How can I tell if my furnace ignitor is bad?

To determine if your furnace ignitor is bad, there are several tests that you can perform to diagnose the issue. First, check to see if the ignitor is receiving power. This can be done with a multimeter, making sure to turn off the power to the furnace before testing.

If the ignitor is receiving power, then it is possible that the issue is within the control board. To test this, inspect the control board for any signs of burned or melted components, and check for power to the board.

If there is power, then the control board is likely the problem.

If there is no power to the board or the ignitor, then the issue is likely the limit switch, cad cell, or the transformer. You can test the limit switch, cad cell, and transformer by unplugging them and testing their continuity with a multimeter.

If they are functioning normally, then they are not the cause of the issue.

If all other components test as functioning normally, then the cause of the bad ignitor is likely to be the flame sensor or high-limit switch. To test either of these components, insert the pins of the multimeter probe into the two terminals of the component and then measure the voltage.

If the voltage is lower than what is required for the flame sensor to operate, then the flame sensor is bad and needs to be replaced. If the voltage is higher than what is necessary for the high-limit switch, then the switch is bad and needs to be replaced.

Overall, to determine if your furnace ignitor is bad, you should check to see if it is receiving power and inspect the control board for any signs of malfunction. Then, you should test the limit switch, cad cell, and transformer for proper function, and then test the flame sensor or high-limit switch with a multimeter to determine their operational status.

If any of the listed components are malfunctioning, then they need to be replaced before your furnace can work properly.
