2.If the voltmeter reads voltage, the safety fuse and the fusible link are good.

3.Replace the fusible link when an open circuit is detected. An open fuse line indicates overheating in the flue collector or compartment.

4.Check for leaks of the flue collector, vent pipe, gaskets, and all connections.

5.Check the flue pipe for blockage.

6.Check heat exchanger fins for partial sooting.

5.2.7Testing the Fuse

To test the fuse:

1.Clip a lead of the voltmeter to the grounding terminal.

2.Touch the other voltmeter lead to the 24VAC terminal on the ignition control.

3.If there is no voltage, replace the fuse. A blown fuse is usually an indication of a short in the 24VAC circuit. It is important that the cause of the short be found and repaired. Do not jumper or bypass the fuse.

5.2.8Testing the Ignition Control (for spark ignition)

Caution

The ignition control and igniter operate on 120V power. Keep this in mind while servicing the heater, and take care to avoid electrical shock.

The ignition control provides power to the pilot, opens the gas valve when there is a call for heat, and senses when a flame is established. To test the ignition control for spark ignition:

1.Clip one lead from the voltmeter to the yellow wire terminal on the transformer.

2.Touch the other voltmeter lead to the red 24V terminal on the ignition control.

3.If the voltmeter reads voltage, the temperature control and the manual reset hi-limit switch are not keeping the heater from firing.

4.Make sure the pilot burner is positioned next to the main burner (see Figure 40) and there is no soot or dirt on it.

5.Make sure the electrode (part of pilot assembly) is clean, the terminal connection is tight, and the ceramic insulator lead is at least 3/8 inch (9.5 mm) from the heater chassis and other metal parts.

6.Check for proper spark gap.

Figure 40. Pilot location (spark ignition).

5.2.9 Testing the High Voltage Ignition Lead

Connections must be tight, and silicone rubber boots in place. Bare metal parts at the base of the manifold bracket must be at least 3/8 inch (9.5 mm) from other metal objects. To test the ignition lead:

1.Turn the control panel switch to on.

2.Make sure the temperature control is turned far enough to call for heat. There will be a loud clicking noise indicating the pilot electrode is sparking.

3.If no sparking is heard, pull the ignition lead from the ignition control and hold the bare terminal 1/8 to 3/16 inch (3.2 to 4.8 mm) from the ignition stud with a pair of insulated pliers (see Figure 41).

4.If a spark does not jump the gap, replace the ignition control.

NOTE: The ignition control cannot be repaired in the field. If it does not operate properly, replace it.
