A lot of times that's the flame sensor, it's usually dirty and can be cleaned with a piece of extra fine steel wool.

Tempstar pilot turns off


Based on your model number this furnace does not have a pilot light,instead it uses a hot surface igniter.typically it glows and when it gets hot enough the gas valve will open and the burners will light.When the igniter starts to go bad it will glow but not get hot enough to open the gas valve.If your furnace lights and the quickly goes out the flame sensor maybe dirty.

Heater unit will not ignite, will note fire up


Check your furnace by the electrical panel, there should be a blinking error light. Sometimes there is a legend to how many blinking lights means what. I had an issue with mine, read the code and it turns out it was hitting the high heat limit. Turns out my blower motor wasn't turning on. Replaced it with a spare and it was fixed. Find out what type of furnace, and google the name, model, and the words, 3 blinking lights. Does your furnace turn on at all? Does it start to go through the cycle then stop? This is the proper cycle of a furnace and what should happen.

Inducer motor kicks on, it runs for a little bit, about 3-5 seconds, then you should see a bright yellow glow, this is the igniter, shortly after, you should hear a click and the gas should start to flow, almost immediately it turns to a blue flame. Then your igniter should turn off and the blower motor start up.

Won't ignite


Be sure that that PVC vent pipe going outside is not plugged or trapped with water. If the vent pressure switch is not tripping the furnace will not ignite. Also be sure that you don't have a gas leak somewhere causing weak gas flow to furnace.

Main Fan won't turn off even with thermostat removed. Burner not


There is a chart with the wiring diagram and othere charts that will tell you what the 6 blinks are for. That should tell you what is wrong and what part you need. Sounds to me like the board has an issue or the gas valve is locked out.

No hot surface igniter


This is why swapping parts is never a good idea. It could be a board, pressure switch, or several other issues. I'm a service technician and realize that many furnace issues are difficult to diagnose over the phone, or internet.
Calling a qualified, NATE certified technician to diagnose and repair this properly is probably the best solution that I could suggest. Yes, there will be a bill and it will be expensive, but it will be a lot less so than changing out parts you might not need.

Goodman GMP075-3 ignition problem


OK, if the furnace is not lighting for even a few seconds, you have either a bad gas valve, bad wire, bad control module or no gas. The pressure switch is not the issue. Check all wires to the gas valve and look for 24 volts across them when the ignitor glows and you hear the click. Then test for 24 volts to ground. It could be a bad ground wire.

No ignition


Yes. Gas ignitors either spark or glow. Find a way to look at the ignitor, even if you have to use a mirror. If it sparks or glows, figure out why the gas isn't getting into contact with the ignitor. If it doesn't spark or glow, the ignitor is probably bad, but the controller might not be sending it electricity (bad controller). This is what electrical meters are for. Checking for voltage at the ignitor will tell you if the controller is telling it to ignite.
