecting the electrical power and measuring resistance

between the neutral (white) connection and the burner closest

to the flame sensor. Resistance should be less than 10 ohms.

The ignition control is a combination electronic and

electromechanical device and is not field repairable. Complete

unit must be replaced.

WARNING

These tests must be completed within a given time frame due

to the operation of the ignition control.

NOTE:

The models use

White-Rodgers 50X57- 289

1. Check for 120 volts from Line 1 (Hot) to Line 2 (Neutral)

at the ignition control. No voltage, check the door switch

connections and wire harness for continuity.

2. Check for 24 volts from W to C terminal on the ignition

control. No voltage. Check transformer, room thermostat,

and wiring.

If you have 24 volts coming off the transformer but receive

approximately 13 volts on the terminal board between (C)

and (R), check for blown fuse.

3. Check for 120 volts to the induced draft blower by

measuring voltage between Pin 1 (on the 2-pin connector)

and Line (Neutral) on the control board. No voltage,

replace ignition control.

4. If voltage is present in Steps 1 through 3 and the induced

draft blower is operating, check for 120 volts to the ignitor

during the preheat cycle. Measure voltage between Pin 2

(on the 2-pin connector) and Line (Neutral) on the control

board. No voltage, check pressure switch.

5. After the ignitor warmup time, begin checking for 24 volts

to the gas valve. Voltage will be present for seven seconds

only if proof of flame has been established.
