Thank you for your time and knowledge. --73.19.xxx.xx

I DIY a lot and have a simple Flow chart for diagnosing HVAC systems. #1. Does it have power? Yes. Proceed to #2. #2. Does it have fuel? Yes. Proceed to # 3. #3. Call the pros. --24.152.xxx.xx

Hit reset. --204.10.xxx.xx

Reset is Section 1a. I forgot that part. --24.152.xxx.xx

First, pull the cover and look for a fault code. --75.75.xxx.xxx

A common problem is the device in the burners which is a thermocouple which generates current that opens gas valve. If defective there may not be sufficient current to open gas valve. Sometimes cleaning will work where it is better to replace. View some video on You tube on when burner does fire. Another problem is there no glow where you see it does not come on which heats the thermocouple. Remember this is safety as the gas valve will not open unless the two steps confirm the burners will ignite --216.110.xxx.xxx

I have a similar unit at my house. I had a similar problem. The board flashing error code said bad inducer motor. I pulled it myself, easy replacement. New motor cost just under $200. --136.61.xx.xxx

I turned off the A/C and turned off the thermostat. Turned the breaker off, waited a few seconds and turned back on. Turned the thermostat back on to heat and set at 76 degrees. Went outside to unit and it is doing the same as before in that it is calling for heat but the heat doesn’t come on. While it was calling for heat I turned the in line gas valve off and back on and even in between. I could hear the igniter trying to light the gas but it never ignited it. Of course after a minute or two when it doesn’t light the gas it turns off and stays off. Now the light on the circuits board is flashing 1 time about every 3 seconds. Doesn’t seem to be any pattern other than that. Not sure if it is because I cut the gas off for a second. --174.212.xx.xxx

One flash means Ignition error or flame failure. This could be due to a faulty ignitor, poor gas pressure, or inadequate airflow. The only commonality between your system and the neighbor is the gas supply. Have you verified the utility is on? --75.75.xxx.xxx

I just tried it again and get the same thing. I went around to look at the gas meter to see if it looked like gas was going through. There is an old stile odometer type reading and then there are 2 dials like a clock but nothing is moving. I am going to turn the gas valve to what I believe is the off position and try again. --174.212.xx.xxx

I've had one unit fail to light 5 or so years after the original installation because the installers undersized the exhaust vent and the pressure switch must have been right on the edge. After I changed the exhaust pipe to the proper size, it's been working ever since. --75.75.xxx.xxx

The utilities offices are closed for the weekend so I will have to wait till Monday to call them to see if for some reason they cut off the gas. --174.212.xx.xxx

If you're right and your gas isn't coming on, it's usually because there's a problem with your igniter. --73.2.xx.xx

--174.212.xx.xxx

There are3 burners but 2 ignitors. One on the top burner and one on the bottom. --174.212.xx.xxx

That's most likely the pressure switch that verifies the exhaust pressure is where it needs to be. If it didn't happen to be a loose or corroded termination, that pressure switch being open would be telling you there's an obstruction of some kind in the exhaust. --75.75.xxx.xxx

Thank you, Jason, for teaching me and guiding my hands. --73.19.xxx.xx

is there another gas appliance in the house you can confirm is working so you know the gas is flowing to the house? --38.248.xx.xx

Ken, everything else is electric. Good idea though. --73.19.xxx.xx

Some natural gas uses a spark ignition where other use a glow bar system that gets red hot. The flame rod sensor will generate current where the gas valve will not open. If there forced vent where the exhaust is induced by fan then will hear the fan running along with checking air flow at exhaust there are pressure switches where there must be sufficient air flow where check exhaust for obstructions which will cause inadequate air flow. Power vented equipment must have enough air flow to cause gas valve to open. Sometimes there is something that is obstructing that air flow where check to see with hand there is adequate air flow. A bird or other object can be in exhaust pipe. --216.110.xxx.xxx

I believe the Goodman has an LED light on the inside of it. If it is flashing RED, count the number of strobes. On the back of the front cover there will be a table that will get you pointed in one of seven or eight fault areas. --67.140.xx.xxx

Any chance the earthquake damaged the gas pipes somewhere, and you aren't getting any? --72.218.xx.xxx

Either way you have it going now. Test it off and on a few more times before the tenants move in and hope for the best. --107.147.xx.xx

Just glad I was able to get it going again even though winter is over here. I will check it again as well. --73.19.xxx.xx
