Hello,

I have a Goodman Gas Furnace and I live in a townhome and each townhome has it's own meter, however there is only one regulator (external) for the building. I do not know the model number. Here are my symptions: This is an intermittent problem. The ignitor glows, but the furnace does not light. But if I wait a couple of hours it will eventually light. I have had a tech out who thought I had too much gas pressure coming into the house, my energy provider came out and said it was fine. So, my tech installed an internal regulator, to control the gas flow, because we learned the current regulation now requires internal regulator if the energy company is providing 14?? (not sure of the term) of water column pressure. But installing the internal regulator has not eliminated the intermittent problem of the ignitor glowing without the furnace lighting. Any Ideas?

Are you using propane gas?

Has your tech as you call him tested the gas valve for proper operation? If not that for sure need to be done. Then since you have a tech he should check out the rest of the system paying close attention to the number of blinks on the circuit board stating the cause of the problem. Then refer to the diagram on the back of the blower door and post the number of blinks and what it states those blinks mean as listed on the diagram.

No I am not using propane gas.

I apologize if I used the wrong term (tech). I don't think he checked my valve or the circuit board.

Thanks,

This question is for HVAC1000,

What types of things (symptoms) should he be looking for on the valve?

Usually when you are in the 14 inches of water column you are using propane gas.

What types of things (symptoms) should he be looking for on the valve?

With intermittent problems it will be a very difficult time trying to determine the exact cause of your problem and also usually very time consuming. All standard testing that would be provided by a regular HVAC company should be performed but in all actuality the fault will have to be caught when it happens and that is why intermittent problems are so difficult to catch.

If the ignitor glows then I would be looking at the gas valve for the correct voltage during that time.
