opened front panel and no flame. Igniter not glowing.Checked coils ok.I am guessing maybe I need a igniter?

There are five major electrical parts involved in the heating process:

1. High limit thermostat (#17 on the gas valve break down diagram)
2. Cycling thermostat (#8 on the motor break down diagram)
3. Igniter (#4 on the gas valve break down diagram)
4. Flame sensor (#18 on the gas valve break down diagram)
5. Gas valve coils (#7 on the gas valve break down diagram)

How to find out which part causing the problem?

Pretty simple: all of these parts have to be tested for continuity in the above sequence.

The following article on our forum will explain in detail how to run a continuity test using either an analog meter or a digital meter - How To Check Continuity With Ohmmeter

If any of them is open – it has to be replaced.

Gas valve coils also could be tested by resistance. There are two coils – one with three terminals and one with two terminals.
1. Coil with two terminals should have 1220 ± 50 Ohms
2. Coil with three terminals if held with terminals in upper position:
a) across the left and the middle terminals – 1365 ± 25 Ohms
b) across the left and the right terminals – 560 ± 25 Ohms

- The part number for the high limit thermostat is AP275754

- The part number for the cycling thermostat is AP276896

- The part number for the igniter is AP3109449

- The part number for the flame sensor is AP2910747

- The part number for the gas valve coils kit is AP3094251

Thanks Gene. I guess I really did not need to ask this question as you have answered it so many times in this forum.My igniter was cracked.This forum was a great help made changing this part a very simple process. Thanks again.

I'm glad you were able to fix it.
