How to check for a false flame on a spark igniter?
Check for a false flame condition (short to ground) before each startup. If a false flame condition is present, the module does not allow startup. 2. Generate a potential of 30,000 V (open circuit) at the spark igniter for direct ignition of the main burner.
How can I tell if my furnace ignitor has gone bad?
In order to check the ignitor by testing the circuit and inspecting the furnace for visual damage, the furnace must be set at room temperature. 2. Turn Off The Furnace Turn the furnace off using the thermostat. 3. Switch Off Circuit Breaker Turn off the circuit breaker for the furnace, often located on the furnace or in the home’s main breaker box.
How to troubleshoot a direct spark ignition system?
1. Check for a false flame condition (short to ground) before each startup. If a false flame condition is present, the module does not allow startup. 2. Generate a potential of 30,000 V (open circuit) at the spark igniter for direct ignition of the main burner. Note: The S89A does not include a spark generator circuit.
What should the first test of an ignitor be?
The first test should be the ignitor spark test. The second test is a secondary coil resistance test. The third test consists of an input current test. The following is a step by step procedure to perform these tests. It is important that all three of these tests be performed. Turn off the power to the burner/appliance.
What should I do if I find an ignitor in my furnace?
If you’re comfortable getting up close and personal with your furnace, the ignitor can be a simple thing to find and repair. Before opening any panels on your furnace: Make sure to unplug the furnace from the wall. You don’t want any power to the furnace while you attempt to find the ignitor and replace it. Turn off the gas valve.

How to test for Spark on Carlin ignitor?
Connect a test power cord with a switch to the ignitor leads in the burner junction box. Turn on the test power cord switch to power the ignitor. Check for spark across the ignitor clip ends (see Figure 1). If spark occurs, proceed the secondary coil test below.
